4 Smallest 240 volt generators reviewed

Even if you want a small 240v generator, you likely care about things like quality and THD levels too.

The in-depth reviews below can help you find the best option for your preferences and needs.

1. Honda EG4000 – Smallest 240v generator

The Honda EG4000 is the smallest 240 volt generator with 4000 peak watts and dimensions of 26.8″ L x 20.9″ W x 22.5″ H.

However, you likely don’t actually want to invest in the Honda EG4000 for a few reasons.

Honda EG4000

First of all, this 240 volt generator is relatively expensive compared to the other options on this list.

In theory, pricey Honda generators do come with good reliability to compensate.

When it comes to the Honda EG4000, you can not say for sure yet with the small number of customer reviews.

Pros

  • Honda EG4000 offers 4000 starting watts, 3500 running watts, 30 amps, and 240 volts
  • Dimensions of 26.8″ L x 20.9″ W x 22.5″ H
  • 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

  • Expensive compared to other 240 volt generators
  • 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

Additionally, a few of these reviews note the noise levels of the Honda EG4000 are relatively loud (66 to 67 dBA at 50% to 100% load).

In turn, running this small 240v generator overnight is likely not recommended if you and your neighbors want to be able to sleep.

Additionally, the Honda EG4000 is not an inverter generator.

To be able to run electronics like a TV and many air conditioners and refrigerators, you would need your own way to “clean up” the power.

The Honda EG4000 has positive points too but you will likely agree that these are not enough with how good some of the other smallest 240 volt generators are.

2. Predator 4375

The Predator 4375 may not be perfect but it is a small 240 volt generator you can actually consider investing in.

One thing to note first is that the Predator 4375 is another high THD generator.

This should be OK for devices like well pumps but for electronics like a TV or many AC systems, you want to go to the bonus option.

Additionally, the Predator 4375 is relatively loud with a decibel rating of 72.5 dBA.

You likely don’t want to use this 240 volt generator on a crowded camping or in a small neighborhood.

Pros

  • Predator 4375 offers 4375 starting watts, 3500 running watts, 30 amps, and 240 volts
  • Dimensions of 23.33″ L x 18.66″ W x 19.25″ H
  • Good run time of 16 hours at 50% load
  • Weight of 105 lb (47.6 kg)
  • Four GFCI outlets
  • Has a CO sensor
  • Relatively positive customer reviews
  • 2 years limited emissions control system and 90 days limited product warranties
  • Budget-friendly

Cons

  • Relatively loud noise levels of 72.5 dBA
  • Non-inverter THD power is not suited for running sensitive electronics
  • Short warranties
  • Wheel kit bought separately
  • A few exceptional cases of technical issues

The short warranties, the wheel kit that is not included, and the exceptional cases of technical issues are not ideal either.

That being said, if you don’t mind these things too much, the Predator 4375 is still a solid and budget-friendly option overall.

For example, the 16 hours run time at 50% load is definitely impressive.

This allows you to enjoy your power for longer before having to do a refuel session.

Additionally, the four GFCI outlets and CO sensor add an extra layer of safety to the Predator 4375.

3. DuroMax XP4400EH – Smallest 240v dual fuel generator

The DuroMax XP4400EH is the smallest 240v dual fuel generator out there.

For people who are not that familiar with portable generators, this means the DuroMax XP4400EH can run on both gasoline and propane.

DuroMax XP4400EH

One of the benefits of propane is that it typically stores longer than gasoline.

This makes being prepared for power outages and off-grid living more convenient.

Additionally, if you only plan to use your 240 volt generator occasionally, propane tends to involve less maintenance.

