Which is better for running an RV air conditioner?

The WEN. Its 4800 surge watts and 4000 rated gasoline watts start and run a 13,500 BTU RV AC with headroom. The Pulsar's 4000 peak and 3200 rated watts leave little margin once other loads are on.

Is the WEN worth $243 more than the Pulsar?

Yes if you want electric start, a three-year warranty and about 800 more rated watts. If you only need to run a fridge, lights and a laptop, the Pulsar does that for less.

Which is easier to move?

The Pulsar at 55 lbs. The WEN is 78.5 lbs, though both have wheels and a telescoping handle.

How long does each run on propane?

WEN states about 12 hours at half load on a 20 lb propane tank. Pulsar does not publish a propane run time; its 8-hour figure is for gasoline at 50% load.

Both are rated 62 dB, but the WEN figure is at quarter load and the Pulsar figure is not tied to a load. Expect both to get louder as load rises, and Pulsar buyers report it exceeds 62 dB.

Do both have CO shutdown?

Yes. The Pulsar has a CO sensor and the WEN has the Watchdog CO Shutdown Sensor; both also have low-oil shutdown and overload protection.
