Type of Battery

There are two main battery types; Lithium Ion and Lithium Polymer.
Lithium Polymer is the new advanced form of a battery, made of aluminum plastic casing. A little expensive as compared to lithium ion, it is lighter in weight, and has better safety features and performance. On the other hand Lithium ion, ( 18650 Lithium Battery) which is 65 mm in length with a diameter of 18 mm, is cylindrical in shape and, despite being old school is still popular due to its low price. The efficiency of a power bank can be measured by its capacity to provide multiple charges to your device.

Capacity – Bigger is always better

The capacity mentioned on the product is in terms of mAh which is not a real indication of the actual usage capacity. Generally, one has to factor in the leakage and voltage conversion. The actual available power would be 20-30% of the indicated mAH. So a 5600mAh battery would have a usable capacity of 4400mAH. This is the basis against which requirements must be calculated So bigger is always better but portability should also be kept in mind while buying a power bank.
