Zoom on the Honda EM5000SX
In summary, the Honda EM5000SX is a portable generator especially useful for:
- RV travellers looking for even more independence
- 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 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 houses a 389 cc Honda iGX390 OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 4500W along with a peak wattage of 5000W (and even up to 7000 W thanks to the iAVR technology).
At a noise rating of 63 dBA (just slightly more noisy than background music), this generator can be started via a simple traditional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included). For additional convenience, the EM5000SX may 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 provides the upcoming 6 AC outlets:
In addition, it provides 1 DC outlet: there's a 12V 8A output allowing you to easily charge your batteries.
This Honda generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor. 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 Honda EM5000SX has the following dimensions: L41.1 x W27.8 x H28.3 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 226.4 lbs. However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.
Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Alert®).
Accessory-wise, along with the previously mentioned features, the Honda EM5000SX is packaged with the standard documentation and an owner's manual (opens in a new tab), helping you start the device 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 and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.
Moreover, it features a spark arrestor and thus, may be used 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).
- A weight of 226.4 lbs makes the Honda EM5000SX one of the heavier devices in the 4000-5000 rated wattage range. In terms of weight, one of the champions in their power range is the Pulsar PG5250, standing at just 99.5 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 important to you, one of the least noisy generators of this power range is the A-iPower AP5000 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.59 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Pulsar PG5250B, which has a fuel consumption of only 0.33 GPH and thus, is one of the most efficient devices in our database.
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
- On the heavy side (226.4 lbs)
- Low fuel efficiency
