SunnyLith 20A RV Shore Power Inlet Plug — Dual AC Ports, 12AWG Waterproof with 20-inch Integrated Cord & 5-in-1 Adapter

SunnyLith's 20A RV shore power inlet plug is a waterproof, dual-AC port receptacle with a 20-inch integrated extension and a 5-in-1 NEMA adapter for powering two devices at once.

This compact inlet combines a rugged 12 AWG copper-wired socket, a weather-sealed enclosure, and a multi-plug adapter so you can connect a variety of household and RV cords without rewiring. Designed for exterior mounting, it’s built to resist rain, snow, and dust while delivering 20 amps at 125 volts through two separate outputs—making it a practical shore power solution for trailers, campers, boats, and outdoor equipment.

How does this inlet allow two devices to run from one shore power connection?

The SunnyLith unit features a dual AC port design that splits a single 20A feed into two accessible outlets, so you can plug in two appliances or shore cords simultaneously. The integrated 5-in-1 adapter accepts several common NEMA plug types for broad compatibility.

• Dual 16-inch outlet cords provide two independent connection points.
• Built-in 5-in-1 adapter supports NEMA 1-15P, 5-15P, 5-20P, 6-15P, and 6-20P.
• Rated for 20A/125V output with 12 AWG copper wiring for efficient current flow.

Is the inlet safe for outdoor and marine conditions?

Yes — the inlet housing is designed for outdoor use with a rubberized, watertight cap and a protective cover that keep moisture and debris out of the receptacles. The enclosure and materials resist corrosion and wear from sun, salt air, and winter weather when mounted correctly.

• Sealed rubber cap and hinged cover prevent water intrusion.
• Durable nylon housing resists UV exposure and impact.
• Flush-mount design keeps the unit secure and reduces snag points.

How difficult is installation and what tools are needed?

Installation is intended to be simple and mostly tool-free: the inlet fits a common 2-inch cutout and mounts flush to the surface. No internal rewiring or complex electrical work is required for typical shore power use—making it a quick plug-and-play upgrade for most RVs and trailers.

• Fits 2-inch mounting hole for quick flush installation.
• Integrated 20-inch cord connects directly to shore power—no extra adapters needed for many setups.
• Basic hand tools recommended for secure mounting; no advanced electrical modifications expected.

What cords and devices are compatible with this 20A plug?

The adapter accepts common household and RV plug styles, enabling connection of standard 110–125V devices and some 6-series plugs when the equipment supports the required voltage. Check your device ratings—6-15/6-20 use typically requires equipment able to accept 110–250V to function safely.

• Compatible with NEMA 1-15P, 5-15P, 5-20P, 6-15P, and 6-20P plugs.
• Best suited for 125V devices; verify voltage compatibility for 6-series plugs.
• Useful for RVs, boats, enclosed trailers, golf carts, and outdoor power needs.

Who is this for? Owners of RVs, trailers, small boats, and outdoor equipment who want a robust, weatherproof inlet that supports dual connections and multiple plug standards will find this SunnyLith unit useful. It’s aimed at DIYers and fleet operators who need a compact, reliable shore power solution that installs quickly and broadens compatibility without complex wiring changes.
