How long will a 2000 watt inverter run on a car battery?

If you max out the inverter at 2000 watts, you are pulling 2000 watts /12 volts = 166.6 DC amps per hour. If you use a 200-amp 12-volt battery, you would divide the 200-amp battery / 166.6 amps = 1.2 hours of run time. This is if you plan on fully depleting the battery, which we DON'T recommend.

How long will a car battery run a 300 watt inverter?

A 300 watt inverter can run up to 10 hours on a 12V battery but run 6-7 hours on an 8V battery. So it all depends on the battery used and the appliances to be powered. But on average, a 300 watts Inverter will last between 7-17 hours before a total shutdown.


How long will a car battery run a 400 watt inverter?

If your battery has a 90 hour rating, you should be able to run a continuous load of 400 watt for 2 hours. The longer the battery lasts, the higher the Amp hour rating is.

How long will a 12 volt battery run a 1500 watt inverter?

A 1500 watt AC Power Inverter will run for approximately 16 hours based on the 200 amp hour rating of your 12 volt battery.
