Check out this unique way to power a radio in the shower. Normal shower radios have the mess of dealing with batteries, but not the H2O Shower Power Radio. Nope, it runs on water pressure. The entire radio is waterproof, so there’s nothing to worry about on that end, and it stores excess energy so that it doesn’t die when the water is shut off. The only thing to consider before purchasing would be the installation and removal of your existing shower head. $56 gets the radio and a new shower head, so that’s not bad.
