The delivery was fast and the accessories in the box really extensive. Unfortunately, my fears regarding the quality of the device itself was confirmed. Lt. "Manual", the unit must only by qualified personnel (?) To be installed. The explanation for this can be seen from my perspective at best in the Instructions Manual itself. The charger has two jacks, two LEDs and a switch; the "manual" is so poor that none of these basic control element is explained. The drawings in this connection also provides no evidence to connect. But since it basically by browsing the network and discharges from the pack images is possible to grow it, I did it. Charging an iPhone 4 does not work, like the 4S from other reviews - I have a lot of thinking to dare to close it. In addition, there is an absolute good weather device without any weather protection. Therefore remain for me two stars left: one for the accessories and one because it is probably still some equipment out there that can be loaded with it. A clear "no-buy" recommendation.
