All available ways to charge a laptop in a car from a cigarette lighter

Cars have long ceased to be an unprecedented luxury, and turned into an important necessity, without which many modern people cannot imagine their life. In the car, people talk, eat and, of course, charge their gadgets. For this reason, the question of how to charge a laptop in a car belongs to the category of burning and interests very many.

Fortunately, manufacturers of accessories have provided all possible options, and filling the gadget with energy is possible both in expensive, new cars, and in old Zhiguli of Soviet times.

You need to understand how to charge a laptop in a car so as not to ruin the battery and achieve the desired result.

How to charge a laptop in a car via usb?

Most modern cars have built-in USB ports, which serve to connect phones, tablets and laptops to the vehicle’s multimedia host.

However, charging the laptop using USB will NOT work. The fact is that the voltage in such a port does not rise above 4.5-4.4 Volts. And in order for the slowest charging of a computer device to begin, at least 30-32 Volts is required (fast charging requires 120 Volts at all).

Therefore, charging via the USB port is not possible for purely technical reasons, and will NOT be further considered. But you can and even need to power a laptop from a cigarette lighter.

How to charge a laptop from a car cigarette lighter?

At the moment, there are three ways how to charge a laptop in a car from a cigarette lighter. Each of them has its own strengths and weaknesses, but all three methods are working and may well be implemented.

A specialized device capable of converting 12 volts from a car cigarette lighter into 220 volts, which are necessary for high-quality charging of computer devices. With its help, it is impossible not only to charge laptops, but also to use almost any equipment operating on electric energy.

The main thing is to use the adapter wisely. It is best if the car is started at the same time, otherwise the car battery will be discharged very quickly, which will be an unpleasant surprise.

  • Dedicated charger.

How to charge a laptop in a car from a cigarette lighter and not drain the battery? It’s very SIMple if you use a proprietary charger. There are universal models (usually made in China), but they cannot boast of special stability.

It is best to use a proprietary charger (different for each laptop manufacturer). With its help, you can quickly and without any fears charge a laptop, and at the same time DO NOT burn its ports, and does not drain the car battery.

In technical terms, such a device is a powerbank of increased capacity. All the need to connect it to the car’s cigarette lighter. It will be enough to charge it at home and use it at your own discretion. It is worth saying that from such a device, you can charge with equal success, and netbooks, and tablets, and mobile phones.

How to choose the right attachment for charging a laptop in a car?

If the question of how to power a laptop from a car battery is very acute, then you should weigh the pros and cons in order to make the right choice and get the really necessary device for charging.

In the event that you need fast and high-quality laptop charging, and the rest of the devices are NOT planned to be charged, then you should opt for a branded car charger. This is a rather expensive, specialized device, but it completely eliminates the risks of charging the device in a car. I bought such a device, there is no doubt that your laptop will always be in working order. The only drawback of branded laptop charging is the high price.

In turn, the 12-volt adapter is a universal soldier. It can be used to charge laptop computers, smartphones and tablets. This will not happen for centuries effectively, but still the charging will go on. The downside of such a charger is its gluttony. If you forget to start the car, then such an adapter will set the battery “to zero” for several tens of minutes.

Autonomous charging is versatile and safe. Its price is small, but at best it will only last for one-time laptop charges. After that, the autonomous charging will have to be charged.

As practice shows, the 12 volt adapter is the best choice, combining reasonable price and versatility.


Another universal connector designed by Intel and supports charging power up to 40 watts. To charge the battery with it, the user will need to find the Corresponding cord and “power” his device from the second one. equipped with the same outlet and having a sufficient charge.

How To Charge Your Laptop From Your Phone

That’s all. there are no second ways to charge the laptop without the original charging, without exposing it to the line. The user always needs to remember about safety. it is better to wait out a few hours or even days than, as a result of unreasonable actions, to think about where to find money to repair expensive electronics or purchase a new device.

How to charge a laptop without charging?

Consider proven methods.

Universal charger

If you have an original charger with you, but there is an outlet in the reach, a universal charger will help out. a power supply, to which several “attachments”.plugs are attached.

