Power to go - the second

Searched a flexible power expansion for my Samsung S3. When navigating the Smartphone of the built-in battery made more quickly tired.
My choice was the above Powerbar. My current forecast is very ambivalent.
I can Freshly charged the smartphone once vollstädig load. But unlike my other Li-battery of small dwarf holds the capacity not so long.

Prior to "ride" is thus always reload hip. Clear point deduction in the A grade!
Recommended with reservations.
