Features: The power required for LED showers does not require additional batteries and power supplies to supply, and is completely environmentally friendly and energy efficient through water flow. Self-generation: relying on water pressure to drive self-generation, no power battery, safe and environmentally friendly. Motor: High-speed magnetic motor is used to ensure that the generator is normally driven under normal water pressure for the bright LED to emit normally. Inner core: The inner core part is fully enclosed to ensure long-term contact with water and will not rust. It ensures high working efficiency and stable working condition of the motor. Notice: Actual color may be slightly different from the image due to different monitor and light effect.
