    You can get 16V power supplies that fit a toughbook for $11 shipped on ebay. Just spend the $$ and be done with it.

    Well i was hoping that it would work in all of them as i am getting a cf-18 in soon and it does not come with an AC adapter.

    Now i can just use my CF-30 adapter.

    Thanks Guys

    tolerable voltage amount to be safe is +/- 5%

    Am in need of two DC supplies for use in a car with our CF-28's and came upon this unit ($14. each plus $8. shipping):
    http://www.my-batteries.com/laptop-dc-adapter/panasonic-cf-28.htm#

    Anyone used one and have a review, please?

    I know that some of the cheaper "universal" supplies have been prone to failure in the past. This one is rated at 80W (I presume Output) which would be more than enough for a CF-28 (15V @ 4A).

    WDYT, please?

    Doc,
    With a little patience you can grab a Lind on eBay for around $20 shipped. They are built better than the Toughbooks!

    at that price, its gotta be worth a try. i don't get why they're advertising a universal P/S as something particular to a CF-28 though..

    Hey Doc
    I've tried 2 of those and both promptly died after a few weeks of use.
    I tore one of them apart after the last one burned-up and found the quality
    below par, one of the FET's had unsoldered itself ..probably why it self-destructed. When they die they smoke up quite a bit, usually there's a melted case involved too.
    If they used better heatsinks inside they may have lasted longer...
    I eventually sprang for the Lind. No problems so far, running it daily for 6 months.
    Regards

    Maybe this will help clear some things up.

    I called Lind tech support yesterday since my new AC/DC power supply was only putting out 15.3 volts. We talked for awhile about the power requirements and such. He said they have tested the CF-30 from 13 to 20 volts without any problems at all. He said they have a very robust power regulation in them. He said for me not too worry at all. I just wanted to make sure the piece was no defective at all.

    I'd say at 13v, it would pull more current, while if fed 20v, it would use less? The Macbook Pro monitors the input voltage and seems to stop charging the battery if it sees less than 15v. I'm sure all laptops do something similar... just that I can't bear frying my Toughbook, and the MBP was under warranty. :p
