Zoom on the Genmax GM3300i
In a nutshell, the Genmax GM3300i is a compact and lightweight portable inverter generator mostly geared towards:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in outdoor fairs, festivals or events
- DIYers who wish to improve their efficiency with tools
- 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 buffs looking to enhance their experience
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.
Power & Run Time
The Genmax GM3300i
The Genmax GM3300i's engine, 145 cc (5.2 hp) Dinking OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3,000W and reaches a peak wattage of 3,300W. Moreover, since it is parallel capable (parallel kit (opens in a new tab) not included), its power may be doubled if linked to a second compatible unit.
The inverter generator features a conventional pull-start mechanism. It is rated for a noise of 62 dBA (just slightly more noisy than background music).
The GM3300i can operate for up to 6 hours with a full tank (fuel consumption around 0.17 GPH), due to its fuel capacity of 1 gallon.
Sensitive electronics can be safely plugged in the AC outlets, as the GM3300i produces a clean sine wave, with a <3% Total Harmonic Distortion (THD).
Outlets
The control panel features the upcoming 3 AC outlets:
It also sports 2 DC outlets: there's two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.
With its TT-30R receptacle (TT as in 'Travel Trailer'), this Genmax generator is RV Ready.
Portability
Thanks to its closed inverter generator design (L18.9 x W11.4 x H17.3 in), the Genmax GM3300i, is more esthetical than a typical, open frame generator. This type of design is the most modern and convenient way to recreationally generate power.
Weighing just 47.4 lbs, the GM3300i can be considered a lightweight portable generator. As it can be moved by a single person without much effort, the generator and its power can be enjoyed on-the-go. In addition, a handle (molded in the case) lets you carry it easily and further increases its convenience.
Features
The GM3300i's control panel
Several light indicators serve to show you when the generator is on overload, the generator is ready and its oil levels are insufficient.
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.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Genmax GM3300i also is packed along with the following accessories: tool kit and funnel.
Emissions
The Genmax GM3300i is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor, so it is adequate for use in forested areas.
In addition, the unit meets the ANSI/PGMA G300-2018 safety and performance requirements.
Product Video
The Genmax GM3300i versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Genmax GM3300i compare to inverter generators of similar power (between 2500 and 3500 W).
- Weight-wise, the Genmax GM3300i has only 47.4 lbs, which renders it one of the lighter inverter generators which produce 2500 to 3500 rated watts. Regarding dry weight, one of the champions in the same power range is the Pulsar PGD40iSCO, with a dry weight of only 46 lbs.
- As this inverter generator can emit noise as low as 62 dBA, it finds itself in the average expected noise for this kind of power. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU3000iS with only 50 dBA.
- Autonomy-wise, with up to 6 hours on a full tank at a 25% load, the GM3300i is on the low end when compared to other inverter generators of a similar power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200914, reaching up to 22 hours.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This inverter generator has an estimated fuel consumption of roughly 0.17 GPH (gallon per hour) at a 25% load, rendering it somewhat average compared to devices of a similar output. If fuel consumption is your top priority, we suggest to check out the Energizer eZV3500P, which has a fuel consumption of only 0.13 GPH and thus, is one of the most efficient devices in our database.
Price comparison
As you can see from this interactive chart, when compared to other 2500-3500W inverter generators, the Genmax GM3300i is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
