Which is better for whole-home backup?

The Pulsar. Its 9,500 running watts on gasoline and 50A outlet can feed a transfer switch; the Erayak's 3,500 watts covers only a few circuits.

Which is quieter for camping?

The Erayak at 62 dB at 25% load. The Pulsar is rated 74 dB, loud enough to bother nearby campsites.

Can the Erayak run a 30A RV?

Yes, it has a 30A RV outlet and 3,500 running watts on gasoline, enough for one air conditioner and basics. A second AC needs the Pulsar.

Is the Pulsar worth the extra money?

If you need 240V or whole-home power, yes: $929.99 at Walmart as of November 3, 2026 buys nearly three times the running watts. If you only charge devices and run a fridge, the smaller inverter is enough.

Which lasts longer on a tank?

The Pulsar, with an 8-gallon tank and about 13 hours at 50% load on gasoline. The Erayak's fuel capacity and runtime are not stated.

Will the Pulsar damage electronics?

It is a conventional generator without inverter output, so plug sensitive electronics into a surge protector or UPS. The Erayak's low THD is the safer choice for computers.
