Does your project need a little more umph than our wall wart adapters can supply? Why not give this a shot? This 2A “laptop brick” supply outputs both 5V and 12VDC and is terminated with a 4-pin Molex connector.
The Molex connector is a standard 8981 Series Power Connector, like the disk drive connectors in your PC. Adapters and Cable assemblies are easy to come by at computer supply stores (also, check our related items) so you shouldn’t have any trouble getting your project powered up.
To plug the brick into the wall you’ll need an IEC C13 cable. You know, the AC cable from your computer or your guitar amp, don’t worry we sell them too, check the related items.
The mating connector is part #: WM6988-ND. We don’t sell it but it’s commonly found.
Note: Only the pin next to 5V is grounded. The pin next to 12V is not connected (NC). Please refer to the picture of the bottom of the unit for more information. Also the AC cable isn’t included in case you have one laying around or you’re outside the US and will need a different mains plug.
You can try using a terminal block [ https://www.sparkfun.com/products/13061 ] or 2x male DC Barrel Jack Adapters https://www.sparkfun.com/products/10287 for the laptop power supply’s output. If you are using both 12V and 5V, you may need to strip some wire and connect the GND pins together. Also, make sure that the wire that you are using can handle the amperage [ https://learn.sparkfun.com/tutorials/working-with-wire#wire-thickness ].
Unfortunately, we do not sell the Molex connector [ https://www.sparkfun.com/products/retired/11300 or https://www.sparkfun.com/products/retired/11297 ] in our catalog anymore. You would need to go to Digi-Key, Mouser, or Newark for the connector. You could also make some sort of adapter and splice the wires together for the output.
The power cable [ https://www.sparkfun.com/products/11299 ] for a US wall outlet is sold separately.

30ma load and 5v supply dropped to 4.1 volts Didnt try 12 v as 5 v was power for PI and it choked
That seems odd, and very out of spec. I would suggest contacting our tech support team, they should be able to help resolve the issue.

Meets my needs but I’m not pulling much current. I just needed 5 and 12 volts in my project. I would have given 5 stars if it wasn’t for the short cord.

I originally was going to comment that this was “OK”, but that it was yet another Sparkfun product lacking a power cord and that I was disappointed. Then the Review title couldn’t be changed from “Best Thing I ever Owned!”, so I’m downgrading it to “Bad”. I probably won’t use them because it is more trouble than it is worth to search around in dark corners for unused power cords and I feel suckered and probably won’t use them
Bought a one from a Chinese supplier that was rated to deliver 2A at 12v/5v - cheaper, but it was junk, shorted out at about 1A. this works great, and as labeled and rated. thanks Sparkfun, a quality supplier.
Perfect for isolating power related issues on a complex repair
