Description

Zoom on the Honda EB4000X

In a nutshell, the Honda EB4000X is a portable generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Amateur DIY lovers
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals who want to be able to deliver results, even during a power failure

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Honda EB4000X in use

The Honda EB4000X

The Honda EB4000X's core is the 270 cc Honda iGX270 OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 3500W and a peak wattage of 4000W.

With a noise rating of 61 dBA (just slightly more noisy than an office), the generator features a conventional pull-start mechanism.

Thanks to a fuel capacity of 6.2 gallons, the EB4000X can operate for around 16 hours at 50% load with a full tank (fuel consumption around 0.39 GPH).

Outlets

The control panel features the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 20A (L14-20R) receptacle

This Honda generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor.

Portability

With its dimensions of L41.9 x W27.2 x H29.2 in, the conventional, open frame design of the Honda EB4000X offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

As the generator's weight is 185 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.

A lift hook located on the top of the frame offers an additional safety feature while facilitating the transport, loading and unloading of the generator.

Features

Panel of the Honda EB4000X

The EB4000X's control panel

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Alert®), which gives you a complete peace of mind when using it.

Along with the aforementioned features, from an accessory standpoint, the Honda EB4000X's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly.

Emissions

The Honda EB4000X is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.

The Honda EB4000X versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Honda EB4000X compare to generators of similar power (between 3000 and 4000 W).

  • With its weight of 185 lbs, the Honda EB4000X is one of the heavier generators in the 3000-4000 rated wattage category. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
  • With a lowest noise rating of 61 dBA, the generator is one of the more quiet of the generators of similar power. If you are concerned with noise, check out the Cat INV4000E, which is one of the least noisy generators in its power range, with a noise rating of just 51 dBA.
  • As the EB4000X features an autonomy of around 16 hours at 50% load, it has one of the highest run times in comparison to the other generators of its power range.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.39 GPH at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.

Price comparison

As you can see from this interactive chart, when compared to other 3000-4000W generators, the Honda EB4000X is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

The bottom line

STRENGTHS:
  • In the expected price range
  • GFCI Outlets
  • Quiet for its power (61 dBA)
  • High run time
WEAKNESSES:
  • No data center
  • No electric start
  • On the heavy side (185 lbs)
  • Low fuel efficiency
