Battery and capacity about power bank Battery There are two main battery type Lithium Ion and Lithium Polymer Lithium Polymer is the new advanced battery is made of aluminium plastic casing and has lighter weight and better performance and safety features , though a bit expensive. On the other hand Lithium ion ( 18650 Lithium Battery) which means length is 65 mm and diameter of 18 mm is cylindrical in shape is older generation but still popular due to lower price. So it’s preferable to go for Lithium Polymer batteries instead of lithium ion as they are safe, more lightweight and better quality . even if it means spending few more rupees Capacity The capacity mentioned on the product is in terms of mAH is not a real indication of the actual usage capacity. Generally one has to factor the leakage and voltage conversion. So one can safely assume that the actual available power would be 20-30% of the mentioned mAH. So a 5600 may battery would have a usable capacity of 4400 mAH. This should be the base against which you should calculate your requirements witkeypowerbank
