Best camper generator

Last Updated: 30.09.22


What are the best camper generators in 2022?


If you’re looking for a good camper generator but don’t have the time to read through this whole material, then we’ll tell you first-off that our top pick is the Champion 75537i. Somewhat unusual for an item its size, this small, portable camper generator has an inverter, which will assure a steady supply of AC current with no power surges, so that your sensitive electronics can be safely plugged in. Besides the regular 120 V, 30 A outlet that’s specifically intended for RV use, the Champion can also connect to your household electrical appliances by two 120 V, 20 A outlets. To top it off, an included adapter can deliver 12 V of DC current for recharging batteries or jump-start a car.  If you’re not interested in an inverter, then the Champion 76533 offers its own set of very attractive features.

A short buying guide


Before setting out to find the best trailer generator for sale, there are a couple of things we should be aware of in order to ensure the best purchase.


How many watts do I need?


The best generator for RV won’t necessarily deliver the highest amount of power (after all, it’s not a sports car) but it should provide enough electricity to cover the electrical appliances you commonly use.

Both the generator’s output and the energy your appliances require to run is conveniently measured in Watts, so it’s very easy to make a calculation of the wattage you need by adding up all the consumers.

The most basic RV setup will feature an 80 liter fridge, which usually runs at 55 W; two 30-watt lights; one radio or TV for 200 W; a 1300 W air conditioner; and a phone charger of around 5 W. This adds up to 1600 W, which might double for RVers who like their luxury away from home.

It’s good to have some leeway, but going a lot higher than what’s required will leave the generator burning expensive gasoline for no reason. Some newer models do have economic modes, which lets them operate at reduced capacity, and should definitely be something to look into if you don’t expect a consistent energy usage.   


Features to look for


An electric start means that you won’t have to spend minutes of your time cranking a cable to get the engine running, and most units that feature this also have a traditional back-up. There’s little reason not to opt for it, especially as it doesn’t add a lot to the price.

In the US, a typical generator will run on gasoline, but there are other options of fuel available, such as propane or natural gas. Besides being slightly cheaper, propane also has a higher shelf-life than gasoline, so it can be stored for emergencies.

A low-oil shut-off means that the generator won’t be running on dry, which can seriously cut its lifespan, not to mention smoke the entire campsite.     


Convenience features  


The best camper generator is a silent camper generator! Even if the machine is supposed to be kept at a minimum of 23 feet from you while running, that doesn’t mean it can’t prove bothersome in a trailer park or when trying to enjoy nature.

If you don’t like dragging heavy loads around, then size and weight will become an issue. All good units are fitted with roll cages to grab them by and wheels to roll, but you won’t always be able to find a smooth surface for the latter.



Our top picks



Champion 75537i


This one gets top scores in camper generator reviews because of its remarkable array of features, which seem to include everything currently available on the market.

Somewhat unusual of a unit its size, it has an electrical inverter, which allows it to deliver steady current, with less than 3% THD (total harmonic distortion). This basically means it won’t fry any electronics attached to it through surges in current.

To take full advantage of this fact, 2 of its outlets deliver 120 V 20 A regular household current, with a third being used for the 30 A common with campers and an extra 12 V DC charger plug to top it off.

The 2800 W running power should cover most uses, and on a slow day, this can be reduced to provide more fuel economy and allow for a longer functioning time. You might sometimes be confused on whether it is running or not, as it only puts out 58 dBA of noise at 23 feet.

Champion 76533


Main advantage

The first aspect you should know about this device is the fact that it’s a dual fuel model that runs on both gas or propane straight out of the box. With a propane hose included in the package, you’ll be able to use it right after purchasing it without any trouble.

Moreover, the model also includes a patented fuel selector switch that allows the user to quickly and safely switch from one fuel source to the other. When it runs on gasoline, the generator can produce 4750 starting watts and then 3800 running watts, while these numbers are 4275 starting watts and 3420 running watts when running on propane.


Main disadvantage

Given its capacity and the fact that you can use it to power quite a large number of appliances in case you need to, the unit is considered by some users to be rather heavy and loud. In terms of the sound level it produces, you might want to know that it operates at 68 dBA from 23 ft.

If you think this number is too high for your needs, you might need to look at other alternatives as well. However, do keep in mind that this is similar to having background music or conversations in a restaurant, so it’s not really that much.

Top 3 features explained


Running time

Many features make this a very good addition to your RV, for example, but one of them is the running time. Given the up to 9 hours run time on a full tank of gas and the average of 10.5 hours when running on a 20 lb. propane tank, you can rest assured that you don’t need to face any emergency situation in terms of your appliances anytime soon.

Besides being a convenient solution, this is also a cost-effective one, especially during those times when you are dealing with a longer power outage in your area. By using this device, you’ll be able to power the essential items around the house for longer periods while having enough time to look for solutions.



Touch Start

The generator is powered by a 224cc Champion engine you can rely on and that features a Touch Start, a push-button electric start that definitely comes in handy. Given that the unit needs to be ready to run at any given point, the device also includes an internal battery that charges the battery as the generator is in use.



As you can only imagine, this device does need to run in safe conditions and the manufacturer is more than aware of this aspect, given that it included in the design many features that make this unit a safe one, besides the fact that it’s portable and convenient.

The generator includes the Volt Guard, which is a built-in surge protector that keeps your appliances safe from spikes in voltage that go above a safe threshold.

Furthermore, since varying temperatures can also be an issue, the Cold Start technology comes in handy as it optimizes the generator to easily start in cold weather. This way there is little left to worry about.

Sportsman GEN4000


This Sportsman GEN4000 has almost all the features you’d expect from a top of the range model, but it comes at a significantly lower price. It produces 3500 running Watts with a 212 cc gas engine that can be kept running at 50% capacity for up to 10 hours.

While we do recommend you always keep an eye on the oil gage, this item will prove forgiving to any mishaps since it has a low-oil shut-off feature, which turns it off whenever the level drops under certain limits.

It has four household outlets to share the load, a dedicated 120 V 30 A outlet for an RV and a 12 V battery charger. The front panel also contains an electrical start-up button and a voltmeter.

While relatively light and easy to pick up by two side-handles, the GEN4000 doesn’t come with its own wheels, and you might want to add a couple of dozen dollars to the price for purchasing some.
