The Generac 18,000-Watt Gas-Powered Portable Generator is a robust option for those needing substantial power output. With an impressive 18,000 watts from its 816cc EFI engine, it is well-suited for emergencies, recreational use, and home backup power.
One of its standout features is the COsense Technology, which offers essential safety by protecting against carbon monoxide. Additionally, TruePower Technology ensures that sensitive electronics and tools can be safely powered, thanks to its low total harmonic distortion (THD) of less than 5%.
This generator also includes a low-oil pressure shutdown feature, which helps prevent engine damage and enhances its longevity. Its large fuel capacity allows for extended runtimes, making it durable for long-term use. However, at 442.8 pounds, it is quite heavy, which could impact its portability despite being labeled as portable. This weight makes it less ideal for frequent transport. The generator runs on gasoline, which is readily available but may not be as convenient as other fuel types like propane.
The Jackery Portable Power Station Explorer 300 is an excellent choice if you're looking for a quiet, portable generator primarily for outdoor use like camping, road trips, or emergency backup. Since it's a battery-powered inverter generator, it produces no fumes and zero noise, which is a big plus compared to traditional gas generators. It offers a steady 300 watts of power through two AC outlets and additional USB ports, allowing you to charge up to six devices at once — perfect for small electronics like phones, cameras, or laptops. Weighing just 7.1 pounds and sized compactly, it’s easy to carry around and fits nicely in a backpack. The Explorer 300 also supports solar charging with an optional Jackery SolarSaga 100 panel, making it a green and renewable power source for longer trips.
One limitation is its modest power output, so it won't run large appliances or power tools. Also, while it has no noise rating listed, its design as a battery unit means it operates silently—ideal for noise-sensitive environments. Its quick recharge time (about 2 hours to 80%) is another convenience factor. If you need a quiet, lightweight generator for charging small devices on the go, this model fits well, but it’s not suited for heavy-duty power needs or extended off-grid use without solar panels.
The Westinghouse Outdoor Power Equipment 14500 Peak Watt Tri-Fuel Home Backup Portable Generator is a versatile and powerful generator, making it suitable for large homes or as a reliable portable power source. It boasts an impressive power output with 14,500 peak watts and 11,500 running watts on 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 flexibility in fuel type – gasoline, propane, and natural gas – allows for extended runtime and convenience, running for up to 19 hours on a 9.5-gallon fuel tank and up to 7 hours on a 20 lb. propane tank. The heavy-duty 550cc 4-Stroke OHV Westinghouse engine ensures durability and longevity, supported by a 3-year limited service, labor, and parts coverage warranty.
For ease of use, it includes an electric start, overload protection, automatic voltage regulation, and a muffler for noise reduction. However, at 230 pounds, it is quite heavy and may not be the easiest to transport. While it is EPA compliant and has a CO sensor for safety, this generator is highly suitable for homeowners needing a reliable backup power source, though its weight could be a potential drawback for some users.
