Quite simple really ... I thought. First I tried it with a charger of Wicked Chili, due to the many good reviews, also with iPhones. However, the thing was a big disappointment. The shop was just painfully slow, partly the battery discharged even again. For me, an absolute knockout criterion.
Then I switched to the device of anchor, what can I say: it does exactly what I expect from such a device. It charges the battery quickly, even with Bluetooth and navigation. And waived, as well as Wicked Chili, a LED that particularly annoying when driving in the dark.
5 Stars!
