If you are often outside (and even at home), you have surely noticed how quickly your phone, tablet, or other electronic device discharges quickly. For this, some opt for universal external batteries, allowing them to charge their devices anywhere and anytime. This could be your case, but you may not know which one to choose. We will help you.
How to choose your external battery? There are of course all sizes, colors and shapes, and it is even possible to opt for a personalized external battery for example. But that is not the question. To choose well, you must above all focus on capacity .
The capacity of a rechargeable battery is usually measured in milliampere-hours (mAh). For example, an iPhone 11 comes with a 3110 mAh battery, while the Galaxy S10 relies on a 3400 mAh cell.
It therefore goes without saying that any portable battery you are thinking of acquiring must have at least as much capacity as the device(s) you wish to recharge with. In this way, you can fully recharge it(ies) from a fully discharged state.
Now let's say you also have a Galaxy Tab. This tablet has a powerful 7300 mAh battery. Assuming you want to be able to charge both devices with the same external battery, you would need to choose one with at least 10,000 mAh.
If you are unsure of the battery capacity of your phone, laptop, tablet or other, you can find out on the manufacturer's website, in the technical section.
You can also try entering your device name on google followed by "battery mAh". So, for example, to find out the battery capacity of the iPhone X, just search for "iPhone X battery mAh".

To sum up:before spending money on a power bank, we strongly advise you to check the capacity of the batteries concerned and make sure you choose one that can support (in every sense of the word) your equipment. existing mobile.
