NOCO GCP2 15A AC Power Inlet — Waterproof Flush-Mount with Dual 18-inch Integrated Extension Cords

The NOCO GCP2 is a flush-mount, 15A 125V waterproof AC power inlet with dual 18-inch integrated outdoor extension cords for simple, no-wiring installation.

Designed to add a convenient, weather-resistant power inlet to vehicles, boats, trailers, RVs and outdoor equipment, the NOCO GCP2 combines an ultra-low-profile inlet socket with two short integrated cords so you can plug in standard Type-B extension cords without cutting or splicing wires. The unit mounts into a 2" hole and includes a pressure-fit rubber cover to keep moisture and debris out when not in use. Built with 14 AWG copper wiring and full-sized prongs, it supports common 15-amp, 125-volt applications and is UL approved for safety compliance.

How does the GCP2 make installing an outdoor power inlet easier?

Installation is designed to be straightforward: the GCP2 is a plug-and-play inlet that requires no hand wiring or cable modification. It mounts into a standard 2" hole and secures with a flanged faceplate, so most users can complete installation with basic tools in minutes.

• Flush-mount flange fits a 2" cutout for neat installation
• Dual 18" integrated cords eliminate splicing or hardwiring
• Pressure-fit rubber cover secures to keep out water and dirt
• Compatible with any Type-B extension cord for fast setup

What protection does it offer for outdoor and marine use?

The GCP2 is built with a rugged housing and a rubberized cap to resist exposure to rain, splashes and road spray. While not a permanently submersible device, its pressure-fit cover and sealed design give effective weather resistance for exterior-mounted power inlets when used as intended.

• Waterproof cap provides a tight seal when closed
• Durable housing resists corrosion and impact in outdoor conditions
• Integrated cords routed through a protected body reduce entry points for moisture
• UL approval indicates compliance with recognized safety standards

Which applications and devices work best with the NOCO GCP2?

The inlet is rated for 15 amps at 125 volts and uses heavy-duty 14 AWG copper wiring, making it suitable for many accessory power needs without overspecifying. It is commonly installed for onboard battery chargers, engine block heaters, shore power connections on trailers and RVs, and as a weather-protected exterior outlet on vehicles and equipment.

• Onboard battery chargers for cars, trucks and boats
• Engine block heaters and seasonal heating accessories
• Shore power inlet for trailers, campers and RVs
• Outdoor receptacle for pumps, lights or portable tools

How does the dual integrated cord design benefit everyday use?

Having two short integrated cords gives flexibility in where and how you connect a standard extension cord without having to open the unit or perform wiring. The cords provide immediate, safe connection points and reduce the need for extra adapters or specialized cables.

• Two 18" leads allow routing to either side or different compartments
• Works with off-the-shelf Type-B extension cords for convenience
• Reduces installation time and potential wiring errors
• Maintains a clean exterior appearance with a low-profile faceplate

Who is this for: The NOCO GCP2 is ideal for vehicle owners, boaters, RV and trailer users, fleet operators and technicians who need a compact, durable and code-friendly exterior power inlet without the complexity of hardwiring. If you want a neat, weather-resistant inlet that accepts standard extension cords and supports common 15A accessories, the GCP2 offers a practical, quick-to-install solution.
