Review on Sunnytech B032 USB Mini Solar Panel: Efficient 2W 6V Polysilicon Epoxy Cell Charger Module for DIY Projects by Ryan Cornelison

I like that I don't have to look for or buy separate solar panels for my needs. It comes in a package that you can choose from for all experimental uses. I've used mine primarily to power DC motors, charge batteries and LEDs. Don't forget to remove the plastic protective film from each solar panel to achieve full potential performance. Light sources such as sunlight, incandescent lamps with a power of 100 watts or more are most suitable. An LED light bulb of 100W or more also works quite well. After all, experimenting requires you to have time and patience to achieve your goal. Enjoy! Thanks. George. NYC, NY
