Electricity costs have increased significantly in South Africa over the past decade, which has made many households more aware of how much power their appliances consume. Everyday devices such as kettles, microwaves, air fryers, and ovens all use electricity, but the amount of power they require can vary significantly.
Understanding appliance electricity usage can help households manage energy consumption more effectively and reduce monthly electricity costs. Some appliances use high wattage but operate for short periods, while others consume smaller amounts of power but run continuously throughout the day.
In this guide we compare the electricity usage of common household appliances and explain how they contribute to overall energy consumption.
What Does Appliance Wattage Mean?
Electric appliances are usually rated in watts (W). This number shows how much electrical power the appliance uses while operating.
For example:
| Appliance | Typical Wattage |
|---|---|
| WiFi Router | 10–20W |
| Laptop | 50–100W |
| Microwave | 800–1200W |
| Air Fryer | 1500–2000W |
| Kettle | 1800–2200W |
Higher wattage appliances generally consume more electricity, but the total cost depends on how long the appliance runs.
Electricity Usage of Common Appliances
Below are typical power ranges for some common household appliances.
| Appliance | Typical Power Usage |
|---|---|
| Kettle | 1800W – 2200W |
| Microwave | 800W – 1200W |
| Air Fryer | 1500W – 2000W |
| Electric Oven | 2000W – 3000W |
| Fridge | 100W – 400W |
| WiFi Router | 10W – 20W |
Appliances such as kettles and air fryers draw high power but usually operate for short periods, while appliances like refrigerators run continuously but use less power.
Kettle Electricity Usage
Electric kettles are one of the highest-wattage appliances in most kitchens, usually ranging between 1800W and 2200W. However, they only operate for a few minutes when boiling water.
Because of this short usage time, the overall electricity cost of using a kettle is often lower than many people expect.

Microwave Electricity Usage
Microwaves generally use between 800W and 1200W, depending on the model and power settings. They are designed to heat food quickly, which means they often run for only a few minutes at a time.
This relatively short cooking time helps keep their electricity consumption fairly low compared to appliances such as ovens.

Air Fryer Electricity Usage
Air fryers have become increasingly popular in South African kitchens. Most models use between 1500W and 2000W.
Although this is similar to the wattage of a kettle, air fryers typically run longer because they cook food rather than simply boiling water.

Appliances That Use the Most Electricity
Some household appliances consume significantly more electricity than others.
Examples include:
- electric ovens
- heaters
- tumble dryers
- kettles
- air fryers
These appliances draw high wattage and can increase electricity usage if used frequently.
Tips to Reduce Appliance Electricity Usage
Households can reduce electricity consumption by:
- boiling only the amount of water needed
- avoiding unnecessary appliance use
- choosing energy-efficient appliances
- switching appliances off when not in use
Even small changes in daily habits can help reduce electricity costs over time.
Final Verdict
Household appliances vary widely in their electricity consumption. Devices such as kettles and air fryers use high wattage but usually operate for short periods, while appliances like refrigerators use lower wattage but run continuously.
Understanding how much electricity common appliances use can help households make better decisions about energy consumption and reduce monthly electricity costs.
