Zoom on the Honda EM5000SX
In summary, the Honda EM5000SX is a portable generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in outdoor fairs, festivals or events
- 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 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).
The generator is rated for a noise of 63 dBA (just slightly more noisy than a normal conversation). 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).
Thanks to a fuel capacity of 6.2 gallons, the EM5000SX can operate for around 10.5 hours at 50% load with a full tank (fuel consumption around 0.59 GPH).
The EM5000SX is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<10%).
The control panel features the following 6 AC outlets:
Furthermore, it has 1 DC outlet: there's a 12V 8A output with which you may charge your batteries with ease.
While this Honda generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with 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 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 featured design is ideal for the outdoors and all tough environments.
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. 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.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
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.
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. Therefore, its sale and purchase are permitted in all of the 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).
- As its dry weight is 226.4 pounds, the Honda EM5000SX is one of the heavier of the products which can generate 4000 to 5000 running watts. Regarding dry weight, one of the champions in the same power range is the Powerhorse LC4500i, with a dry weight of only 99 lbs.
- With a lowest possible noise of 63 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 Powerhorse LC4500i, whose lowest noise levels reach just 57 dBA.
- Offering around 10.5 hours of running time on a full tank at 50% load, the EM5000SX is within the average autonomy range of similarly powerful generators. 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.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.59 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the Pulsar PG5250B, which boasts with a gas consumption of only 0.33 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
- On the heavy side (226.4 lbs)
- Low fuel efficiency
