The Input Power Factor. A battery powers the inverter. Batteries have an amp-hour rating, the theoretical number of hours that a battery can deliver a current of 20 amps. A fully powered 200-amp-hour battery delivers 20 amps for 10 hours. A lower amp-hour battery will deliver 20 amps for less time.
Re: car battery. Say the battery runs the starter for n seconds at 100 amps. The alternator can deliver about 50A so it will take a little over 2n seconds to recharge the battery if there is no other current drain on the alternator.