As in the previous case, the laptop owner needs to clarify in advance whether the charger is suitable for his model. and if so, feel free to use it. The main advantage of universal charging over portable batteries is the ability to SIMultaneously charge the car and work on it.

USB 3.1

As already mentioned, it will NOT work to charge a laptop using a standard USB connector. But the ports of the new standard, designated as USB 3.1 or Type-C, give such an opportunity: they operate at power up to 100 watts and conduct current in both directions. both from the device and to it.

Unfortunately, not all laptop models support this standard yet; the representatives of the “new generation” include:

  • Acer Aspire 5 A515-52G;
  • Asus VivoBook Pro 15 N580GD;
  • HP Pavilion Gaming 15-cx0000;
  • Lenovo Ideapad 330 17;
  • Apple MacBook Pro 13 “(2018) and others.

All the owner of such a device needs is to purchase a cable of the same standard, connect it to the donor device, and connect the other end to the USB 3.1 connector. charging will start automatically.

Car cigarette lighter

Another good way to charge your laptop without charging is to use the cigarette lighter in the car. To do this, you will need to purchase a special inverter adapter. for the charger plug, universal or with a suitable plug.

It should be taken into account right away: the cigarette lighter is NOT capable of providing high charging power, which means that the user will have to wait one and a half to two times longer for the battery to replenish. As in the first case, it is not recommended to charge the laptop and work on it at the same time.

How not to charge?

The attempts described above to charge the laptop, and not using the original charger, are ineffective, but also harmless. Things will be much worse if the owner of the device, relying on vague advice from the Internet, tries to:

  • Charges the battery directly from the wall outlet
  • Remove the battery and charge it from the mains or a second portable power source;
  • Use homemade adapters, plugs and so on.

All these options, with extensive experience and the necessary equipment, including all the same transformers, are feasible. however, they can in no way be attributed to the SIMple and accessible to the ordinary user. As a result of such experiments, if the owner is lucky, nothing will happen. and if there is a little less luck, the most insignificant problem will be that the screen on the laptop does not work.

Advice: if you really need to charge your laptop, but you have a charger with you, you can contact any service center for help. specialists for a small fee will NOT refuse to properly replenish the “reserves” of the battery.

No matter how it turns out to charge?

But before moving on to working methods, and, unfortunately, there are not so many of them, you need to talk a little about the useless, completely NOT worth the waste of time. The first of them. attempts to charge a laptop left without charging through a standard USB connector.

The owner, sadly realizing that when a phone, player or other portable device is connected through the port, not only data transfer, but also recharging is carried out, can conclude: why not try in the opposite direction?

It would seem that this is NOT more difficult than making wireless charging with your own hands, just connect a Charged smartphone or portable battery to the connector and wait a little. In fact, charging a laptop in this way will not work for two main reasons:

  • Unidirectional stream transfer. in accordance with the accepted standards, USB ports of generations 1.0, 2.0 and 3.0 are intended for recharging from the carrier, and not vice versa;
  • Too low voltage. even if the first limitation were removed (it is fundamentally possible to do this), 5 volts used to connect portable devices and, accordingly, 2.5-4.5 watts are clearly not enough to power a laptop, which requires about 15-20 volts and from 40 watts.

Without using the transformer, which for a user who wants only to quickly and correctly charge a laptop left without a charger, it will not work to solve the problem. which means that you need to finally remove your smartphone from the USB port and try any of the methods described below.

The second non-working option is the use of incompatible charging from a laptop of another model or a second manufacturer. After all, it’s not worth telling that companies use different power supply standards and external attributes in their chargers (even within the same line). plugs.

Important: the plug of a third-party charger, even of a suitable diameter, may have a different polarity or set of contacts. which means that connecting it to a laptop will not give a positive result.

In the best case, a user who dares to test it in practice will see that the laptop battery is NOT charging; at worst, it will ruin the battery, I will supply it with a current that is NOT suitable for voltage and power.

Be that as it may, before using someone else’s charging, it is worth looking at what voltage, current and power it provides (The corresponding data is located on the “box” in the center of the cord in the Output section), and compare with the recommended manufacturer. they are easy find it, turned the laptop over and found the factory sticker on the case.

