Description

Zoom on the Honda EG4000

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

  • RV travellers looking for even more independence
  • Amateur DIY lovers
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • 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 EG4000 in use

The Honda EG4000

The Honda EG4000 is powered by a 270 cc Honda GX270 OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 3500W as well as a peak wattage of 4000W.

With a noise rating of 66 dBA (less noisy than background music), the generator features a conventional pull-start mechanism.

Thanks to a fuel capacity of 6.3 gallons, the EG4000 can operate for around 15.7 hours at 50% load with a full tank (fuel consumption around 0.4 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

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

Portability

The design of the Honda EG4000 is a typical, open frame, with the dimensions of L26.8 x W20.9 x H22.5 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 148 pounds.

Features

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

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

As for its accessories, apart from the previously mentioned features, the Honda EG4000 also comes with the basic documentation and a user manual, allowing you to start it right away.

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 and therefore, can be used in forested areas.

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).

  • Considering its dry weight of 148 pounds, the Honda EG4000 is one of the heavier generators producing 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.
  • This generator has a somewhat average expected noise for its power range, rated at 66 dBA. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • Since the EG4000 boasts with a run time of around 15.7 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EB4000, which is able to run for around 16 hours.
  • 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. 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 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.

Price comparison

As you can see from this dynamic 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
