Running power 100 feet is where cheap cords fail — voltage drops, tools bog down, plugs run hot. This Conntek advanced-duty cord pairs true 20 Amp NEMA 5-20 ends with heavy 10-gauge/3-conductor wire, so high-draw equipment still gets solid power at the far end of the run. The SJTW jacket is a weather-resistant outdoor grade that handles jobsites, events, holiday lighting, and backyard projects. If you need serious reach without giving up amperage, this is the cord to keep on the truck. New surplus stock — factory direct.