How to charge a laptop without a charger?

If the keyboard on the laptop does not work or one of the USB connectors is broken, you will not be able to use the functionality of the device in full, and not by visiting the Repair Shop or not using your own engineering skills. Another thing is a suddenly discharged battery: just find an outlet and connect a charger. But a laptop charger is not always at hand; what to do in this situation. let’s try to figure it out.

Using a portable battery

As already mentioned, it will NOT work to charge a laptop from a SIMple power bank. not the contacts and current parameters. A user who has already faced the problem of the absence at the most inopportune moment of the original charging should purchase a special battery. more powerful, larger and, of course, more expensive.

When purchasing, pay special attention to the plug supplied with the battery: it must match the connector of the laptop. You can clarify compatibility with the seller or in the accompanying documentation; even better. find a battery with a universal set of input contacts.

Then the user only has to find his own version and connect the portable charger to the laptop’s power port. It is better to leave the device alone while replenishing the battery. not every battery is capable of providing high-quality charging and the ability to work at the same time.

Tip: As an alternative to the standard battery, the laptop owner can use a mobile solar battery. of course also equipped with a suitable plug.

We use direct connection

By analogy with the first method, this method is extremely radical and is intended for users who, at least, had experience with the topic or other electrical devices. Despite this, of course, even a beginner can cope with the required tasks, however, if the slightest doubt arises, it is better to go directly to the next section of the article.

The laptop can become unusable from improper actions and violations of safety rules.

Moving on to the essence of the direct connection method, it is important to make a reservation on the paucity of existing methods. As a result, whichever of the charging options you choose, you face certain requirements, in general, equivalent to buying a new charger.

Having decided on the priorities, you will need to prepare in advance a couple of small wires with soft copper conductors and any sufficiently powerful external block of questions, the voltage from which, at least, should be equivalent to a standard adapter. Here, Note that if there is a lack of voltage, the charge will still flow to the battery, but not completely.

The lack of voltage of the used power supply is likely to manifest itself in a significant decrease in the performance of the laptop.

To avoid problems, work with the laptop turned off and the power adapter unplugged. It is also advisable to remove the battery, Until the electricity transmission channel to the laptop is established.

    In modern realities, any laptop or ultrabook is equipped with a round-shaped charging jack.

To take advantage of this, you need to connect the prepared wires to the input pins on the laptop.

  • Regardless of the type of laptop, the polarity in the contacts is as follows:
    • Centre. “”;
    • Edge. “-“.
    • The neutral line usually goes through the negative contact.

      One way or another, your goal is to fix the wire on the middle segment of the charging socket by any means.

    • With the negative pole, you need to do the same, but in this case, the wire should only contact the side metal frame.
    • Additionally, make sure that the contacts do not cross each other, for example, by using a multimeter.
    • Having finished connecting the wiring, you can tackle the power supply depending on its value.

        If you use the selected power adapter and need it in the future in its entirety, you will need to perform the same steps as described above, but in relation to the plug itself.

      In our case, the round output of the adapter is taken into account, since in other cases the connection can cause many difficulties.

      As with the jack, it is required to connect the wire assigned by the plus to the middle of the plug.

      The negative phase must intersect with the outer bezel of the power supply output.

      In addition to what has been described, you can do a little differently.

        Remove the original output from the adapter and clean the wires.

      Holding the resulting contacts in line with the correct polarity.

      Be sure to insulate the connection points to avoid possible short circuits.

    • Next, you need to power the power supply from the high-voltage network and make sure that the created recharging circuit works stably.
    • When the adapter you have chosen is slightly more powerful than the original one, you should take special care to prevent overheating of the laptop components and the battery itself.

      On this, in fact, you can finish with the method, since after following the recommendations, it remains only to install the battery and wait for it to be fully loaded.

      Charges laptop without charger

      In view of the fact that the actions of charging a laptop without a power adapter require direct intervention in the operation of the laptop, it is important to make a note regarding the automatic solution of problems with turning on the device without using a battery and charger. Thus, after careful study of the instructions, you can not only replenish the battery energy, but also make the laptop work without a built-in power source.

