Power strips, an essential device in our daily lives, provide power for a wide variety of electronic devices. However, many people often confuse power strips with extension cords, or even mistakenly plug extension cords into power strips, which can pose serious safety risks. This article will delve into the differences between the two, explain why this dangerous behavior should be avoided, and share correct electrical safety practices.

Although both have outlets, extension cords and power strips differ fundamentally in their design and functionality.
Extension cords primarily extend the reach of an electrical outlet, typically with only one or two outlets. They have thinner wires and typically lack overload protection. They are primarily used for temporary, low-power devices such as lamps and chargers. They are designed for convenience rather than as permanent power solutions.
Power strips typically have multiple outlets and integrated overload or surge protection. These features detect abnormal current flow and automatically cut off power to connected devices if an overload occurs. The circuit design and components within high-quality power strips are rigorously tested to ensure safe and stable operation even when multiple devices are in use simultaneously.
Plugging extension cords into power strips, or connecting multiple power strips in series, is a dangerous practice known as "daisy-chaining." This practice carries the following risks:
To ensure electrical safety in your home and office, always follow the following guidelines:
If you have insufficient wall outlets or outlets are inconveniently located, consider the following safer alternatives:
Proper electrical habits are key to preventing fire and electric shock. For your safety and that of your family, remember: power strips and extension cords should never be used interchangeably, let alone connected in series.
