240-to-120 transformer for 1500w (Berkeley)

If anyone has a step-down transformer that can handle 1500w or higher, I'd apperciate it. E.g.: https://www.amazon.com/s?k=1500w+step-down+transformer
(I have standard US-based 120 outlets and a 1500w device created for European 240 outlets. I was told a 240-to-120 step-down transformer is what I need.)
