I bought this package simply to get the charger after learning my brand new camera came with one of those horrible chargers that requires a long cord. You know, the kind that can attach to either the charger or to the camera itself. I do not want or need another darn cord slithering around and wrapping itself around something inside the camera bag. I love these with the attached plug that swings out for use and then tucks in for storage. I doubt I will ever use the car charger or the converter that comes as part of the set, but the extra batteries are a nice bonus and they seem to be every bit as reliable as the more expensive ones from the manufacturer.This is actually the second one I bought because the first one didn't want to give my battery back when it completed the charge. I noticed several other brands from differing sellers that looked identical to that one but I didn't want to chance that they might have all been produced in the same factory and simply had a different logo printed on it. This one looks similar, but not identical, and it works exactly as it should; easy to click the battery in place and easy to pop the battery out when charged, plus an indicator light to let you know when that is! The lesson I learned here is to purchase my camera accessories from someplace that specializes in camera accessories, not someone who sells stuff for any and all kinds of electronics. Oh,
