Description

Zoom on the Honda EM6500SX

In a nutshell, the Honda EM6500SX is a portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • 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.

Power & Run Time

The Honda EM6500SX in use

The Honda EM6500SX

Running on gasoline, the Honda EM6500SX operates with a 389 cc Honda iGX390 OHV 4-stroke engine, delivering 120/240V, with a running wattage of 5,500W and a peak wattage of 6,500W (and even up to 7,000 W thanks to the iAVR technology).

The generator, rated for a noise of 64 dBA (just slightly more noisy than background music), provides flexibility in starting, offering both a traditional recoil pull-start mechanism and an intuitive and practical electric starter (battery included). For added user convenience, the EM6500SX is equipped with remote starting capabilities (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).

Given the EM6500SX's relatively high Total Harmonic Distortion (THD) of less than 10%, it is advisable to avoid using it to power sensitive electronic devices.

Outlets

The control panel features the following 6 AC outlets:

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

Furthermore, it showcases 1 DC outlet: there's a 12V 8A output with which you may charge your batteries with ease.

Despite not meeting the 'RV Ready' criteria, this Honda generator grants the advantage of simple RV compatibility via its L5-30R receptacle, enabling you to conveniently power your RV by using 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

At L41.4 x W27.8 x H28.3 in, the standard open frame design of the Honda EM6500SX delivers stability alongside easy maintenance access to components and good air cooling. The featured design is ideal for the outdoors and all tough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 231.7 pounds. Nonetheless, the limited maneuverability is compensated for by utilizing its wheel kit and its folding handle, which facilitates shifting once the generator is set on the ground.

The built-in fuel gauge of the generator ensures simple and quick gas level assessments.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off (Oil Alert®), letting you use it with a peace of mind.

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.

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.

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.

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 a weight of 231.7 lbs, the Honda EM6500SX is notably on the heavier side among generators in the 5000-6000 rated wattage range. If weight matters to you, one of the champions in this power range is the Champion 201238 with only 101.4 pounds.
  • With noise levels starting from 64 dBA rating, this generator stands out as one of the quieter options among products of similar power. For those who are looking for a less noisy device, we suggest the Honda EU7000iS. With just 52 dBA, it is one of the most quiet devices in this power range.
  • Concerning its runtime, the EM6500SX provides around 9.8 hours at a 50% load, indicating that it falls on the lower side compared to other generators of its power range. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Predator 6500, which is able to run for 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're placing a high priority on fuel consumption, the A-iPower SUA7000L, with a low fuel consumption rate of 0.36 GPH, could be an option to consider.

Here's a list of the most popular specific comparisons:

Price comparison

As you can see from these interactive charts, 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

STRENGTHS:
  • GFCI Outlets
