Finding the Best Dual Fuel Generator for You
Now that we’ve compared the 10 best dual fuel generators on the market, you have an idea of what’s out there and which models are worth your time and money. However, buying a generator can be confusing, particularly if you’ve never had to use one before. To help make things simpler for you, we’ve created a buying guide that will walk you through all the considerations you need to make before buying anything.
Portable vs. Permanent
You’ll notice that our discussion and best-of list only includes portable dual fuel inverter generators. We didn’t include any permanent models on our list. Why is that? Simply put, portable generators offer more advantages. While a permanent generator might be able to provide you with all the electricity necessary to run an entire home, they can’t be taken with you. They also need to be wired into your home, which adds to the cost and installation time.
With a portable generator, you get enough power to run multiple appliances, but also the portability to take that power generation with you wherever you go. That means you can connect your RV to the generator, or use it at your campsite. You can run your air conditioner and refrigerator at home during a power outage, or you can use the generator at a work site. It’s all about flexibility, convenience, and versatility.
Why Choose a Dual Fuel Inverter Generator?
We’ll start our buying guide with a discussion of why you might want to choose the best dual fuel inverter generator in the first place. When it comes to generators, dual fuel ensures redundancy, but is that important? Why go this route at all? There are plenty of reasons to consider a generator that can run on gasoline or propane.
Perhaps the single most important reason that people shop for the best dual fuel inverter generator is versatility. Simply put, a single-fuel style generator could leave you in the lurch when an emergency strikes. For example, suppose you purchase a conventional gasoline-powered generator. The power goes out, so you fire up your generator. However, the electric company isn’t able to get the lines repaired in time, and you run out of gas.
Now, if you’ve ever weathered a natural disaster before, you know firsthand about long lines at the gas station, fuel shortages, and other challenges. With a dual fuel generator, you don’t have to worry about that. If you run out of gas, just connect the propane tank and keep on running. Where single-fuel style generators can leave you wanting, a dual fuel model will keep you up and running for longer, making them the most versatile option on the market.
Propane vs. Gasoline
Of course, it’s important to know a few things about gasoline and propane and how they work in a generator. In this section, we’ll break down a few things that you’ll need to know.
Efficiency: When it comes to pure efficiency and “bang for your buck”, you’ll find that gasoline delivers. You get more BTU production per gallon of gasoline than you do per pound of propane. That’s seen in the different wattage ratings. If you paid attention to our best-of list, you noticed that gasoline generated more watts than propane.
Environmental Impact: While propane might not have the same BTU rating as gasoline, it does outperform it in other areas. Notably, these are emissions and environmental impact. With propane, you’re able to reduce your carbon footprint (as compared to using gas) and still enjoy access to reliable electricity at home, with your RV, when camping, or in tailgating situations.
Durability/Lifespan: Gasoline seems like an ideal source of fuel, and in many ways, it is. However, it’s not perfect. For instance, did you know that when left in a tank for long periods, gasoline can be corrosive? Did you also know that gasoline has a relatively short shelf-life?
A tank that you purchase now will lose its combustibility over time. Propane, on the other hand, is good forever inside its sealed tank, so you know that it will always be able to power your generator. With a dual fuel model, you get the best of both worlds. You can use gasoline during the short-term, and then save the propane for longer-term needs.
Ultimately, buying a dual fuel portable inverter generator is all about peace of mind. You get multiple fuel options to suit your needs, whatever those might be. You’re not completely reliant on gasoline to generate your electricity, and having two sources of fuel extends your resilience, ensuring that even if a power outage lasts longer than expected and there is a fuel shortage in your area, you and your family won’t be affected.
Now that we’ve explored some of the benefits of a dual fuel generator, it’s time to move on to more practical considerations. For instance, what do you need to look for in a generator? How do you tell if one model is right for you or not?
What Size Generator Do I Need?
Not sure what size generator you need? It can be a tough question to answer, particularly if you’ve never used one before. There’s no one-size-fits-all solution here, either. Thankfully, there are a few ways that you can narrow down your options and begin to home in on what will work best for your specific needs.
The first thing to consider is cost. Dual fuel generators are more expensive than gasoline-powered generators, so you’ll need to consider your budget carefully. You also need to understand that the higher the capacity of the generator, the bigger the price tag will be. So, you can expect to pay more for a generator capable of producing 12,000 watts than one that only produces 4,500 watts. Of course, more wattage generally means more fuel consumption, so you will be spending more on gasoline and propane.
Finally, understand that you do get what you pay for in most instances. While a bargain-basement cost might look appealing, it usually goes along with lower-quality materials and may result in a less than ideal experience. The bottom line? Get as much generator as you can afford, but buy with an eye for quality.
Load refers to the number of items you’ll have connected to the generator at one time. If you only need it to run a few lights at a worksite, then you can spend a lot less than someone who needs a generator to keep their air conditioner and refrigerator running when the power is out at home. As a general rule of thumb, here’s what you can expect to run with various portable generators:
- Up to 3,500 Watts: Most of the generators on our best-of list put out more than this, but we’ll start here as a baseline. With a unit that puts out up to 3,500 watts, you can run a refrigerator, a TV, charge a laptop, run a window unit A/C, and power most lights in a home or RV.
