Accu force Packet

I was very skeptical of this power pack, but I'm an avid hiker with hiking Navi "Ibex 30" by Falk. Unfortunately, the battery is always about 2 hours empty. So I ordered my Powerpack and tried it out the same. The Navi was completely empty and I closed it at the store. After about 1 hour and 15 minutes my navigator was back to 100% filled and I could also use the Navi while charging. After charging the Power Pack was discharged down to about 15% (according to status display). I am totally thrilled and would recommend the device only währmstens, particularly why because it is no larger than a I-Phon and relatively easy. The accessories with all adapters and power supply for charging the power back is plentiful.
