10 Best Generators 2025 in the United States

The Westinghouse 12500 Peak Watt Portable Generator is a solid choice for homeowners needing reliable backup power during outages. It delivers 9500 running watts and a peak of 12500 watts, enough to support essential household appliances and some heavier equipment. Powered by gasoline, it runs up to 12 hours on a full 6.6-gallon tank, which is convenient for extended use without frequent refueling. Starting the generator is easy with a remote electric start plus a recoil backup, providing options depending on the situation.

This model includes a good variety of outlets: standard household plugs, a 30A transfer switch outlet, a 50A RV outlet, and USB ports, making it versatile for many devices and transfer switch setups. The built-in fuel gauge and hour meter help you monitor usage clearly. Noise-wise, it runs at about 74 dB, which is noticeable but typical for this power range—so it’s not the quietest, but acceptable for outdoor use.

Weighing 220 pounds, it’s fairly heavy and not easily handheld portable, but the design is intended more for stationary backup rather than frequent moving. Safety features like automatic low oil shutdown and rubber covers on outlets add peace of mind. The 3-year warranty and wide customer service network support reliability. The size and weight limit easy transport, and the noise level might be a concern if you need something quieter for close-to-home use. Also, being gas-powered requires storage and handling of fuel, which some might find inconvenient compared to propane or inverter generators. For those seeking a powerful, dependable generator for home backup with solid run time and multiple outlet options, this Westinghouse model is a strong fit.

The Generac GP9500E TF is a powerful portable generator offering 9,500 running watts and 12,500 starting watts, making it suitable for home backup, job sites, or recreational vehicles that need a strong power source. It stands out with its tri-fuel capability, allowing you to use gasoline, propane, or natural gas with an easy fuel selector switch, giving flexibility depending on fuel availability. This is great for longer use or emergency situations. The electric start feature makes it simple to operate without manual effort, a helpful convenience in urgent power outages.

The generator runs up to about 9.5 hours at half load on gasoline, supported by a sizable 7.5-gallon tank, which means fewer refills during extended use. It includes protective covered outlets and CO sensor technology for safer operation, especially indoors or near living spaces. Portability is decent though it weighs 219 pounds, but it has sturdy wheels and a strong steel frame that makes moving it easier on job sites or campsites. It provides three 120V outlets, which covers typical household and tool needs but may be limited if you want to power many devices at once.

One downside is the weight, which might be challenging for some users to lift or transport without assistance. Also, while it is durable and suited for rugged conditions, the size may be bulky for very compact storage or small vehicle trunks. This generator represents a solid choice if you need a reliable, versatile power source with multiple fuel options and easy starting, especially for home backup or outdoor work. Just be prepared for its weight and consider if the number of outlets fits your setup.

The Generac Guardian 26kW Home Standby Generator is a strong choice for homeowners who want reliable backup power during storms or outages. It delivers a solid 26,000 watts, which is enough to power an entire house, including essential appliances and systems. The generator works with natural gas or liquid propane, giving you fuel flexibility. Its 200 Amp transfer switch ensures smooth and automatic power transfer, so you don’t have to worry about manual setup when the power goes out.

One standout feature is its Wi-Fi connectivity, allowing you to monitor the generator’s status and maintenance needs remotely, which adds convenience and peace of mind. The unit is designed to be quiet for its size, with a fully enclosed casing and low oil shutdown to protect the engine. Built with a durable aluminum frame and crafted in the USA, it promises long-lasting performance backed by a 5-year warranty.

This generator is quite heavy at over 500 pounds and not portable, meaning it’s meant to be permanently installed by a professional electrician. This limits flexibility if you need something for occasional or mobile use. With 10 power outlets and stable voltage output, it’s well-equipped to handle multiple devices safely. If you want a dependable, automatic whole-house generator that you can keep an eye on remotely and don’t need portability, this model fits the bill well. It is better suited for those looking for a fixed installation rather than a generator to move around.
