Stio 20A Shore Power Inlet

Check Price on Amazon

The Stio model combines a 20-amp, 125-volt inlet with a 5‑in‑1 T-blade adapter. The female side accepts several popular outlets including NEMA 1-15P, 5-15P, 5-20P, 6-15P, and 6-20P, making it adaptable for a range of devices. A 16-inch extension cord helps reach distant outlets or shore power pedestals. This unit uses copper wiring and a waterproof, pressure-fit cover to guard against rain and snow. Best for RV owners who need flexible adapter options in a single appliance. A potential limitation is the need for your connected devices to support the wide voltage range (110V–250V) for 6-15/6-20 configurations.

  • Best for mixed outlet scenarios: 5-in-1 compatibility reduces the need for multiple adapters.
  • Better for outdoor use thanks to the weatherproof cover and watertight design.

The compact dimensions (3.7″ x 3.3″ x 3.2″) and included stainless steel fasteners simplify mounting.

Buying Guide: Key Considerations For Choosing The Right RV Shore Power Plug

Power needs vary by RV size, intended use, and campsite availability. Consider the following when selecting a shore power inlet:

  • Current Rating: Choose 15A, 20A, or 30A based on your typical appliance load. Higher amperage handles more devices but requires compatible pedestals or generators.
  • Connector Type: NEMA configurations (1-15, 5-15, 5-20, L5-30P) determine compatibility with outlets at parks and marinas. Twist-lock L5 connectors provide a secure connection in windy or snowy conditions.
  • Cord Length: Ensure the included extension length fits your site layout. Longer cords increase flexibility but add bulk and weight.
  • Weatherproofing: Look for integrated covers, back covers, and robust housings. ETL or UL listings reinforce safety and build quality for outdoor use.
  • Installation Ease: Some models offer simple 2-inch hole mounting with straightforward wiring blocks. If you’re not comfortable with wiring, prefer models labeled as “easy install.”
  • All-in-One vs. Separate Components: 5-in-1 adapters reduce accessory clutter, but dedicated inlets with boot protectors provide rugged, all-weather protection.

Frequently Asked Questions

  5. What is a 5-in-1 adapter good for?
