Westinghouse WGen9500DF
Probably the most-reviewed big portable on the internet — 24,000+ ratings averaging 4.7 — and the default r/Generator answer for 'cheap whole-house backup through an interlock.' 9,500 running watts on gasoline (8,500 on propane), a 50-amp outlet, remote-start key fob, and a 12-hour tank for around a grand is a spec sheet nothing else matches. Owners routinely run entire homes including central AC during hurricanes. It is not subtle: expect 75+ real-world dB, a 211-lb frame, and open-frame vibration. The complaint file is proportionate to the sales volume: occasional oil leaks and QC escapes out of the box, a Westinghouse support line that owners describe as slow to days-long, and carb gumming if stored wet. The current 'DFc' revision adds a CO sensor. Buy it, change the skimpy break-in oil early, and store it dry.

Westinghouse WGen11500TFc Tri-Fuel
The r/Generator power-user pick: hook it to your home's natural gas line through a quick-connect and you have effectively unlimited runtime without storing a drop of gasoline — the practical middle ground between a portable and a $12,000 standby install. On gasoline it makes a huge 11,500 running watts; the honest math is the NG derate to 9,500 running watts, still enough for most whole homes via the 50A outlet and an interlock. Remote start, CO sensor, and a 9.5-gallon tank round it out. Owner notes: NG performance depends on your line pressure — undersized gas plumbing causes surging and hard starts, the most common complaint thread — plus it's a 230-lb beast, mid-70s dB loud, and Westinghouse support remains the weak link. Registered owners report solid 3-year warranty coverage when they persist.

Westinghouse iGen4500
The RV community's favorite non-Honda: 3,700 running watts, a genuine 52 dB at quarter load, a telescoping suitcase handle, and an 18-hour economy-mode runtime that owners verify on long weekends. The digital display with remaining-runtime readout and the remote-start fob are the features people mention unprompted, and at half the cost of Honda's discontinued EU3000 it became the default. It starts most 15k BTU RV ACs, though owners at altitude or in high heat add a soft-starter to be safe. Grievances from long-term threads: the rear wheels are small for gravel campgrounds, the recoil backup start is awkwardly placed, carb gumming after storage is the top reliability complaint (fuel shutoff use is essential), and Westinghouse's parts/support pipeline can be slow. The DF dual-fuel variant had a fuel-filter leak recall in 2020 — this gas model wasn't affected.

Firman
Firman T07571 Tri-Fuel
The Costco tri-fuel that made natural-gas backup a thousand-dollar proposition. The T07571 runs 7,500 watts on gasoline, 6,750 on propane, and 5,500 on natural gas, ships with both LP and NG hoses in the box, and has a 50-amp outlet — which is why r/Generator treats it as the default budget answer to 'I want to hook a portable to my gas meter.' Owners praise the honest hardware: electric start, 8-gallon tank, sturdy 213-lb frame, and a 3-year warranty that beats Predator's 90 days. The recurring complaints: Firman customer service is slow — weeks-long waits for warranty parts are the most common thread — NG output is a real 27% derate, it's a loud 74 dB open frame, and low NG line pressure causes surging just like every NG portable. Costco's return policy is frequently cited as the real warranty.
