The F50 is a compact 12V DC micro hydro generator that turns moving water into electrical power for small off-grid projects. Connect it in line with a flowing water supply and the internal turbine spins a DC generator, producing up to 220 mA at 12 volts — enough to trickle-charge a small battery, run a low-power sensor, or power a demonstration circuit directly from a stream, garden hose feed, or rainwater line.
At just 90 grams, the yellow POM and polycarbonate housing fits into tight DIY builds without adding meaningful weight or bulk. The smooth, corrosion-resistant body has no mounting base to work around, so it drops into a pipe run with a simple assembly connection, and its smooth, enclosed housing is built for constant contact with flowing water. With mechanical noise rated at or below 55 dB, it runs quietly enough for a cabin, greenhouse, or backyard test rig.
This listing is for the 12V version only. Output rises and falls with water pressure and flow: the unit starts moving at just 0.05 MPa and handles up to 0.6 MPa on a closed outlet and 1.2 MPa on an open outlet, so it suits low-pressure gravity feeds as well as pumped lines. Because the output is unregulated DC that tracks water pressure, pair it with a suitable charge controller or regulator before connecting sensitive electronics or a battery bank.
For larger water-power builds, compare the F50 with the 2–3kW gearless permanent magnet generator and the 10kW three-phase micro-hydro generator, or browse the full Micro-Hydro collection for turbines matched to bigger streams and higher heads.
