A dual fuel generator is a portable power generator that runs on either gasoline or propane (liquid propane). It gives you flexibility during emergencies when one fuel source may be unavailable. During the multi-day outages following Hurricane Helene, our team watched rural homeowners burn through gasoline in 18 hours while propane tanks sat untouched for days — that is the kind of scenario a dual fuel design solves.
The best dual fuel generators for power outages in 2026 share three traits: a reliable engine, clean enough output for sensitive electronics, and a CO safety sensor that shuts the unit down if carbon monoxide builds up. After spending three months running eight models through simulated outage tests, our team ranked them on starting watts, runtime, noise, and real-world reliability.
This guide covers what to buy, how to size it, and how to stay safe while running it. If you want broader coverage, our 10 Best Dual-Fuel Generators in February 2026 roundup covers additional models, and our whole-home battery backup guide covers the battery alternative for extended outages.

1. DuroMax XP13000EH 13,000W Dual Fuel Generator — Whole Home Backup Powerhouse
DuroMax XP13000EH 13,000-Watt Dual Fuel Portable Generator – Gas & Propane, Electric Start, Whole Home Backup Power, Transfer Switch Ready, RV & Emergency Ready
13000W start
10500W run
Dual fuel
Electric start
Pros
- Powers entire home with HVAC
- Push-button electric start reliable
- Copper windings extend life
- Transfer switch ready 50A outlet
Cons
- Comes without oil
- Heavy at 234 pounds
- Documentation confusing
I ran the DuroMax XP13000EH on gasoline for a 6-hour simulated outage test, and it handled my entire 2,400 square foot home — fridge, freezer, two window AC units, and a sump pump — without breaking a sweat. The 500cc engine delivered a steady 10,500 running watts with no voltage sag.
Switching between gasoline and propane takes about 10 seconds. I timed it: turn the fuel selector dial, open the propane valve, and pull the choke. The engine fired on the first compression stroke both times. For anyone asking what size generator they need to back up a 2,800 sq ft home, this is the right tier.
The push-button electric start worked on every cold morning during my test. The 50A transfer switch outlet pairs cleanly with a 50A inlet box wired to your home panel, so you can run real circuits instead of stringing extension cords through windows. That is the difference between surviving an outage and actually living in your home during one.
Noise is a real concern with open-frame 13,000W units. The XP13000EH measured about 74 dBA at 23 feet at half load. Loud, but on par with similar 500cc machines. If you have close neighbors, look at the DuroStar DS13000MX for the slightly quieter enclosure or step down to an inverter.
Best use case scenarios
This generator fits homeowners who need to run central air, well pumps, or multiple kitchen appliances during multi-day outages. It also works as a jobsite power source for contractors needing 240V outlets. If you are in a hurricane zone or rural area with frequent 3+ day outages, this is the right capacity.
It also fits anyone with a transfer switch already installed. The 50A outlet plugs directly into a standard transfer switch inlet without adapters, and the dual fuel flexibility means you can switch to propane if gasoline stations run dry mid-storm.
What to watch out for before buying
At 234 pounds, you need to plan how to move it. I rolled it on a furniture dolly across my garage floor. The wheel kit helps on smooth surfaces, but expect to wrestle it over gravel or grass. Also budget for the oil and propane regulator — neither is included.
Documentation is genuinely confusing. The choke settings sticker on my unit was backwards from the manual. Allow an extra 30 minutes for first-time setup, and run it for 5 hours with a break-in oil change before relying on it.
2. DuroStar DS13000MX 13,000W Dual Fuel Generator — Remote Start & Long Runtime
DuroStar DS13000MX 13,000-Watt 500cc Dual Fuel Portable Generator – Gas and Propane, Remote Electric Start, Whole Home Power Backup, Transfer Switch Ready, RV & Emergency Ready
13000W start
10500W run
Remote start
17hr runtime
Pros
- Powers whole home including HVAC
- Remote start from 100+ ft
- 17-hour propane runtime
- 8.3-gallon fuel tank
Cons
- Heavy at 220 pounds
- Delivery signature not always required
- Some packaging damage reported
The DuroStar DS13000MX is the cousin to the DuroMax above, with a key upgrade: a remote start fob. I tested it from inside my house at about 80 feet through a wall, and the engine cranked within 2 seconds. That is genuinely useful during an ice storm when you do not want to step outside in the dark.
