For product:
Processing / Appearance:
The solar panel is well made, the seams are absolutely great for the price.
This it is foldable (about the size of an A4 sheet), it can easily be stowed in a backpack. By 4 eyelets on the panel, but it can also be very easily attached to the backpack, which you can load his smartphone / GPS device, etc. even during the wandering, of course only as long as the panel is sufficiently shines. Furthermore, it has a small pocket in which there are 2 USB ports, where you can for example accommodate the Smartphone during charging (Warning solar panel in the sun is very hot)
Power:
The performance is of course always depending on how much sun abbekommt the panel, with how many amps the device is charging and a maximum of what quality is the charging cable. In low charging cables can cause performance degradation to 20% on up, so I recommend several charging cables to try to ensure the highest possible yield to have.
My tip: For me, the AmazonBasics cable very good values and have shown they are qualitatively superior.
I have tested the solar panel with two USB PortaPow meters and came to the following conclusions:
- So I had in full sunlight (All 4 panels irradiated) without clouds a total output of 1.86 amperes and 5,07V what the promised 2A already comes very close.
- In case of partial shading (about half shaded) I had a total output of 0.95 amperes and 5,04V, which is still loose enough to invite his smartphone or possibly a good Android tablet slowly.
- In cloudy weather, I still had a total output of 0.66 amperes and 5,04V, thus one can despite clouds still charge your smartphone.
Conclusion:
Compared to other manufacturers of similar products, this solar panel in my opinion, the absolute price / performance hit because it offers a good workmanship and maximum value for your money.
So if you want to load only 5V device with a solar panel, which is very well served with this panel.
Furthermore I bought more at that panel anchor Astro E5 Power Bank with 15000mAh, prima as backup battery for the solar charger is (unfortunately had to find that the anchor Astro Pro2 Power Bank with 20000mAh, is not geeigent for charging with this solar panel) the
