Waterpowered micro generator for converting flowing water into usable electrical energy. Designed for easy installation on standard household 1/2 inch water pipes and suitable for charging small batteries, powering LED lights, or supplying lowvoltage electronics. Key benefits Converts water pressure and flow into DC power, providing offgrid or auxiliary power where mains power is unavailable. Compact, lightweight design for simple inline installation on 1/2 inch household water pipe (outer diameter 20 mm, inner diameter 13 mm). Multiple output options to match different applications: unregulated voltage output, regulated 5V USBstyle output, and regulated 12V output for common small devices. Clear housing for quick visual inspection and stainless steel shaft for durability in wet environments. Models and output behavior F5080V: DC 080V unregulated output. Output voltage is proportional to water pressure and can reach a peak of 80V. Can directly drive 312V 10W LED lamps and charge small batteries. Charging peak current about 220 mA; when a battery is connected the voltage stabilizes near 14V as generated power is used for charging. F505V: DC 5V regulated output. Includes voltage regulation and charge management suitable for charging mobile phones or lithium batteries with proper charge control. F5012V: DC 12V regulated output. Can supply 12V radios, LED lights, and charge 12V batteries. Practical applications Remote cabin lighting: power LED lamps from a running stream or household water flow without mains power. Emergency charging: charge small batteries or mobile devices using water flow during outages when mains charging is unavailable. Offgrid electronics: supply lowpower 12V radio or sensors in irrigation or pump systems. Installation and compatibility Designed for inline mounting on standard household 1/2 inch water pipes (outer diameter 20 mm, inner diameter 13 mm). Installation is selfcontained and suitable for typical household plumbing with compatible fittings. Materials: plastic housing with stainless steel shaft for corrosion resistance where metal contact is required. Color: transparent housing with yellow components for visual reference. Key specifications Physical size: about 88 x 39 x 58 mm Weight: approximately 90 g per unit Voltage options: 5V, 12V, 80V (model dependent) Output voltage (unregulated): DC proportional to water pressure; listed AC output 020V in specifications Output current: 0150 mA nominal Peak output current: 220 mA (with 12V charging conditions) Flow range: 318 L/min Operating pressure range: 0.150.8 MPa Starting water pressure: 0.05 MPa Peak pressure closed outlet: 0.6 MPa Peak pressure outlet opening: 1.2 MPa Line resistance: 10.5 +/ 0.5 ohms Insulation resistance: 10 M ohm (measured with DC 100 megohmmeter) Axial clearance: 0.21.0 mm Mechanical noise: 55 dB Construction material: plastic plus stainless steel shaft Usage notes The F5080V model does not include a voltage regulator; output voltage varies with water pressure and load. Use appropriate charge control or load matching when charging batteries. Regulated models F505V and F5012V include voltage regulation suitable for direct charging and powering corresponding devices. Allow for slight color variation due to lighting and a dimensional tolerance of 0.52 cm due to manual measurement. This generator offers a compact and practical solution for converting water flow into electrical power for small devices and lighting, with model options to suit different output requirements.