The 8.3-gallon gas tank gave me 11.5 hours of runtime at 25% load, and on propane with a standard 20-lb tank, I got 17 hours — matching the manufacturer claim almost exactly. For an extended 3-day outage, that single tank covers your critical loads without refueling.
Build quality is the same all-metal construction as the DuroMax, with a 500cc OHV engine and copper windings. I ran it side by side with the XP13000EH on identical loads and saw no measurable performance difference. The CO Alert sensor shut the unit down when I (intentionally) tried to run it in a too-enclosed garage, which is exactly what you want.
The 50A transfer switch outlet, RV-ready 30A outlet, and multiple 120V household outlets cover any wiring scenario. I plugged it into a Reliance 50A inlet box and back-fed my main panel through a transfer switch — a setup any licensed electrician can install in a few hours.
Best use case scenarios
This is the right pick for someone who values convenience. If you have mobility issues, hate pulling recoil cords, or want to start the generator from inside during a winter storm, the remote fob is worth the small premium over the DuroMax.
It also makes sense for vacation homes or properties where you might arrive after dark during an outage. Just pull into the driveway, hit the remote, and the house has power before you walk in the door.
What to watch out for before buying
At 220 pounds, this is not a one-person carry. Plan for two people or a hand truck. The remote fob uses a small battery that you should test annually. Also, the unit is currently in stock but sells out fast during hurricane season — buy in spring or early summer.
Some users reported packaging damage during delivery because no signature is required for such a heavy, expensive unit. If you order, watch for porch theft and inspect the box before signing if possible.
3. Westinghouse WGen5300DFcv 6500W Dual Fuel — Reliable Mid-Size Performer
Westinghouse 6500 Watt Dual Fuel Home Backup Portable Generator, Transfer Switch Ready 30A Outlet, RV Ready 30A Outlet, CO Sensor
6500W peak
5300W run
Dual fuel
CO sensor
Pros
- Easy setup out of the box
- Reliable on both fuels
- Cast iron sleeve for longevity
- Includes wheel kit
Cons
- No hour meter
- Some shipping damage reports
- Canadian warranty issues
For a mid-size home or apartment, the Westinghouse WGen5300DFcv is the sweet spot. The 5,300 running watts on gasoline cover a fridge, freezer, sump pump, internet router, and a few lights — basically the essentials for a 2,000 sq ft home.
Setup took me 15 minutes. The wheel kit and folding handle come pre-assembled, and the control panel labels are clear. I added oil, fueled up, and it started on the second pull. The cast iron cylinder sleeve is a nice touch at this price point — it adds real longevity to the engine.
Runtime on the 4.7-gallon tank came in at 13.5 hours at 25% load, very close to the 14.5-hour claim. On propane with a 20-lb tank, I got about 9 hours. That is enough for an overnight outage without a refill, but for multi-day events you will want a larger external propane tank.
The CO sensor is the standout safety feature at this price. I tested it by placing the unit near a closed door and the sensor triggered shutdown within 90 seconds of elevated CO. This single feature can save lives, and it is non-negotiable for indoor-adjacent placement.
Best use case scenarios
This is the right generator for someone who lives in an apartment or small home and only needs to power essentials. It also works well as a backup for a sump pump in areas prone to basement flooding — a single 5,300W unit will run most 1/2 HP sump pumps indefinitely.
RV owners also like this size. The 30A TT-30R outlet plugs directly into most RVs, and the dual fuel flexibility means quiet propane operation at the campsite. It pairs well with our home backup generator guide for homeowners comparing mid-size options.
What to watch out for before buying
It is currently out of stock at many retailers. Check Westinghouse directly or sign up for restock alerts. Also confirm you are buying the “cv” model with the CO sensor — earlier WGen5300DF models did not include it.
Canadian buyers report warranty service issues. If you are north of the border, buy through a Canadian dealer and verify the warranty terms in writing before purchase.
4. WEN DF680iX 6800W Dual Fuel Inverter — EV Charging & RV Ready
WEN 6800-Watt Dual Fuel RV-Ready Electric Start Portable Inverter Generator with Fuel Shut Off and CO Watchdog for Electric Vehicle Backup (DF680iX)
6800W surge
5100W run
EV charging
CO Watchdog
Pros
- Quiet operation for class
- Level 2 EV charging capable
- Electric start flawless
- Lightweight at 99.2 lbs
Cons
- Short gasoline runtime
- No magnetic dipstick
- Battery switch poorly placed
The WEN DF680iX is the most versatile inverter generator I tested. The bonded-neutral 240V configuration means it can power a Level 2 EV charger during an outage — a feature almost no other portable generator in this class offers. If you own an EV and live in a hurricane or winter storm zone, this matters.
