AC Power - Running your digicam off the wall outlet power rather than by battery power. Usually means purchasing optional AC power adapter.
AC Power - Alternating Current which is used to operate your digital camera directly from the mains supply rather than a battery. Sometimes supplied, but normally requires additional expense.
Without AC power, not only would modern power distribution be nonexistent, we wouldn't even have plug-in-the-wall electronics, since without transformers, we wouldn't be able to step-down power line voltages to working voltages inside our TVs, ...

AC adapter
Some digital cameras offer an AC power option as well a battery option. AC adaptors enable the user to plug their cameras into electrical current for power, when not in the field.
AC/DC refers to changing between alternating current (AC) and direct current (DC). To switch from AC power to DC a transformer can easily be used to regulate the current. Power inverters convert DC current to AC current.
The essential features of the apparatus are a high-voltage AC power supply and an electrode-insulator-object assembly.
There are three basic types of external flash units considered here - standard hotshoe flashes, handle flashes and macro flashes. (as noted above, studio flashes of the kind that require household AC power are not discussed in this document) ...
TLA480 (GN 48) - Bracket-mounted flash system requiring external Power Pack PS-120 for operation.
RTF540 (GN 40) - Bracket-mounted system with slaves, coloured panels, AC Power Unit, High Voltage Battery and standard Power Pack sets.
This is what I do when I don't have access to AC power and just want to do the minimum amount of backup work each day. I use BackUp MyPC from Stomp (based on Veritas technology) or the built-in Windows backup, but there are plenty of other solutions.