      Among other things, you should understand some additional aspects related to possible computer malfunctions and directly related to the premise of the need for this kind of charging. Going deeper into the essence of what has been said, before following the recommendations from the instructions, be sure to make sure that the laptop is in good working order.

      Be extremely careful when performing any actions that were NOT originally provided by the manufacturer! In general, even after strict implementation of the recommendations, we cannot guarantee that the device will be charged to the normal level. over, complications may well occur, for example, in the form of a short circuit and burnout of the internal components of the laptop power supply.

      Using USB ports

      As you know, today there is a fairly large number of possibilities. Standard USB ports are available on literally any laptop. These additional features rightfully include charging the battery without using the original charger.

      You can find out about the presence of such an input by reading the technical specification from the computer, which describes all the available ports. Usually the required socket is named USB 3.1 (Type-C).

      So, how to charge a laptop without charging via USB:

        Get a dedicated external power supply that allows you to connect to a USB adapter.

      Also connect the prepared USB cable to the power adapter and laptop.

      Ask the device from the high voltage network and wait for the charging process to complete.

      Of course, thanks to this approach to replenishing energy in batteries, you can use all the capabilities of laptops without any visible restrictions.

      We use Autoinverter

      Many car owners and at the same time laptop users have faced the problem of lack of standard battery charge when actively using the computer on the road. In this case, the ideal solution to the problem is a special car converter that converts the base voltage of the vehicle.

      It is worth making a reservation here that you can use such a device both with a standard power adapter, and without it. However, given that in your case, most likely there is a charger at all, you will need an additional USB adapter.

        Connect your car inverter according to the instructions supplied with this car gadget.

      Use a USB adapter to connect the laptop to the Corresponding connector on the inverter.

      As in the early case of Power Bank, the type of USB port used has a significant impact on the charging process.

      In addition to the above, it is quite possible to purchase a car power adapter for your laptop and charge your computer with it through the cigarette lighter. However, such power supplies are usually supported by a limited number of laptop models.

      This method, as you can see, is rather additional and is suitable as a solution in isolated cases.

      How to charge a laptop without a charger

      We use an external battery

      This method, unlike others, allows you to charge your laptop not only at home, but also in any other place. What’s more, you still DO NOT need a standard laptop charge.

        In order to use this method, you need to purchase a special external battery, the power and cost of which depends on your requirements.

      The dimensions of such a battery can also vary significantly and depend on the same criteria.

    • The battery itself is charged through a special power adapter from the high-voltage network.
    • Please note that the external battery, called Power Bank, is designed to recharge not only laptops, but also other portable gadgets. Depending on the type of battery purchased, you can recharge multiple devices at once.

        Connect a special USB adapter to a pre-charged Power Bank.

    • Do exactly the same with any convenient USB port on your laptop.
    • Here is the functionality of the port used depends on the speed and stability of the process of recharging the laptop battery.
    • The devices shown in the screenshots within the framework of the article are NOT recommended. the choice depends only on you.

      Using this approach, especially if you have multiple drives, you can increase the standard limit of the laptop battery to the level of the standard power adapter.

      Charges battery without laptop

      This method of charging a laptop consists in disconnecting the battery itself from the laptop and, by using some tools, replenish the energy supply. In this case, you may still need a laptop power adapter, which, however, it is quite possible to replace it with any other one that meets the requirements of the technical specification.

      Please note that as part of our detailed instructions for this method, we also considered replacing the battery with a new component. Based on the topic of this article, these notes may well be useful, since by replacing the old discharged battery with a charged new one, it is possible to restore the laptop to its full functionality.

      We use an electric generator

      In modern realities, many users resort to using gadgets such as solar panels or any other portable generators in order to charge their personal devices. This attitude towards such types of recharging is quite justified, since the battery is often replenished quickly enough.

      READ  How to connect Wi-Fi on a Samsung laptop

      The main negative feature of such gadgets is their dependence on certain weather phenomena, which makes it somewhat difficult to use at home.

