Key Considerations When Buying a 50 Amp Generator

1. Fuel Type

The ability to use multiple fuel types (gasoline, propane, or natural gas) enhances versatility. Dual fuel models offer cost-effective operation, while tri-fuel options provide added security during fuel shortages.

2. Output Power

Determine how much wattage you need. If powering an entire house or job site, models like the Westinghouse 28000W offer unmatched performance. For smaller applications, 9,000–11,000W units may suffice.

3. Portability

Despite their high power, many of these units are wheel-equipped and designed for easy transport. If mobility is a priority, look for manageable weights and ergonomic handles.

4. Start Mechanism

Electric and remote start features are more convenient than manual recoil, especially in adverse weather.

5. Runtime and Fuel Capacity

Longer runtimes reduce the need for constant refueling. Look for models that can run at least 10–17 hours on a single tank, especially for overnight power needs.

6. Safety Features

Modern generators include CO detection sensors, automatic shutoff, overload protection, and LED diagnostics. These features are essential for both personal and equipment safety.
