30 Amp Generator – Which One’s the Best?

A 30 amp generator can be an ideal choice for RV, construction site or household backup power supply.

There are plenty of such generators available in the market but… which one is the best choice?

In our opinion the Champion 3400 Dual Fuel Inverter is the most recommended 30 amp portable generator, closely followed by the Honda EU3000iS.

The main reasons why we’ve ranked the Champion above Honda are:

  •  it’s almost twice as cheap making it a really excellent value for money
  •  it is a dual fuel generator offering you the choice of gas and propane

Both are really excellent generators but when you take these factors into account, Champion is a slightly better choice for most of the users.

Check out our roundup review below to find out more about these and other recommended 30 amp generators.

Champion 3400 Dual Fuel 30 Amp Inverter

Champion 3400 - the best inverter generator width dual fuel capacityThe Champion 3400 Dual Fuel inverter is one of my personal favorite generators.

It’s one of the only few inverter generators offering the choice of two fuels – gas and propane.

Switching fuels is very easy as all you need to do is push the fuel selector dial.

It is also fully RV ready as it comes with the dedicated 30 Amp RV outlet.

There is no need to purchase any additional accessories before you plug it to your travel trailer.

The generator can power most of the RV equipment.

These include:

  • RV Air Conditioning Unit (as large as 15000 BTU)
  • RV Refrigerator & Freezer
  • Lights
  • TV

You could also use it to run various electric work tools such as:

  • Bench Grinder (8’’)
  • Circular Saw (Heavy Duty type)
  • Rotary Hammer
  • Portable Heater (150,000 BTU)

The generator is very fuel-efficient. It can run for around 14 hours on gas and 7 hours on propane at 50% load which is a really good result.

It’s an inverter generator working under the minimum recommended THD (Total Harmonic Distortion) threshold. This makes it ideal for running modern portable electronics.

The generator comes with parallel capability. This means that you can get the optional parallel kit allowing you to connect two inverters together and maximize the total power you get.

Another strong selling point of this generator is its good price. It’s significantly cheaper than Honda generators.

Although it lacks the durability and the quality of finishing of Honda EU3000iS, it should definitely satisfy most of the users.

When we take the price into account, the Champion 3400 is the one to grab the title of the best 30 amp generator.

Honda EU3000iS

If you ask most of the people experienced with portable generators about who makes the best generators out there, a lot of them will answer: Honda.

It’s true that Honda makes some of the strongest and most reliable gensets in the market. Their flagship inverter EU2000i, later succeeded by EU2200i became the synonym of the quality generator.

Honda EU3000iS is another superb quality generator made by Honda.

This 30 amp generator features the original Honda GX200 4-stroke engine – one of the best in the market.

It is one of the strongest inverter generators available. You could easily run a typical RV air conditioner and a few smaller items on top of it.

What I really like about Honda Eu3000is is how quiet it is. At 50% load if produces only around 58 dB of noise which is REALLY silent for the generator of this size.

This is by far the quietest 30 amp generator I have ever found.

EU3000iS has got parallel capability. You can use the parallel kit (purchased separately) to connect two EU3000iS together and double your total power output.

The generator is very simple to use. Besides the manual recoil start, it also has an electric startup. You can turn it on and off with a simple push of a button.

This generator is overall a great and very reliable choice for those who look for the generator for home backup power supply, worksites or RV camping.

The only downsides include the high price tag (all in all it’s Honda…) and the lack of wheels and carrying frame in the kit – you need to purchase these separately.

In any case – this is one of the best 30 amp portable generators and the ideal choice if you need a very sturdy 30 amp inverter generator.

Check out my full review of EU3000is here if you want to learn more about it.

Pros

  • One of the most trusted manufacturers

  • Very strong and durable

  • Super quiet for its size

  • 3-year warranty

Cons

Champion 3800 Dual Fuel

When reading this roundup review you might suspect that we’re biased towards the dual fuel generators.

However, we’ve got plenty of reasons to like them more than many other generators we’ve reviewed.

First, the choice of two fuels is a massive convenience and can be a real game-changer during an emergency when the availability of fuel is key.

Second, it just happens that some of the best 30 amp generators we have researched are the dual-fuel models.

While they might cost a bit more then generators running on gas only, they are more cost-effective in the longer term. They are also more environmentally friendly.

Champion is one of the most recommended companies making these kinds of generators.

The Champion 3800 is a very solid open frame 30 amp generator ideal for a variety of situations.

You could use it to run equipment like an 11,500 BTU air conditioner, freezer, fridge, and lights.

The generator comes with a convenient electric start. Switching the generator on and off happens at a simple push of the button.

The generator has got a very long run time even when operating only on propane. You could expect it to run for up 10 hours depending on the load on a single propane bottle.

While I wouldn’t call this generator a loud one, it certainly is not as quiet as inverter gens. However, if you are looking for a generator for work or emergency home backup, the noise will not be your main concern.

Having said that, with its 69 decibels it’s still less noisy than many older 30 amp portable generators.

Overall this is a very solid gen made by a trusted company known for their good customer support. It’s also a very inexpensive gen selling for reasonable price online.

Pros

  • Easy to use

  • Dual fuel

  • Quite cheap

  • Long run time

Cons

  • Could be slightly quieter
