How to connect a laptop to a car through a cigarette lighter

Charging in a car or how to connect a laptop in a car

For most car enthusiasts who use a laptop in their car, the actual question is: how to connect a laptop to the car’s cigarette lighter in order to use the device while traveling? Someone plans to carry out work activities using a mobile gadget, others use it as an entertainment system, but everyone is faced with the problem of a limited working resource of a laptop due to the low capacity of its battery.

Depending on the model, the continuous operation time can be 3-7 hours, and then you need to look for alternative power sources to recharge it. Of course, some car owners have a 220 V socket in their car, but, as a rule, it is located in the luggage compartment, which makes it inconvenient to use it, because it is necessary to stop, often, remove things from the trunk or move them in order to connect the laptop to the outlet Also, the method of placing the device will be unsafe, because it can be damaged mechanically or fall down during sudden acceleration or deceleration. However, there are effective ways to connect a laptop through a cigarette lighter.

How to connect a laptop to a car through a cigarette lighter using an inverter?

An inverter is an electrical voltage converter that allows you to get 220/230 V necessary to power a computer from 12/24 V of the car’s on-board network. Such a device is very efficient, but it is large in size, which makes its presence in the car quite inconvenient, because the inverter must be placed somewhere. However, it can be connected both through the cigarette lighter and through the car battery terminals, because special clips are usually included in the delivery set.

The inverter gets very hot during operation, so some of the energy is spent on heat losses. Modern devices are characterized by high efficiency, which reaches 95%. The cost of the equipment is quite high and it depends not only on the manufacturer of the device, but also on its power. To ensure full charging of the laptop battery, you can use devices with an output power of 200/300 W. Of course, there are 600 W inverters, but they are designed for more energy-intensive equipment and their use is not advisable.

The resource of such a device is large enough, so its life cycle is long, but is it worth using it? With all the obvious pluses, there are many and minuses, one of which is that it is necessary to allocate a special place for it. An intercooler is located in the inverter housing, which cools the internal winding of the device with air, therefore, for unhindered heat dissipation from the device, you should choose a well-ventilated place in the cabin, as well as hide it from the sun.

How to connect a laptop in a car through a cigarette lighter using an adapter?

An auto adapter for a laptop provides full charging of the gadget. The only caveat when using it is that it cannot be connected when you are working with the device. This applies to those users who use laptops with broken or damaged batteries. It will not provide the laptop performance you need. This also differs the adapter from the inverter. The advantages of the equipment include:

  • Ultra-small overall dimensions.
  • Low power consumption from the on-board network, which does not increase the load on the generator.
  • Does not cause noise interference with other electronic devices in the car.
  • Practical and easy to use.
  • Most adapters have a USB port for charging your phone.
  • Differs in low cost.

Of course, an adapter is a great alternative to an inverter. Its cost is much lower, and its service life is very high, so it can certainly be used for many years. However, like all technical devices, its parts are subject to natural wear and tear, so the equipment will have to be replaced sooner or later. However, the same applies to the inverter. By the way, each adapter is designed for a specific laptop model, as evidenced by the output connector.

We hope that now you understand: how to connect a laptop to a car for charging and this process will not cause any difficulties. Regarding which equipment to choose, it is definitely difficult to answer here, because everyone decides for himself, but in a car, most likely, it will be most practical to use an adapter instead of an inverter.

CONNECTING THE LAPTOP TO THE CAR LIGHTER

CONNECTING THE LAPTOP TO THE CAR LIGHTER

To power a laptop from the car’s mains, a voltage adapter is required, since a car has 12 V, and to power a laptop, 18-19 volts are usually required. There are voltage converters for connecting a laptop from the on-board network of a car, which have a fairly high cost, from 50 and more. The described converter will cost you much less. over, most of the parts can be borrowed from an old power supply unit from a computer. Assembling time will take a little.

