I bought this mini hydro generator to see how it works. Let's test it, run some numbers, then tear it down to see how it was constructed. They make 12v, 5v, 80v versions, I got the 12v.
INFO FROM SELLER =================================
Product details of Original DC 5V/12V/80V Micro Hydro Generator DC Water Flow Generator Turbine Generator Hydroelectric Tap Water Flow Hydraulic DIY
12V: DC 12V regulated output, which can power and charge 12V radios, and power LED lights.
Mechanical characteristics and operating environment:
(1) Appearance: clean surface, no rust, no scratches, firm structure.
(2) Axial clearance: 0.2-1.0mm
(3) Mechanical noise: ≤55dB
(4) Generator unit weight: about 90g
(5) Generator life: ≥3000h
(6) Output characteristics: The output voltage without a voltage regulator circuit is proportional to the water pressure
Specification:
Technical conditions:
Output peak voltage: 80V (1.2Mpa)
Output peak current: ≥220mA (12V)
Line-to-line resistance: 10.5±0.5Ω
Insulation resistance: 10MΩ (DC100 megohmmeter)
Water outlet closed peak pressure: 0.6Mpa
The opening peak pressure of the water outlet: 1.2Mpa
Start water pressure: 0.05Mpa
Terminal: 2pin
The model corresponds to the power generation output type:
0-80V: DC 0-80V output, the generator does not have a voltage regulator circuit, the peak voltage reaches 80V, it can directly charge 3-12V 10W LED lights, and can directly charge small batteries, the peak charging current is about 220mA, because when charging The generated electricity is used up in time, so the voltage will be automatically maintained at about 14V, and the appropriate voltage will be maintained so that all the generated electricity can be used to charge the small battery.
5V: DC 5V regulated output, which can charge mobile phones, and can also charge lithium batteries with charge management chips.
12V: DC 12V regulated output, which can power and charge 12V radios, and power LED lights.
Mechanical characteristics and operating environment:
