Zoom on the Honda EM5000SX
In a nutshell, the Honda EM5000SX is a portable generator mostly geared towards:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners in need of an emergency backup power for their essentials
- Professionals who want to be able to deliver results, even during a power failure
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 EM5000SX's design includes a gasoline-fueled 389 cc Honda iGX390 OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 4,500W and also a peak wattage of 5,000W (and even up to 7,000 W thanks to the iAVR technology).
The generator is rated for a noise of 63 dBA (just slightly more noisy than an office). Its starting mechanisms include a conventional pull-start mechanism and a simple and elegant electric starter (battery included). To add further convenience, the EM5000SX can be remotely started (via the My Generator App).
With a full tank, the EM5000SX can operate for around 10.5 hours at 50% load (fuel consumption around 0.59 GPH), thanks to its fuel capacity of 6.2 gallons.
As the EM5000SX has a relatively high THD (<10%), it is not recommended to use it to power sensitive electronic devices.
The control panel features the following 6 AC outlets:
In addition, it provides 1 DC outlet: there's a 12V 8A output with which you may charge your batteries with ease.
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, due to the featured twist-lock L14-30R receptacle, the EM5000SX is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.
The design of the Honda EM5000SX is a typical, open frame, with the dimensions of L41.1 x W27.8 x H28.3 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough environments and demanding 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. However, this lack of maneuverability is compensated by its wheel kit and its folding handle, with which you can conveniently shift it, once it's on the ground.
Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Alert®), letting you use it with a peace of mind.
As for its accessories, apart from the previously mentioned features, the Honda EM5000SX also comes with the basic documentation and an owner's manual (opens in a new tab), allowing you to start it right away. 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 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 therefore, can 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).
- Considering its dry weight of 226.4 pounds, the Honda EM5000SX is one of the heavier generators producing between 4000 and 5000 running watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PG5250, with a dry weight of just 99.5 pounds.
- As its lowest possible noise is rated at 63 dBA, this generator qualifies as one of the more quiet of the products of similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Yamaha EF4500iSE with only 58 dBA.
- The EM5000SX, falls within the average autonomy range compared to generators of a roughly same power, with a run time of around 10.5 hours at a 50% load and a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Dewalt DXGN4500, boasting with around 15 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.59 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Pulsar PG5250B. With a fuel consumption of as little as 0.33 GPH, it is one of the most efficient generators currently on the market.
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
