Review on 🌞 Compact Sunnytech 0.5W Solar Panel Module - DIY Charger B016 (5V, 100mA) by Robert Ducki

I really don't know what other people are complaining about: I'm an EE and this cell is well made and appears to be weatherproof. The wires are well bonded and of good quality. As with all solar cells, direct sunlight is required to provide full output current and voltage. I use it to charge a tiny 3.7V battery.
