They are powering two chicken water heaters and a string of LED lights. I would recommend this product for outdoor use. ### ⭐⭐⭐⭐⭐ Review *by A***R on 28 December 2025* Perfect for my Christmas lights… better than bright orange cords ### ⭐⭐⭐⭐⭐ Review *by S***L on 12 January 2026* 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. ## Frequently Bought Together - HUANCHAIN Indoor Outdoor Black Extension Cord 25 ft Waterproof, 16/3 Gauge Flexible Cold-Resistant Appliance Cord Outside, 13A 1625W 16AWG SJTW, 3 Prong Heavy Duty Electric Cord, ETL - HUANCHAIN Indoor Outdoor Black Extension Cord 50 ft Waterproof, 16/3 Gauge Flexible Cold-Resistant Appliance Extension Cord Outside, 13A 1625W 16AWG SJTW, 3 Prong Heavy Duty Electric Cord, ETL - Cablelera Power Cord Extension and Splitter, NEMA 5-15P to NEMA 5-15R x 2, 16 AWG, 13A, 125V (ZWACPQAG-14) Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/554446551-huanchain-black-indoor-outdoor-extension-cord-25ft-waterproof-16-3](https://www.desertcart.vn/products/554446551-huanchain-black-indoor-outdoor-extension-cord-25ft-waterproof-16-3) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-15*
