Top 5 Best 50 Amp Generators
7 Best 50 Amp Generators Review
1. Westinghouse 12500 Watt Dual Fuel Home Backup Portable Generator
The Westinghouse 12500 Watt is a powerhouse designed for serious home backup or heavy-duty use. It’s perfect for homeowners seeking to run essential and luxury items during extended outages, from the well pump to the central AC. Its main selling point is the substantial 12,500 peak watts on gas, delivered through a transfer switch-ready 14-50R 50A outlet. This model provides the high wattage needed to power most large homes entirely, making it one of the leading Best 50 Amp Generators available.
In terms of performance, the heavy-duty 457cc OHV engine, paired with a long-lasting cast iron sleeve, ensures exceptional durability. The included remote start key fob is a game-changer for convenience, allowing you to fire it up from inside your home. However, while the 12-hour run time at half load is impressive, the unit’s 210-pound weight, even with the wheel kit, makes physical maneuvering somewhat challenging. Furthermore, the VFT digital display provides real-time voltage and frequency data, which is crucial for monitoring sensitive electronics.
Overall, this is a top-tier choice for those who cannot compromise on power or run time. It’s ideally suited for large homes requiring reliable, whole-house backup. While its size demands a dedicated storage space, the combination of dual-fuel flexibility and robust 50-amp power makes it an outstanding investment for emergency preparedness.

How to Choose Best 50 Amp Generators
Investing in a high-wattage generator, particularly one with a 50-amp outlet, is vital for safeguarding your home or project. Best 50 Amp Generators are non-negotiable for running multiple large loads simultaneously, like a central air conditioner, well pump, or major power tools on a job site. The key is to match the generator’s capacity to your total essential and desired loads to avoid overloading. This section details the five most critical features to evaluate before making your purchase.
Power Output (Running vs. Starting Watts)
Power output determines what you can run. You must calculate the surge watts (highest temporary power) and running watts (continuous power) of all appliances you intend to use. Always select a generator whose running wattage exceeds the total running wattage of your devices. For 50-amp applications, look for units starting at 9,000 running watts or higher to ensure there’s enough power for critical items and motor startup.
Fuel Type and Flexibility
Dual-fuel capability (Gasoline and Propane) is strongly recommended as it offers essential flexibility. Gasoline provides maximum peak power, while propane can be stored longer, is often cheaper, and may be easier to acquire during widespread outages. Assess the propane wattage drop—many dual-fuel units lose 10% to 15% of power on propane, which is an important consideration for peak load management.
The 50-Amp Outlet (NEMA 14-50R/TT-50A)
The 50-amp outlet is the primary reason for choosing these generators. The NEMA 14-50R is the standard for connecting to a home transfer switch, while the TT-50A is typically used for RV power. Ensure the generator you choose has the correct receptacle type for your intended use (home backup or large RV). This connection is what allows for the full 50A current draw.
Safety and Monitoring Features
Modern safety features like CO (Carbon Monoxide) sensors are now standard on many top models, automatically shutting off the generator if toxic fumes build up. Low-oil shutoff prevents engine damage, and an Automatic Voltage Regulator (AVR) is crucial for protecting sensitive electronics like computers and smart devices from voltage spikes.
Portability and Build Quality
These are heavy units, so a robust wheel kit with large, all-terrain tires and solid, drop-down handles is essential for portability. Look for heavy-duty steel frames and cast-iron sleeves in the engine, as these indicate a commercial-grade build designed to withstand harsh weather and repeated transport or heavy use over many years.
Maintaining Your Best 50 Amp Generators
To ensure your investment delivers reliable power for years, regular maintenance is non-negotiable. One common mistake buyers make is neglecting to perform a monthly test run. You should run your generator for 15–20 minutes every month under a half load to keep the carburetor and fuel system lubricated. Another crucial insight is fuel management: never store gasoline in the tank for more than a month without a fuel stabilizer, as stale fuel is the leading cause of non-starting issues. Propane, on the other hand, is a clean-burning fuel with an indefinite shelf life, making the dual-fuel models particularly advantageous for long-term emergency storage.
How to Use Best 50 Amp Generators
To safely and effectively utilize your 50A generator, follow these practical steps:
- Step 1: Setup/Prep: Place the generator on a flat, level surface outdoors and at least 15 feet away from your home’s windows or doors. Check the oil level and fill the tank with stabilized gasoline or connect the propane hose firmly to the regulator and tank.
- Step 2: Core Usage & Best Practices: Use the electric or remote start to power the unit. If connecting to a home, use a properly rated 50A power cord to link the NEMA 14-50R outlet to your transfer switch inlet box. Ensure the main breaker is OFF before activating the transfer switch.
- Step 3: Optimization/Safety/Maintenance: Start with your highest-wattage items (e.g., A/C) first, then layer on smaller loads. Never exceed the generator’s running wattage. For safety, always turn the engine off and allow it to cool completely before refueling.
- Step 4: Troubleshooting & Pro Tips: If the generator stalls, check the fuel selector, reset the circuit breakers on the unit, and ensure the low-oil sensor hasn’t triggered a shutdown. Keep an extra spark plug and a full bottle of oil on hand for basic field repairs.
Frequently Asked Questions
What is the benefit of a 50 Amp Generator over a 30 Amp Generator?
A 50-amp generator provides significantly more power—typically 12,000 watts to 14,000 watts—which is required to run multiple heavy loads like central air conditioning, an electric water heater, and several household circuits simultaneously. A 30-amp unit (around 7,500W) is generally sufficient only for essential circuits and small RVs.
Do Best 50 Amp Generators use a lot more fuel?
Yes, due to their larger engines (often 450cc or more) and higher power output, these generators will consume more fuel than smaller models, especially under heavy load. However, their efficiency, measured in run time per gallon at half load, is often competitive within their high-wattage class.
Can I use a 50 Amp Generator for my RV?
Absolutely. Many large RVs, particularly fifth-wheels and Class A motorhomes, are wired for 50-amp service to run two air conditioners and multiple high-draw appliances. You should ensure the generator has the appropriate TT-50A RV-ready outlet for a direct connection.
Is a dual-fuel Best 50 Amp Generators model worth the extra cost?
Yes, the dual-fuel capability is highly recommended. It offers fuel flexibility, which is critical during emergencies when gasoline might be scarce but propane is still available. Propane also burns cleaner and stores indefinitely, reducing long-term maintenance costs and carburetor issues.
How often should I change the oil in my 50-amp generator?
The first oil change is typically recommended after the first 20–30 hours of use (the break-in period). After that, manufacturers usually recommend changing the oil every 50 to 100 hours of continuous operation to maintain engine health and efficiency.
Final Thoughts
Choosing among the Best 50 Amp Generators is primarily about balancing raw power with necessary features like dual-fuel capability and essential safety systems. The right unit will provide reliable, uninterrupted power when you need it most, ensuring your home or project keeps running. By focusing on your total wattage requirements, the type of 50A outlet needed, and a robust build, you can confidently invest in a generator that will serve as a resilient backbone for your power needs.
