Product overview A compact water flow generator series designed to convert flowing water into usable electrical energy. Install directly on a standard 1/2 inch household water pipe to power LED lights, charge small batteries, or supply lowpower DC devices. Output is proportional to water pressure when no regulator is present. Key benefits Converts existing water flow into electricity for immediate use without complex setup. Direct charging and lighting options reduce the need for external power sources during flow. Simple installation on standard 1/2 inch pipes for easy integration in homes, gardens, campers, and small offgrid systems. Lightweight and low noise for unobtrusive operation. Models and main functions F5080V: Unregulated DC output 0 to 80V peak. Peak voltage can reach 80V. Suitable for driving 3 to 12V 10W LED lights directly and for charging small batteries. Charging peak current approximately 220mA. When a small battery is connected and charging, the generator output will tend to stabilize around 14V while charging so that generated energy is used for charging. F505V: DC 5V regulated output. Designed for charging mobile phones or lithium batteries with an appropriate charge management chip. F5012V: DC 12V regulated output. Can power 12V radios, charge 12V batteries, and supply 12V LED lights. Performance and electrical specifications Output voltage characteristics: without a voltage regulator the output is proportional to water pressure. Output voltage AC: 0 to 20V. Output current: 0 to 150mA. Peak output current: 220mA at 12V. Line resistance: 10.5 plus or minus 0.5 ohm. Insulation resistance: 10 megaohm measured with DC 100 megohmmeter. Starting water pressure: 0.05 MPa. Normal operating pressure range: 0.15 to 0.8 MPa. Flow range: 3 to 18 liters per minute. Peak pressure of closed outlet: 0.6 MPa. Peak pressure of outlet opening: 1.2 MPa. Physical specifications and materials Size: about 88 x 39 x 58 mm. Weight: approximately 90 g per generator. Material: plastic housing with stainless steel shaft. Installation fitting: standard household 1/2 inch water pipe outer diameter 20 mm inner diameter 13 mm. Axial clearance: 0.2 to 1.0 mm. Mechanical noise: approximately 55 dB. Color: transparent and yellow. Installation and use notes Designed for selfcontained installation on standard 1/2 inch water pipes. Confirm pipe outer diameter 20 mm and inner diameter 13 mm for correct fit. The unregulated F5080V model produces voltage proportional to water pressure; use caution when connecting sensitive devices and batteries. Regulated models F505V and F5012V provide stabilized outputs for direct charging and powering compatible devices. When charging a small battery with the F5080V, the generator may stabilize near 14V under charging load and deliver a peak charging current of about 220mA. Allow for slight color variation due to photography and permit a 0.5 to 2 cm tolerance for manual measurements. Practical use scenarios Household lighting: Install on a bathroom or outdoor tap to power 3 to 12V LED lighting while water flows. Mobile and small battery charging: Use the F505V model at a campsite or remote sink to charge a phone or a lithium battery via a charge management circuit. Lowpower electronics and 12V devices: Use the F5012V model to supply a 12V radio, charge a 12V battery, or power 12V LED strips near a water source. What is included Single water flow generator unit. Follow local electrical and plumbing guidelines when connecting batteries or electronic devices. Safety and compatibility reminders Match the model to the intended load: use regulated models for sensitive electronics and the unregulated model only when appropriate voltage behavior is acceptable. Do not exceed the specified pressure and flow ranges. Ensure secure plumbing connections and proper charge management when charging batteries.
