Description

Zoom on the Honda EG4000CL

In a nutshell, the Honda EG4000CL is a portable generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • 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 able to use the most necessary devices in their household, even during a blackout
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 EG4000CL in use

The Honda EG4000CL

The Honda EG4000CL's core is the 270 cc Honda GX270 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.

The generator features a conventional pull-start mechanism. It is rated for a noise of 66 dBA (less noisy than a normal conversation).

With a fuel capacity of 6.3 gallons, the EG4000CL may run for around 14.8 hours at 50% load with a full tank (fuel consumption around 0.43 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 dimensions of the Honda EG4000CL, which are L26.8 x W20.9 x H22.5 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 146.4 lbs make it incredibly difficult to manually lift and transport. To enhance the generator's mobility, it is worth considering purchasing an official wheel kit (opens in a new tab).

Features

Panel of the Honda EG4000CL

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

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 EG4000CL's box includes the typical documentation and an owner's manual (opens in a new tab), letting you start it right off the bat. An official storage cover is available, as a separate purchase.

CO Minder

CO Minder of the Honda EG4000CL

CO Minder monitors the ambient CO concentration

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. Thus, selling and purchasing this generator is allowed in each 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).

  • Considering its dry weight of 146.4 pounds, the Honda EG4000CL 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.
  • Since the generator's noise is rated at 66 dBA, it has the roughly average expected noise for a device 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.
  • As the EG4000CL features an autonomy of around 14.8 hours at 50% load, it has a higher run time than an average generator of its power range. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Predator 4375, as it provides 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. 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 0.43 GPH. 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 EG4000CL 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

What is the difference between the EG4000, the EG4000CL, the EG4000CLAN and the EG4000CLAG?

The final "G" in "EG4000CLAG" indicates that the unit is CARB-compliant. The final "N" in "EG4000CLAN" indicates that the unit cannot be sold in California. 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.
