    EliteBook power supply?

    Hello all,

    I have a HP Elitebook 8530p and need a travel power supply instead of the 180W included brick. Since HP over charge hideously here in Sweden (120 USD for a PSU!?), I'm looking at the 3rd party market.

    The included HP 180W adapter delivers DC18.5/6.5A. I guess this unusual voltage is in order to make it complicated for third parties.

    I see a 3rd party adapter that delivers 18.5/4.9A/90W. Does that work? Or ideas of where to get one that does?

    Thanks in advance
    Dd.

    The guy in the store recommends an adapter that delivers 19V/4.74A. What do you think?

    That is pretty standard for universal replacement - a bit more Voltage and less Amperage.

    It is not worth the savings to go with a 3rd party AC Adapter replacement. My 2 cents.

    cheers ...

    Oh, okay. I guess that's cool then. Any downsides? Longer charging times?

    How come? It's like a fourth of the price... $30 instead of $120. Makes hell of a difference when on a tightish budget.

    IMO build quality is generally lower in 3rd party solutions and if for some reason the adapter fries your laptop, while it probably wont increase your chances of having this happen, should it occur I doubt HP will cover it in your warrenty, while if you fry it with their adapter they probably will.

    But you're right, the price gap is rather vast. Might I offer a compromise solution? Buy a used OEM adapter off ebay. It'll probably still be more than the 3rd party adapter, but more likely than not 1/2 the cost of the one from HP. I'm pretty sure HP offers a smaller 80W adapter for it's 8510p/w line and I do believe it is the same plug as the 8530p/w (BUT DOUBLE CHECK THIS 1ST!) it wont fry your laptop to plug in an 80W adapter since your standard is 180W but it might not have enough juice to do anything. I do believe that the 180W is so high to allow for the quick charging feature, but if you disable this you shouldnt need that much power. My 8510p doesnt drain that much less power to justify a 100W boast from mine to yours. Anyway, goodluck
