What is the difference between an extension cord, a power strip, and a surge
Extension cords provide temporary reach for a single device, while power strips expand the number of available outlets without adding protection[1]. Surge protectors look like power strips but contain components that redirect excess voltage to safeguard sensitive electronics[1]. When shopping, look for UL or ETL certifications to ensure the product meets safety standards[2].
Never daisy-chain these devices or plug high-wattage appliances like space heaters and refrigerators into them[2]. Replace any unit that feels hot, shows signs of wear, or has a damaged cord immediately[2].
