Great addition to the running gear

Since I run longer distances while over iPhone music listening, the Laufapp, Bluetooth (heart rate belt) and 3G'm wearing (the sake of better GPS reception) sucked the good mobile phone battery always threatening empty.
Alternatively, I would have a newer model to bring the phone to ever to have significantly lower Bluetooth-related power consumption and a better GPS signal (thereby perhaps no 3G, which also significantly saves electricity).
As for me, but unfortunately just not 650 or even 800 lying around, I stumbled over a PowerBar and I've finally decided on this model.
Only if one of the bar compares prices of new iPhones ... :)

It loads quickly and I can start with NEM fully charged mobile phone and to run more than one hour of mobile phone battery is still at 100%. Running the battery rarely hurts, because it fits through the narrow shape in just about any pocket.
Also great gimmick: At one end is a kind of hook, so I can hook my carbine from running belt super if me the good piece slips times out of his pocket.
In addition, he is neither loading nor when discharging grand heat, as far as I remember correctly.
Connectivity options are USB and MicroUSB, but I was glad that I have a PSU with USB port anyway. However, one must at the price and not expect :)
The battery loses 1-2 of 4 power status lights, so I will therefore so run comfortably the half marathon.

Conclusion: all-round happy and makes the battery what he should: He keeps me energized while I turn my rounds and there are 15 much better than 650 + X and the value for money is good also all times.
