    Although this had fairly good ratings, I read all the bad reviews too about how it wouldn't charge their phone and decided I would try it for myself. After I opened it up, charged the mophe completely and tried to charge my phone but it wouldn't charge. Returned it. Not sure why this particular cheap one does this but maybe the more expensive mophe ones are more reliable. I gave it two stars because it looks nice and sleek
