Hehehe...yeah, I was thinking of getting the plug attachment in question, sticking it in the inlet in back of my portable radio at work...and wall mounting it!!
This "Targus" thing was a neat concept....however they forgot to keep in mind that plastic is pretty fragile...
Keep in mind you could probably still use the power-pack itself. Just attach a standard tape-recorder cordset to the inlet instead.
After all, the plug that is at fault here is essentially both ends of such a cordset, molded together without the flex in the middle.
This device was manufactured in the USA....what tax subsidies are paid?
