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 suing PayPal. We ship world wide. Watch the video below to see how it works.

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.

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.
