Discover the largest Honda generators so you can get a lot of power from your favorite brand and the benefits it offers.

Largest Honda generators overview

A quick note is that I did not include large portable generators with just a Honda engine. All the options are completely from this brand.

  1. Honda EB10000 – Largest Honda generator (10000 peak watts, non-inverter)

5 Largest Honda generators reviewed in detail

The largest Honda generators offer a lot of power but you likely care about other details too.

Checking out the detailed reviews of all the options can make your decision easier.

1. Honda EB10000 – Largest Honda generator

The Honda EB10000 is the largest Honda generator with 10000 starting watts, 9000 running watts, and dimensions of 41.0″ L x 27.7″ W x 35.1″ H.

Before investing in this beast you do want to know it generators high THD power.

Honda EB10000

This is not suited for sensitive electronics like microwaves, TVs, and many refrigerators and ACs.

Additionally, the Honda EB10000 noise levels of 71 dBA to 73 dBA at 50% to 100% load may be quiet for a 10000 peak watt generator.

However, to your (and your neighbors’) ears, this will likely be on the louder side.

Pros

  • Honda EB10000 offers 10000 starting watts, 9000 running watts, 50 amps, and 250 volts
  • Run time of 7.9 hours at 50% load
  • Has electric start
  • Four GFCI outlets
  • Has a CO minder
  • 3 years limited residential and 12 months limited commercial warranties

Cons

  • Noise levels of 71 dBA to 73 dBA at 50% to 100% load are somewhat louder
  • High THD is not suited for running sensitive electronics
  • You likely need help moving the weight of 403 lbs (182.8 kg) around
  • Not that many customers yet

As you can expect, the Honda EB10000 is also challenging to move due to its weight of 403 pounds.

There are not that many reviews yet but so far, they are mostly as positive about the reliability as what you would expect from a large Honda generator.

The decent run time of 7.9 hours at 50% load and electric start also make operating the Honda EB10000 relatively convenient.

So if you don’t mind the noise levels and high THD, the Honda EB10000 could be worth the investment for job sites, outdoor events, home backup power, etc.

2. Honda EU7000iS – Largest Honda inverter generator

If your home, food truck, event, etc. has any sensitive electronics, it could be smart to go for the Honda EU7000iS which is the largest Honda inverter generator.

You do want to know that this inverter technology requires a bigger investment.

Additionally, there are still a few exceptional cases where customers have technical issues with the Honda EU7000iS.

That being said, the Honda EU7000iS also still has impressive positive points like its BlueTooth capability.

Pros

  • Honda EU7000iS offers 7000 starting watts, 5500 running watts, 30 amps, and 240 volts
  • Parallel capability
  • Quietest large Honda generator with noise levels of 52 to 58 dBA (25% to 100% load)
  • Nice run time of 16 hours at 25% load
  • Should be less than 3% THD
  • Electric start
  • Remote operation through Honda My Generator app
  • Four GFCI outlets
  • CO sensor
  • Relatively positive customer reviews
  • 3 years limited residential and 12 months limited commercial warranties

Cons

  • Inverter technology adds to the price
  • A few exceptional cases of technical difficulties
  • You may need help moving the weight of 263.2 lb (119.4 kg)

This BlueTooth capability allows you to start, stop, and track the Honda EU7000iS through the Honda My Generator phone app.

The Honda EU7000iS is also very impressive in terms of quiet operation with noise levels of 52 to 58 dBA at 25% to 100% load.

In combination with the run time of 16 hours at 25% load, you can use the Honda EU7000iS to power something like a reasonably-sized AC and/or refrigerator overnight.

So the Honda EU7000iS is a hefty investment but if you really like the Honda brand, low THD inverter power, and quiet operation, this portable generator could be worth it.

3. Honda EM6500SX

Whether the 6500 starting watts and running watts are enough depends on your needs.

However, these capacities do still make the Honda EM6500SX one of the biggest Honda generators available.

Honda EM6500SX

This generator can even offer 7000 watts for 10 seconds to start larger pieces of equipment at your job site, event, or DIY session.

You do want to keep in mind that the Honda EM6500SX and the remaining options are no inverter generators.

To power sensitive electronics with these, you would need your own way to “clean up” the energy.

