Welcome to Germany!

Yes, what I want to say because actually my headline? It's simple: In addition to a few exceptions, the weather in Germany can not decide quite. One day we walk around with a thick sweater and a jacket, the next T-shirt. So one should rely on a kind of battery charge is accordingly?

By ordering this solar charger, which has the area of ​​about three credit cards, we also get a short micro USB cable to connect to all sorts of devices that have a connection via such connecting, and thus charge. There are of course a manual, but in English. So: Either you can speak English and is then just as smart as if you would use the device instinctively or you saved not speak English and has some time.
Immediately below the recess on the charger, which is provided for fixing and easy transportation, there are five blue LED lights that indicate each 20% charge. The device is entirely elastomer coated and can be very good grasp and slips off neither from the hand, yet smooth surfaces etc..
The device has two USB ports that can be used at the same course. Which devices should be connected and charged, the device regardless. The main thing there is to a USB cable.

As can also be seen on the packaging, I have attached the part of my backpack and pedaled by bike in the best weather of the area. Every now and then I naturally inserted breaks and so far also observed the charging of the battery. Except for some brief exceptions, the battery was constantly under the sun sets and our trip of about six hours, it has the battery managed to 100% threshold and all LED lights have lit up. How long the battery actually requires at minimum until it is fully charged, I can not say unfortunately. It also ensures highly dependent on the sun's rays, for which you so not exactly something to say.

The iPhone 6 Plus my battery was at 42% when I joined him on the way back home via the USB cable to the battery. At home, after about an hour, it has brought the battery to a whopping 82%, which has not surprised me, but I've always been skeptical about solar energy. Even the iPhone my wife we ​​have incidentally connected and came almost to the same value. But it glowed still two LED lights.
Thanks to the full rubber coating of the unit to attenuate Aufpraller and falls off with no problems. You will even be waterproof in the sense of splash and rain, I neither confirm nor can refute, as the weather is just too beautiful for that. To test this functionality, I wanted to not necessarily go take a shower.

Conclusion:
A not pretty, but effective device to use solar energy efficiently, while just outside stays, when picnicking, cycling, beach visits, etc. Very well done!
