Special Note:
1) A higher output AVR definitely works perfect on a generator of low power output while on the contrary, a low power output AVR CAN NOT be used for a generator of higher power output.
2) If our AVR is out of adjustment for your generator, please MANUALLY turn clockwise or counter-clockwise a small bronze screw in a blue rubber part(potentiometer) to reach your desirable power output. Clockwise turning is for increasing and counter-clockwise turning for decreasing voltage output. If this does not help you out, please contact with us for tech support.

1 x Voltage Regulator
