Can a power adapter be built with batteries and a 110 power converter to power a battery powered flash or camcorder?

The idea is to take 4 AA 1.5 volt batteries that power the flash and wire them together. Then wire the 4 AA's to a 6 volt power adapter so I can plug it in to 110 volt out let. Thus making my flash hard wired.

You can do it like that, but you don't want to leave the batteries in, or they would constantly charge and possibly explode. You want to apply the correct voltage directly to the terminals (sans batteries). Most appliances that take batteries also have a plug hole for inserting the correct power adapter.
