If you want your mobile not to run out of battery, a good option is to have an external battery. There is many different external batteries, and with some of them it is even possible to charge a laptop battery. However, is it possible to charge your laptop battery with any external battery?
Can you charge the battery of your laptop with the external battery of the mobile?
Charging your laptop battery with an external battery is not impossible. However, only with some external batteries it is possible to charge the laptop battery. Keep in mind that currently it is only possible to charge the laptop battery when they have a USB Type-C to charge. This is the case of MacBook, for example. However, for all other computers, it is not possible to charge the battery using an external battery. Basically, this is the case because the voltage required to charge a laptop battery is around 19 V, and external batteries usually have a voltage of around 5 V. It is possible to buy an adapter with which to convert the voltage of the external battery at 19V, but the capacity of the external battery will be consumed in no time, so it is not something really useful.
Still, if you have a laptop with a port USB Type-CDo not think that buying a 19V compatible external battery is really useful, because it is not the case. When charging the laptop battery at 19 V, the power consumption will be very high, and a battery that could generally be useful for charging a smartphone two or three times, will only be useful for charging a small percentage of a smartphone’s battery. laptop. So in general, it will not be useful at all to buy one of these batteries that are also compatible to charge a laptop battery.
In addition, these batteries are usually expensive, and that difference in price is better spent on buying an external battery for our higher quality smartphone.
