Description

Zoom on the Honda EG4000CL

In summary, the Honda EG4000CL is a portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • DIYers who wish to improve their efficiency with tools
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals in need of safely powering high-intensity work or lighting equipment

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Honda EG4000CL in use

The Honda EG4000CL

The Honda EG4000CL 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 a normal conversation), the generator features a conventional pull-start mechanism.

The EG4000CL can operate for around 15.7 hours at 50% load with a full tank (fuel consumption around 0.4 GPH), due to its fuel capacity of 6.3 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

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 L26.8 x W20.9 x H22.5 in, the conventional, open frame design of the Honda EG4000CL offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

Since the generator weighs 148 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable).

Features

The EG4000CL'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 automatic low oil shut-off (Oil Alert®) and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

Besides the features previously mentioned, accessory-wise, the Honda EG4000CL comes with the usual documentation and owner's manual (opens in a new tab) needed to get you promptly started.

CO Minder (new model)

Panel of the Honda EG4000CL with CO Minder

The control panel of the CO Minder version is slightly different

Note: The CO Minder is a new feature introduced in 2020 that is not yet present in all EG4000CL units. Make sure to select the "With CO Minder" tab above our retailers list if you wish to benefit from this feature.

Honda's CO Minder is a system that monitors the ambient carbon monoxide concentration, and automatically stops the engine if the sensor detects a CO level of or exceeding 800 parts per million (ppm) at a given time, or an average of 400 ppm for 10 minutes.

A CO alarm indicator will flash for about five minutes, during which it will be impossible to restart the engine.

While it’s a welcomed additional security feature, remember to always take your generator outside (opens in a new tab).

DAVR Technology

Honda’s DAVR (opens in a new tab) 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 EG4000CL 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.

Product Video

The Honda EG4000CL versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Honda EG4000CL compare to generators of similar power (between 3000 and 4000 W).

  • With its weight of 148 lbs, the Honda EG4000CL 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.
  • As this generator can emit noise as low as 66 dBA, it finds itself in the average expected noise for this kind of power. If noise emissions are important to you, one of the least noisy generators of this power range is the Cat INV4000E with only 51 dBA.
  • Thanks to an impressive running time of around 15.7 hours at 50% load, the EG4000CL benefits from a higher run time than many generators of a similar output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000X, boasting with around 16 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.4 GPH. 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 interactive chart, when compared to other 3000-4000W generators, the Honda EG4000CL 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

What is the difference between the EG4000, the EG4000CL, the EG4000CLAT1 and the EG4000CLAG?

The final "G" in "EG4000CLAG" indicates that the unit includes the CO Minder technology. Regarding the rest of the model names, as a rule of thumb, they refer to the unit itself, but simply include more or less information regarding its specs, production batch, etc. Read how Honda name their generators.
