The power supply unit keeps its promises and brings even more. As described one GBA / DS, DS Lite and DSi / XL in 220V and 110V load (appropriate plug adapter abroad (eg Type A provided in USA)) without any problems. What the description does not yield, but should give up, is the fact that you can charge compatible devices at the same time! We use the power supply both in Germany (220) and at the moment in Japan (110V) to our DSlite and recharge our DSiXL same time, or to provide the same when playing with power.