Pros

  • Honda EM6500SX offers 6500 starting watts, 5500 running watts, 30 amps, and 240 volts
  • Can go to 7000 watts for 10 seconds to start large equipment
  • Relatively low noise levels of 64 dBA to 66 dBA (at 50% to 100% load)
  • Run time of 9.8 hours at 50% load
  • Honda My Generator app connectivity (including remote start)
  • Has electric start
  • Has CO sensor
  • Four GFCI outlets
  • Weight of 231.7 lb (105.1 kg)
  • 3 years limited residential and 12 months limited commercial warranties

Cons

  • High THD is not suited for sensitive electronics
  • Fuel efficiency is not that good
  • A few very exceptional cases of issues

Additionally, the fuel efficiency of the Honda EM6500SX is not that good.

This means you will get a relatively low amount of kWh (energy quantity) per gallon of fuel.

In turn, the power from the Honda EM6500SX will be somewhat pricier in the long term compared to some of the other large Honda generators.

That being said, the Honda EM6500SX could still be worth the investment if the 6500 peak watts (actually 7000 peak watts) are ideal for your needs.

The BlueTooth connectivity and reliability the current customer reviews imply are nice benefits too.

4. Honda EM5000SX

The Honda EM5000SX is not just similar to the previous big Honda generator in terms of name.

You can expect somewhat similar functionality but with fewer running watts too.

Honda EM5000SX

It is interesting to note that Honda built this large generator to be able to provide 7000 peak watts too.

That means the Honda EM5000SX is still able to start relatively big appliances and tools but at a lower price than the Honda EM6500SX.

You also get all this power at reasonable noise levels of 63 dBA to 66 dBA at 50% to 100% load.

Pros

  • Honda EM5000SX offers 5000 starting watts, 4500 running watts, 30 amps, and 240 volts
  • Can go to 7000 watts for 10 seconds to start large equipment
  • Relatively low noise levels of 63 dBA to 66 dBA (at 50% to 100% load)
  • Good run time of 10.5 hours at 50% load
  • Honda My Generator app connectivity (including remote start)
  • Has electric start
  • Has CO sensor
  • Four GFCI outlets
  • Weight of 226.4 lb (102.7 kg)
  • 3 years limited residential and 12 months limited commercial warranties

Cons

  • High THD is not suited for sensitive electronics
  • Not that many customer reviews for now
  • Fuel efficiency is not that good

With these noise levels, the Honda EM5000SX should not disturb your event, food truck activities, job site operation, or neighbors too much.

Two downsides to keep in mind are the high THD power and bad fuel efficiency.

Additionally, even though this should not be too much of a problem with the Honda generator brand, more customer reviews to confirm the reliability is welcome.

That being said, with other good features like the 10.5 hours run time at 50% load, the Honda EM5000SX still looks like a solid large Honda generator.

5. Honda EG4000

The Honda EG4000 is on both the list of largest and smallest Honda generators due to the limited product range.

Whether or not the 4000 starting watts and 3500 running watts of the Honda EG4000 are big enough ultimately depends on your power needs.

Honda EG4000

If the answer to this is yes, the Honda EG4000 can save you some money compared to the other options on this list.

One thing you do want to keep in mind is the somewhat louder noise levels of 66 to 67 dBA 50% to 100% load.

This is likely too much for something like a camping trip and potentially too much for running devices overnight.

Pros

  • Honda EG4000 offers 4000 starting watts, 3500 running watts, 30 amps, and 240 volts
  • Dimensions of 26.8″ x 20.9″ x 22.5″
  • Good run time of 14.8 hours at 50% load
  • Four GFCI outlets
  • CO sensor
  • 3 years limited residential and 12 months limited commercial warranties

Cons

  • Noise levels of 66 to 67 dBA (50% to 100% load) are on the louder side
  • Non-inverter THD power is not suited for running sensitive electronics
  • Optional wheel kit is basically a must with the weight of 146.6 lb (66.5 kg)
  • Not that many customers yet
  • Fuel efficiency is not that good

You will also likely need to invest in the optional wheel kit since the Honda EG4000 has a weight of 146.6 pounds.

Something that positively stands out in the Honda EG4000 is its long run time of 14.8 hours at 50% load.

This allows you to enjoy your power for a long time before doing any refuel sessions.

Overall, I would not describe the Honda EG4000 as one of the best Honda generators.

At the same time, the smaller investment required could still be enough to compensate for suboptimal details in other generator performance areas.
