It is very likely that you have heard of external batteries so, if you find yourself in a hurry with your smartphone, you can charge it anywhere. A very useful accessory whether you are going on a trip, on a field trip or even if you have to leave home quickly and you do not have time to charge your phone. But of course, what if what you need is to charge your PC? Today we tell you everything you need to know about external batteries for laptops , as well as showing you a compilation of the best options on the current market.
How to choose an external battery for your computer
The first and most important thing to keep in mind is that not just any Power Bank will help you charge your laptop correctly. There are a number of important parameters that you should know about both devices before opting for an external battery of this type.
The aspects that you should take into account are the following:
- Type of connector : a fundamental aspect is the type of connector to the current that your laptop has. The most powerful teams have mostly the USB-C or Thunderbolt standard . However, if your laptop is a bit older, it probably has the circular DC connector . Therefore, when choosing an external battery we must consider the type of ports it has, which can vary between: PD (USB-C), DC (circular connector) that can be input or output, or directly an AC connector to plug in the laptop’s own charger.
- Supplied voltage : the electrical voltage with which your equipment works is also a characteristic that you should know if you do not want to damage it. This parameter is measured in volts (V) and you will normally find it in your equipment’s own charger. Therefore, you need one of the output voltages of the Power Bank that you decide to purchase to correspond to the input of your computer.
- Power supplied : surely this feature is one of the most familiar to you when buying external batteries. It is measured in watts (W) and represents the electrical power or, in other words, how fast your battery will charge . If you want to know the minimum value that your computer needs to continue charging even at full capacity, you only have to multiply the value of the voltage by that of the electrical intensity. That is, multiply the volts (V) by the amps (A) . In the example label that you can see a little above, that computer would need a power of 10.71 W. If the Power Bank you choose has a lower power, it will simply cost you to charge the battery of your equipment as you are using it .
- Capacity : Finally, it is also important that you choose the appropriate capacity based on your needs. This parameter is measured in milliamp hours (mAh) and gives you an idea of the number of times you will be able to charge your computer’s battery. If you are going to be away for several days and you are not going to be able to use a “normal” power source, we recommend that the battery you buy has a high capacity, such as 25,000 mAh.
