But in fact you DON'T need a 3.7V charger. ... So you can charge your 3.7V battery pack with the 5V charger, but be careful, choose one with the automatic circuit, just like the EasyAcc Power Bank. It is equipped with multi-protection, just like over voltage protection, short circuit protection and so on.Jul 28, 2016
