NOCO GPC1 AC Port Plug Power Inlet

#van#vanbuild#camper
Watch original on Youtube

This bundle focuses on installing the NOCO GPC1 AC Port Plug in a van. It provides the core components and tools needed to add external AC power input to a camper van. This setup allows for easy shore power connection for battery charging and appliance use.

Curated by Workshop Notes · Updated June 2026

Built for DIY van builders and trailer owners who need a clean, weatherproof connection for shore power without hacking a giant hole in their chassis. Not for heavy-duty 30-amp or 50-amp RV service—this shop focuses strictly on 15-amp residential-style pass-throughs.

Curator's pick: GPC1 15-Amp AC Port Plug

This is the only flush-mount plug I trust because the rubber gasket actually seats properly against curved body panels. Skip the knock-offs; the plastic on this unit doesn't get brittle after a season of UV exposure, which prevents the mounting ears from snapping off during cord insertion.

⚠ Worth knowing: The internal cord is only about 16 inches long, so you cannot reach your battery charger directly with it. You must secure the 12AWG extension cord to your internal frame with P-clamps to prevent the plug's internal wiring from vibrating loose under heavy road shake.

What works

  • Provides a clean and secure external AC power connection, eliminating loose cords and reducing safety hazards.
  • Enables efficient charging of your camper's battery bank and powering of onboard appliances when connected to shore power.
  • Significantly enhances the functionality and convenience of your van, making it ready for extended stays at campsites or powered locations.

What to know

  • Installation requires cutting a hole into the van's exterior, which needs careful planning and execution to avoid leaks and structural issues.
  • The setup provides the inlet to your van but does not include internal wiring beyond the extension cord, requiring additional components for a complete electrical system.

How to use this together

  1. 1

    Drill the Opening

    First, select the exact mounting location for your NOCO GPC1 AC Port Plug on the exterior of your van, ensuring there's clearance on the interior side. Use the M12 Fuel 1/2 Inch Drill Driver with the 2-inch Bi-Metal Hole Saw to carefully cut a precise circular opening. This initial step is critical for a flush and secure mount.

  2. 2

    Seal and Secure the Port

    After cutting the hole and before mounting the GPC1 15-Amp AC Port Plug, apply the Professional Zinc Galvanizing Spray to any newly exposed metal edges to prevent rust and corrosion. Then, apply a generous bead of 202 Clear Silicone Sealant around the perimeter of the opening and the flange of the port plug. Mount the GPC1 AC Port Plug firmly, ensuring a watertight seal to prevent moisture intrusion into your van.

  3. 3

    Connect Internal Power

    From the inside of your van, connect the 12AWG Heavy Duty Extension Cord 10 Feet directly to the contacts of the NOCO GPC1 AC Port Plug. This cord will extend power safely into your van to connect to an internal power strip, battery charger, or other electrical systems. Ensure all connections are secure and properly insulated.
