You have to look at the device. If it's something like a computer or DVD player that operates on a low voltage (probably DC, but that's irrelevant) with an adapter, you have to look at the adapter.
In some cases the plug may be built into the adapter - the bane of power strip users the world over, as those adapters typically cover two or three outlets - but it's still important to understand that one is checking the adapter, not the plug.
Sorry, my quote meant to say "adapter" or "transformer" instead of plug. I'm going to update my post. The AC adapter/transformers/whatever you want to call them always have this information on them. Then what you plug them into is irrelevant. Most modern electronics are 110~240, but certain ones (my oral B toothbrush charger and Nintendo DS come to mind) aren't. Thanks for clarifying . . . wouldn't want someone to start a fire.