Pros

  • DuroMax XP4400EH offers 4400 starting watts, 3500 running watts, 30 amps, and 240 volts
  • Dimensions of 25″ L x 24″ W x 21″ H
  • Good run time of 25 hours at 25% load (gasoline)
  • Good gasoline fuel efficiency
  • Weight of 122 lb (55.3 kg)
  • Has electric start
  • Four GFCI outlets
  • 3 years limited residential and 1 year limited commercial warranties
  • A lot of customers

Cons

  • Relatively loud noise levels of 69 dB
  • Non-inverter THD power is not suited for running sensitive electronics
  • A few exceptional cases of technical issues
  • User manual can be better

And if you don’t need the dual fuel feature but like the other details of the DuroMax XP4400EH, you can also go for the more budget-friendly gasoline-only DuroMax XP4400E.

Both of these non-inverter generators have good run times of 25 hours at 25% load, good gasoline fuel efficiency, and an electric start.

These things make operating the DuroMax XP4400EH a bit more convenient and can save you some money on gasoline in the long term.

In short, if you like the dual fuel feature and/or the gasoline fuel efficiency and don’t need low THD power, the DuroMax XP4400EH is worth considering.

If not, you will likely prefer one of the other small 240 volt inverter generators on the list.

4. GENMAX GM5500i – Smallest 240v inverter generator

With 5500 peak watts and dimensions of 24″ L x 18.5″ W x 21.1″ H, the GENMAX GM5500i gets the top spot for the smallest 240 volt inverter generator.

That being said, for many people and situations, this is another generator that is likely not worth it.

GENMAX GM5500i

The main reason for this is the somewhat high rate of technical issues.

Especially if you plan to use your 240v generator as backup power, this is a big downside.

Additionally, even with this rate of technical issues, the GENMAX GM5500i is not the cheapest generator either.

Pros

  • GENMAX GM5500i offers 5500 starting watts, 5000 running watts, 30 amps, and 240 volts
  • Dimensions of 24″ L x 18.5″ W x 21.1″ H
  • Relatively low noise levels of 62 dBA
  • Nice run time of 13 hours at 25% load
  • Less than 3% THD
  • Has electric start
  • Four GFCI outlets
  • CO sensor
  • Weight of 127.8 lb (58 kg)
  • 1 year limited warranty

Cons

  • Relatively short warranty
  • Decent number of technical issues
  • Moving the generator over uneven terrain can be challenging

On the flip side, you do want to know that the GENMAX GM5500i has positive points like for example being a relatively quiet 240v generator.

Since a regular conversation is around 60 decibels, 61 dBA could be quiet enough to run devices overnight.

This includes electronics like a refrigerator or air conditioner because the GENMAX GM5500i is an inverter generator.

Additionally, you could theoretically consider the GENMAX GM5500i if you really care about compact dimensions too.

Bonus: Champion 100519 – Best small 240v inverter generator

Because the GENMAX GM5500i is not that great but many people are interested in 240 volt inverter generators, I included the high-quality Champion 100519 6250 as a bonus option.

6250 peak watts may not fit every definition of small.

Champion 100519

However, with its budget-friendly price, low THD power, and reasonable dimensions, many people will find the Champion 100519 6250 a great pick anyway.

The main thing you do want to keep in mind is that the Champion 100519 6250 is still relatively loud at 69 dBA.

Pros

  • Champion 100519 offers 6250 starting watts, 5000 running watts, 30 amps, and 240 volts
  • Dimensions of 26.6″ L x 25.6″ W x 23.7″ H
  • Nice run time of 13.5 hours at 25% load
  • Less than 3% THD
  • 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

  • Noise levels of 69 dBA are relatively loud
  • Oil change is somewhat inconvenient

That being said, if these noise levels are still acceptable to you, the Champion 100519 6250 positively stands out in its good reliability.

In combination with the inverter power, this generator can be extra great as backup power for a fridge and/or freezer full of food or certain types of 240 volt devices you have at home.

The run time of 13.5 hours at 25% load may not be the longest on the list.

However, this should still be enough to run reasonably-sized devices overnight.

In short, if you are looking for the best “small” 240 volt inverter generator, the Champion 100519 6250 is likely the option for you.
