I've bought the external battery to grab my battery technically underpowered Sony Xperia Z with a long flight under the arms. That worked great!
For battery, it is high quality and packed safely at home! Who is extremely high and the gaps, and the sockets absolutely perfect.
You can load the battery insanely fast (2000mAh charger Amzdeal), you need only 4 hours to fully charge!
Subsequently, the battery can easily using the supplied microUSB cable to smartphone or similar are connected and loads it insanely fast again. During my 6 hour flight I could easily view Play movies, edit pictures and so on, and then I still had 100% battery, so it's fun!
I can see the strong and handy battery really only recommend it because capacity, size and function are absolutely first class. I would buy the device again!
Kind regards and a lot of fun with this high-quality product
