This adapter (PSSMV1) is _exactly_ what I was looking for. This is actually a _regulated_ switching DC power supply which consistently produces the voltage it is set for and runs extremely cool.

I recently had a portable voice recorder fried by a Coby "universal" AC adapter only to discover that it delivered a much higher voltage than I set it for. For light loads, such unregulated universal adapters will deliver more voltage than desired potentially damaging electronics that don't have (enough) over-voltage protection built-in. Upon checking with a meter, I observed an output of ~10V with the voice recorder attached instead of the 3V I set it for.

Even with no load attached, the Velleman compact switching DC adapter produces exactly what it is set for. The next time I have to replace another AC adapter, I will be buying another Velleman compact switching DC power adapter (and will likely even pick up a spare before the need arises ;-).

When the power supply of my Linksys wireless access point unexpectedly died I bought this one from Welleman to replace it.
I am extremely satisfied, this power supply is far superior to any OEM supply because it is electronically regulated: the voltage you set is actually the voltage you get (some OEM power supplies have outputs up to 70% higher than the intended voltage).
Also, this power supply does not heat up (again, because it is electronically regulated), and therefore less likely to overheat and fail.
One word of advice, though: I recommend putting some tape over the voltage selector in order to avoid any accidental voltage switching, which can be deadly for the equipment connected to the power supply.

If you have a DC power adapter which starts buzzing and making noise - that means it is failing and it needs to be replaced. This seems to be a pretty well-made, universal replacement for most DC adapters. It doesn't seem shoddily made, and so I'd expect it'll last a good long time.

The most important thing you need to know is that there is really no such thing as a truly "universal" DC adapter. So while this will probably work for most people in most applications, if you want to avoid disappointment, do yourself a favor, and take five minutes to answer the questions below. All this information SHOULD be on the back of the DC adapter you are replacing, although it is often in painfully small print and difficult to read.

(1) Does the voltage on the old adapter match one of the settings on this new adapter? (6v, 9v, etc.)

(2) Can you tell which part of the tip of the old adapter is carrying positive voltage now? Most, but not all adapters should have a little diagram showing you which part of the tip carries the positive voltage. If it isn't on the adapter, the diagram is sometimes right on the device itself, showing what needs to be plugged into it. If you can't figure it out, you have a 50% chance of sending the power down the wrong side of the tip, which could conceivably just fry your device. And no, nobody but you is going to pay for fixing the thing you killed by setting this up wrong. So it is pretty important to figure this out and get it right.

(3) Does the existing device need less than 1.5 Amps of power?

DISCLAIMER: I did not order this because it does not have adequate current output for my device. However, I am taking the time to write this review because this adapter seems to be inherently better than similar supplies I have seen and used. If it were adequate, I definitely would buy it; The three stars is my attempt to be neutral, because the problem I had wad due to Amazon's failure to publish all (any!) necessary specifications. I have listed these at the end of this review.

Looking at other reviews, I see many serious problems being reported which are likely due to unfamiliarity with these units. Even if one is familiar with electronics, Amazon's listing as of 1/21/2014 fails to provide information that is necessary to decide if this adapter is actually usable! Here is what you need to know:

1. This adapter can be plugged into a U.S. 110 to 120VAC receptacle, but with a suitable plug adapter will work safely on 100 to 230Vac service just about anywhere in the world.

2. This unit can be set to deliver 3, 4.5, 6, 7.5, 9, or 12V DC output. This is not listed. Note that 5 volts is not available (the 4.5V setting MAY work). In general, using a voltage setting other than your device specifies can damage it.

3. Output current is limited to 800mA in regulated mode (output voltage controlled accurately); It can deliver as much as 1.5A (1500mA) max, but you lose the accurate regulation. Few similar adapters regulate voltage, so this is probably OK. If the output current rating of the adapter is HIGHER than your device's, that is fine. But if it is LOWER than your device's, operation may be unreliable, if the thing works at all. And some devices can be damaged. Amazon MUST list the current rating!
