Description

Zoom on the Genmax GM10500XiT

In a few words, the Genmax GM10500XiT is a powerful portable inverter generator perfectly suited for:

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • RV travellers wishing to enhance their freedom and nomad lifestyle

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

Power & Run Time

The Genmax GM10500XiT in use

The Genmax GM10500XiT

The Genmax GM10500XiT delivers 120/240V and benefits from a tri-fuel technology that allows it to run on gasoline, propane, or natural gas. When gasoline-powered, it enjoys a running wattage of 7,800W and a peak wattage of 10,500W. When propane-powered, it benefits from 7,000 rated watts and 9,500 peak watts. Its natural gas operation offers 6,250W of rated wattage and 8,500W of starting wattage. In addition, the parallel capability (parallel kit not included) empowers increasing of power output when linked to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.

The inverter generator, rated for a noise of 74 dBA (just slightly more noisy than a vacuum cleaner), provides flexibility in starting, offering both a traditional recoil pull-start mechanism and a convenient and efficient electric starter (battery included). Additionally, the GM10500XiT features remote starting, offering users increased convenience (key fob included).

Regarding its running time, the GM10500XiT, with a 5.8 gallons fuel capacity, can operate for up to 13.5 hours with a full tank of gasoline (fuel consumption around 0.43 GPH). When using propane, it can run for up to 8 hours (estimation based on a 20 lbs tank - propane consumption around 0.59 GPH).

Sensitive electronics can be safely plugged in the AC outlets, as the GM10500XiT produces a clean sine wave, with a <3% Total Harmonic Distortion (THD).

Outlets

The control panel features the upcoming 4 AC outlets:

Duplex 120V 20A (5-20R)
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

Additionally, it features 3 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle with which you may charge your batteries with ease and two 5V USB ports (1 x USB-A and 1 x USB-C) allowing you to conveniently charge electronics such as mobile phones and tablets.

If you own an RV with a 50-amp service, you can consider this Genmax unit as RV-ready, as it features a 14-50R outlet. In addition, due to the featured twist-lock L14-30R receptacle, the GM10500XiT is transfer switch ready: you may connect it to a breaker box to power your household during a power outage. The unit also features an ATS plug, which makes it compatible with automatic transfer switches.

Portability

With dimensions of L25.2 x W19.8 x H21.3 in, the traditional open frame design of the Genmax GM10500XiT ensures stability while allowing easy maintenance access to components and promoting effective air cooling. The generator is designed for outdoor use and demanding environments.

While weighing 123.5 lbs, the generator is classified as 'portable,' indicating its mobility, albeit its heftiness may limit portability in specific situations. However, its challenging mobility is solved by its set of wheels and its folding handle, which will ease its displacement, once it is on the floor.

Features

The GM10500XiT's control panel

Designed with a digital data center, the control panel of the GM10500XiT grants you access to crucial data on the voltage, power output, lifetime run hours and frequency, ensuring practical monitoring of its status and activity.

In addition to this info, the device’s light indicators will display if the generator is ready, the generator is on overload and the oil level is too low.

Equipped with a built-in fuel gauge, the inverter generator facilitates swift gas level checks.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to 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.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Genmax GM10500XiT, the following accessories are also included: cover, neutral bonding plug, natural gas hose with NPT adapter, propane hose, funnel, key fob and tool kit.

The Genmax GM10500XiT versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM10500XiT compare to multi-fuel generators of similar power (between 7500 and 8500 W).

  • Regarding weight, the Genmax GM10500XiT comes in at only 123.5 pounds, positioning itself as one of the lightest option among multi-fuel generators spanning from 7500 to 8500 in rated wattage.
  • This inverter generator has a somewhat average expected noise for its type and power range, rated at 74 dBA. If you are concerned with noise, check out the DuroMax XP9500iH, which is one of the least noisy generators in its power range, with a noise rating of just 61 dBA.
  • As for its runtime, the GM10500XiT runs for up to 13.5 hours at a 25% load, placing it towards the low end among comparable multi-fuel products. If runtime is a priority for you, the DuroMax XP10000EH stands out as one of the generators with the longest run time in its power range, providing up to 22 hours of continuous use.
  • While run time matters, it's heavily influenced by the fuel tank's capacity. Hence, it's important to consider fuel efficiency alongside. The inverter generator utilizes approximately 0.43 GPH of gasoline at a 25% load, placing it within the typical range of fuel consumption seen in products of comparable wattage. If fuel consumption is your top priority, we suggest to check out the DuroMax XP9500iH, which has a fuel consumption of only 0.34 GPH and thus, is one of the most efficient devices in our database.
