How Long is the Lifespan of a Power Cord?

The lifespan of a power cord mainly depends on the usage environment, usage habits, and the quality of the materials. It is generally difficult to give a specific time frame, but under normal usage, the lifespan of a power cord can last 3 to 5 years or even longer. Proper usage and maintenance can extend its lifespan, but if the power cord frequently carries a current load exceeding its specifications, it may lead to overheating or insulation damage, shortening its lifespan. If signs of aging, cracking, or exposed wires are found, the power cord should be replaced promptly to ensure safety.
