Parts Express 3 VDC 500mA AC Adapter
Parts Express 3 VDC 500mA AC Adapter is rated 2.8 out of 5 by 5.
Rated 2 out of 5 by from DisappointedBought 16 units. Supposed to be 3 volt and marked as such. Turns out they are 6volt and I damaged 10 laser modules before I caught on.

Rated 2 out of 5 by from poor voltage regulationI got sloppy & assumed voltage output would be somewhere in the vicinity to stated value of 3 volts; I didn't measure it- till it burned out the miniature Christmas light bulb I'd wired up to it. These bulbs normally handle 2.5-3.5 volts, so I wasn't too concerned about level of control. But, it was actually putting out in excess of 5.5 volts. This is way poor. I'd spent quite a bit of time modifying a Christmas decoration to add lighting to it & the bulb won't be easy to replace. Now I still don't have an acceptable power supply.

Rated 3 out of 5 by from I thought it was a regulated voltageThe other poster is correct, it's output is not 3 volts. Without any load it outputs around 6 volts. Maybe it outputs 3 volts at 500ma but I would have thought this would be a general, i.e. regulated, power supply.

Rated 2 out of 5 by from Had high hopes but....I needed this charger as a battery replacement. Given that it's advertised as 3 volts, it seemed perfect to replace a couple AA batteries. I ordered two of the chargers and upon arrival threw them on my voltmeter to verify their performance. One was 6.1 volts, the other 5.8 volts. Pretty much double the represented voltage. Now I need to either wire up some resistors or keep looking...ugh.
