It is very compact and seems well made.
James A. Bowden
This is actually a _regulated_ switching DC power supply which consistently produces the voltage it is set for and runs extremely cool.
Dan
It worked very well, the adapter plugs fits snugly and do not come out even when you pull on them strongly.

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.

Small compact does not block other sockets on a surge strip unlike other products runs cool. Importantly one of the few adaptor that provides enough amps (1.5 amps) for high powered devices. Using it to run my cambridge soundworks.

I recently purchased this Vellemen universal AC adapter for some hobby electronics projects. Having been burned before with poorly made universal AC adapters (VCT VX-79NP - Multi-purpose Universal AC to DC Converter Adapter With Multiple Tips(1.5, 3, 4.5, 6, 7.5, 9 and 12V DC) - 1000mA), I was looking for something that actually gave the right voltage levels.

Using a multimeter, I checked the various voltage levels this adapter can produce and they all tested quite close to the advertised level. Unlike other cheap (and terrible) universal AC adapters (VCT VX-79NP), this one actually works as advertised.

Velleman Compact Universal DC Adapter Power Supply (PSSMV1USA).

This power supply is so handy to have around because it's so versatile!

Pros:
* Very easy to select different dc voltages.
* Comes with a good variety of adapter plugs. The pack of plugs can be easily attached to the cable using the cable's twist-tie so they're not lost.
* Nice design that allows you to configure the polarity (+/-) of the plug to meet the need of your device. Basically each adapter plug is labeled to indicate which way to use it.

Cons:
* I've noticed some line noise with this power supply. Most devices will have no issue. However, I have a particular scenario with an fm radio having a hum sound coming from the radio's speakers when this is power supply is plugged into the same outlet. I'm not fully sure it's an issue with the power supply or if it's an issue with the fm radio; but the hum sound only occurs when this power supply is used on the same outlet.

This is a great item to have on hand in any household.

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?
