How We Chose These Generators
Every generator on this list was selected from our scored database of portable generators currently priced below $1,000. We ranked candidates by their overall score, which factors in running wattage, power quality (THD), fuel flexibility, runtime efficiency, noise level, safety features like CO sensors and GFCI outlets, warranty length, and included accessories. We then applied a value lens specific to this price bracket: watts-per-dollar ratio, what comes in the box versus what you have to buy separately, and whether the generator punches above its price class in any meaningful way. We also considered fuel type diversity, giving extra credit to dual-fuel and tri-fuel models that offer resilience during emergencies when gasoline may be scarce. Inverter generators were evaluated alongside conventional models but judged within their own class, since they deliver cleaner power and quieter operation at a lower wattage-per-dollar ratio by design. Every generator here carries at least a 3-year warranty, and most include essential accessories like oil, a tool kit, and a wheel kit. For a deeper understanding of the difference between inverter and conventional generators, see our comparison guide.

What to Look for in a Generator Under $1000
- Calculate your watts-per-dollar ratio. Divide the running wattage by the price to compare raw value. On this list, the DuroStar DS13000MXT leads at roughly 10.5 watts per dollar, while the Honda EU2200i delivers about 1.8 watts per dollar. Conventional generators always win this metric, but inverter generators compensate with cleaner power and quieter operation.
- Prioritize dual-fuel or tri-fuel capability. During emergencies, gasoline stations may be closed or have long lines. Propane stores indefinitely and burns cleaner, while natural gas connects to your home's supply for virtually unlimited runtime. At this price point, most top models offer at least dual fuel, so there is little reason to settle for gasoline-only unless you specifically want an inverter like the Honda EU2200i or Cummins Onan P2500i.
- Check what is included in the box. Some generators include oil, a battery, a wheel kit, a propane hose, and even a cover, while others require separate purchases that add 50 to 150 dollars to your total cost. The Westinghouse WGen9500DF and Firman T04073 are standouts for included accessories.
- Match THD to your devices. If you plan to power laptops, phones, CPAP machines, or other sensitive electronics, you need an inverter generator with THD below 5%. The WEN DF680iX at 1.2% THD, the Honda EU2200i at 3%, the Cummins Onan P2500i at less than 3%, and the Westinghouse iGen2800DFc at less than 3% are the safe choices. Conventional generators on this list range from 11% to 25% THD and can damage sensitive devices. For more on this topic, read our guide on why some generators kill appliances and others don't.
- Consider noise level for your use case. If you are camping, tailgating, or running a generator in a residential area, noise matters enormously. The Honda EU2200i at 48 dBA is quieter than a normal conversation, while the Westinghouse WGen9500DF and DuroStar DS13000MXT at 74 dBA are as loud as a vacuum cleaner. Many campgrounds enforce 60-65 dBA limits. Check our quietest generators guide for more options.
- Look for a CO shutdown sensor. Carbon monoxide poisoning is the leading cause of generator-related deaths. Models with automatic CO shutdown sensors, including the Westinghouse WGen5300DFc, iGen2800DFc, DuroStar DS13000MXT, Firman T04073, Honda EU2200i, Pulsar PGL9000BCO, WEN DF680iX, and Firman H03655, add a critical layer of protection. This feature should be a strong priority for any generator used near living spaces.
- Verify outlet compatibility before buying. If you need to connect to a transfer switch, you need an L14-30R (30A) or 14-50R (50A) outlet. For RV use, look for a TT-30R outlet. For basic appliance use, standard 5-20R duplex outlets work. The Westinghouse WGen9500DF and DuroStar DS13000MXT offer the most complete outlet panels with both 30A and 50A 240V connections.
- Do not overlook warranty length. Every generator on this list carries a 3-year warranty, which is above the industry average. This is a strong indicator of manufacturer confidence in the product. Always register your generator after purchase to activate the full warranty coverage.
Important Safety Notes
⚠️ WARNING: NEVER run or NEVER operate a generator indoors, in a garage, in a basement, or in any enclosed or partially enclosed space. Generators produce carbon monoxide, an odorless, colorless gas that can kill in minutes. Always operate your generator outdoors only, at least 20 feet away from windows, doors, and vents, with the exhaust pointing away from any occupied structure.
⚠️ WARNING: NEVER connect or NEVER plug a generator directly into a wall outlet, breaker panel, or any household wiring. This creates a dangerous backfeed condition that can electrocute utility workers, neighbors, and anyone who contacts energized power lines. Always use a properly installed transfer switch, connected by a licensed electrician, to power your home's circuits from a generator.
⚠️ WARNING: Store all fuel in approved containers designed for that specific fuel type, and keep fuel storage away from living areas, ignition sources, and the generator itself while it is running or hot. Gasoline vapors are heavier than air and can travel along the ground to ignition sources. Allow the generator to cool completely before refueling.
⚠️ WARNING: Even generators equipped with CO shutdown sensors are not a substitute for proper placement. These sensors are a backup safety measure, not a license to operate in enclosed spaces. Always follow the 20-foot rule and ensure adequate ventilation around the generator.
⚠️ WARNING: Ground your generator according to the manufacturer's instructions and local electrical codes, especially when connecting to a transfer switch or using the generator on a job site. Improper grounding can create shock hazards.

FAQ
What can I run with a generator under $1000?
