They have become essential accessories. The external batteries or power banks They are devices that have solved the lives of many users, since taking into account the intensive use that we give to social networks today, the cell phone battery runs out when you least expect it. The solution? Always carry one of these life preservers.
What should be considered when buying an external battery?
It is external batteries they have a single function, and it is none other than to power other devices. Some manufacturers have included extra features such as an LED flashlight, but keep in mind that these additions obviously reduce battery life.
If the only thing that interests you is being able to charge your cell phone as many times as you can, you only have to look at two details: the battery capacity and the charging speed. Batteries with USB-C ports are the ones that offer the best performance, since the new communication port allows for much more powerful energy transfers, thus charging your device faster. In any case, the normal thing among the cheapest models is to find traditional USB-A ports with fast charging.
As for the battery capacity, 10,000 mAh is a reasonable amount with which to get at least 3 charges on a cell phone, but you can find models with more capacity reaching 30,000 mAh. The problem with this is that the more mAh it offers, the larger the volume of the battery will be, and it will end up being a problem to always transport it with us.
The best-selling version of the popular ADATA brand is the APT100, an external battery available in a large number of different colors. It has 10,000 mAh and four status LEDs to instantly check the remaining capacity that we have left. It incorporates two USB-A and is the cheapest battery you can buy from the brand.
A model that stands out for its small size. It has a 10,000 mAh capacity and seeks to offer a compact and portable solution for those who want to always carry an emergency battery with them.
Model of 10,000 mAh quite thin that has a USB-C port, although strangely it is only input (to charge the battery quickly). It has a small LCD screen to know the remaining capacity.
Same model as the previous one, with the difference of offering a capacity of 20,000 mAh. With this capacity you could charge an iPhone 12 5 times, but of course, it weighs much more.
A powerful Power Bank of 30,000 mAh with port USB-C able to offer 20W of power with which to recharge devices at maximum speed. It is a very powerful model that will allow you to fully charge an iPhone 12 a total of 7 times. Its only drawback is obviously the size and weight of the product (690 grams).
