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 outdoor fairs, festivals or events
- DIYers who wish to improve their efficiency with tools
- Homeowners in need of an emergency backup power for their essentials
- 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's design includes a gasoline-fueled 270 cc Honda GX270 OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 3500W and also 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 full tank, the EG4000CL can operate for around 14.8 hours at 50% load (fuel consumption around 0.43 GPH), thanks to its fuel capacity of 6.3 gallons.
The control panel features the following 6 AC outlets:
While this Honda generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.
The Honda EG4000CL has the following dimensions: L26.8 x W20.9 x H22.5 in. In combination with its conventional, open frame design, they provide support and allow 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. Thus, you may also want to consider purchasing its official wheel kit (opens in a new tab).
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Alert®), allowing you to use it with a peace of mind.
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. An official storage cover is available, as a separate purchase.
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).
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.
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, so it is adequate for use in forested areas.
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).
- A weight of 146.4 lbs makes the Honda EG4000CL one of the heavier devices in the 3000-4000 rated wattage range. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
- The generator can be considered average in its noise for its power category, as it is rated at 66 dBA. If noise emissions are one of your priorities, you may be interested in the Cat INV4000E, one of the least noisy generators similarly powerful as this one, rated for 51 dBA.
- Thanks to an impressive running time of around 14.8 hours at 50% load, the EG4000CL benefits from a higher run time than many generators of a similar output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000X, reaching 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. This generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.43 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 GPH and thus, is one of the most efficient devices in our database.
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.

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.
