Description

Zoom on the Honda EB4000X

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

  • RV travellers looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events
  • 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 ensure that a power failure will not prevent them from working

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Honda EB4000X in use

The Honda EB4000X

The Honda EB4000X houses a 270 cc Honda iGX270 OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 3500W along with a peak wattage of 4000W.

The generator is rated for a noise of 61 dBA (just slightly more noisy than an office). Its starting mechanism is based on a simple traditional pull-start mechanism.

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

Outlets

The control panel includes the following 6 AC outlets:

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

While this Honda generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.

Portability

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

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 185 lbs make it incredibly difficult to manually lift and transport. 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.

In addition, the device is equipped with a lift hook on the top of its frame, which provides extra safety during the loading, unloading and transport of the generator.

Features

Panel of the Honda EB4000X

The EB4000X's control panel

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Alert®), giving you a peace of mind during use.

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. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used 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.
  • At a lowest noise rating of 61 dBA, this generator is one of the quieter devices 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 expensive side of the price range.

While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.

The bottom line

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