An integral timer KR1006VI1, an imported analogue of LM555, is used as a PWM driver of the voltage converter. From its output, the signal goes to the key, it is also a field-effect transistor VT1. The conversion frequency is determined by the capacitor C1, and with the capacitance indicated in the diagram, it is approximately 40 kHz. The duty cycle is controlled through the 5th output of the timer. Some types of imported analogs of the timer have a different control scheme for this input and therefore may not work correctly. Instead of a 45N03 pole, you can use BUZ11, CEB603, CEP703, NDP406, IRFZ33 and many others, with a maximum voltage of at least 40V, a maximum current of at least 15A, and a TO-220 case. VD2. paired Schottky diode with a reverse voltage of at least 40V and a maximum current of at least 15A, in a TO-220 case. For example SLB1640, or STPS1545. Diode VD1. protection against polarity reversal, direct current not less than 6A. Instead of a transistor VT2, for example KT315. Zener diode VD3 determines the output voltage of the converter. One of the most crucial details. choke, wound on a ring of powdered iron, with a diameter of about 27 mm, used in computer power supplies as a group stabilization choke. It has 21 turns with three PEV-1 wires with a diameter of 0.75mm folded together. The choke has an inductance of about 44 μH and a resistance of about 0.1 ohm. A metal box from a 50-watt electronic transformer is used as a housing to power 12V halogen lighting lamps. Its dimensions are 67x46x30 mm. In this case, instead of two half-bridge keys, you can conveniently place a field-effect transistor and a diode in order to press them against the wall of the case for a heat sink. The transistor and diode must be insulated from the case with a fluoroplastic or mica gasket.

The efficiency of this converter, with an output current of 3A, is 95%. In less severe modes, the efficiency can reach 97%, it strongly depends on the quality of the choke, VT1 and VD2. However, an increase in efficiency makes sense only to reduce the heat generated by a field-effect transistor, a Schottky diode and a choke. At the specified efficiency, during long-term operation, the converter housing has a temperature of about 45 degrees Celsius.

You should pay special attention to the quality of the connectors, as a significant current will flow through them. Also, the wires, especially those going to the input connector from the cigarette lighter, must be selected with a cross section of more than 1.5 sq.mm.

This converter is currently used in conjunction with Compaq Evo N610c, Compaq Armada M750 laptops, as well as several Rover models.

How to charge a laptop in a car via USB?

Most modern cars have built-in USB ports, which are used to connect phones, tablets and laptops to the car’s multimedia head unit.

However, you won’t be able to charge your laptop using USB. 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.

Universal adapters: what is their advantage?

There are also universal adapters in which the voltage value can be adjusted using the output switch. The main advantage of such devices is that the compatibility of electrical parameters is not at all important here. They are produced in two versions:

  • With an output current of 4.7 A;
  • With an output current of 3.7 A.

The first version is designed for laptops with a diagonal of 17 inches, the second for a diagonal of 15 inches.

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 all the pros and cons should be weighed 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. Having bought such a device, you can be sure 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 as efficiently, but it will still charge. 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” in a few tens of minutes.

Autonomous charging is versatile and safe. Its price is low, but at best it will only last for one laptop charge. After that, the autonomous charging will have to be charged by yourself.

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

How to power a laptop from a cigarette lighter using a specialized adapter?

The adapter works on the same principle as an inverter, only it is impossible to use it to charge a laptop directly from the car battery. Although the principle of their functioning is almost identical, the adapter has more significant competitive advantages:

  • It has more compact dimensions, which greatly simplifies the ease of use.
  • Differs in the required output power and protects the charged device from impulse voltage surges in the on-board network.
  • Each laptop model uses its own charger.
  • The case practically does not heat up when charging.
  • Lower cost and design life of the inverter identical to the inverter.

