The Top 3 30A Generators Examined

If you are looking for a good source of power on the move, a 30 amp generator can be a great option. In this post, we are going to take a look at a few of the best 30 amp generator is available and what they have to offer.

Choosing a good generator can be a challenging task, particularly if you are not all that informed on what features you should and should not be looking for. For each generator that we recommend, we will look at the various design aspects, performance, noise level and value for money.

Briggs & Stratton P3000 – 30 Amp Portable Generator

The Briggs & Stratton P3000 is a well designed, portable RV-ready generator. Considering it’s small and portable nature, it’s a very powerful generator.

The P3000 is fitted with a handle fitted and wheels that make it very easy to move around to any location. The wheels on this generator have been specifically designed to not suffer from punctures too.

The P3000 has a surge wattage of 3000 watts and a continuous running power of 2600 watts. This is more than enough power to run any normal sized air conditioning unit or heater in an RV, as well as larger appliances around the home and garden.

The 171cc engine fitted within the P3000 will keep running for up to 10 hours from 1.5 gallons of gasoline when being used at 25% load.

The P3000 has a screen fitted to its control panel that informs the user of various important numbers. These include the amount of energy the generator is outputting, and a number that shows how many hours are left from the current fuel load – this number is based on current usage and should not be taken as a definite.

The Briggs & Stratton P3000 is an inverter generator, meaning that the power output by it is safe to use with just about any device, no matter how sensitive it may be.  The inverter in this generator makes the current being output very clean and stable – it has less than 3% total harmonic distortion. As well as being a great option for camping and using as support for an RV, the P3000 is perfect for tailgating and providing backup power for your appliances at home, should there be a power cut. It’s a very versatile unit. 

Key Features

  • Economic –  The P3000 has an automatic idle control feature fitted, meaning that it will only run when it needs to provide power
  • Parallel Connection Available – if you would like to, you can combine the forces of your P3000 with another P3000, or indeed a P2200. This allows you to spread the load of a larger appliance, or simply to get a greater total power output
  • 3000 watts starting power
  • 2600 watts running power
  • LCD screen
  • Portable – the P3000 is fitted with wheels and a retractable handle
  • Inverter Generator – the power output by the P3000 has very little total harmonic distortion, ensuring a clean and smooth output that’s suitable for all kinds of device/appliance


  • Changing oil has been reported difficult by some users


Champion 75537i – The Most Portable 30A

The Champion Power Equipment 75537I is a gas powered inverter generator. It’s got a great number of features, such as electric starting and low oil level detection. Champion is well-known for making high-quality units that are as safe as possible to use – the 75537i upholds this reputation pretty well in our opinion.

The 75537i is portable, weighing in at 95 pounds. If this is a bit too heavy to lift, it also comes fitted as standard with wheel kit and handles. The wheel kit that’s fitted to this generator from champion power equipment is designed to be tough and hard-wearing, being fitted with tires that resist puncture. The 75537i is therefore very versatile in that is can be moved over a wide variety of terrain.

The 75537i is a powerful unit. It’s able to put out a surge wattage of 3100 watts and has a running power of 2800 watts. The 75537i is fuel-economic too – it can keep going for up to 8 hours from only one 1.5 gallon tank of fuel when being used at 25% load.

The 75537I a very quiet and refined generator. It runs at only 58 decibels due to the mufflers and soundproofing fitted by Champion.

Since it’s an inverter generator, the power from the 75537i is suitable for powering all sizes of device or appliance.

Key Features

  • Electric Start Button– no need to worry about recoil starts with the Champion 75537I. It’s fitted with an electric start button, making cold starts effortless.
  • Remote Start – the 75537i can be started remotely.

  • Quiet and Refined– the 75537I operates at only 58 decibels, it’s one of the quietest in its class.
  • Inverter – the inverter that’s installed in this generator makes the power that it outputs just as suitable for powering large appliances, as it is small and sensitive devices.


  • No 240V power socket
  • Quite heavy

We think the Champion 75537i is a great unit for tailgating too, as we say here in the best generators for tailgating.

The Briggs & Stratton P3000 is a great portable 30A generator for use alongside an RV. It’s very popular with campers as it’s portable, isn’t too heavy, and is very powerful. The power that it puts out is of high quality too. It’s also fitted with some very nice and uncommon extras, such as an LCD screen. It’s very well-priced too, at $800.

The 75537i from Champion Power Equipment is a versatile 30A generator. It’s not quite as good value as the P3000 however, at almost $950.

The Yamaha EF3000iS is by far the most efficient generator on our list. It is our favorite 30A generator, mainly due to its unbelievable efficiency. It’s got a staggering runtime of up to 18 hours. For generators in this power category, this is especially important. The EF3000iS isn’t by any means a cheap unit, but it’s an investment that will pay off.
