NOCO GCP1 AC Inlet 15A 125V with 16-inch Integrated Cord — Waterproof Flush-Mount

The NOCO GCP1 is a 15A, 125V flush-mount AC inlet with a 16-inch integrated outdoor extension cord and a waterproof pressure-fit cap for easy, cable-free power connections.

The NOCO GCP1 combines an inlet socket, an integrated 16-inch extension cord, and a weatherproof receptacle box into one compact, low-profile unit made for vehicles, boats, trailers, and outdoor power needs. It installs into a 2-inch mounting hole, requires no hand wiring or cable modification, and works with any Type-B extension cord for quick plug-and-play power access. Built with 14 AWG copper wiring and full-size prongs, it delivers reliable conductivity for 15-amp circuits while the rubberized cap helps keep moisture and dirt out.

How do I install the NOCO GCP1 without special tools?

Installation is designed to be straightforward—no splicing, no internal wiring, and no electrician required. The unit mounts flush with a simple flange into a 2-inch hole and secures with the provided hardware for a clean, factory-style finish.
