(The 5V regulator requires > 6.5V input to regulate properly.)</p>

I have a similar 5v supply I have been using for some time that has no issue with the same load and it's only rated for 250ma.</p>

Unscrew that and the case just comes open. If you look closely in the picture above, you can see the recessed hole for it to the left of the prongs.</p>

Is it a "crack it open and glue it closed" situation, or actual screws to open it up? The unit I have now is one of block styles with 4 screws to open it up - very nice, very hard to find in the 5V-1A output range.</p>

Plugging a 2.5mm plug into a 2.1mm jack might work, but it can result in an intermittent connection and should be de-rated as to it's power handling capability. You can check to see which type of connector you have by measuring the inside diameter of the plug; it should be 2.1mm or 2.5mm in diameter.</p>

Instead of a household plug on one end and a barrel connector on the other, just put screw terminals to allow to to tap AC power in one side, and headers (or something similar) that output DC on the other side.<br>
This would make it easier to build devices that don't require an external AC adapter. We can just attach a length a cord that plugs into a household jack, or otherwise connect to AC, and the self-contained project will have power.</p>

When I opened it, I noticed that one of the wires that connected the AC prongs to the PCB had broken off at the soldier joint. It's a fairly small gauge stranded wire that's used for the connection. After stripping it back and resoldering, it's been working great ever since. While it might not be the best quality wall wart, fixing it should be a cake walk for the typical Sparkfun customer.</p>

So all you need is a barrel jack. Just make sure to get the right size barrel jack (2.1mm).<br>
Ya might want to get two of these while you are at it, because they are not the best quality available and do have a relatively high failure rate.</p>

I ordered 2. The first one was Dead on Arrival.<br>
Installation instructions:<br>
1) Plug into wall<br>
2) If no red light on power supply throw in trash<br>
(Confirmed no output voltage with DMM)<br>
Not worth shipping to try to send it back.<br>
The second unit appears to work.<br>
Output Voltage is 5.24V.<br>
Switching frequency is 100kHz (about 100mVp-p switching noise on scope).</p>
