UBOORY Outdoor Extension Cord Waterproof 100 ft – 16/3 SJTW Heavy Duty, 3-Prong

Extended outdoor power when and where you need it

The UBOORY Outdoor Extension Cord delivers dependable reach for yards, garages, tents, and work sites. With a 100 ft length and a 16 AWG SJTW construction, this heavy-duty cord supports up to 10A at 125V, equating to about 1250W of practical load. The dual NEMA 5-15P to 5-15R configuration makes it compatible with common home outlets, enabling you to power lights, tools, or appliances without frequent re-plugging.

Durability is built into its design. The cord uses 100% copper conductors for efficient power transfer and lower heat buildup over longer runs. The insulation is flame resistant and weatherproof, ready to handle rain, dew, and outdoor exposure. It remains flexible even in cold weather down to -50°C, and its corrosion-resistant jacket helps it tolerate humid environments.

In everyday use, you’ll notice a longer life thanks to a robust strain relief that endures thousands of bends. The cord ships with Velcro storage strips for neat coiling and simple storage when not in use.
