Super device, very satisfied!

This is a simple but high-quality finish Power Bank. Supplied with a USB cable is included. This one invites to the Power Bank. The same cable can again be used to charge devices with a micro USB input, for example, all Galaxy devices.
The capacity is sufficient for about 2 mobile phone charges, depending on your phone type. I think that's sufficient. In return, the bank is also very compact (like a cigarette). If you want to charge tablets, the handle is recommended to more powerful Power Banks, I own for this purpose a second, also by RAV Power.
Is great and unique that you get displayed by pressing a button, how much more cargo capacity is available. This is indicated with blue LEDs. So you can check quickly after long periods of disuse, if you still need to charge the bank or not.
I find the device super and would buy it again at any time.
