Looking Beyond the Westinghouse 2550-Watt Inverter Generator? 6 Alternatives Worth a Look

How these alternatives compare

BILT HARD 4500W Dual-Fuel Inverter Generator

The BILT HARD 4500W Dual-Fuel Inverter Generator offers significantly more power than the Westinghouse iGen2550c. It provides 4500W of surge capacity compared to the Westinghouse 2550W peak. You gain dual-fuel versatility, allowing you to use propane or gas, which the gas-only Westinghouse model cannot. However, this extra wattage and fuel flexibility come with a heavier footprint. The BILT HARD weighs 57.7 pounds, making it nearly 18 pounds heavier than the 40-pound Westinghouse unit. It is also larger, measuring 21.4 inches in length versus 19 inches. You should choose this alternative if you need higher wattage for larger loads or want fuel options, and do not mind the added weight for transport.

Westinghouse 2800-Watt Gas Inverter Generator

The Westinghouse iGen2800c stays within the same brand ecosystem but increases your power output. It delivers 2800W of peak wattage, which is 250 watts more than the iGen2550c. This model retains the compact, lightweight design philosophy but adds a bit more mass. It weighs 47.4 pounds, which is 7.4 pounds heavier than the iGen2550c. The dimensions are slightly larger as well, with a length of 19.8 inches compared to 19 inches. Like the original, it features a CO sensor and parallel capability. You should pick this version if you need a modest boost in running power for slightly larger loads while keeping the familiar Westinghouse interface and quiet inverter technology.

Pulsar 4200W Portable Inverter Generator

The Pulsar 4200W Portable Inverter Generator focuses on stable power and parallel capability. It offers a surge wattage of 4200W, which is much higher than the Westinghouse 2550W peak. This makes it suitable for starting larger appliances that the smaller unit might struggle with. It shares the parallel capability feature, allowing you to link units for even more power. However, it is heavier at 49.6 pounds, adding about 9.6 pounds to your carrying load. The physical size is also larger, with a length of 20.5 inches. You should consider this alternative if you prioritize higher wattage and parallel functionality over the absolute lightest weight, while still needing gas power for RV or home backup.

A-iPower 2600W Portable Inverter Generator

The A-iPower SUA2600i 2600W Portable Inverter Generator is designed for maximum portability. It weighs only 38.7 pounds, making it 1.3 pounds lighter than the 40-pound Westinghouse iGen2550c. This slight weight reduction, combined with a narrower width of 10.7 inches, makes it easier to carry. It offers 2600W of surge wattage, which is 50 watts more than the Westinghouse model. It includes a CO sensor for safety, similar to the Westinghouse. However, it lacks the parallel capability found in the Westinghouse iGen2550c. You should choose this unit if your primary goal is carrying the lightest possible generator for camping or tailgating, and you do not need to parallel multiple units for increased output.

AMERISUN 2500W Gas Inverter

The AMERISUN 2500W Gas Inverter Generator matches the Westinghouse iGen2550c in peak wattage, offering 2500W. It weighs 39 pounds, which is 1 pound lighter than the Westinghouse model. Despite the similar weight, its dimensions are different, with a width of 20 inches and a length of 12 inches, creating a different footprint. It includes a CO sensor and parallel capability, matching key safety and expansion features of the Westinghouse. You should consider this alternative if you want a comparable wattage output in a slightly lighter package with a different physical shape. It is a solid option for quiet camping and RV use where weight and safety features are your main priorities.

Westinghouse 5000W Inverter Generator with Remote Start

The Westinghouse iGen5000c 5000W Inverter Generator provides a significant jump in power output. It offers 5000W of surge wattage, nearly double the 2550W peak of the iGen2550c. This makes it suitable for larger RVs or home backup needs. It includes remote start and electric start features, which the iGen2550c lacks. However, this power comes with a substantial weight penalty. The iGen5000c weighs 106 pounds, which is 66 pounds heavier than the iGen2550c. It is also much larger, measuring 24.5 inches in length. You should choose this alternative only if you need high wattage for heavy loads and can handle the stationary or trailer setup, as portability is not a practical concern with this unit.
