Safety is our top priority. Core Plugtul products have passed relevant international safety certifications, including UL or ETL certification in the United States and cUL certification in Canada. You can find specific certification marks on the product detail pages or directly on the products themselves.
AWG stands for American Wire Gauge, which indicates the thickness of the wire. Lower numbers mean thicker wires that can handle higher electrical loads. For example, 12 AWG cords are suitable for heavy-duty use, while 16 AWG cords are best for light-duty applications.
The right extension cord depends on your usage. For light indoor devices like lamps or chargers, a 16 AWG cord is sufficient. For outdoor use or power tools, a heavier-duty 12 or 14 AWG cord is recommended for safety and performance.
Choose the shortest length that meets your needs. Longer cords can cause voltage drop, reducing performance and potentially leading to overheating. For high-power devices, shorter and thicker cords are safer.
