Zoom on the Genmax GM3300i
In short, the Genmax GM3300i is a compact and lightweight portable inverter generator adequately designed for:
- 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 able to use the most necessary devices in their household, even during a blackout

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 GM3300i
Featuring a 145 cc (5.2 hp) Dinking OHV 4-stroke engine, the Genmax GM3300i operates using gasoline, providing 120V, with a running wattage of 3,000W and a starting wattage of 3,300W. Additionally, as the generator is parallel capable (parallel kit (opens in a new tab) not included), it can be linked to a second unit for more power.
Operating at a noise rating of 62 dBA (just slightly more noisy than a normal conversation), this inverter generator starts up with a manual recoil starter system.
The GM3300i's fuel tank holds 1 gallon, ensuring uninterrupted operation for up to 6 hours with a full tank (fuel consumption approximately 0.17 GPH).
Featuring a <3% Total Harmonic Distortion (THD), the GM3300i delivers a clean sine wave, guaranteeing the safety of your sensitive electronics plugged into its AC outlets.
Outlets
The control panel includes the following 3 AC outlets:
It also sports 2 DC outlets: there's two 5V USB ports (USB-A) enabling convenient charging of devices like mobile phones and tablets.
The inclusion of a TT-30R receptacle (TT for 'Travel Trailer') makes this Genmax generator RV Ready, ideal for providing power to recreational vehicles.
Portability
As an inverter generator, the Genmax GM3300i showcases a closed design (L18.9 x W11.4 x H17.3 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.
Since the GM3300i weighs only 47.4 lbs, it can be labeled as a portable lightweight generator. A single person should have no trouble moving it around, ensuring power availability on the go. The inclusion of a handle (molded in the case) makes carrying it a breeze, adding to its convenience.
Features
The GM3300i's control panel
When its oil levels are insufficient, the generator is on overload and the generator is ready, you will be informed by the featured light indicators.
Considering security aspects, the generator boasts an automatic low oil shut-off and an overload protection (circuit breaker), offering peace of mind throughout 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 standard documentation and an owner's manual (opens in a new tab) to facilitate setup, the Genmax GM3300i features extra accessories: funnel and tool kit.

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).
- Considering its weight, the Genmax GM3300i registers at a modest 47.4 pounds, placing it among the lighter inverter generators in the 2500 to 3500 rated wattage selection. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PGD40iSCO, with a dry weight of just 46 pounds.
- Given its rated noise level of 62 dBA, this inverter generator aligns with the average expected noise rating for devices of similar type and power. If noise is a concern for you, you could consider the Honda EU3000iS, which is one of the least noisy generators in its power range, rated at 50 dBA.
- In terms of its autonomy, the GM3300i can operate for up to 6 hours at a 25% load, placing it within the lower bracket among generators of similar type and power range. For those prioritizing autonomy, the Champion 200977 could be considered, as it offers one of the longest run times among generators with similar power output, reaching up to 22 hours.
- Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. When operating at 25% load, the inverter generator's fuel consumption is estimated at 0.17 GPH, placing it within the average range of gasoline usage among similarly powerful devices. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3500P is a device you could look out for.
Price comparison
As you can see from these interactive charts, when compared to other 2500-3500W inverter generators, the Genmax GM3300i 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.
