Best Dual Fuel Generators – Comprehensive Buyers Guide

Dual-fuel generators, also called hybrids, can run on two types of fuel, usually gasoline and propane or sometimes natural gas. Having both options offers more flexibility in operational costs, run time and storage.

Table of Best Dual Fuel Generators

Gasoline is the standard fuel type for generators but there are certain disadvantages – difficult to store, subject to price fluctuations – that propane does not have. Propane is often cheaper which lowers your running costs, it can be stored indefinitely and even reduces the noise level of the machine.

For some, having a longer total run time is already enough reason to get a dual fuel generator. Depending on the model, you can seamlessly switch between fuel supplies which drastically extends how long you can keep the generator running before you need to shut it down for refueling.

Here are ten of the best hybrid generators, ranging from lower output inverters to more heavy duty models. Which one meets your power needs?

1. Champion 7500-Watt Dual Fuel

Champion Power Equipment 100165 9375/7500-Watt Dual Fuel Portable Generator with Electric Start

Check Current Price

Champion generators are popular in general but this mid-size dual fuel model in particular has earned lots of positive reviews. It has 7500 watts continuous on gasoline and 6750 watts on propane.

This is a user-friendly model with an electrical starter and also cold start technology so that it does not fail in colder climates. The Intelligauge on the control panel also keeps it easy to monitor as it shows the run time, voltage, output and even maintenance reminders.

Run time is decent but it is less than many other models available on the market. On the other hand, this is also one of the larger engines featured so keep that in mind when considering what you can hook up to it during that shorter time period.

Pros and Cons

PROs
  • Intelligauge
  • Easy to start
CONs
  • Loud
  • Average run time

9. DuroMax XP2000EH

DuroMax XP2000EH Dual Fuel Inverter Generator, Blue

Check Current Price

Not in need of a lot of power or is portability more important to you? Then consider the DuroMax XP12000EH inverter generator which is great for camping.

This lightweight machine only weighs 47 pounds so you can easily carry it with you anywhere or even take 2 so that you can make use of its parallel capabilities for twice the power output. This is a small capacity generator so it is more suited for charging sensitive electronics like laptops, mobile phones and DSLR cameras or drones.

Th run time is below average on gasoline which is understandable for the small tank but it does offer an astounding 21 hours of run time when hooked up to a 20 lbs propane tank. The engine runs quiet enough for a campsite at 61 decibels which is about the same level of noise as a normal conversation between 2 people.

Pros and Cons

PROs
  • Lightweight
  • Very long run time on propane
  • Quiet
CONs
  • Low capacity
  • Small gasoline fuel tank

10. DuroStar Hybrid Dual Fuel DS10000EH

Durostar DS10000EH Dual Fuel Portable Generator-10000 Watt Electric Start-Home Back Up & RV Ready,...

Check Current Price

This design by DuroStar was meant for heavy duty use but it could also double as a whole house backup generator. It delivers great power, on either fuel type, and it is also fuel-efficient enough for a long run time of over 10 hours on gasoline and over 8 hours on propane.

This model has an MX2 switch that lets you double up the 120 volt power outlet for bigger loads and lets you run at both 120 volt and 240 volt at the same time. This is great for high power requirements or when you need to connect lots of devices.

The downside is that it is quite heavy, even with the tires and pulling handle so this is not the most portable option.

  • High capacity
  • Fuel-efficient
CONs
