Can you charge a Laptop with a USB Powerbank?!

How fast is charging

On average, charging from a power bank takes 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 replenished. 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 must 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 a 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 to raise the voltage from 3.7 to 19 volts using a special converter. 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.

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 the laptop is not connected 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 the battery charge in advance.

What to look for when choosing

When buying a new power bank, you need to choose a model designed for charging laptops. Phone devices are not suitable for this purpose. Next, you should 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 about 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 also matters in this case, because in the event of an emergency power outage, several devices may need to be charged 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.

To charge the laptop, use the Thunderbolt 3 connector, USB-C (depending on the model), which is located on the lower side of the device, and a charging set (included).

The process is simple: insert one end of the cord into the desired connector on the laptop → the second into the power adapter → plug it into a power outlet.

For information: the company does not use the MagSafe connector in new models.

There are alternative ways to charge your MacBook, for example, if there is no charging. You can learn about this in the following sections. But first, a few tips for properly recharging portable gadgets.

General recommendations

What you can / cannot do when charging a Mac (for example, this MPXQ2UA / A):

From general recommendations on how to charge a MacBook battery, this MQD32UA / A or another, it’s time to move on to proprietary tips from the manufacturer of portable technology itself.

possible, charge, laptop, power

External battery from another manufacturer

There is another option. BatteryBox (not a branded accessory). It looks like a small box, inside is a battery, outside is a cable. How do I charge my MacBook with an external battery? Very simple. The BatteryBox connects to the laptop like a regular powerbank, i.e. the free end of the cord plugs into the charging port on your Mac. BatteryBox will be able to extend the battery life of laptops, for example, from the Air series ≈ by 12 hours, Pro. ≈ 6 hours.

When to charge

You can charge the device with any amount of charge, at least 20%, at least 50%. Just do not forget about the cyclicity of Li-pol. The more often you recharge the laptop, the more days it will take to complete 1 recharge cycle.

Charge from another Mac

There is an option, how to charge the MacBook without “native” charging. Just use an adapter and cable from another Mac (for example, ask a friend or neighbor). It is worth with Honor that the power of different models is different, for example, for a 13-inch one needs a 61-watt charger or a 15 “- 87 watts. Low power charging won’t power up a Mac with more watts.

Is it possible to constantly keep the MacBook on charge, often “recharge” the gadget

The laptop can be used connected to the network (all day or several hours. no difference). Apple took care of the safety of its devices and equipped them with a controller that, after reaching a full charge, “cuts off” the supply of current to the battery. But Mac, for example, MREE2UA / A, is still a portable device, so it makes no sense to keep it on recharging around the clock.

How to properly charge your Mac when transporting or storing

If you have a long journey, it is worth replenishing the portable gadget’s energy supply by 100%. This is exactly what the manufacturer does when delivering poppies from factories to points of sale.
