If you want one of the hot new colours of DS Lite that is not available in USA or Canada, you might want to buy the Asia Region version. However if you do, you will need to buy a 3rd party charger for it, because the Asia version only comes with a Hong Kong version plug that will only work in 220V systems.
This compact charger saves you space and covers all voltages used across the world, and the plug type is for USA, Canada, etc.
