Do not buy...unreliable...no service for repair

A plastic gear in the compressor was stripped after just one year of use (the compressor was used maybe 5 times). ^M
Xantrex would not service the unit (at any cost), sell a replacement gear, or provide any discount on a replacement unit. ^M
Don't buy this.

Great product, works as advertised. Tested some actual run times.

I bought this mainly for some kind of backup power during our hurricane season in Florida.^M
I tested the following items separately to see what kind of duration I'd get:^M
^M
Dell Inspiron 8100 laptop - 4.8 hours before alarm sounded (uses 70 watts)^M
Emerson 13 inch color tv - 4.1 hours before alarm sounded (uses 72 watts)^M

The unit actually came almost fully charged for me. When recharging after totally drained it took about 30 hours until I got the solid green light. One person had a great idea, during a power outage for a couple days, and after using up all the juice in the generator, he used his car to recharge it. It says it would take 3 hours to charge a fully drained generator through the cigarette lighter but when you don't have power for a week, that's a nice way to keep the unit going.^M

Not for tire inflation

It takes about 2-3 minutes to inflate a 44psi max 15" low profile tire on a '91 Acura legend.^M
While inflating the fourth tire, the compressor failed.^M
Total run time was under 10minutes and I let the unit rest 2-4 minutes between tire inflations.^M
I have not tried the other functions.
