Velleman Compact Universal AC Adapter Power Supply Review

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 ;-).
