Zoom on the Genmax GM7250iEDC

In a few words, the Genmax GM7250iEDC is a portable inverter generator perfectly suited for:

  • RV travellers who wish to upgrade their experience to another level
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go
  • Professionals in need of safely powering high-intensity work or lighting equipment

Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.

Power & Run Time

With its dual-fuel technology, the Genmax GM7250iEDC delivers 120/240V, and offers power and flexibility. Running on gasoline, it boasts a running wattage of 6,000W and a peak wattage of 7,250W. When powered by propane, it delivers 5,500 running watts and 6,500 peak watts. Moreover, the parallel capability (GM9000PK parallel cable (opens in a new tab) 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.

Enjoying a noise rating of 63 dBA (just slightly more noisy than an office), this inverter generator offers the versatility of starting with either a manual recoil starter system or a convenient and easy-to-use electric starter (battery included). For added user convenience, the GM7250iEDC is equipped with remote starting capabilities (key fob included).

As for its running time, the GM7250iEDC, along with its 3.6 gallons fuel capacity, can run for up to 10 hours with a full tank filled with gasoline (fuel consumption around 0.36 GPH). If propane is used, it can operate for up to 9 hours (estimation based on a 20 lbs tank - propane consumption around 0.52 GPH).

The GM7250iEDC generates a clean sine wave with <5% Total Harmonic Distortion (THD), ensuring minimal electrical noise and fluctuations. This feature makes it ideal for powering sensitive electronics, providing stable and reliable AC power through the outlets.


The control panel is equipped with the following 3 AC outlets:

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

Furthermore, it showcases 2 DC outlets: there's two 5V USB ports (1 x USB-A and 1 x USB-C) providing convenient charging capabilities for mobile phones, tablets, and other electronic devices.

If your RV requires a 50-amp service, consider this Genmax unit RV-ready, as it includes a 14-50R outlet. In addition, the unit features an ATS plug, which makes it compatible with automatic transfer switches.


As an inverter generator, the Genmax GM7250iEDC showcases a closed design (L24.2 x W19.5 x H21.9 in), enhancing aesthetics and ensuring quieter operation compared to conventional, open frame models. The featured design follows the latest trends and is ideal for easy and recreational use.

As the generator's weight is 144.6 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, the limited maneuverability is remedied with its set of 2 wheels and its telecospic handle, facilitating convenient shifting once the generator is positioned on the ground.

The GM7250iEDC's control panel

Enhancing monitoring capabilities, the GM7250iEDC features a digital data center within its control panel, furnishing essential details on the voltage, power output, lifetime run hours and fuel level for tracking activity and status.

From a security standpoint, the generator is furnished with an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during operation.

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 GM7250iEDC also is packed along with the following accessories: tool kit, funnel, key fob and propane hose.

The Genmax GM7250iEDC versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM7250iEDC compare to generators of similar power (between 5500 and 6500 W).

  • Regarding weight, the Genmax GM7250iEDC comes in at only 144.6 pounds, positioning itself as one of the lighter options among generators spanning from 5500 to 6500 in rated wattage. If weight is an important consideration for you, the Pulsar PGDA70BiSCO stands out as one of the top contenders in this power category, with a dry weight of 118 pounds.
  • This inverter generator offers a rated noise level of 63 dBA, placing it among the quieter alternatives in its power category. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU7000iS with only 52 dBA.
  • As far as autonomy is concerned, providing up to 10 hours of runtime with a full tank at a 25% load, the GM7250iEDC falls into the low end in comparison with other devices of a comparable power output. For those prioritizing autonomy, the DuroMax XP7500DX could be considered, as it offers one of the longest run times among generators with similar power output, reaching up to 18 hours.
  • Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. With a fuel usage of about 0.36 GPH at a 25% load, this inverter generator falls within the typical gasoline consumption range observed in comparably powerful products. If you wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the DuroMax XP7000iH, which has an impressively low fuel consumption of 0.19 GPH.

Price comparison

As you can see from these interactive charts, when compared to other 5500-6500W generators, the Genmax GM7250iEDC is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
