So I should burden my product design, for a few million devices, to 
prevent someone from having an accident when they plug in my power 
pack to a different device that it wasn't designed for?

Also, a 1C diode would leave the power pack in a state that I 
couldn't use it in.

What else should I add in to all five million of my power packs, to 
assure that I have the right voltage output for his pedal?


I'm a great believer in "if it fits, it works, or at least it does no 
harm", but in the world of power packs, the damage was done when I 
was in grade school, by manufacturers who failed to see the need for 
and to establish a standard.