Using the adapter, you can greatly simplify the process of charging your device. However, it is worth remembering that the adapter will only help to charge the laptop. It is recommended to disconnect it from the network when you turn on your computer. But even such an element will allow you to ensure mobility when using your device in various conditions. Another advantage of the adapter in comparison with the inverter is that the inverter is activated when the ignition is turned on, and when the engine is started, it is de-energized, which can lead to a short-term disruption of the charging process. Also, when the laptop is powered from the network, it is necessary to periodically start the power unit of the car, because the power consumption of the device is quite high. There are no such features in the operation of the adapter. In addition, they can charge the device through its USB connector using a special adapter cable.

Now you know how to power a laptop from a car battery and how to charge a laptop in a car via USB. Even an inexperienced user can cope with such a process, because there is nothing complicated in it. I hope you received a complete and comprehensive answer to the question: how to charge a laptop in a car?

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, you can not only charge laptops, but also use almost any equipment that runs on electrical 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 do not drain the car battery.

In technical terms, such a device is a powerbank of increased capacity. There is no need to plug it into the car’s cigarette lighter. It is enough to charge it at home and use it at your own discretion. It should be said that from such a device, you can charge with equal success, and netbooks, and tablets, and mobile phones.

How does a cigarette lighter work

A car cigarette lighter consists of two devices. a heating element and a connector (plug) in a convenient housing. It can be directly connected to the battery, so the device works even if the ignition is turned off. In addition to the main purpose, the plug is often used as a 12/24 volt outlet, to which a splitter is connected, which provides power to a laptop, phone or other devices. A splitter is also connected to it, so you can simultaneously charge a laptop, phone or use a DVR. The splitter or power supplies of these devices are inserted into the plug, which provides a reliable connection with the contacts of the cigarette lighter socket.

How to properly connect the cigarette lighter

A cigarette lighter is an essential attribute of any car. Often there is a need for an additional cigarette lighter located in the trunk or on the panel next to the main one. Through the splitter, you can connect up to 3 different devices to one cigarette lighter. An additional cigarette lighter is connected directly to the battery. After reading the article, you will learn how to connect the cigarette lighter in the car correctly without harming your car.

What you need to insert a cigarette lighter

If you decide to install an additional cigarette lighter, then you will need the following tools:

Connecting a cigarette lighter

Never plug the cigarette lighter into the ignition. The ignition system will not be able to withstand such a load. Having laid the wire in the engine compartment, bring it to the positive contact of the battery, connect the fuse and then attach it to the terminal. If for some reason you cannot do this, lead a fused wire to the starter and attach it to the positive terminal of the relay. Strip the end of the wire at a distance of 1 cm, place it on the terminal, then crimp with pliers. Be sure to secure the wire so it doesn’t dangle anywhere. Use a soldering iron or an appropriate terminal to attach the wire to the cigarette lighter depending on the model of the device. Install a fuse and switch near the cigarette lighter, this will increase the safety of using this device.

Do not confuse the arrangement of the circuit details:

  • Battery.
  • Fuse.
  • Switch.
  • Relay.
  • Cigarette lighter.

Make a splitter. take a piece of wire of a suitable length, strip both ends. Then, solder the end of the long and short wires together so that they both point in the same direction. Protect the connection with a heat-shrinkable tube, then put on the connection terminal to the minus of the cigarette lighter. Position the tube so that it completely covers the contact point. Put a heat-shrinkable tube on the other end of the short wire, put on the terminal. Or use a conventional cable splitter that needs to be rigidly attached to the body.

How to mount a cigarette lighter

Before starting work, be sure to disconnect the negative terminal of the battery, and also make sure that the ignition switch is in the “off” position.

There is no single method of inserting this device, because cigarette lighters differ in length, size and shape of the case, as well as the method of attachment. The easiest way is to insert this device into a standard hole of a suitable size. If there is no such place and you could not find a suitable crown, mark the contours of the opening, then drill very thick holes with a diameter of 2-3 mm around the perimeter. After that, with side cutters, carefully cut the jumpers between the holes, then level the seat with a file. Insert the cigarette lighter to make sure the place is prepared correctly. Correct the hole if necessary.

