• High efficiency, long lifespan.Size: 82 x 42mm/3.23 x 1.65"(L X D)
• Low flow loss and low water pressure.It outputs 12 Volts DC at full flow
• this is a generater not a pump it takes a good amount of water flow to get it to generate a small amount of electricity
• while it is a submersible pump, the wiring connectors are not sealed. use the threaded hose connections to gather water and keep the wiring above water
• Water runs threw it and generates electricity.unit will charge a batt but if you have no water flow it will act as a motor and start running
