Welcome to our store! This micro hydro generator is a mechanical equipment that converts the potential energy of water into electrical energy. We offer you 2 types of generators. The F50-80V model offers a DC output of 0~80V, without a voltage regulator, a peak voltage of 80V, and can directly charge 3-12V 10W LED lights and small batteries, with a maximum charging current of 220mA. The F50-5V model provides a regulated DC 5V output, suitable for charging phones. The generator casing is made of durable plastic material. It can charge small batteries, mobile phones, LED lights, and more. The generator's surface is clean, free from rust, and has no significant scratches, with a solid structure. You can choose between 2 models: 0~80V or 5V. Specifications: Condition is new, shell material is plastic, color is black, size is approximately 8.6 * 4.7 * 3 cm (3.39 * 1.85 * 1.18 inches), weight is approximately 94 g, quantity is 1 piece. Maximum output voltage is 80V (1.2Mpa), maximum output current is ≥ 220mA (12V), resistance between line is 10.5 ± 0.5Ω, insulation resistance is 10MΩ (DC100 megohmmeter), outlet closed highest pressure resistance is 0.6Mpa, outlet opening maximum pressure resistance is 1.2Mpa, starting water pressure is 0.05Mpa, axial play is approximately 0.2~1.0 mm (0.01~0.04 inches), mechanical noise is ≤ 55dB, generator single volume is 90g, generator lifespan is ≥ 3000h, and output characteristics show that the voltage without a regulator is proportional to the water pressure. Package includes: 1 x Water Turbine Generator. Note: Please allow 1-2 mm error due to manual measurement.
