Description

Zoom on the Honda EM5000SX

In a nutshell, the Honda EM5000SX is a portable generator mostly geared towards:

  • RV travellers looking for even more independence
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • 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

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 EM5000SX in use

The Honda EM5000SX

The Honda EM5000SX'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 4500W and also a peak wattage of 5000W.

With a noise rating of 63 dBA (just slightly more noisy than an office), the generator features a simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included). Moreover, to offer you even more convenience, the EM5000SX can also be remotely started (separate purchase).

Thanks to a fuel capacity of 6.2 gallons, the EM5000SX can operate for around 11.2 hours at 50% load with a full tank (fuel consumption around 0.55 GPH).

Outlets

The control panel provides the upcoming 6 AC outlets:

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

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

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, as the EM5000SX 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.

Portability

The dimensions of the Honda EM5000SX, which are L41.1 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. The featured design is ideal for the outdoors and all tough environments.

As the generator's weight is 232 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (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 EM5000SX

The EM5000SX's control panel

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a 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.

Regarding its accessories, besides the aforementioned features, the Honda EM5000SX's box includes the typical documentation and an owner's manual (opens in a new tab), letting you start it right off the bat.

Emissions

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, so it is adequate for use 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).

  • Considering its dry weight of 232 pounds, the Honda EM5000SX is one of the heavier generators producing between 4000 and 5000 running watts. If weight matters to you, one of the champions in this power range is the Pulsar PG5250 with only 99.5 pounds.
  • With a lowest possible noise of 63 dBA, this generator places itself amongst the more quiet of the products delivering similar power. For those who are looking for a less noisy device, we suggest the Yamaha EF4500iSE. With just 58 dBA, it is one of the most quiet devices in this power range.
  • The EM5000SX, offering a run time of around 11.2 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. 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 Dewalt DXGN4500, with around 15 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.55 GPH. If fuel consumption is your top priority, we suggest to check out the Pulsar PG5250B, which has a fuel consumption of only 0.33 GPH and thus, is one of the most efficient devices in our database.

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

Price comparison

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

STRENGTHS:
  • GFCI Outlets
  • Remote start capable
  • Quiet for its power (63 dBA)
AVERAGE SPECS:
  • Decent run time
WEAKNESSES:
  • On the expensive side
  • No data center
  • On the heavy side (232 lbs)
