This external battery charger is in use since Christmas and maintains fully what it promises. It was charged, so you could try it right. I have read reviews for many days to get a decent unit as a Christmas present. It is super convenient because it fits loosely in the pocket and includes a protective sachet from scratches. Contained no pure charging cable, is probably standard, but of EasyAcc you have the appropriate rapid charging cable ordered Rip-Rip to. Anchor I have seen only charging cable that also transmit data, which charging can be slower. Anyway, it can be perfectly and quickly two smartphones (1x 3000 mAh and 1290 mAh 1x) simultaneously charge and then it is still almost full. (The battery has the gift to match the 3000 mAh smartphone, which you can 5x charging with the charger should be.) As smartphones rapidly have an empty battery pack these days, especially if you're traveling constantly playing any games, it is worthwhile in any case, to lead for emergencies such an external charger with you! Even at work you may indeed rare times use the socket, but the charger no longer need that too. It's also nice that it is simply not turn on by itself by shaking (as with other devices) or sensitive buttons during transport. The design is impressive and the warning lights are also incredibly convenient.
Attention, better recharge overnight. According much power needs 6 to 8 hours to get back to be fully there!
Not to mention the excellent value for money! Strong buy recommendation!
