Description

Zoom on the Honda EG4000

In summary, the Honda EG4000 is a portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • 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

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 EG4000 in use

The Honda EG4000

The Honda EG4000 houses a 270 cc Honda GX270 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 features a conventional pull-start mechanism. It is rated for a noise of 66 dBA (less noisy than background music).

With a fuel capacity of 6.3 gallons, the EG4000 may run for around 15.7 hours at 50% load with a full tank (fuel consumption around 0.4 GPH).

Outlets

The control panel provides the upcoming 6 AC outlets:

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

Even if this Honda generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle.

Portability

With its dimensions of L26.8 x W20.9 x H22.5 in, the conventional, open frame design of the Honda EG4000 offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 148 lbs make it incredibly difficult to manually lift and transport.

Features

Panel of the Honda EG4000

The EG4000'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.

As for its security measures, the device features an automatic low oil shut-off (Oil Alert®) and an overload protection (circuit breaker), letting you use it with a peace of mind.

Regarding its accessories, besides the aforementioned features, the Honda EG4000's box includes the typical documentation and an owner's manual, letting you start it right off the bat.

DAVR Technology

Honda’s DAVR technology (Digital Automatic Voltage Regulation) holds the voltage stability within a ±1% change during operation and thus, offers a more stable voltage than conventional generators. This results in better performance, and better protection of your tools.

The DAVR has a built-in, self-diagnosis function to prevent engine speed from exceeding 4,140 rpm for longer than three seconds and abnormal voltage. Additionally, a built-in temperature protection system protects the generator from overheating.

Emissions

The Honda EG4000 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, so it is adequate for use in forested areas.

Product Video

The Honda EG4000 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Honda EG4000 compare to generators of similar power (between 3000 and 4000 W).

  • At a dry weight of 148 pounds, the Honda EG4000 is one of the heavier devices which can produce between 3000 and 4000 running watts. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
  • Since the generator's noise is rated at 66 dBA, it has the roughly average expected noise for a device of similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Westinghouse iGen4500, whose lowest noise levels reach just 52 dBA.
  • The EG4000 provides a higher run time than similarly powerful devices, reaching around 15.7 hours at 50% load. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Honda EB4000, with around 16 hours .
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.4 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 3000-4000W generators, the Honda EG4000 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
  • DAVR technology
  • High run time
AVERAGE SPECS:
  • Acceptable noise (66 dBA)
WEAKNESSES:
  • No data center
  • No electric start
  • On the heavy side (148 lbs)
  • Low fuel efficiency
