How to choose power bank battery

The cell is the most important part of the mobile power supply. The quality of the cell basically represents the quality of the mobile power supply product.So this is the first choice. Rechargeable lithium ion batteries have the several on the market. Polymer batteries, batteries, aluminum shell, batteries, steel shell cylindrical metal case batteries (the most commonly used is 18650 cylindrical batteries).

Aluminum batteries are mainly used for mobile phone batteries.Bbatteries steel shell is too low-level basic need not, is mainly used as mobile power polymer batteries and cylindrical batteries, relatively speaking. Cylindrical cell price cost is lower, but the performance of polymer cell will be better, capacity and discharge platform and cycle times are better than cylindrical type, the most important is that the safety of polymer cell is significantly better than cylindrical cell, polymer cell is aluminum plastic film shell, no matter what the case will not explode, The cylindrical cell is a metal shell once abnormal charging and discharging may explode, causing physical injury to the user. Like exploding cell phone batteries, there is no way to prevent it, only to reduce the probability of it happening.

Therefore, the best choice of mobile power supply polymer cell. There is no need to take a mobile power supply to risk the explosion.
