I'm well aware of all you say, and have been so for a long time. It
wasn't a lack of understanding that was my issue, only my failure to
think about it. After all, I had the small inverter that I had been
using for years with my old machine, so it didn't require any thought to
plug in my new machine the same way.
However, there are a couple of things that folks should be aware of
before they willy nilly replace AC cords that have built in dc
converters. One is polarity (all devices do not use the same polarity)
and voltage (not all dc devices want 12 volts. One other thing to be
aware of is that not all the power cords that have the square body with
two prongs that plug into an AC outlet are converting the AC to dc. Im
not exactly sure what these cords do, but the AC is converted to dc
within the device itsself.
