What is Battery capacity maximum?

A power bank's capacity is measured in milliampere hours, and the largest figure in a range tells you the ceiling for that brand. More capacity means more charges for a phone or a top up for a laptop, and it also means a larger, heavier brick to carry. Allpowers reaches 31,000 mAh, the highest in this group, with Anker behind at 27,000 mAh. Akkuk.hu offers 25,000 mAh, ALLPOWERS offers 24,000 mAh and MPOW offers 10,000 mAh.
