Since the desired solar charging does not work, only 1 star.

I have bought my unit, because it will help me to multi-day trips to keep my cell phone, which also serves as a traveling-Navi alive.
First Impression:
After unpacking the cabinet worked very well processed and stable, but the solar cells extremely dirty and blistered. I wanted to have return as Poor.
These goals could fix but because there is much to that the bubbles could be moving, so it was merely a protective film, which erroneously was pinched in the housing. Here Pearl should perhaps point out to the installation company at a time cleaner working ... with the low price, it can not excuse that. Mag also have been an isolated incident.
I had to solve 2 screws to remove the foil from the shell, but that was not a problem. After this, the solar cells prepared just as well made show how in the local photo.

The loading functions:
I have in my phone a battery with a capacity of 2020 mAh.

1. The outlet: ließlig With my cell phone charger; the unit charge without problems.
2. On the computer: connected with the provided cable to the computer and you're done. Here I have the battery in addition are allowed 2 days to see if it holds the juice.

In both cases, the charging of mobile phones was completely empty battery with no problem, loaded it completely.

3. The solar cell: Here stood the "test" pending. But he was not only unsatisfactory, but sobering.
All Positive these small handy construction is thus destroyed. It has no Ladeefekt when it is exposed to the whole day the sun. Thus, the device is suitable for me as a memory for 2-day tours while I'm charging him at home, but as a travel memory, it is not suitable, because the solar charging function does not work.
I have this all day EXTRA mounted on the backpack, in a Klarsichhülle. It was suspended by 10 clock bis 17 clock almost durchängig the sun.
The device also shone always a good boy, I constantly checked. But the charging effect just made on your mobile phone times ridiculous 2 percent and the charging process stopped just 30-45 min. By connecting the device to the battery of my mobile phone was at 9%, then 11%. What the cell phone was not usable. As I had expected better.
Oh, and before I tested it with the connected device ... Fals who wanted to interject here ... unfortunately also here no effect.
