    Recommendation for laptop power inverter

    So I've been using a 150w power inverter which I purchased from home depot, to power my laptop. It has worked out great, until the other day when it finally went on me.

    I have since tried looking there again, but couldn't find it. I also bought a similar one from Home Depot, but once it was powered in the car, it flipped to "protect" mode immediately.

    I have also tried using a Carnetix various times, and have never had one work consistently. They either crap out after a month, or all of the lines don't work, so I'm finished with that money sink.

    Can any of you recommend a power inverter (or alternative way of powering the laptop in the car) which you know will work, or personally have used?

    Thanks,

    -Dave

    I hope you win.

    My suggestion would be to look at some of the kensington automotive laptop adapters, they have a few to pick from, and they're a one-adapter-fits-all type of solution. There are different wattages available, it might be good to know what laptop you're trying to power.

    Too much coffee today I suppose.

    I'll take a look at those. But all I'm seeing at the moment are laptop adapters, which do not convert to a vehicle's native 12V DC output.

    Ditto.

    dc-dc is preferable since laptops etc already have a dc input.

    I recently got a smaller (I think 17-24V) 45W unit for an MSI Wind (19V) for $25.
    But you'll probably need a bigger unit (90W, 120W etc).

    My google-fu is strong today. This adapter does it all, wall power, automotive power, and airplane power. A DC to DC like that would be good. I'm not saying kensington is the end-all, that's just the only manufacturer I could think of off the top of my head that made a generic one.

    FTW!
    The Wall/Auto/Air is pricey, BUT considering it has AC as well, and universal AC at that! And a reasonable 90W. And good efficiency. And...

    (Though I like redundacy, hence two units else cheaper dc-dc with backup inverter & plugpacks etc - which is good when traveling in own vehicle etc, but not for lugging around manually!)

    I got this one not too long ago for under $25 bucks and it seems to work as you would expect it to. It stays pretty cool, since I had been shopping for one with a much higher wattage than my puter even needed:
