Posted on Tuesday, September 19th 2023 by Spider_fanz to r/retrogaming | Question | 2 pointsI need to power some Japanese consoles in Australia where our power standard is 240 V can anyone recommend a good stepdown transformer

For any console that has an external power supply, it is much simpler to just get a regular PAL power supply for that console.
The only consoles where you would actually need a step-down converter is for the Saturn, Dreamcast, PS1 and Phat PS2
If the console already has external plug adapter just get a 240v plug for it
Some chance the Japanese power supply can tolerate 50 Hz. My US and Japanese PS2 OEM power supplies have 100-240V, 50-60 Hz printed right on them so they're universal but don't assume 50 Hz is a good idea if only 60 Hz is printed.
You're in a bad spot for Sega Saturn and a few other consoles with internal power supplies. Very convoluted but you go power outlet -> car cigarette outlet adapter -> 12V or 24V DC car cigarette power supply -> DC to 100V, 60 Hz AC converter you buy from Japan. Amazon Japan accepts my US credit card.
Be careful with that approach to have some overhead in watts and va since you lose 10% or so power each from AC to DC and from DC to AC.
