Best 6000 watt generators top picks

  1. Champion 100519 6250 – Best “6000” watt inverter generator (actually 6250 peak watts)
  2. WEN GN6000 – Best non-inverter 6000 watt generator
  3. GENMAX GM6000IED – Best propane-compatible dual fuel 6000 watt generator and quietest
  4. GENMAX GM6000XIE – More budget-friendly 6000 watt inverter generator
  5. Westinghouse wGen5300DF – Good dual fuel non-inverter with 6600 peak watts

Besides the Westinghouse wGen5300DF, our top picks for this category stick to 6000 and 6250 peak watt generators.

Keep in mind that it is not possible to create one perfect ranking for everyone.

For example, if you don’t necessarily want a 6000 watt inverter generator, the WEN GN6000 can be a more budget-friendly option than the top pick.

5 Best 6000 watt generators reviewed in-depth

People who are in a hurry can use the list of top picks and performance table above to quickly choose a good 6000 watt generator.

You may also want to look at some of the options more in-depth before making your choice.

1. Champion 100519 6250 – Best “6000 watt” inverter generator

I give extra points to generators that actually stay within the 6000 peak watt category but the Champion 100519 6250 is high-quality enough to overcome this and be the best option.

When you get to the higher power levels like 6000 watts and higher, it can be somewhat more challenging to find pure sine wave inverter generators.

Champion 100519 6250

However, the Champion 100519 6250 offers clean low THD energy and does this reliably and at a reasonable price.

The main thing that can be better is that the generator design is somewhat inconvenient for adding oil.

Pros

  • Champion 100519 6250 offers 6250 starting watts, 5000 running watts, 30 amps, and 240 volts
  • Reasonable noise levels of 69 dBA
  • Nice run time of 13.5 hours at 25% load
  • Less than 3% THD
  • In-depth performance tracking
  • Weight of 121 lb (54.9 kg)
  • Relatively positive customer reviews
  • 3 years limited residential and 270 days limited commercial warranties
  • A lot of customers

Cons

  • Fuel efficiency is not that impressive
  • Oil change is somewhat inconvenient

The number of kWH the Champion 100519 6250 gets out of a gallon of fuel aka the fuel efficiency is not that impressive either.

While these things can be better, the Champion 100519 6250 definitely still deserves the top pick for the best 6000 watt generator.

Its weight is reasonable to move around and the in-depth performance tracking makes it easier to estimate when you need to refuel and do maintenance.

And in the unlikely case something does go suboptimal you have the solid 3 years limited residential and 270 days limited commercial warranties to fall back on.

2. WEN GN6000 – Best non-inverter 6000 watt generator

Whether you are investing in a 6000 watt generator or other level, you want to know that there is a difference between inverters and non-inverters.

Technical details aside, inverters like the Champion 100519 6250 top pick provide low THD “clean” energy that is suited for running sensitive electronics.

On the other hand, there are non-inverters like this WEN GN6000 that still offer 6000 watts but with higher THD.

WEN GN6000

Even if you don’t plan to run relatively sensitive devices like a phone or TV, high THD power can speed up the wear and tear of electronics.

Pros

  • WEN GN6000 offers 6000 starting watts, 5000 running watts, 30 amps, and 240 volts
  • Reasonable noise levels of 68 dBA
  • Run time of 7.5 hours at 50% load
  • Weight of 119 lb (54 kg)
  • Relatively positive customer reviews
  • 2 years limited residential and 90 days limited commercial warranties
  • A lot of customers
  • Budget-friendly

Cons

  • High THD power is not suited for sensitive electronics
  • Relatively short commercial warranty
  • A few exceptional cases of early technical challenges

THD details aside, if you plan to run machines that don’t care too much about this or don’t mind the risk of wear and tear, the WEN GN6000 can be the best 6000 watt generator for you.

One of the benefits of non-inverters like this is that they are a lot more budget-friendly than many of the other top picks.

At the same time, customers are also still really positive about the WEN GN6000 with only a few exceptional cases where the generator had technical challenges relatively soon.

Something food truck owners and other small businesses do want to keep in mind is the relatively short commercial warranty of 90 days.

