Small practical power plant, but ...

Well, my wife does not want to publish the mobile battery. He is now always loaded into your handbag so that the mobile service is not empty. That's saying something, because it is not very technology-savvy.

But the device included in itself, which a 20cm long USB A to Micro USB cable for charging. Also with any other arbitrary Mirco-USB cable can charge the device.

Did it sometimes on my Samsung Galaxy Note 3 tried. With such a "strong" smartphone that requires a little more juice, you have to remove the battery at 100% the same as it recharges continuously and then idles.

A looping is not possible to say a simultaneous charging of mobile batteries and the charging of a terminal. Either recharge or discharge.

The Scheckkkarten format does not quite fit, a little thicker and larger the battery charger is already.

But, what to do in no case, for example, to load a smart phone and use it simultaneously. This battery is overwhelmed and hot, really hot.

Who needs a mobile battery charger and lightweight examined with enough juice to give him a chance.
