Can one use British appliances in Namibia?
If so what sort of adaptor plug is required?
What kind of appliances are you talking about?! If electronics then yes, today all electronics are dual voltage, 110/220. Otherwise they are on 220V/50 Hz. They do use a very specific 3-prong plug Type D. Search internet for more info.
You need the South African type three pin. Looks like UK old 'round' 3 pin but not same size.
Worry not, you can buy one in Namibia on arrival. Most garages and electric goods places stock them.
Adapters can be found in the major supermarkets as well.
The plugs in Namibia appear to be called BS 546 (round pins, 7mm leads, 9 mm earth). If I am correct, in the UK these seem to have been replaced by BS 1363 (flat pins) so you will need an adapter. Being from the Netherlands I have to use an adapter anyway, and I bought one in a local supermarket in Namibia.
Thank you to all who replied.
Every single lodge we stayed in in Namibia (10-ish) also had sockets that accepted Europlug, most in the rooms and the rest in common areas. I think I only saw the UK plug type accepted in the Hilton. Some lodges in fact didn't even have Namibian/South African sockets accessible without unplugging a light or whatever. I brought an adaptor for our Europlug devices, but we never even used it.
It's probably worth bringing an adaptor, but I wouldn't buy more than one, especially if you already have UK to Europlug adaptors.Edited: 22 May 2018, 01:18
By the way, if it is just for charging batteries, then it might come handy to have a car charger with you. The availability of a power socket on your own campsite is not guaranteed and in hotels you have to either leave your charging batteries in your room or stay with them all the time. With a car charger you won't have these problems.
