A little more research........the laptop's power supply is labelled for
use 100-240V, 50-60Hz and Toshiba says it will work without problem at
China's 220V, 50Hz supply.  Now, what about other things like radios,
curling irons, etc, you'd need a step-down transformer if you brought
these items from North America?  Is it better to just buy those sorts
of items in China?
