This bundle focuses on reliable AC power access and charging solutions, centered around the NOCO GCP2 15 Amp 125V AC Port Plug. It's designed for vehicle and marine owners who need convenient external power connections and robust battery maintenance. The included products provide options for AC input, USB device charging, and multi-bank battery charging.

Curated by The Shelf Curator · Updated June 2026

Built for boat owners and RV operators who need a clean, weatherproof power inlet to charge batteries without draping loose cords through windows or hatches. Not for high-draw industrial machinery—this shop focuses on 15-amp shore power and trickle-charging setups.

Curator's pick: GCP2 15 Amp AC Port Plug with Dual Extension Cords

The dual-cord design is the most practical choice because it allows you to power a dedicated charger and a heater or dehumidifier through a single exterior port. The build quality on the gasket is superior to generic knockoffs, which usually dry rot after one season in salt air.

⚠ Worth knowing: These port plugs require a 2-inch hole saw for installation, so ensure you have clear depth behind your mounting surface before drilling. They are rated for 15 amps maximum; attempting to run a heavy-duty AC unit alongside other appliances will likely trip your internal breaker or overheat the plug.

What works

  • Provides seamless and safe external AC power connectivity for multiple on-board devices or systems, eliminating the need to have cords hanging out of closed compartments.
  • Ensures optimal battery health and readiness for multi-battery setups in harsh environments, extending battery life and preventing unexpected power loss.
  • Offers convenient and high-speed charging for personal electronic devices directly from your vehicle or boat, keeping essential gadgets powered on the go.

What to know

  • Initial installation of the port plugs requires drilling and wiring, which might be a barrier for those uncomfortable with vehicle modifications.
  • While versatile, the bundle's components are largely specific to 125V AC input and battery charging, potentially limiting utility for other power needs.

How to use this together

  1. 1

    Install the AC Port Plug

    Begin by selecting either the GCP2 (dual cords) or GCP1 (single cord) AC Port Plug based on your needs. Choose a suitable, accessible location on your vehicle or boat for installation, ensuring it's protected from excessive exposure. Drill the necessary holes and secure the plug, routing the internal extension cord(s) to where your devices or charger will be located. This establishes the primary external power input point.

  2. 2

    Connect the Extension Cord

    Once the AC Port Plug is installed, use the Protective Heavy Duty Extension Cord 10 Feet to connect the port plug's external face to a reliable shore power or external AC outlet. This provides the necessary power flow into your vehicle or marine vessel. Ensure all connections are secure to prevent power loss or safety hazards.

  3. 3

    Integrate Charging Solutions

    Internally, connect the Genius GEN5X2 2-Bank 10-Amp Waterproof On-Board Marine Charger to one of the AC Port Plug's internal cords. Wire the charger to your marine or RV batteries as per its instructions. For personal devices, plug the GBC011 65W USB-C Charger into the remaining internal AC cord (if using the GCP2) or directly into an onboard AC outlet. This setup allows for simultaneous battery maintenance and device charging.
