well, lessee. Let's say the batteries are "18V" and 4Ah each. 4 of them. 18V average. Nah, let's call those 20V to make Dewalt and its customers happy. That's 320Wh. The inverter is advertised at 1800W it seems. So it would run at 1800W for errr... 11mins... No no, they say, they really should be 5Ah. OK, then, 14 mins...
