Solar-Powered Remote Control
If you think about the electrical devices that eat batteries around your house, the remote control is probably pretty high on your list. And when your TV remote inevitably runs out of batteries, you will probably steal some from the Air Conditioner remote, starting a vicious chain reaction of battery swapping.
You’re better than that.
For the price of about four AA’s, you can liberate yourself from the battery swap forever. This solar-powered universal remote pays for itself almost instantly.
