Oh yeah. Try to explain a "brown out" state to a
customer of a mobile data communication product who
decided to save some money and use the product with a
cigarette lighter adapter instead of installing it

Oh yeah, the lighter cord was too short so they used
an extender cable.

Oh yeah, they needed to power a second device, so they
used a Y-adapter.

15-feet later...everything "powered up", but worked
only for a short period of time before ceasing...with
all lights "on".
