We used it to power our small (1050w input power) microwave just fine. However, when we tried to power our 11k BTU a/c (1320w) with a Micro Air Easy Start installed, it was a no-go. Based on the Xantrex's 1800w continuous and 3000w surge ratings, it should have been a go. Max inrush current (LRA) on our 11k a/c unit with the MAES installed was less than 20a (2400w)---well within the Xantrex's 3000w surge rating. In any case, we swapped the Xantrex for a 2000w Aims high-frequency PSW inverter. All is well now.
I'll check that stuff tonight. Maybe I should have got a 3000W for a cushion?
If you go with a larger inverter check the parasitic (no-load) current ratings. If you dry camp a lot, it may be something to consider. Some 2000-3000w inverters can have a parasitic as high as 2-3a. Both the Xantrex Prowatt 2000 and Aims 2000w PSW inverters have a low parasitic of .6-.7a (realworld current readings; specs are higher).
Again, good luck with everything!
