I can even charge my iPhone so

The shape of the charger is really nice handy, but it is only in the form of lipstick, not even in Lippentstiftgröße if someone takes this description literally and such a small device searches. The material of the device is very stable and high quality. A storage case and a comprehensive manual available.

Very practical is the device for owners of newer Apple devices. With the additional built-in Apple Lightning adapter they can be charged wirelessly. Other devices can be charged with a USB cable (also simultaneously).

The power indicator Personally I like not so good. This is certainly a matter of taste, but I feel confusing as too vague and unnecessary: ​​When both LED lights, there is a charge 50-100%, only one LED is still a charge of 10 to 50% available and 10 to 0% will flash then both LEDs. An LED indicator of z. B. 4 beams that date back just equally, I would find more manageable.

To the capacity of fully charged PowerTube following may be said: my iPhone 4s I can about exactly once so full charge. For sometimes necessary charges the device is safe suitable. Who needs more and more cargo, but should perhaps equal to buy a more powerful machine, but before he sits without power on dry land. My daughter has an almost equally large device from another manufacturer with approximately twice the capacity at a lower cost. For only a boot I find this device quite expensive.