Do not install the plug on curved or corrugated surfaces because you will not be able to secure it properly. Remember, the distance from the bottom of the cigarette lighter body to any body part must be at least 2 cm.

Having prepared the seat, proceed with the selection of the wire and fuse. The plug, directly connected to the battery, can carry currents up to 30-40 amperes without any problems, so the limitation of the load power depends on the thickness of the wire and the fuse rating. Every millimeter of stranded wire cross-section is capable of transmitting 5-10 amperes of current to the plug. If you are going to connect a 300-500 watt load, the amperage will be 25-40 amperes. The cross-section of the wire for such a current will be 4–6 mm. Attempting to pass this current through a smaller wire will cause it to melt or catch fire. Consider a path for the wire that directly connects the plug and the battery. It is advisable to lay it through the technological holes of the body next to the standard wiring.

Installation check

Check all connections carefully. The relay and splitter must be securely attached to the case. After making sure everything is in order, check if the ignition switch is turned off and connect the battery. Use a tester to measure the voltage on an unconnected battery. Place the negative terminal on the corresponding battery terminal and measure the voltage again. If it hasn’t changed, then everything is fine. If it sags by at least 0.5 volts, turn on and off all electrical appliances, including the ignition system. If the voltage does not rise, disconnect the battery and look for a short circuit. If everything is normal, turn on the switch and measure the voltage on the battery again. After making sure everything is correct, measure the voltage at the cigarette lighter contacts. If everything is in order, you have successfully completed the job.

Tools

To independently connect the cigarette lighter in the car, you will need the following tools:

  • pliers;
  • screwdriver;
  • file (you can take a file);
  • soldering iron.

Pros and cons of cigarette lighter

Its undoubted advantage is that many electrical appliances can be connected to its socket, which are so necessary on the road and make life easier: a charger for a smartphone and laptop, a recorder, a mini-electric kettle and many others.

The big drawback of the cigarette lighter is that the switching of high currents, by their design, is not highly reliable, and many modern electrical appliances, such as a laptop or a car refrigerator, have a great need for power. But the higher the current flowing through the circuit, the stronger and more reliable all connections should be. Of course, it would be nice if, in order to increase the strength of holding the plug in the cigarette lighter socket, they began to produce forks with more presser feet. But today, on most forks, only a spring-loaded contact and two mass presser feet are installed, and the central contact area in the socket is placed at different depths, sometimes very small.

During the trip, from shaking and various kinds of shocks, the reliability of the contact between the socket and the plug is disturbed. This can cause the connection to spark, short circuit or even fire. In addition, now it is becoming more and more popular to use a variety of splitters and adapters for cigarette lighters, which make it possible to connect several electrical appliances at once, and this increases the load on the network and reduces the reliability of the system.

Sequence of work

When connecting the cigarette lighter in the car, you need to adhere to a certain sequence in the work:

  • twist the nut located on the back of the cigarette lighter;
  • disassemble the device itself;
  • at the bottom of the device there should be a semiconductor plate, which often causes the cigarette lighter to stop functioning normally;
  • the plate is removed as unnecessary;
  • a protrusion is cut off on the body of the device with a file or a file;
  • after that, the cigarette lighter must be assembled;
  • the wires for connecting the cigarette lighter must be stripped 7 mm;
  • terminals are crimped on all wires;
  • disconnect the backlight wires;
  • after that, the block is extracted;
  • now you can connect wires using special connecting clips for this purpose;
  • the wires are connected like this: the first wire goes to the backlight wire. It is white-brown in color, the second and third are connected to the cigarette lighter wires (black and yellow). After that, each connection is wrapped with electrical tape;
  • wires must be pulled down and connected to the cigarette lighter socket;
  • when they are attached, you can put the cigarette lighter in place by performing the reverse sequence of operations. First, his ring is pushed, and then his glass can be installed;
  • install backlight unit.