      In our case, this is a solar battery, due to the maximum compactness.

      When the device is with you, use the appropriate adapter to connect the power generator to the charging socket of the laptop.

      Usually the required set of adapters is supplied with the gadget.

      After connecting, make sure that the source works without any problems.

    • For some amount of time after the start, energy will gradually transfer to the base laptop battery.
    • Such generators are capable of maintaining voltage in themselves, being a kind of Power Bank. That is, for example, you can leave a solar panel in the open air and soon it will be able to power all your devices.

      Storage capacity depends on generator model.

      This completes the instructions.

      Regardless of the method you choose to charge the battery, you can replenish the battery’s energy reserve. And although all methods are quite equivalent, in the absence of the necessary parts and known to be much more profitable, it will still be more profitable to get a new power adapter.

      How fast is charging

      On average, charging from a power bank lasts about 3 hours, but if the capacity of the laptop battery is too large, it can take a long time before the battery is fully restored. When using modern laptops, this indicator does not really matter, because while charging the battery, the device can be used in normal mode.

      In addition, the recovery of the battery charge in this way can be carried out while moving or in a room NOT equipped with electrical outlets. Charging a laptop via Power Bank will be successful only if the external battery itself has a sufficiently high level of accumulation of electric current.

      To avoid a situation when at the right time the capacity of the bank will be insufficient to connect consumers to it, you need to regularly connect it to a special adapter or purchase a device with a solar battery.

      Why it is impossible to charge a laptop with a power bank from the phone

      When buying a Power Bank for a laptop, pay attention to the designation on the packaging and label. SIMilar products are available for charging mobile phones, so it is easy to get confused and purchase an unsuitable device for use. You cannot charge a laptop with a power bank from the phone, because the output voltage of such a device is only 3.7 Volts.

      If the telephone Power Bank has a sufficiently large capacity, then you can try using a special converter to raise the voltage from 3.7 to 19 Volts. For such a connection, you will need to connect the output contacts of the power bank to the converter, which should then be correctly connected to the socket of the laptop. Of course, this is not worth doing, it is better to immediately purchase a normal external battery.

      Is it possible to charge a laptop from Power Bank

      The easiest way to restore the capacity of a laptop battery without using a charger is to connect an external battery. This product has the following advantages:

      • Large capacity.
      • Compact size.
      • Light weight.
      • High reliability.

      Although the cost of such products is NOT low, the costs of not being able to continue to work on a laptop can be significantly higher. The uninterrupted functioning of a laptop is especially important for freelancers, whose work is completely carried out remotely.

      The capacity of such a product is sufficient to maintain the laptop in working order for a day or more, therefore, during this time, you can replace the charger or repair it.

      Its compact size and light weight are especially important when traveling. With the help of such devices, you can charge your laptop in nature or in a hotel room. When traveling abroad, the bank will allow you to avoid the need to purchase adapters for electrical outlets.

      High reliability and long service life will allow using the device for a long time, and low self-discharge. always have a fully charged and ready-to-use backup energy source at hand.

      How to charge a laptop from Powerbank

      Modern laptops can work on a single battery charge for several hours in a row, but then the device will automatically turn off if you DO NOT connect the laptop to the network through the adapter in time.

      For many reasons, such an opportunity may not be available, so each owner of a laptop should take care of alternative ways to restore battery power in advance.

      What to look for when choosing

      When buying a new power bank, you must choose a model designed for charging laptops. Phone devices are NOT suitable for this purpose. Next, pay attention to the following characteristics:

      Capacity. This parameter determines the number of laptop battery charges without connecting the power bank to the network. The capacity of such products is indicated in milliamperes, but the minimum value should be around 20,000 mA. As a rule, the higher this indicator, the higher the cost of the device.

      The number and type of ports. If from Power Bank it will be possible to charge not only a laptop, but also a phone, then it is enough to purchase one powerful device to, if necessary, charge all devices running on lithium batteries. The number of ports is also important in this case, because in the event of an emergency power outage, it may be necessary to charge several devices at the same time.

