Do a search on this string:
"Panasonic TuffBook AC Adapter NR BUY"
This should turn up multiple auctions. I won my action at $20. It looks like current auctions are going for more (~$45). Shipping is expensive at $9.50 so factor that into your bid.
The ad for my auction said the adapter was for a CF-25. There is another guy that is selling an adapter which may also work. Search for this string:
"MEGA Panasonic ToughBook AC Adapter + FREE"
You could probably win this at the starting bid of $35. I do NOT know if this will work. It looks to be bigger than the adapter that I bought. Shipping on this adapter is even more expensive at $15.00.
There may be other auctions that have adapters that work. Any of the Panasonic adapters at 15.1v and at least 2.6 amps should work fine.
There are also quite a few Toshiba and Compaq A/C adapters that can meet the voltage and current requirements. However, these will not have the "panasonic proprietary" plug. I have been looking for these plugs/jacks with no luck. If we could find these plugs a whole world of cheaper adapters will open up. If you know of where to get them please reply here.
