Which is better for home backup?

The Westinghouse. Its 9,500 running watts and 14-50R outlet feed a transfer switch and large 240V loads. The Erayak's 3,500 watts covers lights, a fridge and a few small appliances.

The Erayak at 62 dB at 25% load. The Westinghouse is rated 90 dB at 6 feet, which is loud for a campsite or close neighbors.

Can the Erayak run sensitive electronics?

Yes. Its inverter keeps total harmonic distortion at 0.2%-1.2%, which is safe for laptops, TVs and phones. The Westinghouse is a conventional generator without that rating.

Is the Westinghouse worth the extra money?

If you need whole-house watts, electric start and a 50A outlet, yes. At $999.00 at Walmart as of November 3, 2026, it costs more but does far more work. For RV or tailgating use, the lighter Erayak fits better.

Which is easier to move?

The Erayak at 55.12 lbs. The Westinghouse is much heavier and relies on its never-flat wheels and handle, so one person will struggle on stairs or a truck bed.

Do both run on propane?

Yes. The Westinghouse makes 9,500 running watts on propane, the same as gas. The Erayak drops to 3,150 running watts on propane from 3,500 on gas.
