Answer Title: Can I take my digital SLR camera overseas on a vacation?
Answer Link: http://support.nikonusa.com/app/ans...

We don't sell the cord separately from the charger at the Nikon Store.

That's the AC wall adapter latch. Please see page #21 of the user's manual for the D7000 for more information.

We do not recommend leaving the battery in the charger once is fully charged and that will only take 1 hour and 30 minutes.

You are welcome to send your unit for evaluation with the copy of the receipt of purchased.

Yes, all Nikon Coolpix cameras have an auto switching (from 100v to 240V 50hz/60hz) battery charger that will work in most countries around the world. AC adapters have similar characteristics. Always check the specification plate on your other battery chargers or AC adapters as third party products may not support dual voltage systems. We do not suggest the use of third party battery chargers and AC adapters with Nikon equipment.
Note that the power cord included with some Nikon chargers or AC adapter is designed for 110 volt use only. A power cord suitable for the local power system should be obtained on arrival, most airport shops and computer suppliers will carry these items which are typically used for laptop computer power supply connections. Be sure that the new cord you buy fits the Nikon adapter you wish to use it with and that it is rated for the voltage in your new location. While not recommended, a simple plug adapter may be used, but caution should be taken as the cord Nikon supplies is not rated for the higher voltage and may heat or fail.
