Which portable generators have a built-in RV-ready outlet?

Answered by RV Parts Giant · Upland, CA · October 31, 2026

Short answer: Ten generators we stock list an RV-ready outlet or panel, from Westinghouse, Champion, DuroMax, WEN, Firman and KingChii. Only the KingChii names it as 30A. A listing that only says "for RVs" does not promise that outlet, so check the panel before you buy a cord.

These are the generators in our range whose listing states an RV-ready outlet.

Generator	Starting / peak watts	Running watts	Fuel	Type
Westinghouse WGen5300sc	6,600	5,300	Gas	Electric start
Westinghouse WGen5300DFcv	6,500 gas, 5,800 propane	5,300 gas, 4,800 propane	Dual	Recoil start
Westinghouse WGen3600DFcv	4,650	3,600	Dual	Recoil start
Champion 4,750W	4,750	3,800	Dual	Portable, electric start
Champion 4,550W	4,550	3,650	Gas	Portable, wireless remote start
Champion 4,000W	4,000	3,000	Gas	Inverter, under 49 lb, 64 dBA at 23 ft
DuroMax HX	5,500	4,500	Dual	Electric start
WEN 5,600W	5,600	4,500	Dual	Electric start, transfer-switch ready
Firman 4,125W	4,125	3,300	Dual	Inverter, electric start, "RV-ready control panel"
KingChii 4,500W	4,500	Not listed	Gas	Inverter, "30A RV-ready outlet"

"For RVs" is not the same claim

Many inverter generators are described as good for RV trips, including the Westinghouse iGen range, the Champion 4,500W and 6,500W inverters, the WEN DF480iX and the DEWALT 5,600W. Those listings do not state an RV outlet. They may still run your RV through a cord or adapter, but check the outlet panel in the manual or send us the model before you plan on plugging straight in.

Confirm the outlet shape before you buy a cord

Apart from the KingChii's 30A, our listings say "RV-ready" without giving a rating, and none of them names the receptacle. So look at the panel photo or manual for the model you want:

Straight three-prong TT-30R: your RV's 30-amp plug goes straight in.
Twist-lock L5-30R: you need an L5-30P to TT-30R cord or adapter between the generator and the RV.

More watts do not always reach the RV

A 30-amp RV connection tops out at 30 amps x 125 volts, or 3,750 watts. If your RV is on a 30-amp outlet, a generator with 5,300 running watts still gives the RV no more than that through the outlet. The 3,000-watt Champion and 3,300-watt Firman sit below that figure, so their own running watts are the limit.

Add up what will run at once, and compare it with the generator's running watts rather than its peak figure. On a dual fuel model, use the propane figure if you plan to run on propane.
