Description

Zoom on the Honda EM6500SX

In summary, the Honda EM6500SX is a portable generator especially useful for:

  • RV travellers looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events
  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals who want to ensure that a power failure will not prevent them from working

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Honda EM6500SX in use

The Honda EM6500SX

The Honda EM6500SX's design includes a gasoline-fueled 389 cc Honda iGX390 OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 5500W and also a peak wattage of 6500W (and even up to 7000 W thanks to the iAVR technology).

Enjoying a noise rating of 64 dBA (just slightly more noisy than a normal conversation), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a simple and elegant electric starter (battery included). For additional convenience, the EM6500SX may also be remotely started (via the My Generator App).

Thanks to a fuel capacity of 6.2 gallons, the EM6500SX can operate for around 9.8 hours at 50% load with a full tank (fuel consumption around 0.63 GPH).

The quite high THD (<10%) of the EM6500SX makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel features the upcoming 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

It also sports 1 DC outlet: there's a 12V 8A output allowing you to easily charge your batteries.

Even though this Honda generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via 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.

Portability

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 device has been designed for tough 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). 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.

Features

Panel of the Honda EM6500SX

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

Security-wise, this product benefits from an automatic low oil shut-off (Oil Alert®) and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

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.

CO Minder

CO Minder of the Honda EM6500SX

CO Minder monitors the ambient CO concentration

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

Honda My Generator App

Honda My Generator helps you monitor your unit

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.

iAVR Technology

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.

Emissions

The Honda EM6500SX 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, so it is adequate for use in forested areas.

The unit also meets the ANSI/PGMA G300-2018 safety and performance requirements.

Product Video

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).

  • Considering its dry weight of 231.7 pounds, the Honda EM6500SX is one of the heavier generators producing between 5000 and 6000 running watts. 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 you are concerned with noise, check out the Honda EU7000iS, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • Regarding its autonomy, the autonomy of the EM6500SX, reaching around 9.8 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Cat RP5500, as it provides 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. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 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:

Price comparison

As you can see from this interactive chart, when compared to other 5000-6000W generators, the Honda EM6500SX is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
