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:
