Today I ‘d like to share with you some information about How to choose power bank.The first thing is you need to know what size battery pack do you need? Small or big? Then you can determine a range.
Second, you should consider the the output at which it can charge your device. This is something to keep in mind when you are shopping around. You should ask yourself what you will want to charge. Most of the smaller power banks (2,000-3,000 mAh) will have an output of 1A since they don’t have enough to charge a large device. Once you move into the next tier, a 2.1 or 2.4A output starts to become the standard.
Last but not least, what mAh capacity do you looking for? Here are some mAh for your reference:
