Description

Zoom on the Genmax GM5500i

In a nutshell, the Genmax GM5500i is a compact portable inverter generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • 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 who want to be able to use the most necessary devices in their household, even during a blackout
  • Camping and tailgating buffs looking to enhance their experience
  • Professionals who want to be able to deliver results, even during a power failure

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 Genmax GM5500i in use

The Genmax GM5500i

The Genmax GM5500i's design includes a gasoline-fueled 312 cc Dinking OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 5,000W and also a peak wattage of 5,500W.

The inverter generator is rated for a noise of 62 dBA (just slightly more noisy than a normal conversation). Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery included).

The GM5500i can operate for up to 13 hours with a full tank (fuel consumption around 0.27 GPH), due to its fuel capacity of 3.5 gallons.

The GM5500i produces a clean sine wave: thanks to a <3% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel features the upcoming 5 AC outlets:

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

It also sports 2 DC outlets: there's two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.

Due to the featured twist-lock L14-30R receptacle, the GM5500i is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

Thanks to its closed inverter generator design (L21.1 x W18.5 x H24 in), the Genmax GM5500i, is more esthetical than a typical, open frame generator. This type of design is the most modern and convenient way to recreationally generate power.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 116.6 lbs make it incredibly difficult to manually lift and transport. However, this lack of maneuverability is compensated by its set of 2 wheels (⌀5.5") and its telecospic handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Genmax GM5500i

The GM5500i's control panel

To help you monitor the GM5500i's status and activity, its control panel is equipped with a digital data center, giving you information on the lifetime run hours, voltage, power output, fuel level and frequency.

In addition to this info, the device’s light indicators will display if the generator is on overload, the generator is ready and its oil levels are insufficient.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

It also benefits from Genmax's CO DETECT technology, which is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Genmax GM5500i also is packed along with the following accessories: tool kit and funnel.

Emissions

The Genmax GM5500i 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 Genmax GM5500i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM5500i compare to generators of similar power (between 4500 and 5500 W).

  • As far as its dry weight is concerned, the Genmax GM5500i weighs just 116.6 pounds and thus, it is one of the lighter 4500 to 5500 rated wattage generators. If weight is your top priority, one of the champions in this power category is the WEN GN5600, weighing just 103.6 pounds.
  • As its lowest possible noise is rated at 62 dBA, this inverter generator qualifies as one of the more quiet of the products of similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU7000iS, whose lowest noise levels reach just 52 dBA.
  • Autonomy-wise, with up to 13 hours on a full tank at a 25% load, the GM5500i is on the low end when compared to other generators of a similar power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the DuroMax XP5500EH, as it provides up to 19 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. Standing at an estimated 0.27 GPH (gallon per hour) at a 25% load, this inverter generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If fuel consumption is your top priority, we suggest to check out the DuroMax XP5500EH, which has a fuel consumption of only 0.21 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, when compared to other 4500-5500W inverter generators, the Genmax GM5500i is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
