Can a 120 volt item be used in SA?

Yeah, appologies if it got a bit too technical but hopefully you got the gist of it which is that overload is fairly likely even though just a cursory look at the ratings of each item might appear to suggest otherwise. I don't know how much your power supply cost but it might be a better solution to purchase a second one and configure it so each wave maker has it's own power supply/converter.

It certainly would have been cheaper if I had bought the wave makers in SA instead of from Amazon. They would be rated at 220v.
The transformer cost R160.
