Kensington 33362 Ultra Portable Power Inverter 150

If you need mobile power for your notebook, cell phone, digital audio player, GPS device, DVD/CD player, etc. then you have to get one of these items. It is very well engineered, and has a built in safety feature that makes sure your device will work before power is delivered to it. Be sure you plug your device into the power inverter, then plug the power inverter into the airplane's power jack, or your vehicle's power jack. That's it!

I don't have much to add to most of the other reviews I read before purchasing this product. No product is flawless and neither is this one: for instance, a higher power yield would't hurt.

But it does exactly what it's for, which is to deliver about 120W of continuous power. I tested it for the first time on an airplane trip 10 days ago. My laptop consumes slightly more than that with the wireless on and the NVIDIA card on, and as such, on my airplane trip the power was discontinuous. But actually, one shouldn't use wireless on a plane... When I turned the wireless card off and select the Intel graphics chip (it's a dual card Sony Vaio SZ680), power was continuos for the rest of the flight. Couldn't hear the fan of the power adaptor in the whole flight.

I liked this product just fine for the first year of use, but now the fan is so loud it's really annoying. When we're in the car we try to hide it under the seat because it's so loud. Too bad the warranty expired so I can't send it in to be fixed.

I bought this to use with my Toshiba laptop, because of the dismal battery life experienced with the laptop. It works perfectly. I've not had any problems at all.

I purchased this power inverter to use for business and pleasure while in my car. Works great with my Dell computer and Sony DVD player. It is compact and fits right between the seats in my car out of sight. I highly recommend this one, I got fast delivery from the vendor and it worked perfectly when I plugged it in.
