Description

Zoom on the Genmax GM5500i

In a few words, the Genmax GM5500i is a compact portable inverter generator perfectly suited for:

  • RV travellers looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events

  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Camping and tailgating hobbyists looking for a portable power source
  • Professionals in need of safely powering high-intensity work or lighting equipment

In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.

Power & Run Time

The Genmax GM5500i in use

The Genmax GM5500i

Featuring a 312 cc Dinking OHV 4-stroke engine, the Genmax GM5500i operates using gasoline, providing 120/240V, with a running wattage of 5,000W and a starting wattage of 5,500W.

The inverter generator, rated for a noise of 62 dBA (just slightly more noisy than a normal conversation), provides flexibility in starting, offering both a simple traditional pull-start mechanism and a straightforward and intuitive electric starter (battery included).

The GM5500i boasts a fuel tank capable of holding 3.5 gallons, allowing it to run continuously for up to 13 hours (with fuel usage averaging around 0.27 gallons per hour).

As the GM5500i produces a clean sine wave, with a <3% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the 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 offers 2 DC outlets: there's two 5V USB ports (USB-A) ensuring convenient charging of devices like mobile phones and tablets, for connectivity on the go.

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

With its enclosed inverter generator design (L21.1 x W18.5 x H24 in), the Genmax GM5500i offers superior aesthetics and operates with minimized noise levels, distinguishing itself from standard, open frame generators. The design follows the contemporary trends and is perfect for recreationally generating power.

Since the generator weighs 116.6 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). Nevertheless, the restricted maneuverability is counteracted by its set of 2 wheels (⌀5.5") and its telecospic handle, enabling easy shifting once the generator is set in place.

Features

Panel of the Genmax GM5500i

The GM5500i's control panel

Included in the control panel of the GM5500i, a digital data center assists in tracking its status and activity by providing details on the frequency, fuel level, lifetime run hours, power output and voltage.

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

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

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.

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 inverter generators of similar power (between 4500 and 5500 W).

  • Considering its weight, the Genmax GM5500i registers at a modest 116.6 pounds, placing it among the lighter inverter generators in the 4500 to 5500 rated wattage selection. Weight-conscious users may find the WEN DF680iX appealing, as it is one of the top contenders in this power range, weighing just 94.8 pounds.
  • Delivering a rated noise output as low as 62 dBA, this inverter generator is has a quieter operation that most units of similar type and 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.
  • Regarding its runtime, the GM5500i operates for up to 13 hours at a 25% load, positioning it at the lower spectrum among comparable inverters. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 201532, reaching up to 18 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. With an estimated gasoline consumption of 0.27 GPH (gallon per hour) at 25% load, this inverter generator is among the more fuel-efficient of the products in the above-mentioned wattage range. If you wish to further improve in the area of fuel efficiency, the DuroMax XP7000iH, which boasts with a gas consumption of only 0.19 GPH, may be the right generator for you.

Price comparison

As you can see from these interactive charts, 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.
