I have now tested the battery pack for a week while on a variety of devices. When fully charged, it can in an emergency two smartphones (Xperia Z) and a Kindle Paperwhite complete load and still has decent reserves in stock for a TomTom navigation system could be after that "refilled". Especially when Kindle I was not sure because this before one or the other charging cable in advance has rejected. However, with the accompanying adapters represents the charging is not a problem. With approximately 325 grams of the battery pack is not the lightest, but it has enormous potential. Finally, I wanted to know exactly, and then again times have drangehangen a 7-inch monitor. I need this for example for outdoor shooting with the camera crane. Usually no power sources are there of course available and one is forced to resort to batteries. And what can I say that Powerpack held 2.5 times longer than the supplied battery to the monitor. Enormous power! For these reasons, I can recommend this without any reservation any part. Five Stars!
