For a business trip to China, I was looking for a reliable way, private and service phone away an electrical outlet to recharge. For this to be able calms immensely. At least me. After a short research I decided for this unit and I'm absolutely happy with it. It is small and light enough to no problem getting to be there and has enough power to be able to a mobile phone (or two) load several times. And not just on the go: I use it just like that, for example, at the desk where actually had a power outlet nearby. I even think it makes the phone battery somehow "correct" full. The phones last longer. Measured I but nothing is more felt, underpinned scientifically. Convinced have me as the comments to customer service. As is really communicating with the customer and not abgewiegelt, which I think is very good, even exceptional in this day and age. The packaging and the manual are outstanding compared to many other products. The part is now one of my standard equipment. Quasi my Swiss Army knife for the batteries. The feel is great and the service super easy. The indicator looks awesome and leaves no doubt about what is just cause. Shall be recognized intuitively. The finishing touch is the included pouch from a 3D tissue, on the one hand, the device offers good protection, but on the other hand, can shine through the light indicator. A colleague of mine was probably immediately convinced of the part, as I had shown him. Two days later, he also had one. Oh, no, I'm not getting paid by anchor. I think it is commendable if we nowadays still gets products in which at least one has the feeling that it is an "honest" product. Whether this is really so, remains to be seen but I'm optimistic. In the urban jungle and go it has proved its worth and always gave me the certainty to always have enough power while.
