Mini Monocrystalline Silicon Solar Panel with Charger

The system works well, however I have a small complaint: the LED indicator may consume most of the energy charged by the small photovoltaic panel. On the other hand, for this charging indicator, a small soldering point needs to be made depending on the type of battery you have. This is not clearly indicated as there is no user manual.

Good product that works as expected, but you need to adjust the voltmeter according to the number of cells. Here I only had one 18650 battery, so I adjusted it to S1.

Good product, excellent, would buy again.

yes, it has 6 volts 👍🏼 great

Interesting system. It's also designed to help curious kids understand the world of solar cells. It can even be used to power a garden light or a night light without consuming electricity. It's fantastic!
