Japan is 105V (Tokyo James...please correct me if I'm wrong). This kind of converter should also be relatively inexpensive.

A ccoupla things to watch for:

Using relatively expensive equipment, such as a laptop, with a cheap converter. Chances are, if a problem will occur, it will occur in the power supply module that you plug in to the unit (and not the computer itself). You may want to consider purchasing an extra power supply for your computer to take with you. If the worst happens, and your power supply module fries, it will be a PITA (and a lonnnng wait) to get one shipped abroad to you.

The other thing to watch for is hair dryers. Power converters/transformers all have amperage ratings as well. Since U.S. hair dryers typically pull a lot off amperage (amps

 

While Europe is 220~240V, their plugs differ. Also, some places are 220V 60Hz, some places are 50Hz which makes a slight difference in paper shredders (believe me, I know!) but I don't know if it matters for other appliances.

Asia is vastly different:

Japan: 100~105V; Kansai and Kanto have different electrical specs (50Hz vs. 60Hz, or vice versa)

Taiwan: USA standard, yeehaw! Whatever you buy in Taiwan can be used in the US.

Hong Kong: UK standard for obvious reasons, up to 240V.

China: 220V, but Chinese have recently adopted these nice adaptors for their plugs (3 prong) to allow any type of plugs to be used. Just make sure you have a small transformer for 110V products.

AUS/NZ: 220~240V. I say 240V because my AUS customers had some problems with their local electrical supply not being 100% stable.

All of my products for Europe/AUS/NZ are 240V +/- 10% tolerance to prevent problems, I would suggest the same for your transformer.

 

Thanks, everyone! I'll start shopping of rocnverters/transformers a month prior to traveling. I'll have fun for sure.
