250V refers to the maximum voltage rating of the extension cord. This means it can safely handle currents up to 16A (amps) at 250V without overheating or causing a fire. Most household appliances in South Africa operate at 230V, so a 250V rated extension cord is perfectly suitable. Based on your question looking for a 3m extension cord, I would recommend the Noble Safy 3M Multi Plug Coupler Extension Cord, available for R45. This allows you to power up to two appliances at once from a single outlet. Its dual 3-pin sockets and 16A rating at 250V make it safe for most light household use. The short 3m length also makes it very portable and convenient to use in different spots around the home. Please let me know if you need any other information!

I would not recommend plugging a heater or stove into any of the extension cords from the previous search results. Those cords are best suited for light, low-powered devices like laptops or phone chargers. For a heater or stove, you'll want a thicker, higher rated extension cord that can safely handle the higher power load. The Ryobi Extension Cords 220V 10AMP - 15M and 20M options would be better suited as they are rated for 10 amps at 220-250V. However, for maximum safety I'd suggest using a direct wall outlet where possible for high-powered appliances like heaters and stoves. Let me know if you need any other recommendations!
