Zoom on the Honda EM6500SX
In summary, the Honda EM6500SX 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
- Food truck owners who do not wish to see their business interrupted under any circumstances
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals in need of safely powering high-intensity work or lighting equipment
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 EM6500SX houses a 389 cc Honda iGX390 OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 5,500W along with a peak wattage of 6,500W (and even up to 7,000 W thanks to the iAVR technology).
The generator is rated for a noise of 64 dBA (just slightly more noisy than an office). Its starting mechanisms include a conventional pull-start mechanism and a convenient and easy-to-use electric starter (battery included). The EM6500SX can also be remotely started, offering further convenience (via the My Generator App).
The EM6500SX can operate for around 9.8 hours at 50% load with a full tank (fuel consumption around 0.63 GPH), due to its fuel capacity of 6.2 gallons.
The powering of sensitive electronic devices with the EM6500SX is not recommended 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.
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 EM6500SX 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 EM6500SX has a conventional, open frame design, of the following dimensions: L41.4 x W27.8 x H28.3 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.
Since the generator weighs 231.7 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). 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.
Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Alert®), which gives you a complete peace of mind when using it.
Besides the features previously mentioned, accessory-wise, the Honda EM6500SX 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 EM6500SX 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 EM6500SX 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 EM6500SX is able to produce a starting wattage above the maximum rating, for up to 10 seconds. Therefore, thanks to iAVR, the EM6500SX is able to “overclock” itself above its 6500 starting watts and provide up to 7000 W.
The Honda EM6500SX is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor, making it usable in forested areas.
In addition, the unit meets the ANSI/PGMA G300-2018 safety and performance requirements.
The Honda EM6500SX versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Honda EM6500SX compare to generators of similar power (between 5000 and 6000 W).
- A weight of 231.7 lbs makes the Honda EM6500SX one of the heavier devices in the 5000-6000 rated wattage range. If weight matters to you, one of the champions in this power range is the Genmax GM6000XiE with only 106.9 pounds.
- With a lowest noise rating of 64 dBA, the generator is one of the more quiet of the generators of similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU7000iS with only 52 dBA.
- As far as autonomy is concerned, providing around 9.8 hours of runtime with a full tank at a 50% load, the EM6500SX falls into the low end in comparison with other devices of a comparable power output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Predator 6500, boasting with around 14.5 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 not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.63 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the A-iPower SUA7000L, which boasts with a gas consumption of only 0.36 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 5000-6000W generators, the Honda EM6500SX 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

- CO Minder
- Mobile app
- iAVR technology
- Quiet for its power (64 dBA)
- On the expensive side
- Not CARB-compliant
- On the heavy side (231.7 lbs)
- Relatively low run time
- Low fuel efficiency
