There are two basic types of generators to choose from. Belt – Pulley style and roller style. They can be ordered from Amazon or directly from us to ship internationally for a shipping cost of $100 to $300 depending on how fast you want it shipped and to which country.

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.
BENCH MARKING / TEST RESULTS
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.
