Portable Inverter Generators
Portable Inverter Generators for Clean, Quiet Backup Power
Portable inverter generators do more than keep the lights on. They convert engine output into stable electricity electronically, which protects laptops, TVs, medical devices, and appliance control boards from damaging voltage spikes. Power quality is measured as total harmonic distortion, and a guide from Bailey Line Road reports that the best conventional generators sit around 5 percent while inverters come in under 3 percent. Because the engine speeds up and slows down with demand, an inverter portable generator typically burns less fuel at light loads and runs quieter than a fixed-speed machine. This collection offers 18 models, from compact campsite units to 28,000-watt home backup powerhouses, so you can find the right portable generator inverter for your needs.
Compact and Mid-Size Inverter Generators
For camping, tailgating, and essential outage power, the DuroMax XP2300iH and the Cummins Onan P2500i are easy to carry and simple to store. Step up to the Cummins Onan P4500i, P4500iDF, or P5000iDF EFI when you want to run a refrigerator, lights, and a window air conditioner together. The DuroMax XP7000iH, the XP7000iHT, and the DuroStar DS8000iX add enough capacity for a furnace blower or well pump alongside your essentials. Each inverter generator portable option here is built to move easily from the garage to the job site.
High-Output Inverter Generators for Home Backup
When one machine has to carry the whole house, look at the DuroMax 9500-watt and 11,000-watt dual fuel inverters, the DuroStar DS14000iX, and the 16,000-watt DuroMax units. The DuroMax XP28000IH and XP28000IHT reach 28,000 watts, giving large homes with central air and multiple heavy loads serious inverter-clean power. Many DuroMax models list a CO Alert that shuts the engine down if carbon monoxide builds up, which adds a layer of protection when you run one of these inverter portable generators during a long outage.
Dual Fuel, Tri-Fuel, and RV-Ready Options
Most of the larger inverter generators in this collection run on gasoline and propane, and tri-fuel models such as the XP7000iHT, XP11000iHT, XP16000iHT, and XP28000IHT add natural gas so you can use whichever fuel is easiest to find. The Anker SOLIX Smart Generator 5500 tri-fuel unit is built to work with E10 home backup systems, and the Cummins Onan QG 7000i DF is designed for commercial mobile and RV use.

Every order ships free within the continental USA, and our USA-based experts can help you match a model to your load.
Frequently Asked Questions
Can a portable inverter generator run a refrigerator, furnace, or sump pump?
Yes, as long as the generator's starting watts cover the surge these motors draw when they kick on. Compressors and pumps can briefly pull two to three times their running wattage, so check the label on each appliance and size the generator to the largest startup load plus everything else running at the same time. Start the biggest motor first and add smaller loads afterward.
Can I connect an inverter generator to my home's electrical panel?
Yes, with a transfer switch or interlock kit and a generator inlet installed by a licensed electrician. Never plug a generator into a wall outlet to feed the house, because the power can flow back onto the utility line and endanger line workers. Larger models with 240V outlets can power hardwired loads such as a well pump or central air through a properly sized transfer switch.
How long will an inverter generator run on a single tank?
Runtime depends on tank size, fuel type, and how much power you draw. Inverter engines slow down at light loads, so the same tank lasts much longer when you are running a few lights and a refrigerator than when you are near full capacity. Propane stores longer than gasoline without breaking down, which is worth considering if the generator will sit unused between storms.
Do inverter generators need regular maintenance?
They need the same basics as any small engine: oil changes at the intervals in the manual, a clean air filter, a fresh spark plug, and stabilized fuel if you store it with gasoline in the tank. Run the generator under load for a few minutes every month so the carburetor and battery stay healthy. Keeping a log helps you stay on schedule before storm season.
Can I order a generator just before a storm arrives?
Orders ship fast, but overnight shipping is not available for generators, so order as soon as a storm appears in the forecast. Demand spikes quickly during hurricane season, and buying early leaves time for delivery, fueling, and a test run before the weather arrives.
