POWER SOURCE
Your average automobile or marine battery at full charge will provide an ample power supply to the inverter for ap- proximately 3 hours when the engine is off. The actual length of time the inverter will function depends on the age and condition of the battery and the power demand being placed by the device being operated with the inverter.
Turn OFF the device plugged into the inverter before start- ing the engine. To maintain battery power, run the engine every 2 to 3 hours for approximately 10 minutes to recharge the battery. While the Power Inverter 140 draws very low amperage when not in use and it should be unplugged to avoid battery drain.
