Which is better for powering an RV?

The Champion 3800W. It has a dedicated TT-30 RV outlet, electric start, and 3800W running on gasoline versus 3500W for the Erayak. The Erayak is lighter to load, but you start it by pull cord.

Which one is quieter?

The Erayak lists 62 dB at 25% load. Champion does not publish a noise figure for this model, so the Erayak is the safer bet if quiet running is the priority.

Is the Champion worth extra money?

If prices are close, yes. You get electric start, CO Shield shutoff, more running watts, and a 3-year warranty. The Erayak only wins on weight and noise.

Can either run sensitive electronics like a laptop or TV?

Both are inverter generators. The Erayak publishes low THD of 0.2%-1.2%, which is clean enough for electronics. Champion does not list a THD figure for this model.

Which lasts longer on a tank?

Champion publishes up to 14 hours at 50% load on its 4.7 gal tank, or 10.5 hours on a 20 lb propane tank. Erayak does not list runtime, so Champion is the only one you can plan around.

Do both run on propane?

Yes. Champion runs 3420W on propane and includes a 6.6 ft hose with regulator. Erayak runs 3150W on propane. Champion also lists natural gas as a power source in its specs, which is unusual for a portable.

3800W Electric Start Dual Fuel Generator (CARB) vs Erayak 4500W Dual-Fuel Inverter Generator

Buy the Champion 3800W for RV use, home backup, or cold-weather starts: it has more running watts on both fuels, electric start with a battery, CO Shield, and a 3-year warranty. The Erayak 4500W is lighter at 55 lbs and quieter on paper, but it lists manual recoil start and no CO shutoff.
