What to pack for Japan
- No plug adapter: your U.S. plugs fit.
- A small U.S. power strip, so one outlet charges everything.
Check the label first
Look for the input line on your charger or device. INPUT: 100–240V means it works anywhere with just a plug adapter. A single number such as 120V means it only works at that voltage.
