Oh poo. How sad. I bet you know what an ohnosecond is now!
It seems to me that part of the problem is that there is no standard for low-voltage plugs. A given plug and socket size can be carrying anything from 3V to 24V. It's an accident waiting to happen and it's only luck (well partly luck - partly paranoia) that I haven't let the magic smoke out of something or other around the house. It's a real anomaly. Mostly you can't connect the wrong things together because the plugs don't match (eg 10A mains vs. 15A mains vs. 20A mains or USB vs. SATA vs. HDMI vs VGA).
Troy, all is not lost! You can easily get the magic smoke back in for far less than what QSI is charging.
