How to Buy Portable Power Bank

Capacity of the portable power bank: Capacity, as can be easily presumed, is used to determine the amount of charge the portable power bank can retain within itself and can deliver at the time of need. It is measured in mAh unit. The more the measure, the more is the ability of the portable charger to charge up your android smartphone.
