I ordered this external battery I received on time. He is a very nice product. On arriving, there is still 75% battery, I tried to load my nexus5 + ipad mini no problem, by cons when I wanted to recharge himself, he was stuck at 30% (I spent more from 12am to recharge this battery), so I tried to unload (charge my Nexus 5 + lumia 1020) draws recharge, but this time is even worse, it is now stuck at 10%. Thank you to Anker with customer service contact me to solve this problem.
