8.2 amps printed just above the plugs. I connect a 7 amp load and it immediately trips the internal protection, turns off and the LED turns red and an alarm sounds. By installing an internal wattmeter on the unit, I see that consumption ranges from 1.4-2.0 amps with normal use, making a temporary jump to 7.0-7.2 amps. The supplied cables have been used and the battery is fully charged. I have just ordered a different brand 2500w inverter to replace this one.
