Paul the main concern here is voltage here we have 220-240 AC.

I do not know the type of plug you use in SA but as soon as you arrive you can go to stores like Carrefour, Lulu Hypermarket, Giant Stores end there you can find plug converters to fit the ac plug available here.

If you make it to a Hotel you can ask the concierge service to provide you with one of these converters.

But if your devices or appliances do not use 220-240 or are not capable of using this AC voltage then yopu will have to buy an AC converter to make 220-240 into 110. These also available in big stores.

Best of luck...and welcome
