Buying Guide

After reviewing the best inverter generator models, you are now wondering about the criteria to compare and find the product that best suits your needs. That’s why you should consider the following notes. Let’s check them out!

Power Output

With this criterion, you need to consider the ratings of the devices. Besides, don’t forget to take care of concurrently running devices.

You certainly wouldn’t be able to run all the devices simultaneously because this action can lead to overload and circuit breakers.

You should consider the types of devices that are required to run at the same time to be able to calculate the power consumption.

For example, an air conditioner will have higher consumption than any other device in the RV form factor. You need to determine the starting and running watts of the inverter generator to best match the maximum power consumption.

Fuel Type

Gasoline, propane, and diesel fuel are the main fuel sources for most RV generators.

To choose the best fuel from the range of suggestions above, you need to consider how much it will cost you to be able to operate the machine. The cost issue depends quite a lot on the area you live in and the fluctuation of prices.

Many users agree to pay a large amount of money for a dual-fuel inverter generator model. This unit can run on gasoline or propane, giving you a wider choice of fuel sources. However, you should also note that these devices’ capacity may vary depending on the type of fuel you use.

Tank Size

If you care about generator runtime, one of the most important criteria when choosing is the fuel tank’s size.

A large fuel tank will ensure a longer operating time for the device. Yet, the large size means that the weight of the inverter generator will increase significantly.

Meanwhile, if you appreciate the device’s portability, give preference to products with a moderate fuel tank size. You certainly don’t want to go camping with an inverter generator weighing up to a hundred pounds.

Parallel Capability

In other words, a device with parallel capabilities will support connecting two generators via a dedicated set of connectors.

Thanks to this capability, you will have more power output to meet the power requirements of large appliances such as air conditioners.

Maybe when choosing to buy, you have carefully calculated the amount of power to provide, so you are not too concerned about the device’s connectivity.

However, to meet the increasing demand for use in the future, you should prioritize devices that support parallel connections.


In the past, old models of generators used to operate with a quite loud noise. Nowadays, most portable RV generator models run much quieter. Some of the best quiet generators for RV only produce noise between 50 and 60 decibels.

The above number fluctuates depending on the load you put on the device. You should not be concerned about the noise level that the manufacturer provides.

Sometimes the above parameters are just the minimum, representing the noise level of the device when operating at a load of just equal to a quarter.


If you don’t want to permanently install a generator underneath your RV, you’ll need to take care of its portability.

Typically, portable inverter generator models will weigh no more than 100 lbs. If you want a heavier device, make sure your option has built-in wheels and handles for easy portability.

Warranty Information

You certainly will not want to invest a large amount of money for a generator that can only operate for a short time. That is also why you should consult the manufacturer’s warranty information to protect your rights.

The warranty information will cover the ability to repair problems with the generator. Even in the worst case, the warranty service may include a new replacement of the entire device.

In addition to the terms related to repair and replacement, you also need to pay attention to the warranty period. A longer warranty period will be more reliable, as you can repair or replace the device over a long period of use.

The warranty period also indirectly tells about the quality of the product, while the longer warranty period is a testament to the manufacturer’s confidence in the quality of the device.


Generator prices change frequently. You need to consider the costs incurred outside, such as maintenance costs and fuel consumption of the product.

You should regularly monitor information related to generators on reputable addresses to be able to update the most favorable prices.


Is an inverter generator better for an RV?

The answer is yes. Especially when compared to conventional portable generators, inverter generators are more energy efficient as the motor will automatically adjust to the electrical load.

Will a 3500-watt inverter generator run an RV?

3,500 watts can run your RV. If you would like to run multiple devices simultaneously, you need to calculate the power consumption before operating.

Can I run a 30-amp generator on a 50-amp RV?

With the help of an adapter, you can plug the 30-amp RV cord into a 50-amp power outlet.

Is a 4000-watt generator enough for an RV?

4,000 watts is more than enough to power an RV because even the average RV air conditioner only requires generators of at least 2,000 watts.

What kind of generator is best for an RV?

Inverter generators are one of the best options for RV campers. It is impossible not to mention the quiet operation due to the sealed organs and the built-in smart microprocessor to ensure the safety of electronic devices.

How much does an RV inverter cost?

To buy a good quality RV power inverter model, you will have to spend between $150 and $300. In particular, some inverter models with higher output power and integrated with many other smart features will cost thousands of dollars.


In choosing the best inverter generator for an RV, I considered many criteria, from price and capacity to flexibility and durability. In addition, I also try to give my comments as honestly and objectively as possible.

Each product in the above list has its own advantages. I believe that with the above analysis and guidance, you will find the right product for your needs.
