3000 Watt Generators – Which Are Best?

Keeping your equipment, tools, appliances, and devices all powered up when you’re on the go can be difficult. In order to do so, you need to ensure that you’ve got access to a good portable generator.

A 3000-watt is a very favored category of generator size, mainly because they can provide a lot of power like larger generators can, but still manage to be just as portable and lightweight as some of their smaller and less powerful counterparts.

The vast majority of 3000-watt generators that are available on the market today are inverter generator. An inverter is an especially important feature to make sure is installed in a generator of this size. The main reason for this is the down to the fact that you’ll most likely want to plug in small, sensitive devices to the generator.

Smaller, more sensitive devices require power that’s suitable for them. This is power with absolute minimal harmonic distortion.

To make it as easy as possible to find the best 3000-watt generator for your needs, we’ve compiled a list of those that we believe to be the best. For each product, we’ll examine exactly what we like about the generator, how much power it’s able to output, as well as the points which we believe could be improved.

We’ll also take a look at how efficient each unit is, in terms of how many hours they are able to run for from how many liters of fuel. We’ll also look at how much noise each generator outputs, and generally how refined they are.

Hopefully, after reading our post, you’ll have a better idea of which 3000-watt generator is best suited to your needs. Perhaps, you’ll even realize that you don’t need as powerful a unit as 3000-watts, or that you need more!


Honda EU3000iS

Honda is a very well-known brand, and as is the EU3000iS that is made by Honda.

The EU3000iS is a powerful 3000-watt generator, with a running output of 2800 watts. This generator isn’t just suitable however for powering large and powerful appliances. It’s fitted with an inverter, which means that the power from it can be used directly with smaller devices.

The EU3000iS is a very refined unit. It’s extremely quiet and only weighs 131 pounds too. It can be moved easily by two people to any location at which it’s needed. If there aren’t two people available to move the generator, it can be easily moved by one using the optional wheel-kit that can be fitted to the generator.

The EU3000iS can be connected in parallel with another generator too. This is particularly useful if the running wattage of 2800 watts from one EU3000iS isn’t enough. You can easily connect another one to the unit, and gain a large total power output.

Key Features

  • 3000 watts of starting power
  • 2800 watts of running power
  • Very Refined – the EU3000iS has a running volume of as low as 49 decibels. This is quieter than the average conversation between two people. It’s the quietest generator that we have ever reviewed
  • Fuel Efficient – Honda have fitted their Eco-Throttle system into the EU3000iS. This system allows the engine to only run at the speed that is necessary to provide the power output being used at the time
  • Inverter Generator – the inverter that’s fitted within the EU3000iS ensures that the power that it outputs is of very high quality. The power from the EU3000iS is just as suitable for powering a heater as it is a mobile phone battery



  • Could be lighter
  • Expensive


Champion Power Equipment 75537i

The 75537i from Champion is a powerful, yet portable unit. It’s one of the best generators in the 3000W power class, and as always, Champion Power Equipment has made this unit a very safe generator to use indeed.

The 75537i has a starting wattage of 3100 watts, and a continuous output of 2800 watts. It’s also very fuel efficient – when being used at 25% load, it will keep running for 8 hours from only 1.5-gallons of fuel.

Although the generator does weigh in at 95 lbs in weight, it comes as standard with a pulling handle and wheel kit. Moving the 75537i around is very easy indeed. The wheels that are fitted to the bottom of the unit are extremely durable and can be pulled over a variety of different terrains without getting flat.

There are numerous uses for the 75537i. For example, it would serve well for a generator being used for tailgating – it has more than enough power. It’s also a great generator for taking camping, or for using alongside an RV for example.

It’s a refined unit that runs at only 58 decibels. It’s got an inverter fitted too, which means the power that’s output by the 75537i is of very high-quality with minimal harmonic distortion. It’s therefore just as suitable for use with small devices and appliances as it is for use with large pieces of equipment. It’s a very versatile unit indeed.

Key Features

  • Starting wattage of 3100 watts
  • Continuous wattage of 2800 watts
  • Electric Starter
  • Remote Start
  • Efficient – up to 8 hours of run time from just one tank of fuel
  • Quiet – running at only 58 decibels, the 75537i is extremely quiet and isn’t intrusive
  • Inverter Generator – the power that’s output from the 75537i has very minimal harmonic distortion
  • 3-Year Limited Warranty from Champion



  • The fuel tank isn’t quite as large as some of its competitors
  • No 240V power outlet


Briggs & Stratton 30545 P3000

Briggs & Stratton are well-known for making very high-quality products. Ever since its establishment, Briggs & Stratton have developed new concepts in many areas of engines and power generation. The P3000 is certainly a representation of this knowledge and innovation.

The 30545 P3000 from Briggs & Stratton is a powerful unit. It’s got a maximum output of 3000 watts and will provide continuous power at 2600 watts. It’s got sufficient power to keep a number of small appliances going at the same time, or a couple of larger ones.

The P3000 is also RV-Ready – it’s got a socket that adapted just for this.

This Briggs & Stratton unit, whilst weighing in at 96 pounds, is also very portable. It comes as standard with a handle and wheel kit, which makes pulling the generator around very easy.

The fuel-efficiency of the P3000 is pretty impressive too, being able to keep running for up to 10 hours when being used at 25% load, from just a single 1.5-gallon fuel tank.

Being a Briggs & Stratton generator, the P3000 is not short of fancy features. It’s fitted with an LCD screen on its control panel that shows the amount of energy that the generator is outputting at any one time, as well as an estimation of how many hours are left in the generator in relation to how much fuel is left.

If you’re interested in the Briggs & Stratton P3000, we’ve included it in our review of the best RV generators too.

Key Features

  • 3000 watts maximum power
  • 2600 watts running power
  • Efficient – automatic idle control and an efficient engine ensures that the P3000 can keep going for up to 10 hours
  • Parallel Connection Available
  • LCD Screen
  • Portable – comes with a durable wheel kit and handle
  • Inverter Generator



  • Users have reported the generator to be louder than is stated



The Briggs & Stratton P3000 is a great generator that’s RV-ready. It’s very efficient and can be connected in a=parallel with another Briggs & Stratton unit for added power. We love that the P3000 comes with added features such as an informative LCD display, too. At less than $900, the P3000 is a unit that offers true value-for-money too.

The Champion 75537I is another favorite of ours. It’s very well-priced and is crammed full of safety features. We love the fact that it’s got a remote starter fitted too – not a feature usually found on generators in this power band. However, it’s not quite as efficient as some of its competitors and doesn’t come with a 240V outlet.

In our opinion, the Honda EU3000iS is the best 3kW generator that you could buy. Even though its quality and features do come at a bit of a price premium, it’s more than worth it in our opinion. It is easily the quietest gas-powered generator that we have reviewed. The EU3000is offers an extremely refined and silent experience and great build quality. It’s a durable and reliable generator.
