Modern laptops can run 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, this feature may not be available, so each owner of a laptop should take care of alternative ways to restore battery power in advance.

Is it possible to charge a laptop from Power Bank
The easiest way to restore the battery capacity of a laptop without using a charger is to connect an external battery. This product has the following advantages:
- Large capacity.
- Compact size.
- Light weight.
- High reliability.
Despite the fact that the cost of such products is not a low cost from the inability to continue working on a laptop computer, they can be much higher. Particularly important is the smooth operation of the laptop for freelancers, whose work is fully carried out remotely.
The capacity of such a product is sufficient to maintain the laptop’s operability in working condition for a day or more, so during this time you can replace the charger or repair it.
Its compact size and light weight are especially important when traveling. Using these devices, you can charge your laptop outdoors or in a hotel room. When traveling abroad, the bank will avoid the need to purchase adapters for electrical outlets.
High reliability and a long service life will allow you to use the device for a long time, and low self-discharge - always have at hand a fully charged and ready-for-use backup power source.
Why it is impossible to charge a laptop from a telephone
When buying a Power Bank for a laptop, you should pay attention to the designation on the package and label. Similar products are available for charging mobile phones, so you can easily confuse and purchase an unsuitable device for use. You can’t charge a laptop by using a power bank from a phone, because the voltage at the output 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 increase the voltage from 3.7 to 19 Volts. For such a connection, you need to connect the output contacts of the power bank with a converter, which then should be correctly connected to the laptop socket. Of course, this is worth doing, it is better to immediately get a normal external battery.
How fast is charging
On average, charging from a power bank lasts about 3 hours, but if the capacity of the laptop’s battery is too large, it can take a long time before the battery is fully restored. When using modern laptops, this figure does not matter much, because while charging the battery, the device can be used in normal mode.
In addition, the restoration of the battery charge in this way can be carried out during movement or in a room not equipped with electrical outlets. Notebook charging via Power Bank will be successfully completed 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 is insufficient to connect consumers to it, you must regularly connect it to a special adapter or purchase a device with a solar battery.
What to look for when choosing
When buying a new bank you need to choose a model designed to charge laptops. Phone devices are not suitable for this purpose. Next, you should pay attention to the following characteristics:
Capacity. The number of laptop battery recharges without connecting a power bank to the network depends on this parameter. 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.
Number and type of ports. If it is possible to charge not only a laptop, but also a phone from Power Bank, then it is enough to purchase one powerful device to charge all devices running on lithium batteries if necessary. The number of ports is also important in this case, because in case of an emergency power outage, several devices may need to be charged simultaneously.
Weight and dimensions. If you often have to take a power bank with you, but there is no need for a large capacity of the product, then it is enough to purchase a device with minimal capacitive characteristics. Weight and dimensions are always in direct proportion to these parameters.
Body material. The body of the product should not only be shockproof, but also protected from moisture and dust. Only in this case, you can use it in long trips and camping trips without fearing for the safety of the device.
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 companies that value their reputation, will work out the recommended operating life of the manufacturer without any serious deviations in performance.
To buy such a product, you should contact only a trusted and well-established trading organization, otherwise you can easily run into a fake.
Power Bank is a functional device that will replace a standard adapter. In addition, some models can be equipped with a flashlight, as well as an output for connecting car gadgets, which allows not to use the battery while the car is parked.
