Never again "My battery is dead!"

The metal housing (aviation aluminum dish) is stable and well finished. That makes then also quite proud weight (230 g without casing and cable) noticeable. It also looks very chic in the noble optics. For this, a velvety, gray envelope is included for safe transport, so no unsightly scratches can arise and the Power Bank looks long so great.

The Power Bank has a charge level indicator 4 LED for each 25% and an on / off switch. In addition, a charging cable with four different connector types for different products is. It has 2 USB outputs (5V / 1A and 5V / 2.1A). The Power Bank is charged via USB or an AC adapter. This takes about 8-10 hours. The then but enough energy to recharge a smartphone such as about five times to. Very handy on the go! For me, it is often the case that the battery is empty the phone whenever I have to go urgently. Of course, then even the eBook reader, I like this have also empty. With the Power Bank me is the matter now, because I can both devices on the go at any time to charge.

The Power Bank turns off automatically when it is fully charged or completely a few seconds after power loss occurs. I find that very helpful and useful!

In addition, the battery has a protection against overtemperature, overcurrent, short circuit, explosion and overvoltage. That and the CE Mark are very important to me.

The manual (with German part) focussed on the essentials, however, is poorly translated. This can be seen already in the product description.

Unfortunately, no mains plug is included in delivery, so you similar to the mobile phone / smartphone must have recourse.

The lifetime warranty is of course a further advantage.

Overall, in spite of small criticisms five stars because I find the battery great services!
