That sounds obvious, but generator listings make it easy to get distracted by the biggest wattage number on the page. That number is usually the gasoline starting output. It does not tell you how much power the generator can deliver continuously on propane, and it definitely does not tell you whether the machine can handle your well pump, central air conditioner, refrigerator, and everything else at the same time.
I built this list around the numbers that matter on propane. I also separated the big 120/240-volt home-backup units from the smaller 120-volt inverter generators. They solve different problems, and treating them as interchangeable would be bad advice.
The Short Version
The Westinghouse WGen11500TFc is the best overall choice if you want serious 120/240V backup power and already have—or plan to install—a safe way to connect a generator to your panel. The Champion 201176 is my favorite step-down option because it gives you inverter power without giving up 240V. If you only need the refrigerator, lights, internet, and a few smaller loads, the Generac iQ5200DF or WEN DF360iX makes more sense than dragging home a 200-plus-pound generator.
My Take
For a typical American homeowner looking for a real outage machine, I would start with the Westinghouse WGen11500TFc. It has enough propane output to give you options instead of forcing you to choose between the refrigerator and every other important circuit. If you do not need that much power, the Champion 201176 is the better-balanced machine. It is still a large generator, but its inverter output and 120/240V panel make it a strong fit for modern homes.
The smaller Generac iQ5200DF and WEN DF360iX are good tools, but you need to understand what you are buying: both are 120V-only generators for selected essentials. They are not substitutes for a 240V home-backup unit.
The Five Generators at a Glance
| Generator | Propane starting watts | Propane running watts | Voltage | Best fit |
|---|---|---|---|---|
| Westinghouse WGen11500TFc | 13,500W | 10,500W | 120/240V | High-output home backup |
| DuroMax XP13000HXT | 12,000W | 9,500W | 120/240V | Heavy-duty tri-fuel backup |
| Champion 201176 | 9,000W | 6,525W | 120/240V | Home circuits plus inverter power |
| Generac iQ5200DF | 4,700W | 3,500W | 120V | Mid-size essentials backup |
| WEN DF360iX | 3,500W | 2,600W | 120V | Portable essentials backup |
These are the manufacturers’ published propane figures. Starting watts only last long enough to help motors and compressors get moving. Running watts are what you have available once everything is operating.
1. Westinghouse WGen11500TFc — Best Overall
| Propane output | 13,500 starting / 10,500 running watts |
| Fuel choices | Gasoline, propane, or natural gas |
| Home connection | 120/240V with L14-30R and 14-50R outlets |
| Noise | 74 dBA published rating |
My Take
The Westinghouse WGen11500TFc is the one I would put at the top of the list for a house, not a campsite. On propane, it can deliver 10,500 watts continuously. That gives you far more breathing room than a 3,000- or 4,000-watt inverter when a refrigerator compressor, well pump, or furnace blower kicks on.
It has the outlets you want to see on a serious backup generator: an L14-30R and a 14-50R, both with 120/240V output. Connected through the right transfer equipment, it can cover a useful group of household circuits. It may also start some central air-conditioning systems, but do not buy it based on that assumption alone. Check the AC unit’s locked-rotor or starting requirement and talk to an electrician about the complete load. Some systems need a compatible soft start; some are simply too large.
The tri-fuel setup is a real advantage. Propane is easy to keep on hand, gasoline gives you the highest output, and natural gas can be useful during a long outage if your home has the correct supply and connection. Remote start is convenient, but remember that you still need to inspect the area before starting the generator.
Best for: Homeowners who want high-output 120/240V backup and are willing to set it up correctly.
2. DuroMax XP13000HXT — Best Heavy-Duty Alternative
| Propane output | 12,000 starting / 9,500 running watts |
| Fuel choices | Gasoline, propane, or natural gas |
| Home connection | 120/240V with L14-30R and 14-50R outlets |
| Propane tank | DuroMax suggests at least a 40-pound cylinder |
My Take
The DuroMax XP13000HXT is built for the same kind of buyer as the Westinghouse: someone who wants real home-backup output, 240V capability, and more than one fuel option. It gives up 1,000 running watts to the Westinghouse on propane, but 9,500 watts is still a lot of usable power.
DuroMax gives you plenty of ways to connect equipment. The panel has four standard 120V outlets, a 30-amp 120V outlet, an L14-30R, and a 14-50R. It also includes remote start and a natural-gas hose. The frame is all metal, and the generator weighs about 240 pounds before you add fuel or accessories.
