Hay this power bank gifted me someone and I used and found that this is really not good to carry becouse it' s very heavy power bank.we can' t keep it in pocket becouse it was in squire degine.and battery backup in not too.much comparing to other power banks.also battery life is not too good becouse we can charge only twice after full charging it.design is also very weird becouse we can' t keep it in hand or pocket so no value of money guys only wastage of money.so don' t go through to buy this power bank.
