This product looks very heavy and it's not compact. power back is not bad. but charging is very slow. it takes more time to charge. mainly it's not charging fats I don't know about others who bought this. but absolutely I feel ambrane is the best because I have used ambrane before it charges very fast.
Awasommm product , I'm using it from last week. It's a must buy who travel a lot and can't live without Internet. BSC when you use 4g your phone battery will discharge very fast . This 20000mah power bank doing its job perfectly . I have 3mobile and yes this power bank charge mi note for 4/5times . Must buy it
