Whether it's a smart speaker, waterproof system, or integrated, the shower is a popular place to listen to music. The Shower Power brings Bluetooth audio to bathtime in an eco-friendly way. Its proprietary hydropower system uses the flow of water to spin an impeller that's connected to a mini-generator, producing enough energy to power the speaker and charge the battery at the same time. It installs between the pipe coming out of the wall and the showerhead, making it compatible with nearly any setup, and can run for up to 16 hours after the water stops running. A waterproof remote can control the proceedings if the onboard controls are out of reach, a sound wave amplifier sends audio in all directions, and the body is made with 100% recycled ocean plastic.
