Yes if you deal with a lot of these wall warts sooner or later they are 
going to come back and bite you in a tender place.
what I suggested was a good power supply. Astron and pyramid are both 
good manufacturers. These are not "power adapters" in the sense that you 
are probably thinking about. they are square boxes that have the three 
prong power cord and plug into a wall socket. On the supply itself are 
two terminals that will allow devices to be connected.

The output is generally set at 13.5 volts dc (+/- 10%). The cheaper ones 
have a little trim pot that will allow you to do some adjustment on 
that. The more "advanced" (more bucks $) will have a front adjustment 
with meters and such to indicate volt/amp levels.

Not all devices are created equal.
Before you do anything take a look at the wall wart or device to see 
what levels it is expecting. small devices might only want 5v or 9v 
while something larger may want something along the lines of 12v to even 
48v. (most consumer level devices look for 12-13.5v dc).
