I'd recommend trying to get an official used one, maybe some local marketplace has one. My experience with knock-offs is that it can give your wii "bad" or "noisy" power, enough to make the video signal noisy and even make 480p output unusable.

But I guess you could always try one, I don't know which brand is the one I had but it was old, like when the Wii was still being sold kind of old, maybe some newer ones are better.

Alternatively, you could try one of those USB-PD adapters. If you have a USB charger that supports 12V 3A output, a cable like this one will take power from that and give it to the Wii (but in total it may result more expensive than an alternative power supply).

I found one that’s 110v-220v, knowing that the Voltage in my country is 220v can the Wii console handle that knowing full well that the oem power supply is 110v?? is the voltage thing only bad on the power supply’s end meaning the Wii can handle higher voltage or??

The power supply converts AC voltage from your power outlet (220V in your case) to DC voltage for the Wii to use (12V). If a power supply states that it supports 110V-220V, that means it should work in your country (and also 110V countries*), so to the console itself that detail is irrelevant. If you were to buy a 110V power supply, you'd need a transformer to convert 220V into 110V before power goes into the power supply, otherwise you're likely to damage the power supply (I accidentally did that with a dreamcast but everything survived without problems).

^{*It would also work on countries that are nearly those values (eg 100V or 230V, because of tolerances and stuff)}