- Up to 7,500 Watts: With a generator capable of producing up to 7,500 watts of power, you can run everything in the section above plus a home security system, a well pump, electric range, or dishwasher.
- Up to 12,000 Watts: If you buy a generator that produces up to 12,000 watts (which is where our list tops out), you can expect to power most things in your home, but not all. For a true whole-home power replacement, you need a home standby generator that produces up to 20,000 watts. With that being said, you could certainly power everything in an RV.
- Surge/Peak/Starter Watts: You’ll notice that in every one of our generator reviews, we listed starting watts. You may also be familiar with these as surge or peak watts. Basically, some systems require a significant amount more power when they first start up, such as your furnace or refrigerator. If you intend to power these items, you’ll need to make sure that your generator puts out enough starter wattage for them.
- Transfer Switches and Sub-Panels: If you intend to use your generator primarily for the home, you may want to consider having a transfer switch and subpanel installed. These allow you to wire right into the home. Otherwise, you will be limited to what you can plug into the generator with extension cords and power strips.
Runtime is an important consideration. It’s basically just a measure of how long your generator’s fuel supply will last at various loads. You’ll notice that in each of our generator reviews, we listed the runtime, but that number was usually accompanied by a note that it was with at half capacity.
Most manufacturers list their maximum runtime at 50% of the unit’s capacity, so make sure you divide the number of hours in half to see how long you’ll get with everything going at once. In some cases, it may be just a few hours, which might not be feasible depending on your situation.
However, you’ll also want to consider how often you’ll really need full capacity. For most mobile use situations, you will rarely use 100% capacity. You might approach that in an RV, though, at least at certain points in the day or if you’re running the air conditioner full blast. Ultimately, know what you’re going to require in terms of a regular load, and how long you need that load to be supported.
All generators will require maintenance to some degree. In most cases, this will be little more than cleaning the outside of the generator and changing the oil. In some situations, you may need to recharge the battery from time to time, particularly if you leave the generator sitting for long periods without using it.
However, despite the limited amount of maintenance needed, some generators are harder to maintain than others are. For instance, you’ll need to change the oil based on runtime hours. Manually tracking those hours can be pretty hard. Look for a unit that offers a digital readout so you can easily track when you need to change the oil and keep your generator in good shape.
Ease of Use
When choosing a portable dual fuel generator, you also need to consider ease of use. Once, the only way to get a generator started was to pull the cord and crank the engine. That was pretty difficult, and those with mobility issues or little upper body strength often found it too hard.
Today’s portable generators get around this problem by using a battery-assisted starting system. All of the units we reviewed have either a keyed starter or a push-button start system. However, batteries can die and leave you in the lurch, so make sure that the generator you ultimately purchase also has a pull cord.
It’s also worth making sure that the generator comes with battery charging cables so that you can keep the battery charged even if you’re not using the generator (all generators should provide a trickle charge to the battery during operation).
Considerations When Buying a Dual Fuel Generator
By this point, you should have a better idea of what size dual fuel generator you’ll need. You should also have a good idea of what to look for in a quality option and how you’ll need to use your generator. That’s not the end of our discussion, though. In this section, we’ll explore some of the additional considerations that you need to make when buying a generator.
All generators require some type of fuel, which means you need to have a place to keep it. With a dual fuel generator, you have two fuel types and you’ll probably want to keep both on hand or you’ll negate the versatility offered. That means you’re going to need to keep both a gas can on hand and a tank of propane.
It’s recommended that you have a dedicated propane tank for your generator, rather than using the one for your grill, as this will ensure that you have a dedicated source of fuel (and that you don’t use all your generator propane grilling burgers and steaks during the summer). Make sure you have someplace protected to store both the gasoline and the propane and ensure that your gas can is large enough for at least one full tank of gas. Because some of these models have larger gas tanks, you may need more than one five-gallon gas can.
While portable generators are designed to work in most temperatures, there are a few things that you’ll need to consider. For instance, very cold temperatures will make the volume of propane in the tank contract, which reduces pressure. With less pressure, there may not be enough propane moving through the line to keep the generator running. So, operating your generator solely on propane during the winter may not be possible depending on where you’re located.
If you’ll be using your generator in a neighborhood or other residential area, be considerate. Some models can be very loud, which affects your neighbors. The good news is that modern portable generators are designed to be quieter during operation – look for a model with a noise emission rating of 65dB or lower if you’ll be using it near your neighbors.
Finally, you need to consider safety. There are several different aspects to think about here, so we’ll run through them separately.
Automatic Low Oil Shutoff: A 4-stroke engine (what most of these generators use) will consume some amount of oil during operation. That’s normal. The problem is that this leads to low oil, reduces lubrication within the engine, and will eventually cause damage, or even destroy it entirely. To get around this issue, manufacturers equip their generators with automatic low oil shutoff switches. However, not all generators have these, so pay attention when comparing your options.
Breakers: Each outlet on your generator should have its own breaker. This helps prevent over-voltage situations, which could result in electric shocks and other safety hazards. A built-in voltage regulator will also help ensure safety for you and protection for devices connected to the generator.
Automatic Shutoff: All of the generators we’ve covered are portable. The problem with that is that they can be knocked over if they are used in a heavily trafficked area. Make sure that the generator you use has an automatic shutoff switch so that if it does tip over, it turns off immediately.
