Underwater Shake Light

Characteristic (SB-3072) Working Principle: This product uses the principle of electromagnetic induction to make it work. When you shake the flashlight back and forth, a strong magnet passes repeatedly through a wire coil and generates alternating current which after commutating to charges its built-in 40 mAh storage battery . Then by turning the switch for lighting and flashing. Functions: 1. Electromagnetic energy to generate power for the lighting and flashing of 1 LED . 2. Waterproof and moistureproof : This can be used in water under 2 meters. 3. It can float on the water. Features: 1. Convenient to use, no worry about power off, shaking to meet an emergency. 2. Electromagnetic energy to generate power, the generating efficiency is multiplied by adopting patent double wire coil. 3. Transparent shell and colored wire coil designed, artistically aware, exquisite. 4. Applied in a wide range of area: in shallow water and other high humidity places. 5. Low cost: never need to consume other energies.
