Self-sufficient from Germany to Italy

I have long been looking for a solar cell, which brings not only a few percent in the battery, but effectively invites also available in widths to Berlin.

Although I am not clear why anchors indicates 14 watts, but where the power from voltage times amperage results, ie 5V times 2 amps = watts maximum 10
Nevertheless, the cell has a lot of power!
In Berlin in June the cell reaches around noon with good alignment over 1.7 amps, the best performance that I could measure under the same conditions under various getetsteten cells.

In an 8-week cycling tour from Berlin to Naples, the cell has supplied me despite mostly cloudy weather with reliable electricity.

However, one must note that fluctuating currents in charging current to cell phone battery damage (not must, but can ...)

In order to avoid this and also save electricity can, I recommend the use of a buffer battery.
ATTENTION: This buffer battery must be expressly recommended for use with solar !!

The cell is very tolerant gegebüber clouds, non-optimal orientation and so on, in spite of everything you usually still reaches 1 Amper (5 watts)

But since you can load so throughout the day, it is quite effective, especially for the price !!

Also a plus: Multiple eyelets for attaching

One drawback: legal high weight (but very low price !!) you just have to know what you want ...

Would I buy it again at any time and weiterempfehlen.Bestes price Leisutngsverhältnis !!
