Description

Zoom on the Genmax GM5500i

In summary, the Genmax GM5500i is a compact portable inverter generator especially useful for:

  • 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 in need of an emergency backup power for their essentials
  • Camping and tailgating buffs looking to enhance their experience
  • Professionals in need of safely powering high-intensity work or lighting equipment

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Genmax GM5500i in use

The Genmax GM5500i

The Genmax GM5500i's core is the 312 cc Dinking OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 5000W and a peak wattage of 5500W.

The inverter generator features a simple traditional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 62 dBA (just slightly more noisy than an office).

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

The GM5500i generates a clean sine wave: providing <5% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel features the upcoming 5 AC outlets:

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

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

As it features a twist-lock L14-30R receptacle, the GM5500i is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The Genmax GM5500i is an inverter generator and has an encased design of the following dimensions: L21.1 x W18.5 x H24 in. Thus, it is more aesthetical than conventional, open frame products. The generator has a contemporary design, convenient for recreationally generating power.

As the generator's weight is 116.6 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, its challenging mobility is solved by its set of 2 wheels (⌀5.5") and its telecospic handle, which will ease its displacement, once it is on the floor.

Features

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 fuel level, frequency, power output, voltage and lifetime run hours.

In addition to this info, some light indicators allow you to instantly see if the generator is ready, the generator is overloaded and the oil level is too low.

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

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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Genmax GM5500i, the following accessories are also included: 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, making it usable in forested areas.

In addition, the unit meets the ANSI/PGMA G300-2018 safety and performance requirements.

Product Videos

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 for its weight, the Genmax GM5500i weighs only 116.6 pounds, making it one of the lighter generators in the 4500-5500 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.
  • At a lowest noise rating of 62 dBA, this inverter generator is one of the quieter devices 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 GM5500i, reaching up to 13 hours at a 25% load, can be considered as low end, compared to other products of a roughly equal output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Westinghouse WGen5500, which is able to run for up to 20 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This inverter generator, with an estimated fuel consumption of just 0.27 GPH (gallon per hour) at 25% load, is one of the most fuel efficient generators, for the previously mentioned wattage range.

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.
