Which is better for RV camping?

Both have a 30A RV outlet and run on propane. The WEN has push-button start and a fuel gauge, which helps at a campsite. The ERAYAK is 46 lb lighter, which matters if you lift it in and out of a bay.

Is the WEN worth $141 more?

Yes if you value electric start, a digital fuel display, and the larger 212cc engine. No if you mostly care about weight and price; the ERAYAK delivers the same 3500W gasoline running watts for less.

Which runs longer on a tank?

The WEN lists 8.5 hours at half load on gasoline and 9 hours on propane from a 2.2-gallon tank. ERAYAK does not publish a half-load runtime for its 2.25-gallon tank, so compare its fuel consumption figure of 550 g/kWh if runtime is critical.

Can I run a refrigerator on either?

Yes. Both are inverter generators with clean sine wave output and about 3500 running watts on gasoline, enough for a fridge compressor plus essentials. The WEN's larger engine gives more surge headroom.

Close. The WEN rates 58 dBA at quarter load at 22 feet. The ERAYAK rates 58 dBA at 7 meters and 60.5 dB(A) at half load, so the WEN is likely quieter under load.

Can I parallel two units?

The ERAYAK has a built-in parallel interface for pairing two 4500W units. WEN does not list a parallel connection for the DF450i.
