Mel, some small electronics will charge off the computer USB.
My Sansa MP3 player does this. It depends on what the small device IS. My digital camera will NOT. If the smart phone has a USB plug, then it might also.
Smart phones will sync with computers. That is also for downloading stuff into the computer...data or photos.
My old Nokia phone does not charge thru the computer USB.
Only with a car jack or electrical plug.