It depends entirely on the model's running wattage. A 1,800 to 2,200-watt inverter generator like the Westinghouse iGen2800DFc, Honda EU2200i, or Cummins Onan P2500i can run a refrigerator, a few lights, and charge devices. A 3,650 to 5,300-watt model like the Firman H03655, Firman T04073, Westinghouse WGen5300DFc, or WEN DF680iX can power a refrigerator, sump pump, window AC unit, lights, and multiple devices simultaneously. The 8,100 to 10,500-watt models like the Pulsar PGL9000BCO, Westinghouse WGen9500DF, and DuroStar DS13000MXT can handle a central air conditioner alongside other major loads. Use our guide on how to size a generator for your home at /guides/how-to-size-a-generator-for-your-home-without-guessing-or-overbuying to add up your specific needs before buying.
Is an inverter generator worth the extra cost per watt?
Yes, if you need to power sensitive electronics like laptops, gaming consoles, or medical devices. The inverter generators on this list (Westinghouse iGen2800DFc, Honda EU2200i, Cummins Onan P2500i, and WEN DF680iX) produce clean power with THD at or below 3%, while conventional generators on this list range from 11% to 25% THD. Inverters are also dramatically quieter at 48 to 64 dBA versus 63 to 74 dBA for conventional models. However, if you only need to run motors, lights, and basic appliances, a conventional generator gives you two to three times more running wattage per dollar spent. See our guide on inverter generators vs conventional generators at /guides/inverter-generators-vs-conventional-generators-differences-and-benefits for a detailed comparison.
What does dual-fuel or tri-fuel mean, and is it worth it?
Dual-fuel generators run on gasoline and propane. Tri-fuel models like the DuroStar DS13000MXT and Firman T04073 add natural gas as a third option. This flexibility is extremely valuable during emergencies when one fuel type may be unavailable. Propane stores indefinitely without degradation and burns cleaner than gasoline, reducing engine carbon buildup and maintenance. Natural gas connects to your home's existing gas line for virtually unlimited runtime. The trade-off is slightly lower wattage output on propane (typically 10 to 20% less) and natural gas (typically 15 to 30% less) compared to gasoline. At this price point, most top-scoring models offer at least dual-fuel capability, so there is little reason not to get it.
How long will these generators run on a single tank?
Runtime varies significantly by model, tank size, and load. At 50% load on gasoline, generators in this guide range from 4 hours (Honda EU2200i with its 0.95-gallon tank) to 14 hours (Firman T04073 and Firman H03655 with their 5-gallon tanks). At 25% load, the DuroStar DS13000MXT reaches 17 hours, the Westinghouse WGen5300DFc delivers 14.5 hours, the Westinghouse iGen2800DFc provides 12 hours on gasoline or an impressive 38 hours on propane, and the Cummins Onan P2500i runs for 10 hours. If you plan to run a generator overnight during an outage, look for models with at least 8 to 10 hours of runtime at 50% load, or choose a model with propane capability for extended runtime.
Can I use these generators for RV camping?
Yes, but check for a TT-30R outlet, which is the standard 30-amp RV receptacle. The Westinghouse WGen5300DFc, Westinghouse iGen2800DFc, WEN DF680iX, Firman H03655, and DuroStar DS13000MXT all include RV-ready outlets or TT-30R receptacles. The Firman T04073 includes an RV adapter instead. For campground use, noise level matters enormously: the inverter models at 48 to 64 dBA are far more campground-friendly than conventional models at 63 to 74 dBA. Many campgrounds enforce noise limits of 60 to 65 dBA, so check the rules before bringing a conventional generator. See our guide on best generators for RV camping at /guides/best-generators-rv-camping for more campground-specific recommendations.
Do I need a transfer switch to use a generator at home?
If you want to power your home's built-in wiring and circuits through the breaker panel, yes, you absolutely need a transfer switch installed by a licensed electrician. NEVER connect a generator directly to a wall outlet or breaker panel, as this creates a dangerous backfeed condition that can electrocute utility workers and neighbors. You can run extension cords directly from the generator's outlets to individual appliances without a transfer switch, but this limits you to whatever you can plug in directly. For whole-house backup, look for generators with a 30-amp L14-30R or 50-amp 14-50R outlet. On this list, the Westinghouse WGen9500DF, DuroStar DS13000MXT, Westinghouse WGen5300DFc, Pulsar PGL9000BCO, Firman T04073, and WEN DF680iX all include L14-30R outlets, and the WGen9500DF and DS13000MXT also include 50-amp 14-50R outlets.
What is the difference between starting watts and running watts?
Running watts (also called rated watts) is the continuous power a generator can sustain indefinitely. Starting watts (also called peak or surge watts) is the brief burst of extra power available for 1 to 2 seconds when a motor-driven appliance like a refrigerator, air conditioner, or sump pump first starts up. Always size your generator based on running watts for your total simultaneous load, and make sure the starting watts can handle your largest single appliance's startup surge. For example, the Westinghouse WGen9500DF provides 9,500 running watts continuously but can briefly deliver 12,500 watts to start a large motor. Our guide on understanding starting and running watts at /guides/understanding-starting-running-watts explains this in more detail with real-world examples.
Which generator under $1000 gives me the most watts per dollar?
The DuroStar DS13000MXT leads the pack at 10,500 running watts, delivering roughly 10.5 watts per dollar spent. The Westinghouse WGen9500DF is close behind at 9,500 running watts for the same price, yielding about 9.5 watts per dollar. The Pulsar PGL9000BCO offers 8,100 running watts at a lower price, giving it a competitive watts-per-dollar ratio as well. Among inverter generators, the WEN DF680iX stands out with 5,100 running watts at a mid-range price. Keep in mind that watts per dollar is just one metric. Fuel flexibility, noise level, THD, safety features, and included accessories all factor into true value.