Sometimes it may happen that the diameter of the ring does not fit the desired hole, the ring may turn out to be wider in diameter. Then you can enlarge the hole with a file or a file to a suitable diameter.

After the device is connected, you must immediately check how normally it functions.

How to listen to music through the cigarette lighter, how to connect a laptop and other devices

A cigarette lighter is a device whose direct purpose is to light a cigarette while driving. But the cigarette lighter socket, with the development of modern technologies, began to be used to connect various electrical appliances to the on-board network in the car, such as a navigator, a video recorder, a mobile phone and laptop charger, an auto compressor and many other devices. A modern person can no longer imagine himself without his car and without a means of cellular communication, and the only place to connect various devices in the car is the cigarette lighter.

Connecting a cigarette lighter

If there is no cigarette lighter, then it becomes inconvenient in the car, because any motorist knows that there is only one “socket” in the car to connect such useful and simply convenient devices on the road. If it fails, it is no longer possible to recharge a mobile, laptop, connect a navigator and do many more simple and pleasant things. Many motorists are thinking about how to connect this useful thing with their own hands and not use the services of car mechanics.

What devices are connected to the cigarette lighter?

Many drivers consider a cigarette lighter redundant in their car. Drivers who smoke use their usual lighter, but non-smokers don’t need it at all. But still, it is not for nothing that the cigarette lighter is installed even on the latest modern cars, because many of your favorite and necessary devices for a trip can be connected to its socket. Let’s look at the most popular and necessary ones that can be connected to the cigarette lighter socket.

Vacuum cleaner, because the cleanliness of your favorite machine is more important than the cleanliness of the house. Car vacuum cleaners powered by a cigarette lighter are very different, differ in power, number of attachments and appearance.

Autocompressors relieve drivers of the need to inflate tires the old fashioned way, with a pump. Along the way, an autocompressor can pump up an inflatable boat, mattress or pool. Compressors come in different capacities.

You can also connect a fan. In the heat, if there is no air conditioning, this device will help out well.

Another convenient and useful device is a heater for cars. This can be a fan heater for quick warming and defrosting of windows or a heated seat cover. They are easy to connect and easy to dismantle in the warm season.

Mobile phone. Today it is impossible to imagine a person without a cell phone, and he can be discharged at the moment when it is, well, simply vital to make a call. For this, there are a variety of phone car chargers. There are also chargers for different batteries, for example, for laptop batteries, AA, AAA batteries and others.

The adapter, if connected to the car network, will make the life of a motorist on the road much more comfortable. With its help, you can use an electric shaver, recharge your tablet, and other low-power devices. Adapters are universal and specialized.

On a long journey, a container for warming up food or, its more expensive masterpiece, a microwave oven will help out well.

Terms of use

All appliances connected to the cigarette lighter, electrical and safety rules for working with them must be observed, according to the instructions for working with electrical appliances. This means not to exceed the load (carefully read the instructions for electrical appliances).

Using a splitter, you need to add up the power of all connected devices.

The main thing to remember is that even with the engine off, electrical appliances included in the cigarette lighter continue to work and there is a risk of discharging the battery, especially if devices such as a car refrigerator or a video recorder are connected.

In the article, we examined in detail how to connect a cigarette lighter, and also found out what it is for. But if one socket is not enough for you, we suggest watching the following video, from which you will learn how to connect an additional cigarette lighter in the car:

The installed cigarette lighter should provide energy for all consumers connected to its socket through the on-board network of the vehicle for a long time and without unnecessary problems.

