10 Best Generator Inverters 2025 in the United States

The Westinghouse 11000 Peak Watt Tri-Fuel Portable Inverter Generator offers a powerful solution for those needing reliable backup power at home or on the go. Its tri-fuel capability means you can run it on gasoline, propane, or natural gas, providing flexibility depending on what fuel you have available. It delivers a strong 9000 running watts on gas (up to 11000 peak watts), making it suitable for whole-home backup and heavy-duty tasks. The inverter technology helps the engine adjust speed based on demand, which reduces fuel consumption and noise, making it quieter than conventional generators. It runs up to 19 hours on a full 7.9-gallon tank, so you won’t have to refuel often during outages or camping trips.

Safety is well covered, with a built-in carbon monoxide sensor and automatic low oil shutdown to prevent damage or hazards. The generator also features a digital LED display to monitor fuel level, power output, and runtime, plus a remote start for convenience. However, at 191 pounds, this unit is quite heavy and may not be the best choice if you need a generator for frequent transport or quick moves. Also, while the noise level is lower than traditional models, 76 dBA is still noticeable in very quiet environments.

The variety of outlets, including a 50A outlet ready for transfer switches, makes this generator versatile for home or RV use. This unit is a dependable, flexible, and feature-rich inverter generator with strong power output, though it may feel bulky if portability is a top priority.

The DuroMax XP16000iH is a strong choice if you need a powerful generator for whole-home backup, job sites, or RV use. With 16,000 peak watts and 13,000 running watts, it delivers plenty of power to keep essential appliances and tools running smoothly. Its dual fuel ability to run on gasoline or propane adds flexibility, especially during emergencies when fuel options might be limited. The inverter technology is a big plus, producing clean and stable electricity that's safe for sensitive devices like laptops and TVs.

Portability is somewhat limited due to its heavy weight (368 pounds), so while it’s technically portable, moving it around might require effort or assistance. Features like remote electric start and a digital control screen make operation easier and more convenient. The generator also includes safety measures such as low oil shutoff and a CO sensor, which protect both the user and the machine. Runtime depends on fuel and usage, but the large 10.5-gallon tank supports extended operation.

Generators this powerful generally produce noticeable sound, so it might not be ideal for very quiet settings. This model suits users needing reliable, high-capacity power with modern features, but it may be overkill for casual or light use due to its size and weight.

The Honda 664240 EU2200i is a versatile and portable inverter generator that offers a power output of 2200 watts, making it suitable for a variety of uses such as home backup, camping, and job sites. One of its standout features is the noise level, operating at a quiet 48 to 57 dBA, which is quieter than a normal conversation, ideal for environments where noise sensitivity is important. The generator runs on gasoline, providing a good balance between availability and energy efficiency.

With a runtime of up to 9.6 hours on a single tank, it can handle overnight or long-duration tasks efficiently. Weighing 46.5 pounds, it's relatively lightweight and portable, though some may find it a bit heavy for extended carrying. The Eco-Throttle System enhances fuel efficiency and the inverter technology ensures clean and stable power, safe for sensitive electronics. Additionally, the option to parallel it with another EU2200i unit to double the power output is a valuable feature for those needing more power occasionally.

A minor drawback is the small fuel tank capacity of 0.95 gallons, which might require more frequent refueling during extended use. This generator is an excellent choice for users needing reliable, quiet, and portable power with high efficiency and clean energy output.
