Yes, The Charging Unit is Dual Voltage - 110v-240 50/60Hz - You would only need to get an adapter plug for the country you are going to be in when you need it. If however, you plan to try to hook up the camera video output to a television- remember that video output is only NTSC (Standard US) and NOT PAL or SECAM This usually isn't the case for most people, but often goes with the question of dual abilities..
The instruction booklet says (on page 6) "In the U.S.A. and Canada, the battery charger must be connected to a 120 v AC power supply only. When connecting to an AC supply outside of the U.S.A. or Canada, use a plug adaptor to suit the AC outlet configuration." Panasonic's toll free number is 1-800-833-9626. They might be able to give you a better answer.
Yep...it's dual voltage range (110/220 V), and 50/60 Hz. I just checked the back of the charger this morning. But you'll still need a plug adapter. The prongs are for standard US-Canadian, not European/Asian.
The battery is only 3.6VDC and the charging unit works since 110VAC until 240VAC automaticaly, you don´t have to do anything, put at the outlet and the unit lit the green led showing that the battery is in charge. When its finished the led stops lit. Panasonic could be change this look, when something is in charge, the led will be in red condition, like my cellular. Great câmera, beautiful pictures, I took some pictures at no light in my street, only the cars passing in front of my house, DMC-FH25 works perfect, like an old Minolta I had.
Be careful with the "scene settings". The camera has an abundance of them. Pets-Night Scene-Party-Portrait. You might want to experiment with them so that when that special scene is there, you don't get caught off-guard.
