Both propane and gasoline have advantages and disadvantages when it comes to powering your home. Gasoline is inexpensive, efficient, and relatively easy to source, but it produces toxic fumes and has a comparatively short shelf life. Propane, under the right conditions can be stored for years and produces significantly less CO2, but it is less efficient a fuel source than gasoline and may be difficult to source during an emergency scenario. To help you find the right power source to handle your needs, we’ve rounded up some of the best dual fuel generators on the market today. - **Best Overall**: [DuroMax 15,000 Watt Electric Start Dual Fuel Portable Generator]() - **Most Portable**: [EcoFlow Smart Generator]() - **Best Tri Fuel**: [Sportsman 4,000-Watt Recoil Start Tri Fuel Portable Generator ]() - **Best Solar Generator**: [Jackery Solar Generator 2000 Plus]() ## How I Chose the Best Dual Fuel Generators As a staff writer for Outdoor Life, I’ve spent many hours researching and testing some of the [best solar generators]() and portable power stations. I’m also a long-time camper, and have spent my fair share of time around fuel-powered generators, giving me insight into their advantages and limitations. I’ve researched each of these dual-fuel generators extensively via a combination of first-hand trials, long-term experience with the brand, market research, and real-world consumer reviews. ## The Best Dual Fuel Generators: Reviews & Recommendations ### Best Overall: [DuroMax 15,000 Watt Electric Start Dual Fuel Portable Generator]() If you’re looking for a powerful generator that can handle it all—AC, washer, microwave, freezer—without missing a beat, then you need something big: really big. What sets the DuroMax apart is that in addition to being able to put out 15,000 watts at a time at 120 volts, it can run off of both propane and gasoline, giving you maximum versatility in the event of a power outage. And it manages all that while coming in at a surprisingly small footprint (30 inches x 33 inches x 25 inches). The major downside is that at 83 decibels, this unit is quite loud—imagine standing next to a diesel truck. It may also be overkill for some families that are willing to make do with fewer creature comforts during a power outage and just need something to keep the lights on. ### Most Portable: [EcoFlow Smart Generator]() ![]() *Front of the EcoFlow.* Most dual-fuel generators only supply power while they are (loudly) running. But pairing a dual-fuel generator with a portable power station can be a smart way to maximize the output of your generator, catching and storing all of the power that it’s generating, so that you can turn the thing off, and still get power while enjoying some peace and quiet. The catch is that to store that power, you’re also going to need one of EcoFlows portable power stations, specifically in their [Delta Pro or Delta Max series](). (You’ll also need the EcoFlow Delta Pro to Smart Generator Adapter.) EcoFlow estimates that one full tank in their Smart Generator adds 5.4kWh to your portable power station. Another advantage of the EcoFlow Smart Generator is that, unlike traditional fuel generators, you can control some of it using an app, helping you keep your distance from the noise and fumes. ### Best Tri Fuel: [Sportsman 4,000-Watt Recoil Start Tri Fuel Portable Generator]() One of the biggest issues with generators during power outages is finding a compatible fuel source. Gasoline is typically in the highest demand, but with the increase in natural disasters making dual-fuel generators more common, even propane may end up being scarce. To further diversify the fuel sources you can turn to when a blackout strikes, consider a tri-fuel generator. This option from Sportsman runs off of gasoline, LPG propane, and natural gas, a smart choice for individuals that already have a port at home they can run off of. This unit is also light enough for two people to move comfortably up and down stairs, making it more versatile than heavier options.

Traditional dual-fuel generators run off of propane and gasoline; if you run out, you’ll have to track down refills from the gas station or similar. That’s not always feasible during a power outage, especially a prolonged one where fuel is in high demand. Solar generators run off of the sun. As long as you have access to clear skies, you can keep it charging. Larger power stations, like the Jackery Explorer 2000 Plus, are capable of handling a high solar input, up to 1400 watts. That means that you can add quite a few panels to your array to really maximize the potential of the sun to power your home. And the larger size of the power station in this case means that you can have power pre-stored in your setup, ready to go as soon as the lights go off. Of course the catch is that this doesn’t work very well if you live in a gloomier part of the country. But if you live in the sunbelt or another cloud-free zone, a solar generator is a great way to access the free power of the sun whenever you need it. ## Things to Consider Before Choosing the Best Dual Fuel Generators ### Gas versus Propane versus Natural Gas (versus Solar) There are pros and cons to every fuel source. Gasoline is readily available and efficient, but you can’t store it for longer than three to six months. Propane is somewhat more difficult to find, but it stores for a lot longer (decades). While it produces less electricity typically than gas, it also produces less CO2.

The catch is this typically involves quite a bit of setup and expense, including professional help. Solar power is easy to set up and very satisfying to capture. The catch is that it works significantly less well if the sky is overcast (and not at all if it is night) and most arrays can’t handle enough of a load to consistently run power-hungry appliances like air conditioners. ### Fuel Availability Depending on where you are, it may be easier or more difficult to secure propane or gas. Gas you’d get, unsurprisingly, at a gas station, which can often have long lines with people trying to both fuel their cars and their cans for their home generators. Propane, on the other hand, can be more difficult to find, but there is typically less demand. You can also look for propane swap stations to refuel existing cans. ### Weight Dual fuel generators are typically not good choices for outdoor recreational use, as they are much heavier and more cumbersome to move than single-fuel or solar generators. Before choosing a unit, consider how much you are planning to move it (if at all) and whether its weight aligns with your needs. ## FAQs ## Final Thoughts on the Best Dual Fuel Generators If concerns about an unexpected blackout have you losing sleep, then it’s time to invest in a generator that gives you options for how you keep the lights on in your home. A dual-fuel generator, like the ones covered here, allows you to store power long-term and power up through gasoline, propane, natural, and energy from the sun. - **Best Overall**: [DuroMax 15,000 Watt Electric Start Dual Fuel Portable Generator]() - **Most Portable**: [EcoFlow Smart Generator]() - **Best Tri Fuel**: [Sportsman 4,000-Watt Recoil Start Tri Fuel Portable Generator ]() - **Best Solar Generator**: [Jackery Solar Generator 2000 Plus]() ## Author Laura Lancaster is an Outdoor Life's gear writer where she focuses on in-depth testing of backpacking and camping gear, with a particular interest in lightweight and ultralight gear.