Laptops

Now in more detail about how you can charge your laptop from a car cigarette lighter. There are special chargers on sale designed for connecting laptops. These are adapters that convert the current from the on-board network into the voltage required by a specific computer. The principle of operation of chargers is no different from the adapters that you use at home when connected to a household outlet. When choosing a charger for a laptop, with which you can replenish the battery in your own car, you must first look at the characteristics of the computer itself. Usually, the manufacturer indicates the required voltage on the bottom panel. In most cases, the parameters are 15-25 Volts, and the current strength varies from 4 to 8 Amperes. Next, we look at the connector that is used at the output of your laptop. Different manufacturers may use slightly different connectors. Although sometimes, even within the framework of the same manufacturer, they are not identical. Honor has it that not all chargers on the market can be used specifically in your vehicle. Here you should carefully study the issue of output voltage on the cigarette lighter. When the input voltage of a laptop is from 12 to 16 Volts, and you bought a charger for a truck or truck, where the cigarette lighter has a voltage of 24 Volts, do not be surprised by the instantaneous failure of the charger. This is not a bad scenario yet. Much worse when the laptop itself burns out.

Tablets

Since tablets are often used by drivers as a navigator or purely for work or entertainment, it has to be charged at an enviable frequency. And it is extremely convenient to have a suitable charger in the car. Many people make a common mistake when using smartphone chargers in their car to recharge tablets. Modern tablet computers with powerful equipment are extremely serious devices, as close as possible to laptops. Because of this, they need more current to charge. This figure is at the level of 9 Volts and 1-2 A at the output. If you take a phone charger to the cigarette lighter and connect it to the tablet, you will almost certainly come across a burned-out controller. Therefore, under no circumstances should you use smartphone car chargers to charge your tablets. The best solution would be to buy a special charger designed specifically for tablets. Or take a modern device in the form of a Power Bank. But then you will have to additionally monitor the charging of the portable battery. That is, in many cases, connecting to the on-board power supply is more convenient.

Phones and smartphones

Before discussing a laptop specifically, it is worth talking about a device for charging phones and smartphones in a car. Connecting a gadget to them and replenishing the battery of the device will not be difficult. Fast and safe charging of a smartphone requires a voltage of about 5 volts with a current of at least 0.5 amperes. But it will be better if you take a device with 1 Ampere. When buying a charger, look at the Output label. At the exit, such a designation must be present without fail. Such devices serve as long as possible, and completely protect the smartphone from possible breakdown. Structurally, telephone chargers for the car are somewhat different from each other. Basically, motorists can find 2 options.

  • Charging in the form of one cable, one end of which goes to the cigarette lighter, and the other connects to a phone of a certain model. Currently, the release of such adapters has been discontinued because they lack versatility. Only for Apple products there is a universal connector that allows you to charge your devices from the car’s on-board network with one cable: iPhone, iPad, iPod, etc.
  • Universal chargers for the cigarette lighter with standard ports. Modern and practical devices with several connectors on one body at the same time. Different amperage is directed under them. One connector can supply 1 Ampere, the other 2 A or more. If you take such a charge, you can simultaneously charge several different gadgets.

The difference for and for 700 rubles. When buying a charger, be sure to study the voltage readings on the adapter and your phone. The voltage of the charger should not exceed the voltage on the phone by more than 5%.

Charging methods

Since the driver needs to always have at his disposal charged gadgets, special devices should be foreseen for the car in advance to replenish the charge of various devices. In total, there are several options for how you can charge laptops in the car.

  • Adapters for 12V. These are special adapters designed to work on 12V. Since the laptop is adapted for charging via a 220V household network, direct connection is impossible. Using an adapter, it is inserted into the cigarette lighter and then connected to a laptop, smartphone or tablet. Such adapters are often universal and have outputs for different equipment. At the same time, it is possible to get an impressive amount of energy. They work only when the ignition is on or the engine is running. At its core, it is an inverter that converts the electrical energy of a car. One side connects to the cigarette lighter, and the other has a special outlet. This is often USB, but other options are possible. Convenient in operation, compact and versatile. Suitable for laptop, smartphone and tablet. On average, they cost from 1,500 to 6 thousand rubles.
  • Charging device. There are special universal chargers designed specifically for laptops. They are divided into model and universal, that is, they are suitable for a wide range of models, or can be used only for a specific laptop. If you buy a charger, choose one from the same company as your computer. Although not all laptop manufacturers make car chargers. To be able to charge different models of laptop computers, an appropriate adapter is required. The chargers are very easy to use. Average
  • Standalone ROMs. These are starting-chargers that are compact in size and in many ways resemble modern power banks for smartphones. The ROM needs to be charged, after which, using adapters, they transfer the charge to the gadget. To charge your laptop, you first need to charge the device itself. And this is not always convenient. Modern models can maintain a charge of devices for 3 hours. But not suitable for frequent use. When the charger is discharged, it needs to be charged by itself. And stand-alone starting-chargers cost about 6-10 thousand rubles.

