Do I need a transformer to charge my camera overseas? (England, France)?

I have a Casio Exilim S600 digital camera, and am planning on taking it overseas to England and France. I bought grounded adapters for both countries, but the pamphlet that came with them tells me my charger needs to be dual voltage and say AC Input 110v/250v 50/60 cycles.

Mine reads:
AC ADAPTER/ INPUT: 100-240v 50-60Hz 83mA
OUTPUT: 5.3V 650mA

Does this mean I need to buy a transformer?
If yes, could you link me to an example? I'd like to know price range and where I can buy one.

Thanks.

The answer is right here:

100-240v 50-60Hz

All you need is the adapter so your charges plug will match the wall outlets in the country you are visiting. The charger works with any of the listed voltages. Most electronic stores sell kits for under $10

You probably will plus plug adapters and surge procwtor. Alot of over seas power is higher then our 110v plus their plugs are different. So i would suggest u get all 3 things so you won't have a problem.

Since the adapter is rated for 240v @ 50Hz, you won't need a transformer, but of course, you'll need those adapters.