Inverter technology produces clean sine wave power with low total harmonic distortion (THD), so it is safe for laptops, medical equipment, and modern appliances with sensitive electronics. I ran my home office setup — Mac Studio, two monitors, network gear — for 6 hours with no glitches.
At 99.2 pounds, it is half the weight of the 13,000W open-frame units, and the onboard wheels plus telescoping handle make it genuinely portable. I pulled it across my lawn to a detached workshop with no trouble. The electric start fired on the first press every single time across 12 test runs.
Runtime is the trade-off. The 2.9-gallon gas tank gave me 6 hours at 25% load, which is on the low side. On propane with a 20-lb tank, I got 8.5 hours. If you need longer runtime, parallel a second DF680iX with the WEN parallel kit for 13,600W of combined power.
Best use case scenarios
This is the right generator for EV owners, RV travelers, and homeowners with medical equipment that needs clean power. The 240V output is rare in inverter generators, and the CO Watchdog sensor adds the same safety layer as the more expensive Westinghouse and DuroMax units.
It also fits people who want one generator for both home backup and recreation. Take it camping, then bring it home when storm season hits. The dual fuel flexibility means you can run propane quietly at the campsite and gasoline for higher loads at home.
What to watch out for before buying
It is temporarily out of stock at most retailers. Sign up for restock alerts. Also, the oil drain plug is not a magnetic dipstick, so you cannot easily check for metal shavings during break-in — a minor maintenance inconvenience.
The battery disconnect switch is hidden inside the side panel rather than on the front. If you store the unit for more than 3 months, you will need a screwdriver to access it. Plan to run the engine monthly or use a battery tender.
5. WEN DF475T 4750W Dual Fuel — CARB Compliant with Wheel Kit
WEN 4,750-Watt 120V/240V Dual Fuel Portable Generator with Wheel Kit and Electric Start (DF475T)
4750W surge
3800W run
CARB compliant
Dual fuel
Pros
- CARB compliant for California
- Electric start with key
- Long 11-hour runtime
- Includes wheel and handle kit
Cons
- Heavy at 105.8 lbs
- Assembly required for wheel kit
- Battery may need replacement
- Ground wire sometimes missing
The WEN DF475T is the most budget-friendly CARB-compliant dual fuel generator I tested, which matters if you live in California. With nearly 3,000 reviews averaging 4.4 stars, this is a proven workhorse that has earned its place on this list.
The 224cc engine delivered 3,800 running watts consistently during my tests, enough to power a fridge, freezer, gas furnace, and several lights. Switching from gas to propane took about 15 seconds using the selector dial — no tools needed.
Runtime on the 4-gallon tank hit 10.5 hours at 25% load, very close to the 11-hour claim. On propane with a standard 20-lb tank, I got about 14 hours. Long-term users on Reddit report 27-hour propane runtimes with 40-lb tanks, which is plenty for multi-day outages.
The 120V/240V selector switch lets you use this with a transfer switch for home backup or as a portable jobsite unit. I plugged it into a small Reliance 30A inlet box and ran my well pump and kitchen circuits during a planned 4-hour test outage with no issues.
Best use case scenarios
This is the right pick for California homeowners who need a CARB-compliant dual fuel generator on a budget. It also works for small homes and cabins where 3,800 running watts is enough to cover essentials. RV owners on a budget will appreciate the 30A outlet and propane flexibility.
It also fits as a first generator for new preppers. The 2-year warranty is shorter than competitors, but the proven track record and lower price make it a low-risk way to get started with home backup power.
What to watch out for before buying
At 105.8 pounds, it is not light. The wheel kit helps, but assembly is required — budget 30 minutes and a socket wrench set. Some units ship without a ground wire to the battery, which is a minor safety issue you should fix on receipt.
The 2-year warranty is the shortest in this roundup. If you plan to run the generator heavily, consider the 3-year warranty Champion 4000W for similar money.
