Really gone off-topic by now, but this is quite interesting. I guess that's why we are now told that removing those wall adapters saves electricity.
1. Still, I don't know if I should fear plugging my mate's Miggy to a PSU that outputs 14V.
2. On the other hand, I've tested one of mine, which feeds an A500 with power since 2 years, and I was quite surprised to find +4.88V / +11.6V / -16.2V (that was tested unloaded, though). Maybe it could explain the vibrating noise this PSU sometimes does...? Should I feel concern about this?!
