The VEVOR 50 Amp Generator Cord and Power Inlet Box Kit connects a portable generator to a home or RV through a fixed inlet on the outside wall. Instead of running extension cords through a window or door, the cord plugs into a weather-protected box, so backup power during an outage is simpler to hook up. The kit pairs a 50-foot cord with the inlet box.
What is in the kit
VEVOR lists two main parts: the 50-foot generator cord and a power inlet box with a flip cover. A carrying strap and a storage bag are also included, so the cord can be rolled up and kept in a garage, a shed or an RV storage bay. The model is given as RV50H/SS2-50R+LSTK06.
Reading the plug and cord specs
The cord has a NEMA 14-50P male plug at one end, the common 50A plug found on many generator outlets and RV pedestals. At the other end is a twist-lock NEMA SS2-50R female connector, which mates with the SS2-50P male inlet on the box. The twist-lock style turns a quarter turn to lock, which helps keep the connection from being pulled apart.
The cable is STW type with 6/3+8/1 AWG conductors. In general, that means three 6-gauge conductors plus one 8-gauge conductor, and a lower AWG number means a thicker wire able to carry more current over a distance. VEVOR rates the cord for up to 50 amps and describes the conductors as pure copper inside flame-retardant PVC that resists heat and UV.
The power inlet box
The inlet box has a pre-drilled design and a detachable plug, which VEVOR says allows installation without extra tools for the mounting step. The casing has a rust-resistant coating against wind, rain and dust. An indicator light on the flip cover lights up when power is connected, making it easy to see at a glance whether the generator feed is live, day or night.
A note on installation: wiring an inlet into a home's electrical panel is normally work for a licensed electrician, and usually needs a properly installed transfer switch or interlock so the generator can't feed power back into the grid. Local codes and the manufacturer's instructions apply.
Twist-lock handle and outdoor use
The male plug has a handle so it can be pulled out without yanking on the cable. The female end's twist-lock mechanism is described as slip-free and as keeping dust and water from reaching the contacts. VEVOR says the cord is built to cope with rain, wind, snow, soil and rocks, and lists the cord and box as ETL certified. ETL is a safety listing from a recognized testing laboratory, which is a good thing to look for on any electrical accessory.
Who it suits
This kit is aimed at owners of a portable generator with a 50A outlet who want a tidy connection for emergency power at home or at an RV. Fifty feet gives some freedom to place the generator away from the building, which is wise because generators should always run outdoors with plenty of ventilation.
What to check before you buy
- Confirm your generator has a 50A NEMA 14-50R outlet that matches the cord's 14-50P plug.
- Check your electrical setup, including the transfer switch or interlock, with a licensed electrician.
- Measure the distance between where the generator will sit and the wall where the inlet box will go.
- Make sure the generator's wattage and amperage suit what you plan to power.
- Look at the mounting location for the box and the hole pattern.
- Follow local codes and the manual for installation and use.
