Best Portable Inverter Generators in 2027

The iGen8200TFc is the closest match to what this keyword asks for. It is an inverter that leads our ranking. On gasoline it rates 6600 W running and 8200 W peak. Running watts are what it can hold for hours. Peak watts cover the brief surge when a motor starts. That is enough for a refrigerator, sump pump and air conditioner at once, per the listing.

Noise and fuel use matter for a camp or a neighborhood outage. The maker lists 60 dBA, and the tank holds 3.9 gal. At 25% load it runs up to 17 hours. The engine speed follows demand, which is how an inverter saves fuel. It also takes gasoline, propane or natural gas, and it starts with a remote. THD is less than 3%, so phones and laptops get clean power.

At 134.5 lb, it is not a light carry. Plan on moving it with help. It has a 50A outlet for an interlock kit or transfer switch, a TT-30R for RVs, and a CO sensor. The warranty is 3 yr.

This is a large backup unit, and it fits the keyword only in part. On gasoline it makes 11500 W running and 14500 W peak. That is the most of any ranked product here, tied with the next model. It is not a compact camping inverter. The listing does not call it an inverter, and it is rated at 74 dBA.

Runtime is where it stands out. The 9.5 gal tank gives up to 19 hours at 25% load, which ties for the longest listed runtime on our page. The 550cc engine uses pressure lubrication. You can run it on gasoline, propane or natural gas, and it has push-button and remote start. The CO sensor and low-oil shutdown are listed.

Size is the cost. At 230 lb, it is heavy, and the 74 dBA level is tied for the loudest on our page. The listing pairs it with the WATS200 transfer switch, sold separately. THD is listed at ≤5%, which is higher than the iGen8200TFc.

The WGen11500DFc shares its engine and output with the tri-fuel model above. The difference is fuel. This one runs on gasoline or propane. It has no natural gas option. If you plan to hook into a gas line, that matters. On gasoline it delivers 11500 W running and 14500 W peak, a range that suits a transfer switch or interlock kit.

Fuel storage and runtime match the tri-fuel version. The tank holds 9.5 gal and the listing gives up to 19 hours at 25% load. Start is push-button or remote. A CO sensor shuts it down when carbon monoxide rises, and low-oil shutdown protects the engine. Copper windings are listed, and the 3 yr warranty comes with lifetime technical support.

Like its sibling, it is a poor fit for camping. It weighs 230 lb and is rated at 74 dBA. The listing also points to the WATS200 automatic transfer switch, sold separately. Pick it for a fixed home spot, not for moving between sites or loading into a truck bed.

Generac rates this unit at 9500 W running and 12500 W peak on gasoline. The listing says the peak figure is 32% above running output, which helps with air conditioners, sump pumps and power tools that surge at start. It runs on gasoline, liquid propane or natural gas, switched with a dial. Start is electric push-button, and a 12V battery is included.

Runtime is shorter than the Westinghouse models above. The 7.5 gal tank gives 14 hours at 25% load, and the listing adds 9.5 hours at 50% load. A fuel gauge and an hour meter are built in. Outlets include two 120V 20A GFCI duplex outlets, an L14-30R and a 14-50R. COsense shuts it down if carbon monoxide rises.

The maker does not publish noise level or THD in our data, so quiet running and clean power for sensitive electronics are unknown. The listing mentions automatic voltage regulation instead. At 219 lb, it is also heavy. Check those points before you buy for camping.

The XP13000HX lists 10500 W running and 13000 W peak on gasoline. Running watts set what it can carry for hours, so size your loads against 10500 W, not the headline number. It runs on gasoline or propane, with a front panel switch for fuel type. Start is electric push-button. That is a simple setup for a house during a storm.

The panel is full. It has four 120V GFCI household outlets, one 120V 30A outlet, one 120/240V 30A twist-lock and a 120/240V 50A outlet that is ready for a transfer switch. The 500cc engine has all copper windings. A CO Alert feature is named in the listing. THD is listed under 5%.

It is the heaviest of the five reviewed here at 240 lb. The data does not list a noise level or warranty. The 8.3 gal tank gives up to 17 hours at 25% load. Treat it as a home backup unit more than a camping generator.
