1. Capacity of the Portable chargers

Capacity of the portable power bank says about the deliverable amount of power that a power bank can retain rather sustain within itself. Most of the best power banks tend to have capacity around 10000 mAh. But we should be keeping it in mind a 10000 mAh power bank can not reproduce whole of its power while charging due to conversion loss. Thus the delivered outcome is always less than 10000 mAh. Precisely the average efficiency of power banks is found around 75%.
