I have an opened but never used Kensington Ultra Portable Notebook Adapter. It plugs directly into your laptop via cigarette lighter or wall adapter. I purchased it so I could use my laptop while on the road but it didn't have an adapter for my a/c jack.

It has a bunch of adapters and what not. If you have any specific questions I'll be happy to answer them. It sells for $149.99, I'm willing to drop it for $70. I still have all the original packaging as well as the guide books.

Thanks,

Will it work with a dell? 4150 or 9200? DC (cig pulg) to AC correct? or 12v +

According to the paper work it will work with any dell that supports a 17 - 21 Voltage draw. In order to identify how much your laptop draws look on the bottom for a label that shows:

DC XXV
Y.Y A

Where X is the voltage you would need to show between 17 and 21 volts for this adapter to work.
According to the website the 4150 uses the N19 adapter and the 9200 uses the N19 as well. I do have the N19 adapter with the set. The unit also includes a USB powerport for powering cell phones, pdas, and any other device which can be charged by USB.
The unit itself plugs into the wall or into a cigarette lighter which doubles as a power jack for when youre on a flight. The unit produces 14 - 25 volts at up to 90 watts.

So this works from a cig lighter too then?

shoot me a email kcandiotti at sbcglobal dot net and I can send you some pics of it. It does have the cigarette lighter plug which plugs into the transformer.. then a wire comkes from the transformer to the device... at the end of the wire you attatch which a/c plug size you have... then plug that into the laptop. Kensington also promises a free laptop plug with every purchase so i'm sure you could take advatange of that too. My laptop only uses 11v so it cant be used with this power supply.
