Best RV generators

Before we discuss the best RV generators, let’s talk about RVs (recreational vehicles). Recreational Vehicles are motor or automobile homes. These are homes on wheels that can be in the form of towable trailers or one compact vehicle. They are intended for leisure and outdoor activities, like camping. However, an RV can also be used as mobile offices by entrepreneurs who travel to various sites such as construction sites, tourist destinations, etc.

Thus, there are residential RVs with spaces like a kitchen, bedroom, bathroom, and living area.Most RVs are fitted with every imaginable amenity such as satellite receptors, LED TVs, water heaters, air conditioners, heaters, cooking ranges, etc. While the RVs intended for business may have satellite telephones, TVs, fax machines, scanners, copiers, and every conceivable office facility.

Based on the type of recreational vehicle

They are classified as Class A, B, B+, and C vehicles. Most RVs are equipped with extendible canopies. Others have slide-outs that can be extended via hydraulic or electrical systems. The gears of the electric slide-outs are powered by electric motors. All these require power to run. Thus, the essentialrequirement for any modern recreational vehicle with appliances and devices is a powerful RV generator.

A generator supplies the power required to run all the electronics mentioned above. These facilities have an engine fitted with a motor and an alternator that convert mechanical energy into electricity. The mechanical energy to run the engine is obtained from diesel, propane, LPS, gasoline, etc. While some models use solar panels to generate and store electrical energy in batteries.

In the case of engines, the electromagnetic induction produced by a magnetic field generates a push in the conductor, in this case, the circuitry. This push is the electromotive force or voltage that sets off a cascade of electrons in the wire we call electricity.

But Champion 76533 has eliminated this problem with the Champion Cold Start Technology.

You can also easily switch between the propane and gas with a fuel selector located on the top left corner. The best part is that the generator doesn’tneed any customizations. Simply pull it out of the box and start using it straight away.

Power Generation

We tested the generator for a few weeks assuming it can only run light electrical equipment like fans, lights, smartphones, TV, computer, etc. And it worked pretty well without any disturbance. But the manufacturer has made considerableand weighty claims about this generator.

So, we decided to run our refrigerator on the generator along with other electric appliances and devices. And we were surprised to see that the generator was under no pressure. It kept running smoothly even after connecting the refrigerator. We ran the refrigerator and other items for 9 hours and didn’tsee any signs of damage or stoppages.

However, you should avoid using heavy equipment like an iron and room air conditioner because the generator isn’tdesigned for these items.

So, does that mean you can’t run your RV’s air conditioner with this generator?

Well, if you have an air conditioner of 15,000 BTU, you don’tneed to worry at all. But if you have a more oversized air conditioner, we recommend not running it on a generator.

You don’t need to worry about gas availability because you can use the dual fuel feature to switch to propane whenever you want. Champion 76533 can generate 3800-watt on gasoline, and it can continue running for up to 9 hours on a full tank. If you’re using propane, the generator will produce 3420 watts for 10.5 hours on a full tank.

The RV owners don’tneed to worry about wiring and connections because it’s an RV ready generator. Simply connect the generator to your RV using a 120V 30A RV outlet and start enjoying a powerful back-up source. You won’teven have to worry about legal issues because it’s EPA-CARB 50-state compliant.


Champion 76533 is an ideal option for RV enthusiasts who often like to go camping.