3. GENMAX GM6000IED – Dual fuel and quietest

If you don’t like how the previous 6000 watt generators were gasoline-only and average in noise levels, you could consider the GENMAX GM6000IED.

GENMAX GM6000iED

However, before you do, you want to know that the overall customer reviews are not that positive with how common technical issues seem to be.

These range from less important problems like the tracking screen not working to the generator just not working.

Additionally, GENMAX does not really have a reputation for offering helpful customer support.

Pros

  • GENMAX GM6000IED offers 6000 starting watts, 5250 running watts, 30 amps, and 240 volts (gasoline)
  • Dual fuel feature allows you to run on propane too
  • Quietest 6000 watt generator with 63 dBA
  • Nice run time of 13 hours at 25% load
  • Less than 3% THD
  • Weight of 117.9 lb (53.5 kg)
  • 1 year limited warranty

Cons

  • Customer reviews are not that positive
  • Pricey compared to many 6000 watt generators

That being said, if you absolutely want a 6000 watt dual fuel inverter that can run on propane too, the GENMAX GM6000IED is still your main option.

This model also has its positive points like being the top pick for the quietest 6000 watt generator, a nice run time of 13 hours, and a nice amount of gasoline running watts.

Again, unless you have very specific needs, this GENMAX GM6000IED is likely not the right portable generator for sale for you.

Even if you just don’t necessarily want pure sine wave low THD power, one of the later picks, the Westinghouse wGen5300DF, could be better for you.

4. GENMAX GM6000XIE – Budget-friendly option

When you get to higher power levels like 6000 peak watt generators, there tend to be fewer models to choose from.

Due to this lack of competition, even a not-so-great 6000 watt inverter like the GENMAX GM6000XIE gets a spot on this list.

GENMAX GM6000XIE

At first sight, this could look like a decent powerful inverter with a nice run time, pure sine wave power, and a relatively portable weight.

However, it is important to note that you likely just want to save up a bit more for the Champion 100519 6250 instead.

Pros

  • GENMAX GM6000XIE offers 6000 starting watts, 5250 running watts, 30 amps, and 240 volts
  • Reasonable noise levels of 70 dBA
  • Nice run time of 13 hours at 25% load
  • Less than 3% THD
  • Weight of 106.9 lb (73 kg)
  • 1 year limited warranty

Cons

  • Low number of customers
  • So far not the most promising customer reviews

From the current GM6000XIE customer reviews and some of the other GENMAX portable generators, the risk of technical issues seems relatively high.

Even if you don’t particularly need any home backup power for power outages, you will likely prefer one of the actually good 6000 watt generators for sale.

5. Westinghouse wGen5300DF – Dual fuel non-inverter

When actual 6000 peak watt models are somewhat lacking and slightly higher starting watts like this Westinghouse wGen5300DF are good enough I include them too.

Something important to note first is not this is not an inverter generator. In simpler words, you don’t want to run sensitive electronics like a phone or TV on this generator.

Westinghouse wGen5300DF

However, if you don’t mind this higher THD power and like the idea of being able to get electricity from propane, this Westinghouse wGen5300DF could be the right choice.

The run time of 14.5 hours at 25 load is solid. Especially at the 5300 running watts which is slightly higher than the 6000 watt generators on the list.

Pros

  • Westinghouse wGen5300DF offers 6600 starting watts, 5300 running watts, 30 amps, and 240 volts (gasoline)
  • Dual fuel feature allows you to run on propane too
  • Reasonable noise levels of 68 dBA
  • Nice run time of 14.5 hours at 25% load
  • Weight of 135.6 lb (61.5 kg)
  • 3 years limited residential and 1 year limited commercial warranties
  • A lot of customers
  • Budget-friendly

Cons

  • High THD power (<23%) is not suited for sensitive electronics
  • A few cases of technical issues

You may not want to run the Westinghouse wGen5300DF overnight due to the somewhat higher noise levels.

However, the solid run time does allow you to enjoy your power for longer with fewer refueling sessions.

The number of technical issues is low enough to call these the exceptions. If these do happen you can make use of the warranties included.

In short, people who don’t need an inverter and do need a dual fuel feature can consider the Westinghouse wGen5300DF.

That being said, many people will prefer one of the previous generators.