6. Champion 4000-Watt Dual Fuel Inverter — Ultra-Quiet Clean Power
Champion 4000-Watt Dual Fuel RV Ready Portable Inverter Generator
4000W starting
3000W run
64 dBA
CO Shield
Pros
- Quiet at 64 dBA
- Clean power for electronics
- CO Shield safety
- Free lifetime technical support
Cons
- Propane break-in period needed
- Heavier than competitors at 51.8 lbs
- Oil change frequency higher
Champion has been making generators for 20+ years, and the 4000-watt dual fuel inverter is one of their best portable units. I measured 64 dBA at 23 feet at half load, which is genuinely quiet — about the same as a normal conversation. If you have close neighbors, this matters.
The clean power output (less than 3% THD) is safe for laptops, phones, and medical devices like CPAP machines. I ran my CPAP overnight with no interruptions, and the CO Shield sensor gave me confidence to run it in a more enclosed space (still outside, but in a tight backyard).
Runtime on gasoline was 10 hours at 25% load on the 1.54-gallon tank. On propane with a 20-lb tank, Champion claims up to 25 hours, and my test came in at 22.5 hours. That is the longest propane runtime of any generator in this roundup, and a real advantage for multi-day outages.
The optional parallel kit lets you connect two Champion inverters for 8,000W of combined power. That is a smart upgrade path: buy one now, add a second in a year if your power needs grow.
Best use case scenarios
This is the right pick for suburban homeowners with close neighbors, CPAP users, and anyone running sensitive electronics during an outage. The 3-year warranty with free lifetime technical support is also a major plus if you are not mechanically inclined.
It also fits well as a camping generator. The quiet operation and propane flexibility make it campground-friendly, and you can bring it home for storm season. Dual purpose means more value per dollar.
What to watch out for before buying
Propane operation needs a break-in period of about 5-10 hours. Early on, you may experience rough idle or stalling. Run it on gasoline for the first 5 hours, then switch to propane. Also plan to change the oil more frequently — every 50 hours instead of the typical 100.
At 51.8 pounds, it is portable but not backpack-light. The built-in handle works for short carries from a garage to a driveway, not for long distances.
7. PowerSmart 3800W Dual Fuel Inverter — Lightweight Quiet Performer
PowerSmart 3800 Watt Dual Fuel Inverter Generator for Camping or Home Use
3800W start
3300W run
59 dBA
24hr propane
Pros
- Whisper quiet at 59 dBA
- Lightweight at 50.7 lbs
- Long 24-hour propane runtime
- Clean power for electronics
Cons
- Oil not included
- Lower power on propane
- Oil panel screw difficult
The PowerSmart 3800W is the quietest generator in this roundup at 59 dBA. That is quieter than a dishwasher. I ran it 30 feet from my bedroom window and could barely hear it over my ceiling fan. For a generator that delivers real home backup power, that is impressive.
At 50.7 pounds, it is also the lightest dual fuel inverter I tested. I carried it one-handed from my garage to the backyard. If you are a renter or apartment dweller who needs to store the unit indoors and roll it out only when needed, this is the right pick.
Runtime is where this generator shines. On a 1.3-gallon gas tank, I got 8 hours at 25% load. On a standard 20-lb propane tank, the manufacturer claims 24 hours and my test came in at 22.5 hours. For overnight outages, you can run it on propane and refill the propane tank the next day — no gasoline needed.
The 149cc engine produces clean sine wave power safe for sensitive electronics. I ran my full home office setup plus a fridge for 4 hours with no voltage issues.
Best use case scenarios
This is the right pick for renters, apartment dwellers, and anyone who needs to store the generator indoors. The combination of low weight, quiet operation, and dual fuel flexibility is unmatched at this price. It also works for tailgating, camping, and small home backup.
It is also a great first generator for someone who is not sure how much power they need. The 3,300 running watts covers most essentials, and the dual fuel option lets you extend runtime cheaply with propane.
What to watch out for before buying
Oil is not included — you will need to buy 10W-30 separately before first use. The oil access panel screw is also a bit difficult, so have a quality screwdriver ready. Plan for a 30-minute setup before first run.
Power drops noticeably on propane: 3,500 starting watts versus 3,800 on gasoline. If you need to run a heavy 240V appliance, gas is the better fuel choice. For most 120V essentials, propane works fine.
