SECRET HACK: Instead of using this cable for what it was designed, why
not use it to convert some of your extra PC power cables into extension cords?
With this adaptor, any desktop or monitor 3-prong power cord can become a regular
110V extension cord. Convenient!
Remember back in the eighties and early nineties, when computers drew power
from the wall and monitors drew power from the computers? When desktop power
supplies had both male and female 3-prong outlets, one for power in and one
for power out?
No? Well, believe it or not, that was a thing, and the DataPro 9229-series cable
is a computer power adaptor that harks back to that era. This cable was designed
to convert wall-plugging monitors into computer-plugging monitors, because yes,
that was desirable behavior back then.
Nowadays, computers draw so much power and monitors do as well, it's highly unlikely
that you'll come across any desktop power supply that offers a piggyback power
port. And even if you did, we wouldn't recommend using it before doing careful research
into the power consumption loads of all the involved devices, lest something go awry.
