20A 125V RV Shore Power Inlet Plug

PAULINN’s 20A 125V RV shore power inlet is a ready-to-install, waterproof AC receptacle with a built-in 5-in-1 T-blade adapter and 18" dual 12AWG extension cords for flexible, heavy-duty shore or generator connections.

This compact inlet combines a universal multi-plug adapter, integrated weather cover, and two pre-wired 18-inch 12AWG leads so you can add shore power or generator input quickly without rewiring. ETL-listed and rated 20A/125V, it fits standard 2" mounting cutouts and aims to simplify power hookup for RVs, trailers, boats, trucks, and backup generator setups.

How does the 5-in-1 adapter make hookups easier?

The included 5-in-1 T-blade adapter accepts common plug types so you can connect a wider range of shore and generator cords without extra converters. It covers everyday 1- and 2-prong household plugs and common 3-prong 20A and 15A configurations for RV and generator use.

• Works with NEMA 1-15P, 5-15P, 5-20P, 6-15P and 6-20P plugs
• Single plug provides five adapter options—no separate adapter pieces to lose
• Allows 110–250V connection for devices when using 6-15/6-20 plug types (device-dependent)
• Saves space and reduces clutter compared with separate adapters

What makes installation so fast and tool-friendly?

No internal rewiring or cable modification is required: the inlet arrives pre-wired with two 18-inch 12AWG leads and mounts into a 2" hole using four screws. The straightforward fit-and-secure design gets you from bench to powered in minutes.

• Pre-installed dual 12AWG extension cords—no splicing or crimping
• Requires a simple 2" surface cutout and four mounting screws
• Flush edge design reduces trimming and finishing work
• Installation can be completed in under five minutes with common tools

How does this inlet perform outdoors and in harsh conditions?

The inlet includes an integrated protective cover and rugged housing to shield contacts from rain, snow, and dust when not in use. ETL listing and heavy-gauge copper wiring help maintain reliable conduction and safety in demanding environments.

• Integrated weather cover keeps moisture and debris away from contacts
• Heavy-duty 12AWG copper wires for stable current delivery
• ETL-listed for added verification of safety standards
• Built to withstand cold, wet conditions typical of outdoor marine or mountain use

What devices and situations is this inlet suitable for?

This inlet is designed as a general-purpose shore power or generator input for mobile and stationary applications. It’s appropriate for powering RV systems, battery chargers, block heaters, and portable equipment where a 20A/125V feed or compatible adapter is required.

• Works for trailers, campers, RVs, trucks, and boats
• Useful as a generator input or dedicated charger inlet
• Can serve home backup, block heaters, and recessed outlet boxes
• Not intended to change appliance voltage—match plug and device ratings

It suits anyone seeking a compact, weather-resistant inlet with multi-plug convenience—especially users who prefer to avoid on-site wiring or custom adapters while maintaining a heavy-duty, code-conscious connection.
