running, but the normal voltage drop that occurs during starting of the engine may trigger the inverter’s low voltage shutdown feature. Because the power inverter draws less than 0.25 A with the ON/OFF switch in the “ON” position and with no AC products connected, it has minimal impact on battery operating times.
The battery operating time of the XPower 450 depends on the charge level of the battery, battery capacity, and the amount of power drawn by the AC loads you are operating. With a typical vehicle battery, you can expect the following:
