Which Backup

On power it's a coin flip.

If you need the power, get the Generac.

These two are close enough that the deciding factors are small ones.

Running power is nearly identical, 3,000W for the Champion and 2,900W for the WEN, so look at what each one has and doesn't.

The 4500 is the stronger generator: 500 more running watts on gasoline, push-button start, and a noise figure Champion lists 3 dB lower.

Both are rated 1,900 running watts, so power won't decide this.

On numbers these are nearly twins: 1,900W against 1,850W running, and 11 hours against 11.5 at 1/4 load.

They're the same generator.

On paper the Westinghouse does more: 2,550W surge against 2,200W, 11 hours at 1/4 load against 8.1, plus a TT-30R RV outlet and USB ports.

The iGen2800DFc adds propane, a CO sensor and more peak power (2,800W against 2,550W).

They're the same machine with a different outlet panel.

On paper they're close on power: both start at 4,500W, and running watts are 3,600W for the WEN and 3,500W for the Champion.

The WEN has the power edge: 4,000W running against 3,500W.

It's power and outlets against weight.

The 56432i is the stronger one: about 24% more running power (3,600W against 2,900W), and WEN lists it 3 dB quieter at 1/4 load.

The Pulsar has more starting surge (4,000W against 3,600W) and a CO shutoff.
