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
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Food van owners who know that just a short power outage could lose them hundreds of dollars
- 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
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).
Enjoying a noise rating of 64 dBA (just slightly more noisy than background music), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a simple and elegant electric starter (battery included). Moreover, to offer you even more convenience, the EM6500SX can also be remotely started (via the My Generator App).
The fuel capacity of 6.2 gallons allows the EM6500SX to operate for around 9.8 hours at 50% load with a full tank (fuel consumption around 0.63 GPH).
The EM6500SX is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<10%).
The control panel includes the following 6 AC outlets:
It also sports 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, since the EM6500SX bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.
The dimensions of the Honda EM6500SX, which are L41.4 x W27.8 x H28.3 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
As the generator's weight is 231.7 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (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.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
From a security point of view, the generator is equipped with an automatic low oil shut-off (Oil Alert®) and an overload protection (circuit breaker), giving you a peace of mind during use.
Along with the aforementioned features, from an accessory standpoint, the Honda EM6500SX's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly. 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 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, so it is adequate for use 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).
- With its weight of 231.7 lbs, the Honda EM6500SX is one of the heavier generators in the 5000-6000 rated wattage category. If you are concerned by weight, one of the champions in the above-mentioned power range is the Genmax GM6000XiE, with a dry weight of just 106.9 pounds.
- Since this generator is rated for a lowest possible noise of 64 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 Honda EU7000iS with only 52 dBA.
- As for its autonomy, the EM6500SX, with an autonomy of around 9.8 hours at a 50% load, is placed on the low end among the generators of its kind. 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 Predator 6500, 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.63 GPH at a 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the A-iPower SUA7000L, with a fuel consumption of 0.36 GPH could be in your good books.
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
