Have at least a structurally identical part for years in use. Was my "home" in the matter. The idea was to use my phone as a Navy in motorcycle tours. The mobile phone, in the end a Nokia N8, was in the tank bag with a transparent film. On headphones connected to my head. Display. Offline maps were rare. At that time. So the phone at maximum output online. I digress. We are sorry! Day trips 1000 km were not a problem. "With" the battery pack! Today I use the battery pack, under a canopy hangs in conjunction with a 14W solar panel with "wind and weather" for energy storage. And just load up a Samsung "Note 2014 Edition" so on. The load curve is not quite as steep as the power supply, but akzeptebel.Wer 5000mAh examined inexpensively is with this unit is not bad advice.
