Curated by The Shelf Curator · Updated June 2026
Built for boat owners and RVers who need to route power through a hull or exterior wall without leaving a mess of loose wires. Not for permanent residential wall wiring—this shop focuses on surface-mount port plugs and the tools required to install them properly.
Curator's pick: GCP1 15A AC Port Plug with 16-Inch Integrated Extension Cord
It replaces the need for a standard inlet box because the integrated cord lets you plug directly into a charger or power strip without stripping wires. The rubber cap actually stays seated in vibration-heavy environments, which is usually the failure point on cheaper generic ports.
⚠ Worth knowing: These plugs require a 2-inch hole saw for installation, which is a massive hole if you miscalculate your clearance behind the panel. Also, while waterproof when capped, the pins are susceptible to salt corrosion if left open and exposed to spray for extended periods.

How to use this together
1
Prepare the Mounting Surface
Begin by selecting a flat surface on your boat, RV, or equipment that is clear for both interior and exterior access. Use the 2-Inch Bi-Metal Hole Saw to drill a clean, precise hole through the chosen material. This tool is specifically designed for this purpose, ensuring a perfect fit for your NOCO port plug.
2
Install the AC Port Plug
Once the hole is drilled, apply a generous bead of 100% Silicone Marine Grade Sealant around the edge of the hole, both inside and outside. Carefully insert either the GCP1 or GCP2 (depending on your power needs) into the prepared opening, ensuring a snug fit. The sealant is crucial here to create a watertight barrier, preventing moisture intrusion into your vehicle's interior.
3
Connect and Seal Wiring
On the interior side, connect the integrated extension cord of the NOCO port plug to your internal electrical system, ensuring all connections are secure and properly insulated. After confirming connections, apply additional sealant around the backside of the port plug and any exposed wiring entries to further reinforce the waterproof integrity, making sure to work it into any gaps.
4
Power and Maintenance
If you are utilizing the GENIUS10 Smart Battery Charger, plug it into the NOCO AC Port Plug. Connect the charger to your vehicle's battery. The charger will automatically diagnose and maintain your battery, ensuring optimal performance and extending its lifespan. When needing to power external devices, simply plug the 12 Gauge 15 Amp Heavy Duty Indoor/Outdoor Extension Cord into the NOCO port plug.
