WELLUCK RV 20A 125V 5-in-1 Shore Power Inlet — Flanged 5-Tip Plug with Dual 18" 12AWG Leads, Weatherproof

The WELLUCK 5-in-1 20A/125V inlet is a weatherproof RV shore power plug with two integrated 18" 12AWG leads and five interchangeable connector tips for one-step power hookup.

Designed for RVs, trailers, boats and portable generators, this flanged inlet combines a rugged 20 amp male housing with built-in extension cords and five adapter ends so you can accept multiple plug types without carrying separate adapters. The inlet uses corrosion-resistant metal contacts and a UV-resistant nylon body, and it installs in a 2" mounting hole with four stainless steel screws. A hinged waterproof cover and sealed rear cap protect the connection from rain, snow and dust when not in use.

How does the 5-in-1 system simplify charging and shore power connections?

Instead of keeping multiple adapters in your storage bay, WELLUCK’s inlet supplies five commonly used plug terminations pre-fitted to one male housing. You choose the appropriate tip at the device end while the inlet remains fixed to your vehicle or panel. This reduces clutter and speeds setup at campgrounds, marinas or work sites.

• Includes adapters compatible with NEMA 1-15, 5-15, 5-20, 6-15 and 6-20 plug types.
• Two factory-attached 12AWG, 18" leads simplify wiring to internal circuits.
• Single inlet replaces multiple separate external adapters.

Is the inlet durable enough for outdoor and marine use?

The WELLUCK inlet uses nickel-plated copper contact pins and a nylon housing that resists UV, chemicals and physical wear. The contact plating helps prevent oxidation and ensures consistent conductivity over time. A weatherproof front cover plus a sealed rear cap keep moisture and debris out of the connection area.

• Nickel-coated copper poles for improved corrosion resistance.
• UV-stable nylon body resists brittleness and cracking outdoors.
• Hinged waterproof cover and back cap seal against storm conditions.

How simple is installation and what wiring do I need?

Install the flanged inlet using a 2" hole cutout and fasten it with the included four stainless-steel screws for a snug, gap-free mount. The inlet arrives with two 18" 12AWG leads already attached, so you only need to connect those conductors to your internal power distribution or charger input. Follow local electrical codes and, if unsure, have a licensed electrician complete the final connections.

• Requires a 2" mounting hole and four screw points for secure installation.
• Pre-attached 12AWG wires reduce preparation time during fitting.
• ETL-approved components support recognized safety standards.

What devices and situations is this inlet compatible with?

The inlet supports common small-vehicle and light-duty power requirements, acting as a shore power inlet, generator input, or charger connector for many recreational and work applications. When using 6-15 or 6-20 adapters, confirm your equipment supports the broader voltage range noted by the manufacturer. It’s suitable for campers, trailers, boats, portable generators and block heaters among other uses.

• Works with trailers, RVs, campers, boats, and marine systems.
• Can serve as a generator input or battery charger inlet.
• Accepts multiple NEMA plug standards for flexible hookups.

Who is this for: The WELLUCK 20A 5-in-1 inlet is aimed at RV owners, boaters and tradespeople who want a compact, weatherproof shore power solution that accepts multiple plug styles without swapping external adapters. It’s also a practical retrofit for fleet vehicles and trailers that need a reliable outdoor inlet with built-in wiring and corrosion-resistant components.
