This is a high quality AC to DC 'wall wart' which produces a regulated output of 12VDC at up to 600mA. These are switch mode power supplies which means the output is regulated to 12V (no more 14V outputs!), and the capable output current is much higher (600mA!).
These will power most projects that don't require more than 650mA of current. Center-positive 5.5x2.1mm barrel connector.
Works with 100-240VAC inputs.

Note: One of our shipments arrived with labels indicating 500mA. They are mislabeled and are actually 600mA.

The first one was not outputting the proper voltage but SparkFun replaced it, no hassle.
Price is right, Plug it in it simply works. What more could I want?
Excellent power supply both for powering my 12V-required projects as well as for hacking apart and using for other random projects. Have a few of these and definitely will be getting more.
It's hard to make a meaning review of a wall wart, it either works or it doesn't. I plugged it in and it delivered the promised voltage and made my project work. That's all I can ask for.
Very stable output, nice form factor, feels like good quality. I noticed it gave 12.4 VDC on no load.
Seems to work, hasn't gotten warm as far as I've noticed. Was a little annoyed that it has a red led that's on whenever it's plugged in, but you can put paint/tape over it.
Great product, keeps a steady 12vdc, replaced a cheap power supply that burnt up my led rechargeable flashlight charger because it went up to 16vdc and was supposed to stay around 12vdc.
It's small and takes up very little room. Also, a lot of my projects require an INTERNAL power supply and these units have a small screw to hold the cover on. This makes it easy for me to open and modify to remove the the 2 blades and rewire to my projects requirements. I have found that these units are very reliable and make good internal power supplies.
I already knew about the annoying red power led, not mentioned in your description, but from a reviewer. So i was prepared w/ strips of elec tape. Cords were a little on the short side. But a volt meter confirms A regulated 12v output, so all good!
After tab 'ing to my next line I lost the fun part of this story so I'll give ya the short.
Her cords have been so aggressively bent the shell has almost cut it, it reeks of some sort of China approved mold oil, and rattles like ball bearings in an engine.
Sparkfun is placing the quality of a $1 adapter in the $5 range sad to lose their trust here. Now I'm not positive to buy any non branded items from them.
While these are on the lower end of the quality and price spectrum for wall warts, what you're describing is definitely below our quality standards for this part. Please contact our technical support folks and we can make this right for you.
Working but off by 1.3 volts.
Oh, that's not right! Please contact our technical assistance team and they can help you with this.
i just recently finished an LED desk lamp project & used this 12v PSU to power it up. it works just fine. excellent. thx
