Consider the following as an estimate based on a typical car battery specification of 70Ah:  If the Cobra POWER 500 is fully loaded to 500 Watts and drawing that energy from a 70Ah rated car battery it should continuously operate at that output for about 1.5 Hours.
The runtime figure calculation can be improved with the actual battery specification, AC load value and including the efficiency of the inverter (90%).  If the battery and load values are known then look to the web for runtime calculators to get the best estimate of operating time.
