VEVOR 50 Amp Generator Cord and Inlet Box Kit: specs and who it suits

The VEVOR RV50H/SS2-50R+LSTK06 is a kit that pairs a 10 ft, 50 amp generator cord with a power inlet box. The box mounts on the outside of a building, so a portable generator can be plugged in from outdoors and feed power inside during an outage. It is also aimed at RV emergency power.

What is in the kit

The kit has three main parts: a cord with a NEMA 14-50P male plug on the generator end, a twist-lock NEMA SS2-50R female connector on the other end, and the inlet box itself. VEVOR says the set supports up to 50A and 12,500W. The inlet box has pre-drilled holes and detachable knockouts, which are the round tabs that pop out where wiring enters the box.

What the cable gauge means

The cord uses STW cable with 6 AWG conductors for the three main wires and an 8 AWG conductor for the fourth. In the AWG system a smaller number means a thicker wire, and thicker wire carries more current with less heat and voltage drop. Six-gauge copper is a common size for 50 amp runs. VEVOR says the pure copper core gives steady transmission with minimal loss, and that the flame-retardant PVC jacket resists bending, rain and extreme temperatures. The "STW" marking generally denotes a thermoplastic cable intended for hard, weather-exposed service.

The inlet box

VEVOR describes the box as weatherproof, with a flip cover and a rust-resistant coating meant to shield the connection from wind and rain. An LED indicator lights automatically when the box is powered, so the status can be checked at night. The interior is described as roomy, which matters because 6 AWG wire is stiff and needs space to bend during wiring.

The twist-lock connector

Plain plugs can work loose or pull out. A twist-lock connector is turned a quarter turn after insertion so it stays seated. VEVOR says this gives a tight connection that keeps out dust and water, and the male plug has an ergonomic handle to make plugging and unplugging easier.

Installation and wiring

VEVOR says no drilling or extra tools are needed for the box itself, thanks to the pre-drilled holes and knockouts. Connecting the box to a home's electrical system is a different matter. It usually involves the main panel and a transfer switch or interlock device, and local electrical codes typically require a licensed electrician and a permit. Follow local codes and the manufacturer's manual.

Who it suits

It suits homeowners who keep a portable generator for outages and want a fixed outdoor connection point, and RV owners who need a short heavy-duty cord for backup power. Anyone who only needs to run a few appliances may find a standard extension cord enough.

What to check before you buy

• Generator outlet: confirm that your generator has a 14-50R receptacle, or that you have a suitable adapter.
• Generator output: check the generator's rated amps and watts. The cord's capacity is a ceiling, not a promise of what the generator supplies.
• Home connection: check what your area requires for connecting a generator to a house, including a transfer switch or interlock.
• Length: 10 ft is short; measure from where the generator will sit to where the inlet box will be mounted.
• Mounting spot: check the wall surface, the clearance around the box and where the generator may be run.
• What's in the box: confirm that the cord, connector, inlet box and any fasteners are all included.

The short version

• A 10 ft generator cord and power inlet box kit, rated by VEVOR for up to 50A and 12,500W.
• STW cable with a 6 AWG pure copper core, a NEMA 14-50P plug and an SS2-50R twist-lock connector.
• Weatherproof box with a flip cover, rust-resistant coating and a power-on LED.
• Pre-drilled holes and knockouts for mounting; ETL Listed per the listing.
• Home wiring should follow local codes and the manual, usually with a qualified electrician.
