I am using this with Panasonic Q - Game Cube
I am using this with my new DS ite and with Panasonic Q which I bought from Hong Kong last year it is staible all system which using 110V power and it is not make problem to my system like other brands.

Use this in the UK for the DS Lite
If you are confused as to which PSU to use for the (soon to be released) DS Lite, this is the ideal solution for the time-being. Use the pack-in PSU and this converter in the UK to charge your machine. Simple.

Works Perfectly
If you are planning on purchasing a Nintendo DS from Japan (perhaps for the colour option), make sure you grab one of these. You simply connect the japanese charger to this and then you can easily charge your Nintendo DS on a standard UK power socket. I just got mine this morning and its easy to use, works great and costs almost nothing! Go on, grab one!
