GEARit 30 Amp RV Extension Cord 25 ft — NEMA TT-30P to L5-30R Locking, 10/3 AWG SJTW Outdoor

The GEARit 30 Amp RV Extension Cord (25 ft) is a heavy-duty locking extension that adds safe, weather-resistant reach between your RV or generator and the shore power connection.

If a short pedestal or an awkward campsite layout forces you to compromise where you park, a reliable extension cord restores flexibility. This 25-foot, 30-amp cable uses 10/3 AWG copper conductors inside an SJTW-rated jacket and mates a NEMA TT-30P plug to an L5-30R locking receptacle. It’s built to carry full 30-amp, 125V loads for campers, travel trailers, and portable generators while resisting outdoor wear and keeping the plug joint locked against vibration and wind.

How does this cord keep power steady across 25 feet?

The cord uses 10/3 AWG copper conductors sized for 30-amp service, which minimizes voltage drop and heat under typical RV loads. The thick conductors plus the quality insulation let it carry the intended current without the losses common to thin, consumer-grade extension cords.

• 10/3 STW copper wiring rated for sustained 30A use.
• SJTW jacket resists moisture, sunlight and temperature swings.
• Spec-correct connectors avoid mismatched fittings that cause resistance.

Will the connectors stay secure during travel and windy conditions?

Yes — the cord pairs a NEMA TT-30P male plug with an L5-30R locking female receptacle, a combination designed to lock together and resist coming loose. The locking feature keeps the connection seated through vibration, towing movement, and gusts.

• NEMA TT-30P plugs into standard 30A RV pedestals.
• L5-30R locking receptacle secures the joint against pull and wobble.
• Durable strain relief at both ends reduces connector stress during handling.

Is this cord suitable for outdoor and seasonal use?

The outer SJTW jacket and STW conductors are chosen for outdoor durability, so the cable stands up to rain, sun exposure, and cold-weather flexibility. It’s ETL listed for safety and constructed to resist abrasion and common campsite wear.

• SJTW-rated jacket for weather and UV resistance.
• Robust construction for repeated seasonal packing and unpacking.
• ETL listing provides independent safety verification.

Where will this extension be most useful?

This cord is made for RV owners and others who need a reliable 30-amp extension outdoors. Use it to reach a distant shore power pedestal, place a generator away from the rig, or bypass an awkward hookup at a campsite or job site.

• Campground shore power extensions when the pedestal is too close or poorly sited.
• Generator-to-camper hookups where parking distance matters.
• Driveway or temporary power runs for outdoor projects and events.

Who is this for? RV and trailer owners, seasonal campers, and contractors who rely on dependable 30-amp shore power will find this GEARit extension cord useful. It suits anyone needing extra reach without sacrificing safe current capacity: campers who want flexible site selection, weekend warriors who park generators away from occupied areas, and pros who need a rugged, weather-ready extension for outdoor power tasks. If you need a cord that’s sized for true 30A loads, resists outdoor conditions, and stays locked in place, this 25-foot GEARit extension is built for those needs and backed by product support should you have connection or setup questions.
