Kensington K38037US Auto/Air Power Inverter with Two USB Ports for Mac or PC Review

Average Reviews:

(More customer reviews)This is my First Inverter Purchase.
I was surprised at how small the Inverter was when I received it.
I uploaded a few pictures to show the size next to an iPhone and a US bank note.
My laptop power draw is only 65watts(HP Compaq nc6400) and the Inverter was able to power my laptop and an Iphone at the same time just fine.
For Airplanes:
First and foremost, before flying and purchasing one of these Inverters, make sure the plane you are going to fly on has DC or emPower. Some planes already come with AC power built in.
The following is a great website with a ton of useful information about power and flights:
seatguru(dot)com
I purchased this Power supply thanks to the recommendation from the seat guru website.
I took a trip to Dominican Republic on a smaller American Airlines plane, which had DC power.
The Inverter worked liked a Charm. It kept my battery charged for the entire flight of 2 hours from Miami.
I will be taking a trip with American Airlines(777 with DC Power) later this year, and I will update the review once I have used it on a LONG(14hour) flight.
UPDATE JULY 2010:
I used it on two 14H AA 777 flights. ( NYC to Tokyo NRT and back).
It worked just as advertised.
The plane power port did flicker on and off through out the flight.
So every 15min my computer would indicate that I was running on battery.
But this was not an issue with the inverter, it was with the plane.
It kept my laptop and ipod charged for the duration of the flight.
The Inverter works like a champ and I still highly recommend this Inverter.

Kensington K33197 120W Auto/Air Ultra Portable Notebook PC Power Adapter Review

Average Reviews:

(More customer reviews)This is the perfect adapter for me as it powers both my notebook and all of my gadgets from a single brick. I use it for my notebook, DVD player, cell phone, mp3 player, guitar trainer and PDA. The Kensington is simple, compact and lightweight without a lot of fussy extra stuff to deal with. The iGo and Targus systems require a separate dongle for low-power devices like cell phones and CD-players.
"Brick" really isn't a good description though, because the Kensington transformer has a super slim profile and is lightweight. I bought the 120w version because some people reported trouble with the 70w on newer HP Compaq Business notebooks. I figured the 120w is good now and insurance against obsolesence in the future.
The power supply is just part of the picture though, as the real beauty of the system is the "smart tip" feature. I frequently fly on international and long haul domestic trips and like to take along my portable DVD player for entertainment. Instead of hauling heavy auxiliary batteries or having both a DC adapter for the plane/rental car AND the regular power bricks, cables and wall warts for AC, now all I need is a single power supply and the right tips.
It seemed like I was always forgetting to pack the one crucial component I needed, like the USB cable to charge my Tungsten T or the wall wart for my mp3 player. With this system, everything stays in one pouch in my carry-on briefcase and the OEM power supplies stay at home, no more sharing and forgetting....
On the downside, the AC power cord really needs to be longer. Now it hangs down off the wall with the weight of the brick straining the cord. This will eventually lead to failure and an electrical hazard unless replaced. Also on my wish list is a separate European two-prong power cord to eliminate the need to pack a plug adapter.
Technical support is a joke, as the call desk didn't even know that any of the DVD tips were available. Technical spec information is nigh on impossible to get. My DVD player wasn't listed on the website and I wanted to know which tip supplied 9v.
Good luck trying to find that out without a major research project. I wish Kensington would just publish a compatibility chart on the site and keep it current, instead of that goofy query-based tip selector. It is so out of date, that it doesn't list many of the DVD player models that have tips (e.g. Panasonic).
I wanted to find the right tip for my Philips PET1000 DVD player. I finally had to go to the manufacturer websites that Kensington makes tips for to dig out which one uses 9v (it was Panasonic). Bought the tip, works like a charm. This works for other devices that aren't listed too, like my Tascam gutiar trainer. If the tip fits your device without forcing or isn't loose, it is probably the right one. However, ALWAYS check the voltage and amperage first to avoid frying your stuff.
The bottom line is that this is head and shoulders above the other AC/DC systems out there. If Kensington can keep up the product support by making new tips for gadgets as they hit the marketplace, it could be around for a long time.
