BEST POWER BANKS OF 2020: Power Banks, 10000mAh Power Banks, 20000 mAh Power Banks, Cheap Power Bank

Updated: May 13

Portable power banks are necessities when traveling since electric devices like phones, tablets, computers, and cameras may run out of power at any time. Efficient power banks may save time and even make life easier and travel smoother.

Below are some power bank buying tips.

Users need to consider the design and capacity of a power bank. As for design, size and weight are the primary features which should be considered. As is usually the case, the higher the capacity of the power bank, the heavier and bigger it may be. However, some power banks, being compact, still have high capacity.

Most portable chargers, being small, have a capacity of around 3000mAh, however, they may run at 65% efficiency which may not be able to charge the phone once.

Power banks with a capacity of 6,000- and 7,000mAh, small and light, are able to fit in a pocket and supply two or three charges for the phone. And a compact 10,000mAh model is capable to do to the same job.

Power banks of 15,000mAh and above will be heavy, however, power banks with a capacity higher than 27,000mAh (100Wh) cannot be taken on the airplane without the airline’s approval.
