Here is a Bluetooth speaker powered by water that lets you enjoy your favorite music and podcasts as you take a shower. Shower Power by Ampere is made from recycled ocean plastic. It turns on automatically when the water flow starts. Its hydropower system works like a water wheel.
Shower Power uses a “sound wave” diffuser to send sound in all directions for 360-degree audio. It comes with a convenient waterproof remote. This speaker stays on with water running at PSI of 30 or above. With no water running, you still get 14 hours of listening time thanks to Shower Power’s 2600mAh rechargeable battery.
