So what happens if you power up a very hungry power demanding device ?
Do the cabin lights flicker?
Call and Warning lights flash over your seat - klaxon horns go off - customer
has exceeded power limits ?
Circuit breakers in the cockpit go crazy and one of the pilots comes back to
your seat with a nasty finger waving mode ?

-OR- simply nothing at all - your device is too demanding and a power supply
module just isolates you from the source.
Fortunately no bad burnt electrical ballast fumes emitted into the cabin.

Just watch it descending thru 10,000 feet as the power to your device is
cut off from its airplane source ?

So when is the booklet coming out "Cabin Power for Dummies 101" ?

Ouch ### ! Don't cut the black and white wires simultaneously !
The blue and red wires are for the Matrix !
And the green - you are Grounded !
