USA to South Africa Device Power Problem

I was bought a gift from Amazon USA and the specs are AC 110-120V/60hz power consumption 300w. I am based in South Africa and my device is not powering up with a normal plug converter. Do I need to convert my USA device from 120V to South Africa’s 220V? Can you have a look at the pics and tell me what I need or recommend for it to work in SA?

Yes, you need a transformer from 220v to 110v, see this page:
