Input voltage: DC 5V Input current: 2A Rated voltage: DC 5V Rated power: 5W Chassis material: ABS 15 seconds of high-frequency vibration. Using high-frequency vibration to induce cavitation of super-strong liquid, acceleration and direct current directly or indirectly act on liquid and stains to disperse, emulsify, and peel off stains. 15 seconds of Super Bubbles. Powerful air bubbles burst through the water to lift deep-seated stains, and the two work together for a better clean. 15 minutes power failure protection. Built-in smart core, automatic timing switching mode, every 15 seconds of high-frequency vibration switching 15 seconds of powerful bubbles, and automatic power-off and shutdown after 15 minutes of alternating cycles.
