BENCHMARK / TEST DATA

This data was recorded using a WattsVIEW power monitor while charging a 12V Deep Cycle Duracell Battery Powerpack during a one-hour charging session.

For more information see the FAQ WEBPAGE.   If you want to buy a generator stand ready to go out of the box then go  HERE.

Generator Voltage Output Vs. RPMs

The data below shows actual data from a belt – pulley generator during a one hour bike riding session.   Remember that Watts  = Volts X Amps.  So the 2nd chart below (green chart)  is Watts which is simply the product of the red (Amps) and white (Volts) lines of the first chart.
