Kensington Lightweight, Slim line 120 Watt AC/DC Mac or PC, Cell Phone, DVD, PDA, or iPod Power Adapter (33197) review:
5 stars (Compact and Useful!) - I have a high powered laptop, requiring 120 watts. This was one of the few "third party" adapters that I found capable of powering this monster. It works well with my HP power hog, and also powers my smaller, more portable Dell laptop. I have used it at home, hotel rooms, and in the car. I've found it convenient and useful.

As another reviewer noted: I hoped it would also power my cell phone and Dell Axim, but no luck. Kensington could sell more adapters to make this product even more useful.

Another upside was it was $20 cheaper than the OEM HP adapter for home and auto. I would buy it again. It had alot more wattage than the igo, another option.
5 stars (extra slim AC/DC & DC/DC laptop power adapter) - This is an extra-slim unit so it is the best laptop adapter that I've seen for traveling. It can take auto or air DC input (see below). It is rated at 120 watts so it handles my 90 watt Dell Inspiron 8200 nicely. This unit even powers my HP zd7000 with 17 in screen. This is even though the HP AC adapter is rated at 135 watts. Note that the HP zd8000 17 inch screen computers are not listed in the Kensington compatibility booklet, so I can't vouch for those computers. This unit features innovative built-in cooling fins that are embedded in the plastic case. This means there are no holes in the case so if you spill any liquid on it (not recommended), you have less chance of getting electrocuted. This unit is meant to hang down from the wall AC socket via a very very short AC cord. Do not lay the cooling fins on a rug or flat against any surface - you might cause overheating. The unit comes with 7 tips for a wide range of laptops, plus an iPod tip. It has a cool blue "On" light. It comes with an alternate cord for plugging into a standard automotive 12 VDC negative-ground socket. The alternate cord also has an airline in-seat power plug. I had a problem with a different model Kensington AC adapter, and their tech support does answer your emails and solves your problems.
3 stars (Preliminary review) - This is based on a couple of days' experience.



The AC seems to work. Haven't tried DC yet.



It's lighter than the factory power supply for my Compaq Presario 2100. That's 18oz; this one is around 13oz without the DC cord; even with the DC cord it's a couple of ounces lighter. It's also a bit slimmer, though wider and a little longer.



It has built-in velcro straps on the cable. Cool, means I don't have to add my own.



The cabling is kind of interesting. The AC input cord is only about 5" long, so the power supply normally just hangs from the outlet. The DC output cord is about 10'. Both cords will detach from the PS itself, and then the DC output cord connects to one of several tips that select voltage and tip style.



The advertised capability to power almost anything is quite attractive, but I wasn't able to find anything about alternative tips at Kensington's web site. It'd sure be nice to be able to power my PDA and my cell phone, but they'll take unusual tips. Their compatibility page had lots of laptop computer coverage, and zero coverage of anything else.



When you combine the tip with the connector on the end of the cable, the result is about a 3.25" rigid connector sticking out the back of the computer. That make me nervous; it seems like it's asking to get broken or, worse, break the laptop. It may interfere with one of the major things I wanted this unit for - strapping the laptop to the center console in my motor home. A right angle connector would be better. The factory power supply has a right angle connector, and projects only 0.75" out the back.
