answer 1
The time rating for the 120 volt output in the previous post, does not relate to the battery life. This unit has a power inverter in it that can supply 400 watts for up to 5 minutes before it needs to cool. This inverter can supply 320 watts continuously without having to cool. The batter life in this power pack is approximately 20 Ah (Amp hours) @ 12 Volts. That means that on a full charge the battery would provide 300 watts of power for 45 to 50 minutes.

answer 2
Battery is only 12v, 20 Amp hour. Guess that's about 240 Watt hours. Certainly it is not suitable for extended uses, but should be adequate for a small lamp (60w) or two for a couple of hours.
