stio 20A 125V Outdoor Power Inlet with 5-in-1 T-Blade Adapter, 20" 12AWG Cord — Weatherproof RV Shore Power

The stio 20A 125V outdoor power inlet is a weatherproof, plug-and-play shore power receptacle with a 5-in-1 T-blade adapter and 20-inch 12AWG cord for versatile RV, marine, and outdoor electrical connections.

This integrated inlet combines a heavy-duty female power receptacle, a built-in 5-in-1 adapter set, and a short extension lead to give you a single, easy-to-mount solution for connecting shore power, generators, or extension cords. Designed for exterior use, the unit uses durable materials and a pressure-fit, rubberized cover to resist rain, snow, and incidental spray so you can rely on it in seasonal and mobile setups.

How does this inlet handle different plug types?

The unit includes a female side that accepts five common T-blade plug formats, allowing a single inlet to serve multiple plug standards without swapping hardware. It’s a practical way to accommodate visitors, rental gear, or hybrid setups while keeping wiring tidy and safe.

• Includes adapters compatible with 1-15P, 5-15P, 5-20P, 6-15P and 6-20P plugs
• Ideal where equipment or guests use mixed plug styles
• Saves space compared with mounting multiple inlets

Is the inlet built for outdoor use and harsh weather?

Yes — the housing and cover are created for exterior installation. The snap-fit, rubberized cap forms a tight seal to reduce moisture intrusion and the nylon and copper construction resists corrosion and wear in typical outdoor conditions.

• Water-resistant rubber cover protects against rain and snow
• Black nylon housing resists UV and weather exposure
• Copper conductors and 12AWG wiring for robust conductivity

What are the electrical and installation details I should know?

The inlet is rated for 20 amps at 125 VAC and ships with 12AWG wiring, giving a balance of current capacity and flexibility for common recreational and light industrial needs. Its flanged, flush-mount design fits a standard panel cutout so you can install without hand-wiring the cord.

• 20 A, 125 VAC rating suitable for many RV and outdoor loads
• Heavy-duty 12 AWG copper wiring and 20-inch extension lead
• Flanged mount requires a ~2-inch hole for quick, tool-friendly installation

Where can I use this inlet and what should I avoid?

This inlet is intended for devices and setups that match its voltage and amperage specifications, making it well suited to RV shore power, boats, trailers, garden buildings, and mobile workshops. Avoid using it with equipment that needs higher amperage or non-compatible voltages unless verified by the device manufacturer.

• Perfect for RVs, trailers, golf carts, boats, sheds, and cabins
• Works with generators and standard extension cords when properly matched
• Not for permanent high-amperage industrial mains beyond 20A rating

Who is this for? The stio 20A inlet is aimed at RV owners, boaters, van dwellers, and DIYers who want a compact, multi-plug shore power solution without complicated wiring. It’s also useful for rental properties, trailers, and small outbuildings where flexible plug compatibility and weather resistance are priorities. If you need a straightforward, mountable inlet that accepts multiple T-blade plugs and offers short, robust cording for reliable outdoor connections, this product delivers a convenient, low-fuss option.
