Zoom on the Honda EM5000SX
In a nutshell, the Honda EM5000SX is a portable generator mostly geared towards:
- RV travellers who wish to upgrade their experience to another level
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals who want to be able to deliver results, even during a power failure
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 EM5000SX is powered by a 389 cc Honda iGX390 OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 4,500W as well as a peak wattage of 5,000W (and even up to 7,000 W thanks to the iAVR technology).
The generator features a simple traditional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 63 dBA (just slightly more noisy than a normal conversation). Moreover, to offer you even more convenience, the EM5000SX can also be remotely started (via the My Generator App).
The fuel capacity of 6.2 gallons allows the EM5000SX to operate for around 10.5 hours at 50% load with a full tank (fuel consumption around 0.59 GPH).
The powering of sensitive electronic devices with the EM5000SX is not recommended due to its relatively high THD (<10%).
The control panel features the upcoming 6 AC outlets:
Additionally, it features 1 DC outlet: there's a 12V 8A output with which charging your batteries is made easy.
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. Besides, as the EM5000SX holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.
The Honda EM5000SX has a conventional, open frame design, of the following dimensions: L41.1 x W27.8 x H28.3 in, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 226.4 pounds. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
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 EM5000SX 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.
Honda My Generator App
The Honda My Generator App (available on iOS and Android) makes owning the EM5000SX even more flexible and convenient, whether you are depending on it at home during a power outage, or enjoying an adventure at a remote campsite.
The app connects your unit and your phone via Bluetooth, across a 75-foot line of sight, giving you valuable information about your generator's operation and many additional features in the palm of your hands.
With it, you can easily monitor a range of information such as output power, lifetime run hours, oil life, or estimated remaining runtime. You’ll also receive warnings and notifications to remind you of routine maintenance.
Even better, the app allows you to control multiple, compatible Honda generators from a single mobile device, and to remotely start and stop the EM5000SX without a key fob.
Honda’s iAVR (opens in a new tab) (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.
iAVR is a combination of the DAVR (opens in a new tab) technology and the iGX (opens in a new tab) engine technology, which serves to provide advanced and instantaneous engine rpm control when a load is applied.
As a result, voltage and frequency are precisely regulated and the EM5000SX is able to produce a starting wattage above the maximum rating, for up to 10 seconds. Therefore, thanks to iAVR, the EM5000SX is able to “overclock” itself above its 5000 starting watts and provide up to 7000 W.
The Honda EM5000SX is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor and thus, may be used in forested areas.
In addition, the unit meets the ANSI/PGMA G300-2018 safety and performance requirements.
The Honda EM5000SX versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Honda EM5000SX compare to generators of similar power (between 4000 and 5000 W).
- With its weight of 226.4 lbs, the Honda EM5000SX is one of the heavier generators in the 4000-5000 rated wattage category. Regarding dry weight, one of the champions in the same power range is the WEN 56477i, with a dry weight of only 72.7 lbs.
- Since this generator is rated for a lowest possible noise of 63 dBA, it can be considered as one of the more quiet of the products generating similar power. If noise emissions are one of your priorities, you may be interested in the Yamaha EF4500iSE, one of the least noisy generators similarly powerful as this one, rated for 58 dBA.
- The EM5000SX, offering a run time of around 10.5 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Dewalt DXGN4500, with around 15 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. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.59 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the WEN 56480iX, which boasts with a gas consumption of only 0.27 GPH, may be the right generator for you.
Here's a list of the most popular specific comparisons:
As you can see from this interactive chart, when compared to other 4000-5000W generators, the Honda EM5000SX 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
- GFCI Outlets
- Remote start
- CO Minder
- Mobile app
- iAVR technology
- Quiet for its power (63 dBA)
- Decent run time
- On the expensive side
- Not CARB-compliant
- On the heavy side (226.4 lbs)
- Low fuel efficiency
