Hydropower separation technology, clutch coupled with dual magnetic circuits, the volume is only 4/5 of that of ordinary micro-hydroelectric generators, but the output power is 2-3 times that of ordinary hydroelectric generators.Ingenious structural design, the angle of the inlet and outlet pipes can be installed in a straight or L shape according to the requirements.Reasonable waterway design, low flow loss, low water pressure (0.05Mpa) start, and smooth start when the load is short-circuited.After being isolated by the diode, it can directly supply rechargeable batteries below 3000MAH or Farad capacitors below 5F for charging and power supply. It is a good partner for smart faucets and induction faucets.This product has been applied in a large area for many years, and after multiple optimizations, it has a good cost performance.colour: blackMaterial: PlasticPackage Contents:1 x DC generatorOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
