Which one can run a central air conditioner?

Neither reliably runs a 3-ton central AC. The Champion's 6,000 running watts and 50A socket can carry a large transfer-switch circuit or a well pump; the iQ's 3,000 watts suits a fridge, furnace blower, lights, and a few small appliances.

The iQ, rated below 60 dB. The Champion is rated 62 dB, with its description citing 69 dBA at 23 ft, which is louder than normal speech.

Is the Champion worth $150 more?

Only if you need the extra 3,000 running watts or the 50A outlet. For RV and essential-circuit backup, the iQ does the job for less and is easier to move.

How long does each run at half load?

The iQ runs about 13 hours on gasoline and 16 hours on a 20 lb propane tank. The Champion runs up to 8.5 hours on its 3.6-gallon tank.

Do both shut off for carbon monoxide?

Yes. The Champion uses CO Shield and the iQ uses COsense; both stop the engine at unsafe CO levels. Neither replaces an indoor CO alarm, and both must run outdoors.

Can I monitor either from my phone?

Only the iQ, through WiFi and the Mobile Link app. The Champion has a digital control center on the unit showing hours, voltage, load, and frequency, plus Type-C charge ports.
