    Just a note that Costco (maybe not all stores) has a 2 pack of Vector 70
    watt mini inverters for $24.99. These are the tiny ones where the whole unit
    plugs into the lighter socket. They work great for laptops etc..

    I bought the same model from Walmart's auto department for $15 apiece.
    They are rated 60 watt continuous, 70 watt for 1 hour, and 140 watt
    surge. They weigh a quarter of a pound and are about the size of a duplex
    cigarette lighter plug. The draw at idle was only .25 amps at 13.5 volts.

    I was using it to power a wall wart that produced 12volt AC for my DSL
    modem. It worked fine for several days and then the modem started losing
    sync with the far end. I'm not sure it was related, but couldn't afford
    to let it ride. I'm back to running it on house current until I can
    open the modem up and look at the possibility of running it from 12V DC.

    On the other hand, I've thrown one of these compact inverters in my
    computer bag to power my laptop when I'm on the road. It replaces a
    $75 DC-DC converter from Radio Shack that weighs about a pound.

    I looked at the output on a scope (running without load). It's a modified
    square wave that looked pretty clean... basically a square waveform with
    rounded corners.

    I bought a couple more from Costco for use as spares :)