Here is the detail I would not ignore: DuroMax recommends a 40-pound propane cylinder at minimum. Do not expect a half-full grill tank to feed a 500cc engine at a heavy load, especially on a cold morning. A large generator needs a fuel supply that can vaporize propane fast enough to keep up.
Best for: Buyers who want a rugged high-output machine and can support it with a larger propane supply.
3. Champion 201176 — Best 120/240V Inverter
| Propane output | 9,000 starting / 6,525 running watts |
| Power type | Open-frame inverter with less than 3% THD |
| Home connection | 120/240V with L14-30R and 14-50R outlets |
| Propane runtime | Up to 12 hours at 25% load on a 20-pound tank |
My Take
The Champion 201176 is the most interesting generator here. It is large enough to produce 120/240V power through 30-amp and 50-amp outlets, but it also uses inverter technology and keeps total harmonic distortion below 3%. That is a useful combination if your outage plan includes modern electronics along with pumps, refrigeration, and normal household circuits.
On propane, you get 6,525 running watts. That is enough for a solid essentials setup, but it is not enough to turn on every large appliance and forget about load management. You will still want to bring high-draw equipment online one item at a time.
Champion calls this an open-frame inverter, and that is exactly how you should think about it. It is more efficient and quieter than the traditional generator used in Champion’s comparison, but the published noise level is 72 dBA from 23 feet. Your neighbors will know it is running. This is not one of those suitcase-style inverters you can barely hear across a campsite.
Best for: Homeowners who want cleaner inverter output and still need 120/240V service.
4. Generac iQ5200DF — Best Mid-Size Enclosed Inverter
| Propane output | 4,700 starting / 3,500 running watts |
| Power type | Fully enclosed inverter with less than 3% THD |
| Voltage | 120V only |
| Starting system | Electric start with recoil backup |
My Take
The Generac iQ5200DF makes sense when you want to keep the important 120V stuff alive without buying a generator that takes up half the garage. It delivers 3,500 running watts on propane, uses a fully enclosed inverter design, and starts with a button instead of making you pull a recoil cord every time.
A reasonable load plan might include a refrigerator, a few lights, a router, chargers, a television, and another modest appliance. The exact combination depends on the labels on your equipment and the starting surge from anything with a motor. Add loads one at a time instead of treating 3,500 watts like an unlimited budget.
There is one big limitation: this is a 120V generator. It will not run a 240V well pump, electric dryer, range, or other 240V appliance. The 30-amp locking outlet does not change that. If 240V equipment is part of your outage plan, move back up to the Champion, DuroMax, or Westinghouse.
Best for: Homeowners who need clean 120V power for a carefully chosen group of essentials.
5. WEN DF360iX — Best Lightweight Pick
| Propane output | 3,500 starting / 2,600 running watts |
| Power type | Dual-fuel inverter |
| Voltage | 120V only, including a TT-30R RV outlet |
| Weight | 49 pounds |
My Take
The WEN DF360iX is the generator on this list that you can realistically carry instead of roll. It weighs 49 pounds and makes 2,600 running watts on propane. That is nowhere near enough for the whole house, but it can be plenty for a refrigerator and a small group of carefully managed 120V loads.
The inverter output is a good match for laptops, phones, televisions, and networking equipment. You also get two regular household receptacles, a TT-30R RV outlet, USB ports, and a 12V DC outlet. WEN’s fuel-shutoff feature lets the engine use the fuel left in the carburetor before it stops, which is useful when you switch back to storage after running gasoline.
This model uses recoil start, so it is not as convenient as the push-button Generac. It is also 120V only. Buy it because you want a compact emergency machine, not because you expect it to act like the Westinghouse.
Best for: Refrigeration, communication gear, lighting, and other small loads when portability matters.
How Much Generator Do You Actually Need?
Forget the phrase “whole-house generator” for a minute. Make a list of what you need during a blackout. For most people, that starts with the refrigerator, freezer, lights, internet, furnace blower, sump pump, or well pump. Air conditioning may be on the list if you live somewhere hot, but it can change the size of generator you need in a hurry.
Look at the equipment label or owner’s manual for running watts and starting watts. Motors and compressors need a short burst of extra power when they start. Add the running load for everything you want on at the same time, then make sure the generator can absorb the largest starting surge without being pushed to its limit.
A Simple Sizing Plan
- List the circuits and appliances you truly need.
- Mark each item as 120V or 240V.
- Add the running watts for loads that will operate together.
- Allow for the largest motor or compressor starting surge.
