POWER BANK why would explode ?

POWER BANK why would explode ?

For POWER BANK composition, has two parts , one is the circuit board , one is batteries .

Section on batteries , the part of the battery manufacturers do not have the ability to self-production of batteries , so you need to buy the external batteries .
This time inferior cheap “junk batteries” poured into the market , the so-called “junk batteries ” is actually purchasing waste batteries . This battery has been used , and has been aging , if the frequent use , it will generate heat , in the heat of the environment, the expansion coefficient of the battery will increase, this time it is possible to produce an explosion.
Therefore, when choosing custom power bank, respect for the batteries need special attention.

Witkey POWER BANK has four heavy security protection: thermal protection , overcurrent protection, overvoltage protection, short-circuit proof .
witkey POWER BANK has obtained a number of patents to ensure that Class A quality , exclusive ” proof helmet” patented technology, the security level to achieve five-star eliminate explosion hazards, providing quality protection for mobile power products.
