Description

Zoom on the Genmax GM5500XiD

In a nutshell, the Genmax GM5500XiD is a compact and lightweight portable inverter generator mostly geared towards:

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.

Power & Run Time

The Genmax GM5500XiD in use

The Genmax GM5500XiD

Thanks to its dual-fuel technology, the Genmax GM5500XiD provides a 120V output and offers both versatility and power. When utilizing gasoline, it delivers a running wattage of 4,000W and a starting wattage of 5,500W. Alternatively, when operating on propane, it provides 3,600 running watts and 4,950 starting watts. Moreover, the parallel capability (parallel kit not included) enables power output to increase when paired with another similar or compatible unit, providing increased energy capacity and versatility for a wide range of needs.

With a noise rating of 68 dBA (less noisy than an office), the inverter generator features a traditional recoil pull-start mechanism.

In terms of its run time capability, the GM5500XiD, furnished with a 2.2 gallons fuel tank, can maintain operations for up to 11 hours on a full tank of gasoline (with fuel consumption averaging 0.2 gallons per hour). It also provides up to 17.5 hours (estimation based on a 20 lbs tank - propane consumption around 0.27 GPH) of operation with propane.

With a <3% Total Harmonic Distortion (THD), the GM5500XiD delivers a clean sine wave, essential for safeguarding your delicate electronics when plugged into its AC outlets.

Outlets

The control panel features 3 AC outlets as follows:

Duplex 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

It also sports 2 DC outlets: there's two 5V USB ports (1 x USB-A and 1 x USB-C) ideal for charging various electronic devices such as smartphones and tablets.

Equipped with a TT-30R receptacle (TT representing 'Travel Trailer'), this Genmax generator is RV Ready, ensuring compatibility with recreational vehicles.

Portability

With dimensions of L23.1 x W18.5 x H17.8 in, the standard open frame design of the Genmax GM5500XiD provides stability and easy maintenance access to components, as well as good air circulation. The design is ideal for rough environments and demanding outdoor use.

The GM5500XiD's dry weight of 68 lbs lets you use its power anywhere needed. Furthermore, thanks to its set of wheels and its folding handle, shifting the generator once it's placed is a breeze.

Features

The GM5500XiD's control panel

To facilitate status and activity monitoring, a convenient meter, offering voltage, frequency, and lifetime hours readings are embedded in the control panel of the GM5500XiD.

In addition to this info, several light indicators serve to show you when the generator is ready, the generator is on overload and the oil level is too low.

Featuring a built-in fuel gauge, the inverter generator offers quick, convenient, and easy gas level checks at a glance.

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.

In addition to the traditional documentation and an owner's manual (opens in a new tab) to help you get started promptly, the Genmax GM5500XiD also includes several accessories: propane hose, tool kit, funnel and oil.

The Genmax GM5500XiD versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM5500XiD compare to inverter generators of similar power (between 3500 and 4500 W).

  • Weight-wise, the Genmax GM5500XiD has only 68 lbs, which renders it one of the lighter inverter generators which produce 3500 to 4500 rated watts. If weight is a key factor for your needs, the WEN 56432iX is noteworthy for being one of the top contenders in this power range, with a dry weight of 52.9 pounds.
  • This inverter generator, with its lowest possible noise rated at 68 dBA falls into the more noisy category, compared to other devices of a similar running wattage. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen5000DF with only 52 dBA.
  • As for its autonomy, the GM5500XiD, with an autonomy of up to 11 hours at a 25% load, is placed on the low end among the generators of its kind. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 200977, as it provides up to 22 hours.
  • While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. This inverter generator has an estimated fuel consumption of roughly 0.2 GPH (gallon per hour) at a 25% load, rendering it somewhat average compared to devices of a similar output. If minimizing fuel usage is one of your key priorities, the Champion 201319 is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.16 gallons per hour.

Price comparison

As you can see from these interactive charts, when compared to other 3500-4500W dual fuel inverter generators, the Genmax GM5500XiD 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.
