10 Best Home Generators 2025 in the United States

The Westinghouse 14500 Peak Watt Tri-Fuel Home Backup Portable Generator is a versatile and powerful option for home backup power. It offers impressive power output with 14,500 peak watts and 11,500 running watts using gasoline, 13,500 peak watts and 10,500 running watts on propane, and 12,000 peak watts and 9,500 running watts on natural gas. This makes it suitable for large homes with significant power needs during outages or as a reliable source of portable power for outdoor activities or projects.

One of the standout features is its tri-fuel capability, allowing it to run on gasoline, propane, or natural gas, providing flexibility based on availability and convenience. The generator can run up to 19 hours on a full 9.5-gallon fuel tank, and around 7 hours on a 20 lb. propane tank, which is quite good for extended power outages. Starting the generator is made easy with a remote electric start, which is very convenient, especially in emergencies. Additionally, it includes features like overload protection, automatic voltage regulation, and a CO sensor for added safety.

However, at 230 pounds, it is quite heavy and may not be easy for everyone to move around, despite being labeled as portable. Backed by a 3-year warranty and supported by a nationwide customer service network, it offers peace of mind. For those needing a robust and flexible backup power solution with the ability to use different fuel types, this Westinghouse generator is a strong option, though its weight may be a consideration for some users.

The Westinghouse 28000 Peak Watt Tri-Fuel Generator is a powerful option for homeowners needing reliable backup power during outages. It offers a very high power output—up to 28,000 peak watts on gasoline and slightly less on propane and natural gas—which makes it suitable for running large homes or multiple appliances simultaneously. The tri-fuel capability is a significant advantage, allowing users to switch between gasoline, propane, and natural gas based on availability and preference. It can operate for up to 13 hours at a quarter load on a full tank of gas, which supports extended power outages. Starting the generator is convenient with a remote electric start, eliminating the need for manual pull-starting.

This generator includes useful features such as automatic low-oil shutdown for engine protection and idle control to reduce noise and fuel consumption when full power is not required. While heavy-duty models like this tend to be louder than smaller home generators, this unit may not be ideal if extremely quiet operation is necessary. Despite its weight of over 550 pounds, it is equipped with large, never-flat wheels and foldable handles to enhance mobility, balancing the power of a stationary unit with some portability. Multiple outlets compatible with transfer switches are included, allowing direct connection to a home's electrical system through a professional electrician, along with safety measures like overload protection and a CO sensor.

The main limitations are its size and weight, which could be challenging for some users despite the mobility features. Additionally, the high power output may exceed the needs of small homes or occasional users. This generator is best suited for larger homes or those seeking a versatile, heavy-duty backup power solution with multiple fuel options and a convenient electric start.

The Generac 7043 22kW Air Cooled Guardian Series Home Standby Generator is a robust option for homeowners looking for reliable power during outages. With its impressive power output of 22,000 watts, it’s designed to protect your entire home, ensuring you won't be left in the dark. One of its standout features is the Mobile Link Wi-Fi connectivity, which allows you to monitor the generator remotely. This can be particularly handy, providing peace of mind if you’re away from home. The generator is powered by natural gas or LP gas, making it versatile for many households.

The 200-amp transfer switch included with the unit ensures seamless operation during an outage, while the advanced True Power Technology offers clean and stable energy, minimizing potential damage to sensitive electronics. Additionally, the 5-year limited warranty adds a layer of confidence in its durability and performance over time.

On the portability front, this generator is quite heavy, weighing 466 pounds, which may limit easy relocation. It also requires professional installation, which can incur additional costs. While it operates quietly compared to many generators, noise levels can still be a concern for some users, especially in quiet neighborhoods. The electric start is a plus for ease of use, but it might be less appealing for those who prefer manual start options. The Generac 7043 is well-equipped for residential use and offers substantial power and advanced features, making it a strong contender for anyone needing a home generator. However, potential buyers should consider its weight, installation requirements, and the ongoing fuel costs associated with its operation before making a decision.
