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

Works, but performs a little less than described (approx. 70 percent of described) in full sunlight and can hardly light up the smallest LED lamp. I had to choose a much larger power supply so it could be used for a student classroom demonstration. It's nice that the product includes a protection circuit that should be useful. Please note that the item is non-refundable.
