Why not just get a step-down converter?

And then use a 220 to 100V (not 110V!) one Smile

I think a 110V model will do fine. I use this one myself. It works silently (another one I had was humming), and works with all Japanese computers I have (a Panasonic FS-A1ST, A Yamaha CX7 and a YIS503II). I have the 300W model which is plenty...

because I like to DIY stuff Smile and I do not want a supply between the supply Smile
Yes It just much simpler to get a step down converter but that is cheeting
