Is $379 a good price for this generator?

It is low for a 3200W inverter generator; most name-brand units in this class cost several hundred dollars more. Two stores list it new, and $379 at Walmart as of November 5, 2026 is the best new price.

Can it run an RV air conditioner?

A typical 13,500 BTU RV air conditioner needs about 2,800 to 3,500 surge watts to start. The 4000W peak covers most of them, and the 30A RV outlet plugs in directly.

Can I use it in California?

No. The listing says it is not carb-compliant, so it is not legal for sale or use in California.

Does it have electric start?

No. It is pull-cord start only, so you start it by hand each time.

Can I connect two units together?

Yes. It is parallel ready, so a second compatible unit can double the output, though the parallel cable is usually sold separately.

How loud is it really?

The rated 62 dB is roughly normal-conversation level at close range. Expect it to rise under heavy load, and keep it away from tent walls and campsite neighbors.
