lithbase 20A 125V Shore Power Inlet Plug with 16" 12AWG Cord — Weatherproof RV/Boat Flush-Mount Receptacle

lithbase 20A 125V shore power inlet plug with a 16-inch integrated 12AWG extension cord provides a ready-to-install, weatherproof AC inlet for RVs, trailers, boats and outdoor equipment.

This heavy-duty inlet pairs a full-size 125V AC port with thick 12AWG copper conductors and a molded 16-inch cord, creating a compact shore-power solution that mounts flush into a 2-inch hole. Built for outdoor service, the unit includes a pressure-fit rubber cover to keep moisture and debris out of the receptacle while still offering easy plug access. The plug is designed for quick installation—no cable splicing or complex wiring changes—so you can add or replace a shore power inlet in minutes.

How does this inlet handle outdoor exposure?

The housing and pressure-fit rubberized cover protect the electrical contacts from rain, dust and splashes, reducing corrosion and improving longevity. The weather-resistant design means fewer service interruptions when you use shore power in marinas, campgrounds or work sites.

• Sealed rubber cover resists water and dirt ingress
• Rugged outer shell built for outdoor environments
• Durable contacts resist corrosion for reliable connection

Will this provide enough power for common RV and boat needs?

Yes — the inlet supports up to 15–20 amps at 125 volts using heavy 12AWG copper wiring, allowing it to supply typical shore-power loads like lighting, small appliances and HVAC on lighter setups. The full-size prongs maximize conductivity for stable power transfer.

• 12AWG heavy-duty wiring for reduced voltage drop
• 15A/20A rating suitable for many recreational and marine loads
• Full-size prongs for dependable electrical contact

How simple is installation and setup?

Installation is designed to be plug-and-play: the flanged, flush-mount inlet fits into a standard 2-inch hole, and the integrated 16-inch cord eliminates on-site splicing. No special tools or rewiring are required for most installations, so you can mount it quickly and restore shore power fast.

• Flush-mount flange fits 2-inch installation openings
• Pre-attached 16-inch extension cord means no cable modification
• Minimal tools and time required for typical mounting jobs

What maintenance or service should I expect?

Routine maintenance is minimal: keep the cover closed when not in use, inspect the cord and contacts periodically for wear, and clear debris from the housing. lithbase also provides customer support to assist with product questions or installation guidance around the clock.

• Close cover after each use to protect contacts
• Check cord and screws regularly for snug fit and wear
• Access lithbase 24/7 customer support for help
