This is what I have.

There are a couple reviews on YouTube about this one.
It actually works VERY WELL. It powers our 900w microwave without a hitch. The wife was using a curling iron, while a 90w TV was on, and I made popcorn. Had no troubles.
The Fans are loud, and move a lot of air. This will not be a problem if its stored below.
Its standby amperage is 0.2 amps.
I assume it could run a small AC, but have yet to try. I bought the Amazon offered insurance for a one time replacement (no questions asked) if it should ever break for an additional $12.99
I tested it myself and it is a true pure sine, and keeps a true wave (and voltage) while under load. Many cheaper PS inverters have a very distorted sine wave while under heavy loads.
I have two 1/0 ga wires from each pole of the batteries feeding it. I have 150amp fuses inline on each pos pole.
You MUST have an inverter as close to (but not in same compartment) the batteries as possible.
