Extension cords, power strips, and cord reels are products that supply power to devices that don't have convenient access to a power source. Extension cords are a length of flexible electrical cable used to power devices located at a distance. They are commonly used when a device's cord is too short to reach an electrical outlet or where outlets may be scarce. Power strips are a flexible cable with a block of electrical sockets that supply power to multiple devices at the same time from one power outlet. Also known as outlet strips, they are typically used to provide additional outlets in areas that don't have enough wall receptacles for the number of devices. Extension cord reels hold extension cords for convenient access and storage, protecting cords from wear and damage, minimizing tripping hazards, and helping prevent tangling and kinking.
