In Malawi the plug type is G, which is the plug that has three rectangular pins in a triangular pattern.
The standard voltage is 220/240V and the standard frequency is 50Hz.
You can use your electric appliances in Malawi, if the standard voltage in your country is in between 220-240V (as is in the UK, Europe, Australia and the most of Asia and Africa).
If the standard voltage in your country is in the range of 100V – 127V (as is in the US, Canada and most South American countries), you need a voltage converter in Malawi.
Frequent power cuts last anything from a couple of hours to a day.
Many of the top hotels and lodges have back-up power supplies.
