Hello. I bought this super product of Easyacc and must say I'm thrilled! The PowerBank is really at this price the hit! It costs only 19.99 and in addition it is very nice. The design I like very much, because it is simply well designed, unlike other. It is scratch-resistant and bumps do not occur, it's not too easy nor too difficult. So you can easily charge the batteries on the go, without wasting a lot of space, because the powerbank fit into any pants or jacket pocket. The blue LED shows exactly what percentage battery you still have, even with just 2 LEDs you can safely order to go out, as this all is enough for a cell phone. It is a top product as the price and the quality are very good and it does what it should, even beyond, it is very nice and you can, among other things at school or at work brag nice if the other juice emanates. All in all: strong buy recommendation from me and full star! Super, weiter so EasyAcc! Mfg John
