Best Briggs & Stratton Natural Gas Generators, Reviewed for 2026

The WEN TF-1450X is a premium tri-fuel generator designed for homeowners and contractors who demand flexibility and reliability. Whether you're preparing for emergency blackouts, powering a remote jobsite, or camping off-grid, this 14,500-watt powerhouse adapts to your fuel situation by switching between gasoline, propane, and natural gas with a simple dial. It's the ideal solution for anyone tired of being locked into a single fuel type or concerned about fuel availability during regional emergencies.

Performance is where this generator truly shines. On gasoline, it delivers 14,500 surge watts and 11,500 running watts, enough to simultaneously power essential home systems like refrigerators, furnaces, water heaters, and multiple outlets. The 500cc 4-stroke OHV engine fires up instantly with electric start, and if needed, a manual recoil starter serves as backup. With an 8.2-gallon tank providing up to 12 hours of runtime at half-load, you'll minimize refueling interruptions during extended outages. The digital data meter tracks voltage, frequency, and runtime to help you manage maintenance intervals efficiently.

Build quality reflects WEN's 70-year heritage. The generator features a sturdy frame with wheel and handle kit for easy transport, seven strategically-placed outlets including dual 240V transfer-switch-ready connections (NEMA L14-30R and 14-50R), and inclusion of a 6-foot LPG hose plus NG quick-connect adapter. The WEN Watchdog CO Shutdown Sensor automatically protects your family by detecting dangerous carbon monoxide levels, a critical safety feature for any backup power system. Some users noted minor assembly quirks requiring bracket adjustments, so careful attention to instructions is recommended during setup.

The main drawbacks are relatively minor. The natural gas hose must be purchased separately, adding to your total investment. Additionally, the 50-amp maximum output may limit simultaneous operation of multiple high-draw appliances in larger homes, though most emergency scenarios won't exceed this capacity. These limitations are typical for portable generators in this class and don't significantly diminish the overall value proposition.

The WEN TF-1450X represents an excellent investment for serious backup power needs. Its tri-fuel flexibility, transfer-switch compatibility, electric start convenience, and comprehensive safety features combine to deliver professional-grade performance at a price significantly below comparable standby units.

The Generac GP9500E is a tri-fuel portable generator designed for homeowners, contractors, and outdoor enthusiasts who need reliable backup power with maximum flexibility. This 9,500-running-watt generator adapts to your fuel situation, whether you're using a propane tank during a storm or connecting to a dedicated natural gas line for long-term backup. It's an excellent choice for whole-home emergency backup, job site power, RV use, or outdoor events.

What sets this generator apart is its remarkable fuel flexibility combined with serious power delivery. The 12,500 starting watts handle simultaneous starts of energy-intensive appliances like air conditioners, refrigerators, and sump pumps without breaking a sweat. The built-in Automatic Voltage Regulation keeps output stable, protecting sensitive electronics and motor-driven tools. Runtime is impressive too: up to 9.5 hours at 50 percent load on gasoline, 14 hours at 25 percent load, or virtually unlimited when connected to natural gas.

The build quality reflects Generac's reputation for durability. The steel-tube cradle frame is robust, and the never-flat wheels with folding handle make repositioning manageable despite the 219-pound weight. Push-button electric start with an included 12V battery eliminates frustration, and the digital hour meter helps track maintenance schedules. The control panel offers versatile outlets including dual 120V GFCI outlets, a 120/240V 30A twist-lock, and a 120/240V 50A outlet for comprehensive power needs.

Safety is engineered throughout. COsense technology continuously monitors carbon monoxide levels and automatically shuts down the unit before reaching dangerous thresholds, working silently in the background. Low-oil shutdown protection and covered GFCI outlets add multiple layers of protection. The generator is compatible with Generac HomeLink manual transfer switches, enabling safe whole-home circuit control without backfeeding hazards.

The main drawback is weight and size, which require careful placement planning before emergencies arrive. Maintenance is regular but straightforward. Most users report excellent performance and reliability, though occasional mechanical issues have been reported. Overall, the Generac GP9500E delivers exceptional value for anyone seeking a powerful, flexible backup generator that adapts to their fuel situation and protects their investment through multiple safety features.

The tri-fuel capability is the GP9500E's defining advantage. Gasoline offers the most portable option with the included 7.5-gallon tank delivering extended runtime. Propane provides cleaner burning fuel that can be stored longer without degradation, making it ideal for seasonal backup. Natural gas offers the ultimate solution for permanent installations, providing virtually unlimited runtime by connecting directly to your home's gas line.

Switching between fuels is simple: just turn a dial on the control panel. This means you can start on propane during a storm when gas stations are closed, then switch to natural gas once power is restored and your line is operational. The included natural gas conversion kit and propane hose with regulator make setup straightforward for any fuel option you choose.

COsense technology is your silent guardian. This onboard system continuously monitors carbon monoxide levels during operation and automatically shuts the generator down before CO reaches dangerous thresholds. Unlike detectors that only alert you after hazardous levels are reached, COsense prevents the danger proactively.

Additional safety layers include automatic low-oil shutdown that protects the engine from damage, GFCI-protected outlets that prevent electrical hazards, and covered outlets that protect against accidental contact. The stable voltage output from the Automatic Voltage Regulation system prevents damage to sensitive electronics like computers, medical equipment, and smart home devices.
