stio 20A 125V RV Shore Power Inlet Plug with 6ft 12AWG Cord — 5-in-1 Adapter, Weatherproof Flush-Mount

The stio 20A 125V AC inlet plug is a heavy-duty, weather-resistant shore power inlet with a 6ft 12AWG cord and a removable 5-in-1 T-blade adapter for broad NEMA compatibility.

This inlet plug combines a durable 20-amp rated housing, thick copper conductors, and a watertight rubber cover to deliver a dependable outdoor power connection for RVs, boats, trailers, and other mobile or exterior installations. It’s designed for straightforward flush-mount installation into a 2-inch hole and ships with a flexible 6-foot extension cable so you can connect to shore power without cutting or rewiring. The included 5-in-1 adapter accepts common plug types so one unit fits multiple power sources while preserving safe current capacity.

How does the 5-in-1 adapter simplify connecting to shore power?

The integrated female adapter accepts five common NEMA plug styles (1-15P, 5-15P, 5-20P, 6-15P, 6-20P), letting you use a single inlet for several plug types. It reduces the need to carry separate adapters and lets different vehicles or cords share one power inlet while the inlet maintains its 20A rating.

• Accepts NEMA 1-15P, 5-15P, 5-20P, 6-15P, 6-20P plugs
• One-plug solution reduces adapter clutter
• Adapter designed to fit securely without extra tools

What makes this inlet reliable for outdoor and winter use?

The housing uses black nylon plastic and heavy copper wiring for durable electrical performance, and a pressure-fit rubberized cover creates a watertight seal. The snap-fit cap shields the connection from snow, rain, and freezing conditions so the inlet stays protected in harsh weather.

• Pressure-fit rubber cover for watertight protection
• Snap-fit cap prevents ice and debris buildup
• Weather-resistant materials rated for exterior exposure

How easy is installation and what are the electrical specs?

Installation is plug-and-play: the inlet is a flush-mount flange that fits a 2-inch hole and requires no cable modification or hardwiring. It comes pre-wired with 12 AWG copper conductors and a 6-foot cord, rated at 20 amps and 125 VAC for consistent power delivery.

• Fits standard 2-inch mount opening for quick installation
• Pre-wired 6ft 12 AWG cord for immediate connection
• Rated 20A, 125VAC for common RV and marine applications

Where can this inlet be used and what devices is it compatible with?

This inlet is built for multi-scene use: RVs, boats, trailers, carts, cabins, sheds, and light industrial setups. While the adapter accepts 6-15/6-20 plugs, connected equipment must support the appliance’s voltage range and current rating before using those plug types.

• Ideal for RVs, boats, trailers, golf carts, and utility vehicles
• Suitable for outdoor sheds, cabins, and light industrial power needs
• Check device voltage range before using 6-15/6-20 adapters
