Westinghouse and DuroMax both sell high-output dual-fuel generators for home backup. Westinghouse emphasises convenience features; DuroMax emphasises raw power per dollar. Here is how they compare.
The brands at a glance
Westinghouse
Westinghouse Outdoor Power Equipment licenses the historic Westinghouse name for a line of portable generators and inverters. The brand is known for features such as remote electric start, CO sensing and well-specified inverters, often at competitive prices.
DuroMax
DuroMax is known for high-output, heavy-duty generators at aggressive prices, including dual-fuel and tri-fuel models. Its XP series is popular with buyers who want maximum watts per dollar for home backup.
Head-to-head comparison
| Factor | Westinghouse | DuroMax |
|---|---|---|
| Lineup | iGen inverters, WGen open-frame, dual fuel | Dual fuel, tri-fuel, high-output open-frame, some inverters |
| Fuel options | Gasoline, propane (dual fuel) on many models | Gasoline, propane, natural gas on tri-fuel |
| Controls / app | Remote start key fobs on many models | Mostly manual; electric start common |
| Typical warranty | Typically 3-year limited (check model) | Typically 3-year limited on many models (check model) |
| Price position | Value to mid | Value, high watts per dollar |
Westinghouse wins on convenience and inverter refinement; DuroMax wins on output per dollar.
How sizes and prices line up
Both brands sell across similar size classes. Runtime depends mostly on tank size and load, so compare like-for-like classes and check the manufacturer’s quoted runtime at 25% and 50% load.
| Generator class | Typical street price range | Tank size | Typical runtime at 50% load |
|---|---|---|---|
| 2,000-2,500W inverter | $450-1,200 | ~1-1.2 gal | ~4-8 h |
| 3,500-4,500W open-frame | $400-800 | ~3.5-4.5 gal | ~9-12 h |
| 7,500-9,500W open-frame | $800-1,400 | ~6-7 gal | ~8-11 h |
| 12,000W+ dual/tri fuel | $1,200-2,000+ | ~8 gal | ~8-10 h |

Inverter or open-frame: which type fits?
Every brand in this comparison sells both types, and the type you choose matters more than the badge on the tank. Inverter generators produce clean, stable power that is safe for laptops, TVs and modern furnace controls, run much quieter, and throttle down at light loads to save fuel. Open-frame generators deliver far more watts per dollar and are the practical choice for whole-house backup through a transfer switch.
| Factor | Inverter | Open-frame |
|---|---|---|
| Typical noise (at 23 ft) | ~50-60 dBA | ~68-75 dBA |
| Power quality | Low distortion, electronics-safe | Higher distortion on budget models |
| Price per running watt | ~$0.25-0.60 | ~$0.10-0.20 |
| Common sizes | 1,000-4,000W | 3,500-15,000W |
A good rule: pick an inverter for camping, RVs and running sensitive electronics; pick an open-frame dual-fuel unit when you need to power a fridge, well pump and furnace at once.
Sizing: how many watts do you need?
Generators are sized by running watts, with extra starting (surge) watts for motors. List what you will run at the same time, add up the running watts, then add the single largest start-up surge on top. That total, plus about 10-20% headroom, is your target.
| Appliance | Running watts (approx.) | Starting watts (approx.) |
|---|---|---|
| Refrigerator | ~700 | ~2,200 |
| Sump pump (1/2 hp) | ~1,000 | ~2,000 |
| Window AC (10,000 BTU) | ~1,200 | ~1,800 |
| Furnace blower (1/3 hp) | ~700 | ~1,400 |
| Lights, TV, internet | ~500 | ~500 |
Those essentials add up to about 4,100 running watts, plus the fridge’s roughly 1,500W extra start-up surge, so a 6,000-7,500W-class generator covers them comfortably. For camping or a few outlets, a 2,000-3,500W inverter is enough.
Safety and placement
Carbon monoxide is the biggest risk with any gas generator. Run it outdoors only, at least 20 feet from the house with the exhaust pointed away from doors, windows and vents, and never in a garage, even with the door open. Choose models with automatic CO shutoff where possible and install battery CO alarms inside. Connect to home circuits only through a transfer switch or interlock installed by a licensed electrician, which prevents dangerous backfeed onto utility lines.
