Terry, I would seriously suggest that you contact Nikon support. Give them a call and inquire about this. They're very friendly and knowledgeable folks there.
Just a few doing a google search.

Heading to Botswana in September for safari and wondering about charging Nikon batteries. The charger says "100-240V~50/60Hz"....does that mean the charger will take the 220 V that is in the camps??? I realize I will need to get an adapter for the prongs, but hopefully not a converter? We can only take 20 kg (44 lbs.) of luggage per person total, and I don't want to waste 5 lbs of that on a converter if it's not necessary. Thanks in advance for any advice you can give!
