OK, I trusted some older posts and plugged it in - happy to say its working great and nothing burned :)
I have a model CUH-1001A saying at the bottom "120V 2.1A 60Hz". Working in Israel on 220V.
Can you specify the exact model you tested in the video and what it says on the rear side regarding the voltage?
I bought in US aunt model CUH-1001A. On the rear plastic it says "120V" only, and the manual for CUH-1001A specifications show also only 120V.
Is this the same model as you tested? If so, I can assume my internal power supply is 100-240V as in the tested unit, if not - I may have to buy a voltage transformer.
