Power & Run Time
The Genmax GM3300i
With a 145 cc (5.2 hp) Dinking OHV 4-stroke engine, the Genmax GM3300i operates on gasoline, providing 120V, with a running wattage of 3,000W and a starting wattage of 3,300W. Additionally, the parallel capability (parallel kit (opens in a new tab) not included) facilitates doubling of power output when linked to another similar or compatible unit, offering enhanced energy capacity and reliability for diverse requirements.
The inverter generator is rated for a noise of 62 dBA (just slightly more noisy than an office). Its starting mechanism is based on a classic hand-operated recoil starting mechanism.
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).
Thanks to its low <3% Total Harmonic Distortion (THD), the GM3300i produces a clean sine wave output, making it safe for your sensitive electronics when utilizing the AC outlets.
Outlets
The control panel features the upcoming 3 AC outlets:
Furthermore, it has 2 DC outlets: there's two 5V USB ports (USB-A) providing convenient charging capabilities for mobile phones, tablets, and other electronic devices.
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
Thanks to its closed inverter generator design (L18.9 x W11.4 x H17.3 in), the Genmax GM3300i not only offers superior aesthetics but also operates with reduced noise levels compared to a typical, open frame generator. The design follows the contemporary trends and is perfect for recreationally generating power.
The GM3300i boasts a weight of merely 47.4 lbs, solidifying its reputation as a lightweight, easily transportable generator. As it can be moved by a single person without much effort, the generator and its power can be enjoyed 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
The light indicators show you if the generator is ready, the generator is overloaded and the oil level is too low.
In terms of security, the generator features an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during its 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 GM3300i also includes several 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 weight matters to you, one of the champions in this power range is the Pulsar PGD40iSCO with only 46 pounds.
- 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 you value reduced noise levels, the Honda EU3000iS could be worth considering. It's one of the quietest generators in its power range, rated at 50 dBA.
- As for its autonomy, the GM3300i, with an autonomy of up to 6 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 matters, it's heavily influenced by the fuel tank's capacity. Hence, it's important to consider fuel efficiency alongside. This inverter generator is one of the more fuel-efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.17 GPH (gallon per hour) at 25% load. If you wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the Honda EU3200i, which has an impressively low fuel consumption of 0.14 GPH.
The bottom line
- CO DETECT technology
- RV Ready
- Parallel capable
- Inverter
- Lightweight (47.4 lbs)
- Fuel efficient
- Acceptable noise (62 dBA)
- No data center
- 1-year warranty
- Relatively low run time
