I think the most reliable one are either pineng and yoobao, i personally had use both and both are good, but im more inclined towards pineng powerbank because it has digital battery indicator, so u know how many power left in there rather than the normal plain indicator. Btw the pineng powerbank is original, any of you guys interested can check my sig.
