I bought it, sent it back because it didn't charge (used a regular USB connector), then plugged it into the Nikon socket the camera came with and now it will be charged. It looks like the Nikon P510 Coolpix is not compatible with any port for charging, strange but that's what I found. I hope this helps others as I almost got it back and would have had the same result with any other USB cable if I hadn't tried the Nikon connector first.