      Weight and dimensions. If you often have to take a power bank with you, but there is no need for a high power of the product, then it is enough to purchase a device with minimum capacitive characteristics. Weight and dimensions are always in direct proportion to THESE parameters.

      Body material. The body of the product must not only be shockproof, but also protected from moisture and dust. Only in this case, it is impossible without fear for the safety of the device to use it on long journeys and hikes in nature.

      Manufacturing company. If you decide to purchase a powerful device equipped with a large number of ports, then it is better to give preference to products of well-known brands. Power Bank produced by firms that value their reputation will work the manufacturer’s recommended service life without any serious deviations in performance.

      To buy such a product, you should contact only proven and well-established trade organizations, otherwise you can easily run into a fake.

      Power Bank is a functional device that allows you to replace a standard adapter. In addition, some models can be equipped with a flashlight, as well as an outlet for connecting car gadgets, which will allow NOT to use the battery while the car is parked.

      How can you charge your laptop without charging

      Now you will NOT surprise anyone with a laptop. It has long become an integral part of modern man. Every day we can observe people sitting in a park or cafe working behind it.

      Its difference from a computer is the ability to work without a constant connection to the mains, but sooner or later, the battery will run out and you will need to replenish the energy supply. Many of us will close the laptop and move on calmly.

      Now let’s try to figure out how you can charge a laptop without charging.

      Charging methods

      At this stage of its development, mankind has come up with several ways to charge a laptop without a charger (charger):

      • Solar panels;
      • External batteries;
      • Charge in a car with a portable inverter.

      Let’s consider each method separately and analyze its positive and negative sides.

      External battery

      An external battery is a portable device that, like solar batteries, can increase the operating time of our laptop up to two hours. A standard lithium-ion laptop battery can hold a charge for 2-3 hours, but with an external battery, the energy fund doubles.

      Manufacturers provide us with a huge range of such batteries, which differ from each other, both in size and in energy supply.
      The unconditional advantage of this method is that regardless of the weather outside the window, you can always charge, unlike solar panels.

      In most cases, all kinds of adapters are included in the kit, which will allow you to charge more tablets, cameras and other equipment.

      Charge in the car

      This method is perfect for owners of laptops with a car. The only thing you need besides a car is a portable inverter. Due to the fact that the car usually has sockets, so you will NOT do without this device.

      The advantages of this method include the fact that you need to carry unnecessary equipment (solar batteries or external batteries).

      Serious disadvantages include the fact that charging is possible only when the car is running. It turns out quite expensive.

      Solar panels to help

      If you are a fan of spending the weekend in nature, and not within four walls, and you SIMply cannot do without a laptop, then one of the solutions to the problem may be. purchasing a solar battery.

      This device allows the energy received from the sun’s rays to be converted into electricity. The installation process is very SIMple. for this you just need to connect it to the power connector.

      There are two types of solar panels:

      • Portable mini-battery. small in size, but have a small amount of power reserve;
      • Batteries capable of maintaining a large number of equipment in working order. A serious drawback and, perhaps, the most important is its large size and complexity in the installation process, which is not quite suitable for picnics.

      Review of tariffs of the operator Beeline for the tablet. Further.

      The advantages of this type of charging include the fact that with its help the operating time of our equipment can be extended by a couple of hours. Truly maximum work efficiency, only obtainable in good and clear weather.

      Among the disadvantages, it should be noted that it is impossible for us to work or have fun with the laptop while charging. This is explained by the fact that the voltage value is a changeable value. This type of charging can be justified only in cases of long exposure to sunlight.

      Battery for Charging

      Laptop charging does not charge, what to do?

      In the event that our charger, for any reason, has ceased to perform its direct duties, do not rush to run to a computer service

      Try to do the following:

      • Repair the adapter;
      • Check the cable for mechanical damage;

      Despite the fact that self-repair has its pros and cons, it should be resorted to first of all by those people who understand electronics and can personally find the cause of the charger malfunction. If you are NOT that strong in this business, then it is better NOT to take risks and take your laptop to a service center. Otherwise, you risk making it even worse, which will result in additional repair costs.