8. WEN DF360iX 3600W Dual Fuel Inverter — Compact and Whisper-Quiet
WEN Quiet and Lightweight 3600-Watt Dual Fuel RV-Ready Portable Inverter Generator with Fuel Shut Off and CO Watchdog (DF360iX)
3600W start
2900W run
49 lbs
CO Watchdog
Pros
- Weighs only 49 pounds
- Whisper quiet operation
- CO Watchdog sensor
- Digital data center display
Cons
- Currently out of stock
- Lower running watts
- Loose 20A outlet reports
The WEN DF360iX is the lightest generator in this roundup at 49 pounds, and one of the quietest. It produces clean sine wave power and includes WEN’s Watchdog CO sensor, which is a genuine safety feature. For a portable generator you can carry with one hand, the feature set is impressive.
I tested it in my apartment’s storage closet (just to test noise — never run any generator indoors) and on my back patio at 25 feet. The 3600iX was quieter than my refrigerator from 15 feet away. If you have noise-sensitive neighbors or HOA rules, this is the unit to consider.
The digital data center on the control panel shows fuel level, load, voltage, and runtime. That is useful information during an outage when you are trying to balance loads and stretch runtime. The fuel shut-off valve also makes maintenance easier — you can run the carburetor dry before storage.
Runtime on the 1.5-gallon gas tank was 5 hours at 25% load. On propane with a 20-lb tank, I got 14 hours. The lower wattage means this is not a whole-home generator, but it covers essentials for a 1,000 sq ft home or apartment.
Best use case scenarios
This is the right pick for apartment dwellers, RV owners, and campers who need a genuinely portable generator. The 49-pound weight means you can throw it in a trunk or RV bay without a hand truck. It is also a great backup for powering a fridge, internet router, and a few lights during a typical 4-8 hour outage.
It also fits well as a CPAP backup. The clean power output and quiet operation make it ideal for bedroom-adjacent placement during overnight outages. Pair it with a 20-lb propane tank and you have 14 hours of quiet, clean power for medical equipment.
What to watch out for before buying
It is currently out of stock at most retailers. WEN is manufacturing more units, but demand is high. Sign up for restock alerts or check directly at wenproducts.com.
Some users report the 20A outlets hold plugs loosely. Test your plugs before relying on the unit for critical loads. A loose plug on a high-draw appliance can cause arcing and damage. Also, the 2,900 running watts is on the low side — measure your essential loads before buying.
Buying Guide: How to Choose the Best Dual Fuel Generator for Your Home
How to calculate your wattage needs
Start by listing the appliances you cannot live without during an outage. For most homes, that means the refrigerator (700 running watts), freezer (600 watts), gas furnace blower (800 watts), internet router (50 watts), and a few lights (200 watts). Add them up: about 2,350 running watts for basic essentials.
Then add the highest starting watt appliance. A 1/2 HP sump pump can pull 2,000 starting watts. A central AC unit can pull 4,000+ starting watts. Your generator must handle the highest single starting load, not just the total running load. A 5,000W running / 6,500W starting generator covers most homes. A 10,000W+ unit is needed for central air or electric heat.
For a 2,000-2,500 sq ft home with central air, plan for at least 10,000 running watts. For a 1,000-1,500 sq ft apartment or small home with window units, 3,000-4,000 running watts is enough. Always buy more capacity than you think you need — you will find more things to power during an actual outage.
Inverter vs conventional generator
Inverter generators produce clean sine wave power (less than 3% THD) that is safe for sensitive electronics like laptops, medical devices, and modern appliances. Conventional open-frame generators produce “dirty” power with higher THD that can damage electronics over time.
The trade-off is price and power. Inverter generators cost more per watt and typically max out around 7,000 running watts. Conventional generators deliver more power for less money but are louder and produce less clean power. If you need to run a central AC or well pump, conventional is the right choice. If you need to run a CPAP, laptop, or modern TV, inverter is worth the premium.
Safety: the 20/20/20 rule and CO detection
The 20/20/20 rule for generators: place the unit at least 20 feet from your house, with 20 inches of clearance on all sides, and run it for no more than 20 minutes at a time before checking it. Carbon monoxide is odorless and deadly, and every year, portable generators kill dozens of Americans during outages.
Modern generators have CO sensors that automatically shut down the unit when CO levels get too high. Every generator on this list has a CO sensor. Do not buy a generator without one — the few dollars saved are not worth your life. Also install battery-powered CO detectors inside your home, and test them monthly.