Each of the options has every right to exist. What exactly to opt for, the motorist must decide for himself. It will be great if you can find a charger specifically for your laptop, designed to connect to the car’s on-board power supply. But if it is not there, universal chargers, adapters and ROMs will do.

Criterias of choice

When choosing a charger, many doubt whether it can be used in a car, and whether the use of such charging will lead to a short circuit in the car’s electrical network. After all, supposedly power supply to a laptop or other gadget will go differently than when charging through a household outlet. Such a fear is justified only if the connection was carried out directly from the laptop to the cigarette lighter. You should understand how to properly connect the laptop to the car through the cigarette lighter. There is no direct connection here. Since the charger has an adapter-like intermediate element, there will be no short circuit problems. The main thing here is to choose a really good device that will fit your laptop, smartphone or tablet.

  • Computer settings. To get started, study the specifications of your laptop to understand which adapter will be able to meet its power needs. If you choose the wrong charging, it can overload the power supply, or it can pass too little energy. As a result, the charging process will take more than one hour.
  • Connectors on the laptop. The USB port is the same on all modern computers. But the charger socket, depending on the manufacturer of the gadget, may differ. Therefore, choose an option that will be compatible with the plug connector.
  • Manufacturer. The ideal option is a car charger from the same manufacturer that released the laptop itself. In some cases, they are found in a complete set of charging for an automobile and ordinary household power supply. But not all companies have such adapters. Trust trusted component manufacturers, as cheap Chinese chargers can burn your laptop and cause a short circuit in the car’s network.
  • Price. Too cheap models will not last long. To begin with, there is no guarantee that the stated specifications are true. This is often the fault of manufacturers from China. Choose something from the middle price segment. If possible, buy a high-quality expensive charger from leading manufacturers.

When choosing a charger, you should decide in advance what kind of gadget it is intended for. There are certain differences in this component that make you pay more attention to the purchase of adapters for phones, tablets and laptops.

Useful Tips

There are a couple more points that you should definitely pay attention to when choosing a charger.

  • Wires and their fastening. Choose chargers that have strong, elastic, but tough enough wires. It is also extremely important to have a special sealed protection in the area where the wire and the connector are connected. If there is no protection, problems will begin from this place. The wires will break, so the charger will need to be replaced soon.
  • Length of cable. The location of the cigarette lighter differs from car to car. Check in advance if the charging wire is too short. It is recommended to choose charger models equipped with a long cable. So the driver will be able to correct it and put the gadget to charge where it is convenient, and not where the cord is enough.
  • Short circuit protection. Really good chargers have the added function of short-circuit protection. With sudden power surges, they automatically turn off and stop supplying energy to the gadget being charged. This prevents damage to laptops, as well as avoids problems with the electrical network of the machine.

Having decided on the main characteristics and requirements, you can choose a device at your discretion. Design, size, presence of indicators already play an aesthetic role, that is, they do not affect the parameters and performance of the device. Charging in a car is really a convenient thing for a modern person. It allows you to charge the gadget, if necessary, and not frantically search for an outlet in the nearest cafes, not go home or stay late at work. It is only important to choose a device that matches the parameters of your laptop, tablet or smartphone, as well as satisfies the capabilities of the car’s on-board electrical network.
