Zoom on the Honda EM5000SX
In summary, the Honda EM5000SX is a portable generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- Occasional participants of outdoor events, competitions, concerts and festivals
- 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
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 engine, 389 cc Honda iGX390 OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 4500W and reaches a peak wattage of 5000W.
The generator is rated for a noise of 63 dBA (just slightly more noisy than background music). Its starting mechanisms include a conventional pull-start mechanism and a convenient and easy-to-use electric starter (battery included). Moreover, to offer you even more convenience, the EM5000SX can also be remotely started (separate purchase).
With a full tank, the EM5000SX can operate for around 11.2 hours at 50% load (fuel consumption around 0.55 GPH), thanks to its fuel capacity of 6.2 gallons.
The control panel features the following 6 AC outlets:
Additionally, it features 1 DC outlet: there's a 12V 8A output allowing you to easily charge your batteries.
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. Besides, because the EM5000SX is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
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 device has been designed for tough environments and demanding outdoor use.
Since the generator weighs 232 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.
Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.
From a security standpoint, the product offers an automatic low oil shut-off (Oil Alert®) and an overload protection (circuit breaker), allowing you to use it with a peace of mind.
Regarding its accessories, besides the aforementioned features, the Honda EM5000SX's box includes the typical documentation and an owner's manual (opens in a new tab), letting you start it right off the bat.
CO Minder (new model)
Note: The CO Minder is a new feature introduced in 2020 that is not yet present in all EM5000SX units. Make sure to select the "With CO Minder" tab above our retailers list if you wish to benefit from this feature.
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 (new model)
The Honda My Generator App (available on iOS and Android) makes owning the EM5000SX (new version, with CO-Minder) 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.
The Honda EM5000SX 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, making it usable in forested areas.
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).
- As its dry weight is 232 pounds, the Honda EM5000SX is one of the heavier of the products which can generate 4000 to 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.
- As the EM5000SX features an autonomy of around 11.2 hours at 50% load, it has a higher run time than an average generator of its power range. 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.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.55 GPH at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.33 GPH, the Pulsar PG5250B is a device you should look out for.
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 capable
- CO Minder (according to model)
- Mobile app (according to model)
- Quiet for its power (63 dBA)
- High run time
- On the expensive side
- On the heavy side (232 lbs)
- Low fuel efficiency
