The good thing about this charger is that you do not need a New 3ds XL to use it per se - the "dock" separates from the plug which is the correct size for plugging directly into the console. This is the same plug for all 3ds units and even the DSi. Additionally, this plug works like most power bricks do these days - meaning that it works with different electric input levels. This means this plug will work in other parts of the world (with an appropriate adapter), unlike the official Nintendo one. I've seen some people concerned that this charger has a slight difference in voltages from the official unit, but after considerable research I haven't found any evidence of this being an issue online. I have personally used this charger as well without issue.