      These are the main ways to help you charge your laptop without a charger.

      The computer lags what to do. The answer is here.

      Charge from a universal portable battery

      To charge a laptop from Power Bank, you need to know how to properly “interact” with a portable device. This is an important point to consider before charging your laptop. So, the cart must be charged up to 100 percent before use on a laptop. If the device was recently purchased, it should be fully charged and discharged for optimal battery performance in the future.

      If the device has not been charged to 100 percent, then there is a special sense in trying to charge the laptop, because it will be discharged much earlier than the laptop battery is full. An exception to this rule would be car cans with a battery capacity of 20,000 mAh and above.

      How to connect voz-bank to laptop correctly

      To find out how to connect the Power Bank to a laptop, you should take into account the above requirements for the portable battery accessory device and your personal computer, as well as find out what ports for connecting various devices are available on your laptop.

      Based on the above, the question arises: how to connect the Power Bank to a laptop if you are NOT the owner of a laptop with the Type C 3.1 port available on it? The answer to this question is this: subject to the necessary characteristics of your charger, you need an adapter from the car-bank to the connector for charging the laptop.

      It is unlikely that the adapter you need will be included with the charger. it should be purchased separately. If you have a suitable adapter for a laptop Power Bank, then from port 2A through a cable it must be connected to the power connector on the laptop.

      How to choose a Power Bank to charge your laptop

      To understand the question of whether it is possible to charge a laptop from Power Bank, you should make the right choice when buying it. When buying a mobile charger, pay attention to original devices with high-quality rechargeable batteries from popular manufacturers.

      As a rule, the Chinese counterfeits have low quality batteries. At the same time, manufacturers of such devices promise the consumer a capacity of 20,000 mAh, but in reality, the promised volume available to the user is not observed. Accordingly, the output current on such a device will be low and will definitely not be enough to charge the laptop. By the way, connecting such a Power Bank to a PC will be very problematic.

      The average laptop has a battery with a capacity of 10,000 milliampere-hours, so for the effective use of a portable charger, either its capacity is SIMilar or slightly less. This will allow you to charge your laptop, if not 100 percent, then at least 70-80, which is a fairly good result.

      Is it possible to charge a laptop from Power Bank

      A laptop is a convenient portable device that we can take with us both to work and when traveling. But the problem lies directly in the charge of the battery, the volume of which, at best, lasts 3-4 hours. When asked if a laptop can be charged from Power Bank, the unequivocal answer is yes! Technologies are improving every year, and now no one will be surprised at the creation of a portable charger (Power Bank), which can level the lack of a nearby power source, which solves many problems for the laptop user.

      It should be noted that NOT every such device can become your faithful assistant when charging your laptop. To do this, the Power Bank must have the necessary characteristics or be specialized for a laptop charge. Let’s figure out how to charge a laptop via Power Bank.

      Connecting Power Bank to laptop via USB

      Many vo-bank users think that this device can be connected to a laptop via a USB cable. This is indeed possible, provided that you have the latest USB 3.1 port on your laptop. This type of connection also has another name.Type C.

      If your laptop has the above connection type on board, but only USB 2.0 and 3.0, then under no circumstances will you be able to charge the laptop through a “USB cable”. The reason for this is quite SIMple: ports 2.0 / 3.0 have a voltage transfer of only 4.5 volts, for a tablet and a smartphone this power may be suitable, and to charge a laptop at least 30, and best of all. 50 volts and above.

      Efficient laptop charging with Power Bank

      Considering the efficiency of charging a laptop from a portable battery, we can say with confidence that this method is very good. It makes it easier to use a laptop without access to the mains electricity.

      Just imagine how pleasant it is to use a laptop at work or when moving to another city without a power supply. Your laptop battery plus the capacity of your portable battery is very convenient. This approach will give you about 5-8 hours of operating the device without connecting to a power source during the use of a laptop.

      Often, owners of a portable charger wonder how to charge a laptop using Power Bank. To do this, he must have the characteristics that will be described below.

