Toto's Aqua-Electronic Technology

September 3, 2003
TOTO USA introduces EcoPower, the first sensor faucet whose power source is completely self-sufficient. It generates its own electricity every time water spins its small internal turbine. The energy is then stored in a rechargeable manganese dioxide lithium battery. With as few as five uses per day, EcoPower’s battery life exceeds that of most public restroom sensor faucets.
