Generators have become an essential part of our lives, especially in times of unexpected power outages or when you’re off the grid. And let’s be honest, having a dual fuel generator that runs on both gasoline and propane gives you unmatched flexibility and convenience. Whether you’re prepping for emergencies, heading out on a camping trip, or need backup power for your home, a dual fuel generator offers a perfect solution.
Here, we’ll dive into the 10 best dual fuel generators of 2025, covering their features, runtime, capacity, and why they’re worth considering. Buckle up as we explore these power-packed options!
What is a Dual Fuel Generator, and Why Do You Need One?
Before we jump to the list, let’s cover the basics. A dual fuel generator operates on two types of fuel—gasoline and propane. This versatility means you can switch between fuels based on availability, cost, or your specific needs. Gasoline is widely accessible, while propane burns cleaner and stores longer.
The dual fuel capability makes these generators ideal for a variety of situations, whether you’re dealing with prolonged blackouts, powering a job site, or enjoying an RV adventure.

Key Features to Look for in a Dual Fuel Generator
1. Power Output
The wattage determines how much equipment you can power simultaneously. If you’re running heavy-duty appliances, aim for generators with 10,000 watts or more.
2. Runtime
How long the generator runs on a full tank matters, especially during extended outages. Check both gasoline and propane runtimes to suit your needs.
3. Portability
Let’s face it, no one wants to lug around a heavy machine. Look for models with wheels and handles for easy transport.
4. Safety Features
Features like low-oil shutoff, overload protection, and automatic voltage regulation can save you from accidents and extend the life of your generator.
5. Noise Levels
Generators can be noisy, and the last thing you want is a headache from constant buzzing. Go for models with a decibel rating under 75 for quieter operation.
Why Dual Fuel Generators Are Game-Changers
Imagine you’re in the middle of a power outage. Gasoline is running low, but you’ve got a propane tank in the backyard. With a dual fuel generator, switching is seamless, giving you peace of mind and uninterrupted power.
Plus, propane stores longer without degrading, making it a better option for emergencies. Dual fuel generators give you the best of both worlds—more options and less stress.
