Handy Power-Pack with astonishing capacity

After this external battery is now almost 2 months in "hard" use, I want to share the still existing enthusiasm.

First, the scope of supply:
Battery, 2 spiral-microUSB cable, cloth bag, no charger
+ The spiral cable is extremely convenient because it can be stowed away quickly and without tangling. Extended length about 40-50cm, but then with the appropriate train-voltage ;-)
+ Also the supplied cloth bag with the drawstring closure is very convenient, you can insert the mobile phone when charging the same time and (a and a battery in the mobile phone) let the two plugs sticking out above.

Function:
+ The battery has an amazing capacity: the LG 4X HD with its 2150mAh battery can be fully charged about 4 times when it is added at about 10-15% of displayed residual capacity.
+ Is compatible with all previously angestöpselten mobile phones and smartphones have been, including "normal", such as the Nokia 6303i. So far successfully loaded: Nokia 6303i, C7, Samsung S2, Galaxy Nexus, Galaxy Y, LG 4XHD, L9. Tablets I have not been able to test.
+ Due to the high charge current possible no difference in cell phone-charging time for the power supply is determine felt even more rapid, but that can be deceptive. Whether in fact a tablet with 2A is loaded, I can not judge, as not proven.
+ Rounded shape: the battery can be worn in your pocket without the corners stick out, as is the case with "square" batteries.
+ Good residual capacity display is not particularly fine resolution (4 LEDs), but it seems to me quite accurate and reliable.
+ Automatic switch when a device is connected for charging

The only minus point is actually none, considering the high capacity: Charging time will also use a 1A-mobile power supply (whether from Samsung or LG) his time, with ~ 14h you have to expect when the battery was evacuated.

Conclusion: form and function perfectly for my application, also still quite inexpensive when compared to competitive devices. Would take this battery again.
