img style=”border: none !important; margin: 0px !important;” src=”” alt=”” width=”1″ height=”1″ border=”0″ />This Champion generator is easy to use and doesn’t weigh a ton for what it provides. It operates great on both propane and gas and isn’t loud at all. We had to use it a few times when the RV park electricity went out and it didn’t really bother anyone because of how quiet it is.

The Champion 3400-watt dual fuel generator is an electric start generator, which is another reason we love it. I’ve never been able to get anything to start with a pull string, but if you do like it that way, you can use the pull string on it.

When you run this generator on propane, you’ll get 14.5 hours of run time and on gas, you get 7.5 hours. Both of these run times give you plenty of time to use the generator without hassling with fuel.

If you’re worried you’re going to sink your money into a generator that doesn’t work—never fear. There is a 3-year limited warranty so you can rest easy and enjoy the power and you get lifetime technical support from experts.

This is a great generator if you’re looking for something that is user-friendly for beginners, but it’s great for people that are veteran RVers as well. You’ll love that it has a USB port and plenty of places to plug in.

Why Are Dual Fuel Generators a Good Idea?

I don’t know if you’re anything like me, but sometimes I tend to be forgetful. If you only have one type of fuel, it’s easy to use it up and then you’re out of luck until you go get some more. But when you have a dual fuel portable generator, you’ll be able to use up one type of fuel and then start on the other.

Get More Bang for Your Buck

When you’re out camping, you don’t want to have to mess with your generator any more than you have to. When you use propane, your generator can stay on longer than if you only have a generator that uses gas.

Using a dual fuel portable generator is easy even though it might seem intimidating because you added another type of fuel.

The good news is that most of these models are more modern than traditional generators so you’ll see a lot of push-starting or even remote start so you can choose to use the push-start option or crank it the old-fashioned way.

Depending on the generator you buy, you can easily switch from gas or propane with a switch or knob so it’s easy to see which type of fuel you’re using.

Helpful in a Pinch

When you’re in a pinch, you might only have one type of fuel available. If your generator wasn’t dual fuel then you’d have to rush to find the right fuel if you don’t have it. Having a dual fuel generator also makes it more likely that someone close by would have the fuel in case you need to borrow or buy it from a neighbor.

Emergencies rarely come at convenient times but if you’re ready for it, you won’t have as much frustration.

What Size Generator Do I Need?

When we were trying to find the right generator, this was probably the most frustrating part of the process. I didn’t want to get a generator that wasn’t big enough and have to get another one, but I also didn’t want to get one that was too big and spend money I didn’t need to spend.

The best way to make sure you get the right size generator for you is to add up all of the watts your appliances use. If you won’t use them all at the same time, you might not need as many watts, but keep in mind that we usually end up using more than we thought we would.

Here is a good way to find out to help you figure out how big of a generator you need for your RV.

Now let’s get back into the list of generators so you can choose the right one for you.

2. Durostar DS10000EH Dual Fuel Portable Generator-10000 Watt Electric Start

If you really want a beefy dual fuel generator then the Durostar DS10000EH dual fuel portable generator will give you as much power as you want. Well, 10,000 starting watts and 8,000 running watts.

Keep in mind that you might not need this much power for your RV. This bad boy can run a home refrigerator, a/c, and lights at a house. If you have a big rig, you still might want to check it out and it can give you some peace of mind.

You can choose to operate the RV at 120 volt and 240 volt at the same time or you can operate on 120 volt only with full power.

The power panel gives you a lot of selection opportunities. It has two 120 volt household GFCI outlets, one 120 volt 30A twist-lock outlet, one 240 volt 50A outlet, and one 240 volt 30A outlet. You’ll also see a voltmeter and 12 volt DC charging so you can charge external batteries.

With the electric start, you can easily get your generator going with the turn of a key. Once it gets going, it can go for around 11 hours because of its 4-gallon tank.

Also included with the generator is a bottle of oil, a wheel and handle kit, and a 47-inch LPG connection hose. You also get a 2-year limited warranty in case something goes wrong with the generator in that time period.

A cool feature of this generator is that it will lower the PRMs of the generator when it doesn’t need to go at full tilt. This saves energy and lowers the sound it puts out. Another one you should know about is the low oil shut-off. If your oil gets low, it will shut off and won’t go again until you give it some oil.

There are two home plugs on the generator so you can plug in normal appliances or charge your phone.

You can also use the parallel feature and bridge two of these units together if you need to double the wattage. Keep in mind that it doesn’t come with the kit and you have to buy it separately.


  • Lightweight
  • Low price
  • Quiet
  • Fuel-efficient


  • Only for small loads
