“100 Rand per Fan per Month”: Johannesburg Man Breaks Down Electricity Costs of a Fan

• A Johannesburg electricity expert explained that fans use between 50 and 150 watts per hour, with an average of 100 watts per hour to run
• His calculations show that using a fan for one hour daily costs about 12 rand per month
• The TikTok video gained over 59,000 views as South Africans asked questions about other appliances and compared fan costs to air conditioners

A Johannesburg electricity expert has helped South Africans understand exactly how much it costs to run a fan, breaking down the numbers in a way that's easy to understand.

Content creator @djwesreddy, who specialises in sharing information about power usage and electricity costs, posted a video on 1 September 2025 explaining the monthly expenses of keeping cool with a fan.

In his video, @djwesreddy explained that different types of fans use between 50 and 150 watts every hour. Using 100 watts as a good average, he calculated that this equals 0.1 kilowatt hour per hour, which at four rand per unit costs 40 cents per hour.

The electricity expert broke down the monthly costs in simple terms that anyone can follow. If you use a fan for just one hour every day, it will cost you around 12 rand per month. However, if you're running it for eight hours per day for 30 days, the cost jumps to 96 rand per month.

"So 100 rand per fan per month is a good average cost number to work on," @djwesreddy explained.

He also provided a helpful comparison, noting that fans use between 50 and 150 watts, while air conditioners use between 1,000 and 3,000 watts, showing the huge difference in electricity consumption.

Why knowing appliance costs matters now

According to the information on Eskom's website, in 2025, electricity prices went up again. Direct Eskom customers started paying about 12.7% more from April, while people who get power through municipalities saw an 11.3% increase from July. With these hikes, South Africans need to pay closer attention to how much their appliances use, because electricity is getting more expensive every year.
