Do I need to bring a travel adapter?

South Africa and its neighbouring countries have 220V power. It is always best to bring your own travel adapter, in case. Have a look at Amazon's universal travel plug for South Africa and International Electrical Supplies' travel adapters for details of various adapters.

You will need WA7 for northern Botswana, Zambia and Zimbabwe, and WA10L for South Africa. In Kenya, plugs are 240V with a type G power socket, with square prongs like those in the UK.
