For small (say under 5 Watt) loads the old wall wart has bit the dust 
(at least in California) because they waste power.  The new wall warts 
don't use mains frequency transformers, but rather transformers running 
is kHz frequencies.  You can tell because they are much smaller than the 
old ones and much lighter as well as working on any mains voltage and 
current in the world.

Have Fun,
