My Solar Charger I lie on the balcony. I hear there often on my Bluetooth Speaker music. I have the solar charger always connected to my speakers. Since then I can always listen to music without the battery to run out. I can not say whether or not the part is insensitive to temperature or water-resistant, but a few drops of rain have solar panels on several occasions gotten. So far everything without problems. If it now starts with the frost, I will do it definitely pure.
This solar charger can be thought of as a small folding pocket. If you want to use it, you work from the bag with the three panels and if you no longer want it, it will be folded together to save space again. The panels are incorporated into the bag, which is made of solid black material.
The solar charger is supplied with a USB cable. With the USB cable to other devices can be recharged.
Charging actually works! Once the device would collect the sun, a red LED lights up and a small device can be connected for charging. Everyone should be aware of: The charging time takes longer than directly over the net. Large appliances such as newer tablets or laptops are there far too demanding and therefore unsuitable.
I like the processing in this device particularly well. All seams of the solar panel bag are optimally processed. The panels make a high-quality and clean impression.
Conclusion: So far I can not detect any weakness in the performance. The device loads still reliable, albeit slowly. Even if the acquisition is certainly not cheap and so much needs to be charged, so that calculates the saved power, but remains the feeling of doing something good for the environment. I'm very satisfied. If I still find some mistake I will report.