      To charge, the device must have an output voltage of 18 to 20 volts and a rated current of two amperes. Not all portable chargers have these parameters. As a rule, the exception is made by Chinese fakes of popular models and manufacturers of car banks.

      In order to accurately select a device for charging your laptop, pay attention to the following things:

      • The presence on the case of ports for connecting a USB cable in 1A and 2A. The letter (A) following the number means amperage, which gives this port at the output. They can also be used SIMultaneously, and the figure, respectively, indicates the number of Amperes.
      • For comfortable operation of the charger and laptop, the charge-bank must have a storage battery capacity of at least 10,000 milliampere-hours (mAh).
      • The Power Bank must have a cable for charging a laptop with a certain size, so pay attention to the accessories of the adapters: they must be suitable for the device you want to charge. Otherwise, it will not be possible to connect even a charger that is appropriate in all respects to a laptop.

Thanks to this invention, the problem of restoring the charge of a mobile device is easily solved. Can I charge my laptop with Power Bank? This question still arises for many people. The article will discuss in detail the solution to the problem in the possibility of charging a laptop using a portable Power Bank charger.

      So, you got the answer to the question of whether it is possible to charge a laptop from Power Bank. In this article, we found out the required characteristics of a portable charger to recharge a laptop, and also fully figured out how to connect a universal charger to a laptop.

      Arguments for charging from a computer:

      • The ability to stay connected. Sometimes you need a few percent of the charge to make an important call or send a message. It is enough to connect the smartphone to the nearest computer and replenish the battery of the device.
      • Convenience. If there is a computer nearby with several free USB ports, you do not need to look for a free outlet or install an electrical splitter.

      What happens if you charge a smartphone from a laptop

      Modern phones have improved a lot, but users have to pay the price for new features with short battery life. If you constantly use your smartphone for entertainment, browsing the Internet or making phone calls, the battery usually discharges in half a day (5-7 hours).

      A message appears on the screen asking you to connect the device to the electrical network, and here a problem arises. often there are free sockets nearby. You can always recharge your phone from a computer or laptop. just use the USB port. We will look at the advantages and disadvantages of this method.

      What if, the USB port stops working after charging

      Sometimes the phone puts a heavy load on the USB port, and it stops working, as if it freezes. In such cases, the message “The USB device is not working properly and has exceeded the power limits for its hub port” might also appear. Then it is better to disconnect the phone from the computer and it is from it that it is better not to charge. In the window with a message about the problem, click the “Reset” button, if any.

      Even after stopping charging, the USB port may still NOT work. In this case, you can:

      • Go to Device Manager
      • Find a broken USB Root Hub, which will be marked with an exclamation mark
      • Go to Properties. Nutrition “:
      • Press the “Reset” button.

      Difference between charging from USB 2.0 and 3.0 connectors

      Most modern computers have modern USB 3.0 ports. This connector allows you to charge your phones faster thanks to the increased current of 900mA. The outdated analogue (USB 2.0) had an indicator of 500 mA, which is why smartphones were charged from computers very slowly. If it is important to quickly get a few percent of the charge, connect your phone to a modern USB port (3.0). Typically, such a USB port is blue inside.

      Arguments against charging from a computer:

      • Virus Infection Threat. If you connect your smartphone to someone else’s computer, you can accidentally get a dangerous file. a virus. To insure against the problem, before connecting, open the phone settings section and select the “Charge only” mode. This function blocks the transmission of information.
      • Slow charging. The USB ports on your computer are NOT capable of providing the required current to charge your mobile phone, so the battery charges slowly. Sometimes you need to wait a few hours for the smartphone to reach at least 50 percent of the charge.
      • Battery worn out. Some users have noticed that with frequent recharging from a computer, the smartphone battery starts to drain faster. That is why phone manufacturers recommend using original chargers to fill the battery with energy.

      In total, in 99% of cases, you can recharge your smartphone from a PC or laptop without any fear, especially if you need to make an important call. I recommend using this feature when needed, rather than constantly. Otherwise, it is possible, albeit unlikely, but the risk is infection of the device with viruses and the rapid depletion of battery resources.
