Cheap Solar Pad
This kit is just brilliant! It allows you to charge any set of batteries using solar power, which means that those batteries will last forever.. almost. Included in the SunMod Kit is a flexible 4.8V solar cell with solar metal connectors, mailable packaging and double-sided tape. You’ll see for yourself how long you’ll have to keep your alternative-powered electronics straight into the rays of the sun.
