The Best 30 Amp Generators at a Glance:

Check the comparison table for more details.

What is a 30 Amp Generator and How Does It Work?

This is a generator with a 30 amp outlet. A 30 amp outlet has 3 lines. One of them is a 120v hot wire, and then there’s a neutral and ground wire. This outlet is capable of supplying 3600 watts (30 amps*120v). This is more or less an estimate, though. Some generators will trip at around 2880 watts, which is 80% of 3600 watts, while others will allow you to draw up to 4320 watts, which is 20% more.

Now, the 30 amp outlet is not the only port that you’re going to find on these generators. As you’ll note in these 30 amp generator reviews, most of the contenders also have at least one 20 amp outlet, a 12-volt DC battery charger, and even a USB port for your low power handheld devices.

How to Choose the Right Size 30 Amp Generator?

When selecting the best 30 amp generator, you should understand that most of them don’t go past 3600 running watts. That being said, I’d advise you first to define where you want to use the generator and what you intend to power with it.

For instance, if you are planning to use it in your RV, it’s paramount that you first consider your appliances and ensure that the generator is able to meet their power needs.

Another important consideration is the type of fuel. Most generators use gasoline. But a few of them also allow you to switch to propane, and I find this super convenient.

Also, don’t forget to consider the runtime in relation to the fuel tank size. A generator that runs for a long time per gallon of gas is not only economical, but it also saves you the inconvenience of regular refills.

Lastly, since portability is of the essence, be sure to consider its physical size, weight, and how easy it is to move around. For instance, is there a handle? Does it have wheels?

Now when you have some idea what to look for in a generator, let’s check which are the top 30 amp portable generators on the market at the moment.

 Champion 100302 RV-Ready Generator

  • Long runtime
  • Relatively quiet
  • Versatile power outlet kit

Run Time 17 hrs @ 25% load
Dimensions (in) 21 x 18 x 18
Weight (lbs) 81.5

At the surface, the Champion 100302 looks like a typical traditional open flame generator.

Frequently Asked Questions

How many watts is a 30 Amp generator?

Theoretically, a 30 amp generator outputs 3600 watts of continuous power. However, depending on the size of the engine, some generators may supply as low as 2800 watts while others go slightly higher to output up to 3800 watts.

What is the difference between 50 Amp and 30 Amp generators?

The primary outlet in a 50 amp generator has 4 wires that comprise two 120v live wires, a neutral wire, and a ground wire. As such, it’s possible to pull up to 12000 watts from a 50 amp outlet (50 amp*120*2). On the other hand, the main outlet of a 30 amp generator has 3 wires; one 120v live wire, a neutral wire, and ground wire. The highest number of watts that you can draw from this outlet is 3600 watts (30 amps*120v).

What can you run on a 30 amp generator?

A generator with a 30 amp plug will power pretty much anything provided it does not exceed the generator’s stated running watts, which is usually around 3600 watts. You can run a 15000 BTU AC in your RV and even a freezer and a refrigerator at home.

What size wire for a 30 amp generator plug?

In generator wire sizing, the rule of thumb is a 10-gauge 3-conductor wire for a 30 amp generator.

Are 30 amp generators suitable for commercial use?

Yes, some generators with 30 amp outlets are usable in commercial outlets. However, since you’re likely to be dealing with medium-to-heavy duty appliances, I’d advise you to consider a more powerful generator that is capable of handling higher power loads safely.


So, what is the best 30 amp generator to buy this year? This boils down to personal preferences, and I believe there’s a perfect generator for your needs in the reviews above. However, if you’re open to suggestions, I would highly recommend the Westinghouse iGen4500DF.

First, the versatility of switching from gasoline to propane alone is priceless. But what’s more, is the 18-hour runtime that this generator offers when running on gasoline. Regarding ease of use, this generator is a breeze to set up, and it has a LED display for all the information that you need. Lastly, if the ability to switch ON/OFF remotely sounds good, this is the only 30 amp generator that offers this versatility in these reviews.
