Do you have an old Nikon Coolpix digital camera? I bet you lost that super tiny, micro-sized USB cable that it came with, right? (Or is it a cord? Hmm, not sure– cord or cable, but it’s a connector yep). The model or type is UC-E6. And man, that is one tiny USB connector. Goes for roughly five bucks. As of this writing, I found several different ones all in the $4.50-$10.00 price range [Amazon, $4.66].
If you are also looking for the matching wall plug-in charger [Amazon, $24.98] (square-shaped, black and has a nice fold-up prong section) that you can plug the tiny USB cord into, it’s called the EH-70P AC Adapter Charger and can be found for $25.00-ish. That’s crazy expensive! However, I am thinking if you just have the cord, you could just plug it in anywhere with a powered USB port and skip the matching charger block:
“A Nikon Coolpix camera may be charged either by using the USB port to connect the camera to a computer, or by using the charging adapter.” 
Do you have the cord and your camera is still not charging? Maybe the battery shot. If you have had it stored in a drawer for over a year it may be totally gone. Do you plug it into your PC and it just blinks a few times and that’s it? Try the wall charger– I have found that for some reason, the wall charger works when sometimes your PC connection does not.
