Battery empty? Often? No, does not have to!

This device is indeed times really useful. Am thrilled here everything is right.
This energizer convinced primarily with perseverance. However, processing, format, appearance, facilities are impressive.
-Beiliegendes Transport bags (so far not mentioned in the product description) is very useful. It not only protects the battery itself, but also the connected terminal when carrying in your pocket.
-The Included USB cable invite our Xperia and Galaxy smartphones, no compatibility problem as before, sometimes at Samsung
-The 2.0A charger is handy and small enough not to interfere with other plug into the socket. It invites the Power Bank in about 10 hours to complete.
-The Flashlight feature is eg useful in the tent and it also sufficient. Is obviously no substitute LED Lenser)

The most important thing, however, it invites all we have so daily use, completely on - if needed even 2 devices simultaneously:
-iPad3 and iPad Air, iPod
-Samsung Galaxy 3, Sony Xperia Z

With the Xperia Z (2330mAh) I tested how many times I can charge it completely. I was able to load the switched mobile phone 5 times, that is, I'm depending on the use of mobile phones without power from 7-10 days. The Power Bank charges while the phone faster than the original Sony charger. The charge stems again 6. 35% mobile phone charge.

What we was still important for outdoor activities:
The Power Bank can be easily under a cloudless sky on the invite "RAVPower® 15W solar charger". If it is cloudy it does not work, then the energy produced is too small to load this powerful battery, clear!

We speak of a strong buy recommendation! Because there is in our view absolutely nothing to complain about.
Oh yes, there is a 12 month manufacturer's warranty, which is extended with online registration for another 6 months.
