Using this on a DLP and rack stereo, but when i hooked it up to a floor fan to run it down, it changed speed dramatically when the mains where pulled. Ran the fan for more than 4 hours on the first charge easily. Havn't tried to run down on the Mitsubishi, cuz don't want to fry the bulb.
Which is why i got this after a power hiccup.

Don't think it is a very clean modified sine, but havn't scoped it. Havn't been able to turn off the beep on this one or its little sister either, tho it says you can ?

BRIGHT blue display, and nice to see the mains voltage fluctuations on the screen from across the room. Narrow and heavy, good build quality. decent spacing on the hot plugs. Happy with it.

Overall, a good deal for the money.
