120V to 100V Voltage Converter 500watts Step Down toroidal Voltage Converter for Japan appliances Used in US［CE, CQC Certified］

I use this https://a.co/d/01o1MvDG for both my Celebrity II MD-7000 and Sony MDS-S500. Works great no other issues.

The most attractive possible voltage converter. https://www.amazon.com/dp/B07L56PYZS Now, that voltage converter has two outputs, and it feels like a waste to not use both of them ... I wonder what I should get on Mercari next ...
