No offense meant, but you have it entirely backwards.

Assuming that there isn't an explicit problem (eg. the
object-to-be-powered has a short or will otherwise consume excess power)
the VOLTAGE is all that matters, assuming that the amperage-capacity of
the power supply is accurate.

You can run the tiniest 12V-nominal appliance from the hugest car
battery.

What Doc did is perfectly reasonable. And even if the JetDirect develops
a dead short inside, the new power cube is only 20% more capacity,
hardly increasing the fire hazard (more than appliances already are :-)
