Despite the large capacity of the battery is quite compact and well stowed. Design Technically I think he's also absolutely great. Amzdeal is one of the few suppliers in the market, which also offer white batteries that therefore ideally suit white phones and tablets.
The battery has 2 outputs: 1 output has 1A charging current and the second has 2.1A. These two currents to mobile phones can be perfectly load (1A) as well as tablets with larger battery (2.1A). Pressing the round button and the current battery level is (25% / 50% / 75% / 1000) displayed on 4 blue LEDs. I find this very handy, because one is always informed about the current battery level.
The battery is charged via a standard micro-USB cable, which is also attached (white in color). Turned around this cable can of course also for charging the mobile phones / tablets, etc. use.
I get with this battery my S3 loaded more than 4 times loose, one is much less dependent on the socket with this battery. The build quality looks good. Since even the right price / performance ratio, I give full stars.
