Short and sweet - the thing fired both the Kindle Fire HD and my smartphone or other devices and loads such as an empty HTC One S within not quite 1 hr FULL. Now the huge disadvantage - and I can not even tell me how to do this: No matter what device this charger depends whether Kindle, smartphone, Kindle Fire HD, Digital recorder, etc., then each display "locked" and become unresponsive. Once you separate the Lädegerät from (eg Kindle), all is well again. Conclusion: Fast upload and not use that device in time. I personally would not buy this charger again because something is uncomfortable.
