Review on 🌞 Sunnytech 1pc 3w 9v 333ma Mini Solar Panel Module Epoxy Solar System Cell Charger DIY B043 for Improved SEO by Ron Chang

This is a really great product. Well made and very handsome. The output matched my meter. I had to solder two wires to the back, which turned out to be easy. There was a good set of copper traces on the back for soldering, similar to soldering circuit boards. I cannot praise this product and price enough and will definitely buy again! I also received a very pleasant letter from the seller and a free rectifier at the output. The only advice I would give is to pay close attention to the position of the traces and your solder straightener. They are easy to spot as there is an icon on the back for where the rectifier is placed. There are also exits in the place of this symbol. I soldered mine and started using it in two minutes. I use such devices and technologies in my work and I was also very impressed with the result I was able to get when testing in different lighting conditions. Of course, as always, full performance is measured by the measure of a full sun, but in my experience the panel can be impressive even with less. Of course, as with any high quality electronic device, use a good quality soldering iron and solder.
