POWGRN 30 Amp to 50 Amp RV Adapter Cord 12 inch Green

POWGRN’s 12-inch 30 amp to 50 amp RV adapter converts a TT-30 30A inlet to a 14-50 50A outlet, offering a compact, weather-resistant link for safely powering appliances from a 30A pedestal.

This heavy-duty adapter lets RV owners and campers use 50‑amp devices from a 30‑amp shore power connection without rewiring or bulky converters. Built with 10 AWG conductors, a flame-retardant PVC jacket and an ergonomic grip, the cord is designed to withstand outdoor exposure, simplify hookups, and maintain reliable conductivity for up to 3,750 watts at 125 volts.

How does this adapter handle outdoor conditions?

The POWGRN adapter is made for exposure to sun, rain and freezing temperatures, with a waterproof construction and materials rated to resist brittle failure in cold. Seals and heavy-duty jacketing minimize moisture intrusion and abrasion when connecting at campgrounds or marinas.

• IP-style weather resistance for rain and splashes
• PVC sleeve resists UV, abrasion and heat
• Operational down to -40°C for cold-weather use
• Compact 12" length reduces cable drag and tripping hazards

Will this adapter safely carry power for RV appliances?

Yes—the internal conductors are pure copper 10 AWG, sized to support a continuous load up to the adapter’s rated 3,750 watts. The unit is ETL listed, and the flame‑retardant jacket adds an extra layer of fire-safety protection where cords meet outlets.

• 10 AWG pure copper for low resistance and better conductivity
• Rated 30A, 125V, 3,750W for typical RV loads
• ETL listing for electrical safety compliance
• Heat-resistant materials reduce degradation over time

How easy is it to plug, unplug and store the adapter?

Both ends feature molded ergonomic grips that make plugging and unplugging effortless even with gloves or in tight spaces. The short 12" length keeps the adapter out of the way and simplifies storage in small compartments or a toolbox.

• Ergonomic handles on plug and inlet for improved leverage
• 12-inch length minimizes clutter and tangling
• Lightweight, compact form for onboard storage
• Robust strain reliefs protect connection points

What electrical connections does this adapter provide?

The adapter converts a NEMA TT‑30P 30‑amp male connection to a NEMA 14‑50R 50‑amp female receptacle, allowing you to temporarily power 50‑amp devices from a 30‑amp source. It does not alter circuit capacity—loads must remain within the 30A source limit.

• NEMA TT‑30P (30A male) to NEMA 14‑50R (50A female)
• Does not increase available amperage from the shore power
• Ideal for powering select 50A equipment on a limited basis
• Designed for short-term adapter use, not permanent rewiring

Who is this for? RV owners, campgrounds, vanlifers and boaters who need a compact, dependable way to plug 50‑amp appliances or equipment into a 30‑amp shore power pedestal will find this POWGRN adapter useful. It’s best for temporary hookups where weather resistance, safe conductivity and easy handling matter most—especially when space is limited or a quick, reliable connection is required.
