stio 20A 125V Shore Power Inlet Plug with 5-in-1 T-Blade Adapter, 6ft 12AWG Cord, Weather-Resistant

The stio 20A 125V AC inlet plug is a ready-to-install, weather-resistant shore power inlet with a 5-in-1 T-blade adapter and 6-foot 12AWG cord for versatile outdoor and vehicle power connections.

This inlet plug combines a heavy-duty 20-amp, 125-volt wiring assembly with five common adapter configurations so you can plug into multiple receptacle types without rewiring. Built with durable copper conductors, a molded nylon housing and a rubberized weather cap, it aims to simplify shore power hookup for RVs, trailers, boats, and outdoor electrical projects while resisting moisture, salt and cold.

How does the 5-in-1 adapter expand compatibility?

The integrated female adapter accepts five common plug standards so one inlet works with many shore power sources. You don’t need separate adapters or replacement inlets when traveling between campgrounds, marinas or work sites.

• Accepts NEMA 1-15P, 5-15P, 5-20P, 6-15P and 6-20P plugs.
• One purchase replaces multiple single-adapter setups.
• Supports wide-voltage devices when using 6-15/6-20 (confirm device voltage compatibility).

Is the inlet durable enough for outdoor and marine use?

Yes — the housing uses heavy-duty nylon and copper conductors with a sealed rubber cap to resist water and freeze damage. The design helps keep electrical contacts dry and reliable in rain, snow or salty conditions commonly found on boats and outdoor equipment.

• Weather-resistant rubberized cover with pressure-fit seal.
• Snap-fit watertight cap protects against snow, ice and freezing rain.
• Molded nylon body resists impact and UV exposure.

How easy is installation and what wiring does it use?

This inlet is designed for a flush-mount, plug-and-play installation into a 2-inch hole, requiring no field splicing or complex wiring. The unit ships pre-wired with heavy 12 AWG copper conductors and a 6-foot cord for direct connection to shore power or an extension source.

• Pre-wired 6 ft 12 AWG cord for high current capacity and conductivity.
• Flush-mount flange fits a standard 2-inch cutout; screws included for mounting.
• No hand-wiring needed — saves installation time and reduces wiring errors.

What vehicles and applications is this inlet best suited for?

The inlet is broadly compatible with RVs, trailers, boats and outdoor structures where a robust, weatherproof shore power connection is required. It’s intended for standard 20A, 125VAC applications — confirm device voltage ratings before connecting devices using 6-15/6-20 adapters.

• Commonly used on RVs, campers, trailers, boats and golf carts.
• Also useful for sheds, workshops, cabins and light industrial setups.
• Works well for seasonal or mobile power needs where weather protection matters.

Who is this for: The stio 20A inlet plug is aimed at RV owners, marine users, trailer and off-grid vehicle owners, and DIYers who want a single, weatherproof inlet that covers multiple plug standards without rewiring. Choose this unit if you need a sturdy, quick-to-install shore power inlet with a versatile adapter set and a heavy-duty 6 ft cord for reliable outdoor power connections.
