Description

Zoom on the Honda EB4000X

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

  • RV travellers who wish to upgrade their experience to another level
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Amateur DIY lovers
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals who want to ensure that a power failure will not prevent them from working

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 (and even up to 5000 W thanks to the iAVR technology).

The generator features a conventional pull-start mechanism. It is rated for a noise of 61 dBA (just slightly more noisy than background music).

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 upcoming 6 AC outlets:

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

This Honda generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready.

Portability

The Honda EB4000X has a conventional, open frame design, of the following dimensions: L41.9 x W27.2 x H29.2 in, which offers support and allows it to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

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, which is on the top of the frame, serves as an extra safety feature for the transport, unloading and loading of the device.

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 automatic low oil shut-off (Oil Alert®) and an overload protection (circuit breaker), giving you a peace of mind during use.

Besides the features previously mentioned, accessory-wise, the Honda EB4000X comes with the usual documentation and owner's manual (opens in a new tab) needed to get you promptly started. An official storage cover is available, as a separate purchase.

iAVR Technology

Honda’s iAVR (opens in a new tab) (Intelligent Automatic Voltage Regulation) reduces voltage fluctuation by up to 50% over current AVR systems.

In conventional generators, when a load is applied, the engine’s rpm drops, which causes the voltage and frequency to drop as well, until the rpm recovers.

iAVR is a combination of the DAVR (opens in a new tab) technology and the iGX (opens in a new tab) engine technology, which serves to provide advanced and instantaneous engine rpm control when a load is applied.

As a result, voltage and frequency are precisely regulated and the EB4000X is able to produce a starting wattage above the maximum rating, for up to 10 seconds. Therefore, thanks to iAVR, the EB4000X is able to “overclock” itself above its 4000 starting watts and provide up to 5000 W.

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).

  • Considering its dry weight of 185 pounds, the Honda EB4000X is one of the heavier generators producing between 3000 and 4000 running watts. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
  • As its lowest possible noise is rated at 61 dBA, this generator qualifies as one of the more quiet of the products of similar power. For those who are looking for a less noisy device, we suggest the Cat INV4000E. With just 51 dBA, it is one of the most quiet devices in this power range.
  • Thanks to an impressive running time of around 16 hours at 50% load, the EB4000X benefits from one of the highest run times among generators of a similar output
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.39 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.

The bottom line

STRENGTHS:
  • GFCI Outlets
  • iAVR technology
  • 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
