I’m living in South Korea which has a 220v 60hz power standard (with a euro two pronged round pin plug)

If I buy an Asus RT-AX82U domestically in Korea, then it’ll cost me around $300.

However, some of the major shopping portals here are importing the Chinese model and selling at $130 (its legit, I checked).

As it’s the Chinese model, it comes with a ‘US style’ flat pin plug, and is rated for 220v 50hz (which is the standard in China).

Now for the question:

I could use a plug adapter which would convert the frequency…

…but to be more elegant, can I just get a Korean Asus power supply and plug it in directly, or would that 10hz difference screw it up?

TIA
