Zoom on the Honda EB4000
In summary, the Honda EB4000 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 EB4000 is powered by a 270 cc Honda iGX270 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 (and even up to 5000 W thanks to the iAVR technology).
The generator features a conventional pull-start mechanism. It is rated for a noise of 61 dBA (just slightly more noisy than an office).
The EB4000 can operate for around 16 hours at 50% load with a full tank (fuel consumption around 0.39 GPH), due to its fuel capacity of 6.2 gallons.
The control panel includes the following 6 AC outlets:
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.
The design of the Honda EB4000 is a typical, open frame, with the dimensions of L41.9 x W27.2 x H29.2 in, offering support and stability and enabling the possibility of raising it above ground level. The device has been designed for tough environments and demanding outdoor use.
As the generator's weight is 185 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Never less, it can still be moved quite conveniently with the help of a wheel kit and a folding handle, once it is placed on the ground.
Further safety during transport, loading and unloading of the device is provided by a lift hook, which is placed on the top of the generator's frame.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Alert®), which gives you a complete peace of mind when using it.
Besides the features previously mentioned, accessory-wise, the Honda EB4000 comes with the usual documentation and user manual needed to get you promptly started.
Honda’s iAVR (Intelligent Automatic Voltage Regulation) reduces voltage fluctuation by up to 50% over current AVR systems.
In conventional generators, when a load is applied, the engine’s rpm drops, which causes the voltage and frequency to drop as well, until the rpm recovers.
As a result, voltage and frequency are precisely regulated and the EB4000 is able to produce a starting wattage above the maximum rating, for up to 10 seconds. Therefore, thanks to iAVR, the $model is able to “overclock” itself above its 4000 starting watts and provide up to 5000 W.
The Honda EB4000 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.
The Honda EB4000 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Honda EB4000 compare to generators of similar power (between 3000 and 4000 W).
- A weight of 185 lbs makes the Honda EB4000 one of the heavier devices in the 3000-4000 rated wattage range. In terms of weight, one of the champions in their power range is the Generac GP3500iO, standing at just 74.3 lbs.
- With a lowest possible noise of 61 dBA, this generator places itself amongst the more quiet of the products delivering 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.
- As the EB4000 features an autonomy of 16 hours at 50% load, it has a higher run time than an average generator of its power range.
- 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.39 GPH at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.
As you can see from this dynamic chart, when compared to other 3000-4000W generators, the Honda EB4000 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
- iAVR technology
- Quiet for its power (61 dBA)
- High run time
- On the expensive side
- No data center
- No electric start
- On the heavy side (185 lbs)
- Low fuel efficiency
