Our take on the 50 Amp Generator Extension Cord 50ft - 12500W 6AWG Heavy Duty NEMA 6-50R/P SWT Cable for Generator, Welder, RV - ETL Listed with Storage Bag

This is a 50-foot, 6 AWG extension cord with a NEMA 6-50 plug and outlet, rated 50 amps, 250 volts and 12,500 watts. The heavy-gauge copper handles high-draw loads like generators, welders and RV hookups, and the SWT jacket is built for outdoor use in rain, sun and humidity. A light on the female end confirms live power, and a molded handle helps with plugging and unplugging. It is ETL listed and ships with a storage bag and cable tie. Against thinner 8 or 10 AWG cords, the 6 AWG conductors cut voltage drop over 50 feet, which matters for welders and large generators.

Questions and answers

Will this plug into a standard RV pedestal?
No. It uses NEMA 6-50 plugs on both ends. Most RV pedestals use NEMA 14-50, so you need an adapter or a 14-50 cord.
Can it run a welder?
Yes, if your welder uses a NEMA 6-50 plug and draws 50 amps or less. The 6 AWG conductors are sized for that load over 50 feet.
Is it safe for outdoor use?
The SWT jacket is made for outdoor conditions and the cord is ETL listed. Keep connections off wet ground and out of standing water.
How is this different from an 8 AWG cord?
Thicker 6 AWG copper carries more current with less voltage drop over the same length, which matters for high-draw tools and long runs.
What comes in the box?
The 50-foot cord, a storage bag and a cable tie.
