I understand that voltage in Japan is 100V.
According to the label of my camera's battery charger - which is the most vital piece of electric equipment for my trip - it works in the range 110V-240V (and 50-60Hz).
Will I have problems using it in the 100V network, or may I expect some tolerance?
With 'problems' I mean the battery charger exploding or not working at all; it's not a problem if it just takes a little bit longer to charge the battery.
The other battery charger I'll have with me (the one for my phone) clearly states on its label that it works at 100V-240V, so I'm sure this one will work - but this is less vital...
