Directly from the battery

The laptop can be charged directly from the battery if the rated voltage of the laptop battery is also 12 V. Otherwise you can not do without transforming electricity. You can make such devices yourself only if there is experience and relevant knowledge.

An inexpensive option for changing direct current voltage is the use of small boards of adjustable DC. DC converters, with which you can easily raise the battery voltage to the required values.

Another method of charging a laptop from a battery is the use of a voltage converter. That is, if you manage to independently assemble an inverter, at the output of which there will be a variable voltage of 220 V, then you can load a laptop using a conventional network adapter without any restrictions.

This is an extremely dubious method and it is not recommended to use it, since it will be very difficult to give the correct value of the current strength (a) and voltage (c).

How quickly charging is carried out

On average, the charging from the rolling lasts about 3 hours, but if the capacity of the laptop battery is too large, then it may pass for a lot of time before the battery charge is completely restored. When using modern laptopes, this indicator does not matter much, because during charging the battery can be used in normal mode.

In addition, the recovery of the battery charge can be thus can be carried out during movement or in the room not equipped with electric sockets. Charging the laptop through Power Bank will be successfully made only if the external battery itself has a fairly high level of accumulation of electric current.

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

Small guide

Before we move directly to the list, it is important to clarify several details regarding the charging of laptops using PowerBank.

Can a laptop with PowerBank?

A portable external battery equipped with a USB-C Power Delivery (PD) port is able to charge a laptop. We waited for this moment for a long time, and it finally came, and all thanks to USB Type-C and the USB Power Delivery standard.

Manufacturers are already setting a port of this type in many laptops and smartphones based on Android. Iphone. So far the only flagship that has not switched to a new connector (it still uses Lightning).

Now many laptops are delivered with USB-C charging devices, which provide faster charging a computer (mainly with a voltage of 60 watts and up to 100 watts).

However, most laptops can also be charged from external batteries with a voltage of 30 W. This, of course, is slow, but it works.

Ideally, for charging laptops, you need to use the USB-C-USB-C cable (USB-C connector must be installed at both ends).

For a full charge, you will need PowerBank with the same or higher output power as the charger of the laptop.

Can a jet with a capacity of 20,000 mAh charge a laptop?

Powerbank with a capacity of 20,000 mAh is able to charge a laptop once or several times. However, at the same time, it should have a USB-C connector, because standard USB-A cannot provide enough voltage for charging a laptop. That is why most laptops for laptops have a USB-C PD port.

Ideally, you will need a powerful external battery with a USB-C with a 30 W output or higher output. This should be enough to power any ultrabook, since most of them are supplied with power adapters at 30, 45 and 60 watts.

How effective such charging is?

So, as we found out to charge a laptop from Power Bank. But no less relevant is the question of how effective such charging is. And does it harm the battery to the battery? Let’s just say that the voltage used in advanced portable batteries (19 volts) is exactly the same as when replenishing the laptop battery using a regular charge. This means that there will be no harm in this regard. The only thing that can fail is the charge speed. Not all portable batteries provide sufficient current strength. It is possible that with a current force of 2 amperes, the laptop will be charged much more slowly than when using the standard charging adapter. However, you need to sacrifice something. Everything is impossible to get at once. Nevertheless, the effect of charging by Powerbank is pretty good. You can charge the laptop at any time and anywhere.
