## Description

What extension cable do you want? Resistant? We recommend HUANCHAIN extension cable. HUANCHAIN extension cable is listed by ETL. 13 Amp, 125 Volt, 1625 Watt, 16 AWG, meet safety and quality assurance. Choosing the right type of extension cable is important to ensure electrical safety. You should always have an ETL list for safety in accordance with the National Electrical Code (NEC). HIGH QUALITY CONNECTOR - Reinforced and durable connectors protect tips against bending or breakage. The long strain relief design allows the cable to bend at a larger angle without breaking (passed repeated bending test), extending the service life and making it safer to use. Sturdy but soft - The soft cord makes it easier to fix on the edges of furniture. The weather resistant jacket is more durable. It is used in an environment of -50~65°C. 3 types of length: 15 feet, 25 feet and 50 feet. Expand the reach of your home appliances and power tools with our extension cord. Perfect for small appliances or power tools. HUANCHAIN extension cable is a good choice for you.

Review: I bought this HUANCHAIN 20 ft white extension cord to use with my TV, and it’s been excellent so far. The cord feels very high quality—thick, durable, and not flimsy like cheaper options. I like that it’s flexible and doesn’t get stiff, making it easy to route behind furniture. The length is perfect for reaching the outlet without stretching or tangling. The white colour blends in nicely and doesn’t stand out. Overall, this is a well-made, reliable extension cord and definitely worth it for powering a TV setup.
Review: Works great
