Universal Dc Adapter Review

My universal DC adapter worked as advertised. The main issue is that it has a tendency to fall out of the cigarette lighter when barely touched.
The important thing with this and a universal AC is to read the instructions. It is not as simple as finding the 9V adapter piece and putting it into the slot. You must determine the polarity of your product by looking at the (-)---C---(+) on it. This determines which way to connect the adapter together.

UNIVERSAL AC DC ADAPTER ADAPTOR SONY 1000mA 1.5 to 12 V Review

If you are looking for a sleek power solution for your battery powered devices that looks like an expensive accessory and goes with your decor, you will be vastly disappointed with this device. It's an ugly device that is a bit bulky.
BUT if your goal is to pay a low price for a device that allows you to run a whole range of devices of various types and voltages for under $10 dollars then this is for you. It does the job and it does it well.
At a time when money is tight it's a bargain and a half, so if this is what you need then go for it!

500MAH Universal Ac Adapter Review

500MAH Universal Ac Adapter
Average Reviews:

Plenty of tips are provided to allow the adapter to work with almost any low voltage piece of electronics that allows a transformer to be plugged in. The switch to set the output voltage is on the underside by the plug so is not accessible when the unit is plugged in; this is great since it means the voltage can't be accidentally changed while it is in use. If there was storage for the extra tips directly on the transformer I'd give it 5 stars.

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

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

Universal Ac Adapter Review

Universal Ac Adapter

If you have ever misplaced the AC adapter for an electronic device, you'll wish you had one of these around the house.
It comes with 12 different plugs, so odds are very good that one will fit just about any device. The polarity can also be change from + on the center to - on the center for 'non-standard' items. Of course, the down-side to the 4-way adapters, is that there are 3 unused plugs sticking out in all directions. A little awkward, but in a pinch, it's better than nothing.
There is also a voltage selector switch with the options of 1.5, 3, 4.5, 6, 7.5, 9, and 12 VDC. That should cover almost every option.
The 300 mA output current is sufficient for most electronics.
The one thing that is missing is a 9V battery eliminator plug.
