I have the battery pack now since a few weeks in operation and I am completely satisfied. I invite not only my phone and my tablet when I want to be independent from the power supply / needs, but I also run my WLAN stick with it. The integrated LED flashlight you do not necessarily have, but when it is at it, also good. However, one should not expect too much from the LED lamp. It's just an LED that lights up. The term flashlight is perhaps somewhat exaggerated. But for me no reason to devalue the PowerPack.
