I've found airports to be the best at such adapters. About the "cord". ALL cords I have use a 600 or higher volt rating cable or wire. So 240V on said cord is just fine.
You may be over analyzing.
I have a Nikon D80 and the MH-18a battery charger (I think that's the model #). I live in the US, but will be traveling to Africa where the electricity runs at 230v.
Now the battery charger itself is fine, but the power cord is only rated for use in the US.
The Nikon web-site suggested picking up a power cord when I arrive in the airport. I'm not sure that I want to take a chance that the airport will have what I need. If there wasn't an appropriate store, or it was closed, then I'd be screwed. I'd rather be all set ahead of time. Nikon's customer support has not been very helpful either.
I tried doing a search for power cords rated for 240v, but it's hard to find anything easily that way.
So... here's the question. Can anyone help me in finding the correct power cord. Another thought would be using a voltage converter. It sounds liike that should let me safely use my set up.
I know that I will also need a plug adapter - but those seem easy to find compared to this.
