GEARit 30 Amp RV Extension Cord 100 ft — 10/3 STW NEMA TT-30, Waterproof Heavy-Duty

GEARit’s 100 ft 30 Amp RV extension cord is a heavy-duty, weatherproof 10/3 STW power cable with NEMA TT-30P to TT-30R ends designed to deliver full 30A/125V performance across long runs for campers and travel trailers.

When you need dependable shore power without adapters or voltage drop, this 100-foot 10/3 OFC copper cable bridges the gap between pedestal and RV. Built with a thick outdoor-rated jacket, sealed connector boots, and true 30 amp NEMA TT-30 connectors, the cord is engineered to handle campground conditions and heavy electrical loads so your AC, microwave, and converter run reliably.

How does this cord maintain full 30 amp power over 100 feet?

The cable uses 10 AWG, 10/3 STW oxygen-free copper conductors sized to minimize voltage loss across the entire 100-foot span. That gauge supports the full 30A / 125V / 3750W capacity without the noticeable sagging performance smaller wires produce.

• 10/3 OFC (oxygen-free copper) conductors for low resistance
• STW-rated insulation for outdoor durability and heat resistance
• Supports full 30A / 125V / 3750W continuous load
• Designed to prevent browning out at peak draw

Will this cord survive wet or rough campsite conditions?

Yes — sealed connector boots and a thick weatherproof jacket keep moisture and dirt away from contacts, and the outer jacket resists abrasion from gravel, concrete, and drag across pads. It stays flexible across temperature swings so it’s easier to handle in cold mornings and hot afternoons.

• Sealed plug and socket boots block water intrusion
• Heavy-duty STW outer jacket protects against cuts and wear
• Engineered flexibility for cold- and heat-resistant handling
• Suitable for gravel, mud, concrete, and wet conditions

What devices and vehicles is this cord compatible with?

This cord is fitted with NEMA TT-30P (male) and TT-30R (female) 3-prong connectors, the standard for 30 amp RV shore power. It plugs directly into RV pedestals and camper inlets without adapters and works with a wide range of mobile and stationary equipment requiring 30 amp service.

• Travel trailers, fifth wheels, and many motorhomes with TT-30 inlets
• Pop-up campers and small RVs using 30A shore power
• Portable generators and temporary 30A power setups
• Food trucks, jobsite tools, and large outdoor equipment requiring 30A

How does GEARit make this cord easier to use and store?

At 100 feet, the cord balances reach and manageability: it’s long enough to access distant pedestals while remaining flexible for coiling and storage. The molded connectors are ergonomically shaped for grip, and the jacket resists kinking so you can deploy and pack the cord quickly.

• Molded connectors for secure, comfortable handling
• Flexible jacket reduces kinks and tangles during use
• Designed for straightforward coiling and storage between trips
• Available in multiple lengths to suit different setups

Who is this for? If you camp in sites with variable pedestal distances, run heavy-draw appliances in your RV, or need a reliable 30 amp cable for generators, food trucks, or yard equipment, the GEARit 30 Amp RV Extension Cord 100 ft is built for those demands. It fits owners who prioritize full-load performance, outdoor durability, and dependable waterproof connections without adapters. Choose this if you want a long, heavy-duty 30A cord that’s made to withstand campground conditions while delivering stable power.