- Leave some headroom. Do not build a plan that keeps the generator at its limit for hours.
- Have a licensed electrician confirm the inlet, transfer equipment, breaker capacity, neutral setup, and local code requirements.
120V Versus 240V
This is where a lot of buyers get burned. The Westinghouse, DuroMax, and Champion produce 120/240V power. The Generac and WEN produce 120V only.
A 120V generator can keep a refrigerator, lights, electronics, and other normal plug-in equipment running. It cannot power a 240V well pump, electric dryer, range, or similar appliance. A 30-amp outlet does not automatically mean a generator makes 240V—look at the actual voltage specification.
Never plug a generator into a household outlet to feed power backward through the wiring. Backfeeding can injure a utility worker, start a fire, or destroy equipment. If you want to power circuits in the panel, use approved transfer equipment installed for that purpose.
What Changes When You Run on Propane?
You usually get less power
The same generator normally produces fewer running watts on propane than on gasoline. Do not guess at a 10% or 15% loss. The drop is different from model to model, which is why every number in this guide uses the published propane output.
A small cylinder can become the bottleneck
Propane has to turn from liquid into vapor before the engine can burn it. Cold temperatures, low fuel level, a small tank, and a heavy load all make that harder. This matters much more on a 500cc home-backup generator than it does on a small inverter. Follow the tank recommendation in the manual instead of assuming every generator will be happy on a grill cylinder.
Runtime depends on how hard you work the generator
Published runtime is measured with a particular tank and load. Your results will change with temperature, altitude, cylinder fill, regulator condition, and how often appliances cycle. A generator running a refrigerator and a few lights will last much longer than the same generator feeding pumps and air conditioning.
Safety: Do Not Take Shortcuts
Carbon Monoxide Can Kill in Minutes
Never run a portable generator inside a house, garage, basement, crawlspace, shed, porch, or carport—even if a door is open. The U.S. Consumer Product Safety Commission says to operate it outdoors at least 20 feet from the home, with the exhaust pointed away from buildings, doors, windows, and vents. A CO shutoff is a backup feature. It does not make indoor or near-home operation safe.
- Install working carbon-monoxide alarms on every floor and outside sleeping areas.
- Follow the manual for wet-weather operation. Do not build a box around the generator that traps heat or exhaust.
- Check the hose, regulator, cylinder, cords, and plugs before every use.
- Store and transport propane cylinders upright and follow local fire codes and the cylinder supplier’s instructions.
- Read the manual and test the entire setup before storm season—not after the lights go out.
Common Questions
Is propane better than gasoline for a generator?
Propane is convenient for emergency storage and does not leave old liquid gasoline sitting in the carburetor. Gasoline usually gives you more output, while propane needs a cylinder and may have trouble vaporizing fast enough in extreme cold or under a heavy load. A dual-fuel or tri-fuel generator lets you choose based on the situation.
Can one of these generators run my entire house?
The two largest models can cover a substantial group of household circuits, but no responsible answer is possible without knowing your loads. Electric heat, central air, water heaters, ranges, dryers, and well pumps can use a huge amount of power. Size the generator from the appliance data, not from the square footage of the house.
Can I use a regular 20-pound propane tank?
A 20-pound tank works with many small and mid-size generators, and manufacturers often use one for their runtime tests. Large generators may need more fuel-delivery capacity. DuroMax specifically suggests at least a 40-pound cylinder for the XP13000HXT. Follow the manual for your exact model.
Do I need an inverter generator?
An inverter is a good choice when clean power and variable engine speed are priorities. The Champion, Generac, and WEN in this guide are inverter models. The Westinghouse and DuroMax publish total harmonic distortion at 5% or less, but you should still check the requirements of sensitive equipment before connecting it.
Can I run a generator in the garage if the door is open?
No. An open garage door does not make generator exhaust safe. Run the generator outdoors at least 20 feet from the house and point the exhaust away from any opening.
Final Verdict
Buy the Westinghouse WGen11500TFc if you want the strongest all-around home-backup option here. It has the most propane running power, proper 120/240V connections, and three fuel choices.
Choose the Champion 201176 if 6,525 running watts will cover your plan and you want inverter output with 240V capability. If your goal is simpler—keep the food cold, the lights on, and the family connected—the Generac iQ5200DF is the better mid-size machine, while the WEN DF360iX is the easy-to-carry option.
Whatever you buy, set it up before you need it. Make a load list, arrange enough propane, test the generator outdoors, and get the home connection handled by someone who knows the electrical code. That work matters more than any feature printed on the box.
