WELLUCK RV Shore Power Inlet Plug 20A 125V 5-in-1 — Weatherproof Flanged Housing & 12AWG Leads

This compact inlet plug converts a single hardwired male shore power inlet into five commonly used female connectors, giving RV, trailer, marine and outdoor power users a fast way to accept NEMA 1-15, 5-15, 5-20, 6-15 and 6-20 plugs. Built from nickel‑coated copper contacts and UV-resistant nylon, the unit ships with two 18" 12AWG leads for robust current delivery and a gasketed cover to keep moisture and dust out.

How does this inlet plug manage multiple plug types?

The WELLUCK 5-in-1 inlet provides a single male shore inlet wired to two 12AWG extension leads that accept five standard NEMA female connectors. You simply plug the device into shore power and then connect your appliance cord to the matching NEMA adapter. Using the 6-15 or 6-20 adapters requires equipment rated for broader voltages (110–250V).

• Includes adapters for NEMA 1-15, 5-15, 5-20, 6-15 and 6-20 plugs.
• Two pre-installed 12AWG 18" leads provide solid current capacity and flexibility for wiring.
• Single male inlet offers one convenient shore connection accepting multiple cord types.

Will this hold up outdoors and in harsh climates?

The inlet is built with nickel‑plated copper poles and UV-resistant nylon to resist oxidation, sunlight degradation and common chemicals. It includes an ETL-approved, gasketed weatherproof cover that helps protect contacts from rain, snow and dust, making it suitable for RV exteriors, marine applications and cold‑weather use.

• Nickel-coated copper contact pins resist corrosion for longer electrical life.
• UV-resistant nylon housing withstands sun exposure without cracking.
• Gasketed, spring‑hinged cover keeps moisture and debris away from the inlet.

How simple is installation and mounting?

Installation is straightforward: cut a 2" panel hole, feed the pre-wired leads through, and secure the flanged inlet with the supplied four stainless steel screws for a tight, flush fit. The mounting flange eliminates edge gaps and creates a neat, weatherproof barrier between the inlet and the mounting surface.

• Requires a 2" diameter hole for remote or wall mounting.
• Four long stainless steel screws included for secure fastening.
• Flanged design minimizes edge gaps and seals against the surface.

What devices and environments is this compatible with?

The WELLUCK inlet is intended for general shore power and generator use — ideal for RVs, campers, trailers, boats, block heaters and portable generators. It accepts a broad range of common cord types so you can power onboard systems, battery chargers and small appliances as long as the connected equipment matches the adapter’s voltage and amp ratings.

• Works with trailers, RVs, boats, motorhomes and recessed outlet boxes.
• Good for generators, battery chargers and portable power devices.
• Designed for 20A service at typical 125V shore power configurations.

Who is this for: The WELLUCK 20A 125V RV Shore Power Inlet Plug is designed for DIY RV owners, marine enthusiasts, fleet maintainers and installers who want a compact, durable inlet that accepts multiple household and equipment plug types.