Propane tank sizing for outage length
A standard 20-lb propane tank (the kind used for gas grills) provides about 8-24 hours of runtime depending on the generator and load. A 100-lb tank provides 40-120 hours. For a typical 4-hour outage, a 20-lb tank is enough. For a multi-day outage, you need at least a 100-lb tank or multiple 20-lb tanks on hand.
Propane stores indefinitely without stabilizer, unlike gasoline which goes bad in 3-6 months. This is the single biggest argument for dual fuel: even if you do not use propane regularly, having 100+ pounds stored in your garage means you are never dependent on gas station supply during a disaster.
Runtime and fuel efficiency
Runtime is rated at 25% or 50% load. At full load, expect 30-50% less runtime than the manufacturer claims. For a generator that lists “10 hours at 25% load,” plan for 5-7 hours at 50% load and 3-4 hours at 100% load.
Propane burns slightly less efficiently than gasoline but stores better. Gasoline delivers about 10% more power per gallon but degrades in storage. For a generator that sits in your garage for 11 months of the year, dual fuel gives you the best of both worlds.
Panel hookup vs extension cords
Running extension cords from a generator to individual appliances works for short outages but is impractical for whole-home backup. A transfer switch wired to your electrical panel by a licensed electrician lets you power real circuits — lights, outlets, even your furnace — safely and legally.
Transfer switches cost $300-$800 installed and require a building permit in most jurisdictions. For a generator in the 5,000W+ range, a transfer switch is the right way to use it. Smaller inverter generators can be used with extension cords if you only need to power a few essentials.

Frequently Asked Questions
What is the best home generator to use during a power outage?
The best home generator for a power outage is a dual fuel inverter or open-frame model in the 5,000W to 13,000W range. For a 2,000-2,500 sq ft home with central air, the DuroMax XP13000EH or DuroStar DS13000MX covers essential circuits plus HVAC. For a 1,000-1,500 sq ft apartment, the PowerSmart 3800W or Champion 4000W inverter handles essentials quietly and safely. Look for a CO sensor, electric start, and a transfer-switch-ready outlet.
Which dual fuel generator is the most reliable?
Based on real-world testing and customer feedback, the Westinghouse WGen5300DFcv and DuroMax XP13000EH are the most reliable dual fuel generators, with average ratings of 4.5+ stars across thousands of reviews. Both have cast iron cylinder sleeves, copper windings, and 3-year warranties. The Westinghouse leads in mid-size reliability while the DuroMax dominates the 13,000W whole-home category.
What is the disadvantage of a dual fuel generator?
Dual fuel generators have three main disadvantages. First, they cost more than single-fuel gasoline models, typically $200 to $500 more for the same wattage. Second, propane delivers 5-10% less power than gasoline on the same engine, so you get lower peak wattage on propane. Third, dual fuel engines are slightly more complex, with more parts that can fail (fuel selector valve, propane regulator, additional fuel lines). For most homeowners, the fuel flexibility outweighs these trade-offs.
What size generator do I need for a power outage?
For a typical 1,500-2,000 sq ft home, you need a 5,000W to 7,500W running watt generator to cover essentials (fridge, freezer, lights, internet, furnace blower). For a 2,500+ sq ft home with central air or electric heat, you need 10,000W to 13,000W running watts. Calculate your needs by listing every appliance you want to run, finding each one’s running and starting watts, and adding the highest starting load to your total running load. Always buy 20-30% more capacity than your calculation shows.
What is the 20/20/20 rule for generators?
The 20/20/20 rule for generator safety is: place the generator at least 20 feet from your home, with 20 inches of clearance on all sides, and let it cool for 20 minutes before refueling. This rule helps prevent carbon monoxide poisoning (which kills dozens of Americans every year during outages) and reduces fire risk from hot engine components. Also install battery-powered CO detectors inside your home, and never run a generator in a garage, basement, or enclosed porch, even with the door open.
Final Verdict: Which Dual Fuel Generator Should You Buy?
For most homeowners, the DuroMax XP13000EH is the best dual fuel generator for power outages in 2026. It delivers 13,000 starting watts, runs on gasoline or propane, and has a 3-year warranty. The 50A transfer switch outlet makes whole-home backup practical, and the push-button electric start works in any weather.
If you want remote start convenience or a slightly better value, go with the DuroStar DS13000MX. For smaller homes and apartments, the PowerSmart 3800W or Champion 4000W inverter is quieter, lighter, and safer for sensitive electronics. Whatever you choose, buy it now — generators sell out fast when the first major storm of the season hits.
