hey, can i know how do u check whether the power bank is genuine or not ? i recently broke my yoobao 651, 13000mah. in the next hour, i send it for warranty. however they just gave me a brand new power bank itself(without boxes and everything). so can i know how to identify fake yoo bao 651 power bank ??? what suspect me is, the charging led goes from left to right. previous one wheni bought goes from left to right....
