can we charge battery using usb cable for nikon camera s200?
No you need the charger that comes with the camera. There are device that you can use the usb cable to charge, like an iPod or iPad.
If you are missing the proper cables and charger then you will need to get another one. Below is the link to the Nikon website which can be of assistance.
Hope this helps.
