• People occasionally participating in sporting competitions, open-air performances and outdoor festivals
• DIYers who wish to improve their efficiency with tools
• Homeowners in need of an emergency backup power for their essentials
• Camping and tailgating buffs looking to enhance their experience

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

Featuring a 223 cc OHV 4-stroke engine, the Genmax GM4000Xi operates using gasoline, providing 120V, with a running wattage of 3,200W and a starting wattage of 4,000W.

Operating with a noise level of 66 dBA (less noisy than an office), the inverter generator starts up via a simple traditional pull-start mechanism.

Thanks to a fuel capacity of 1.7 gallon, the GM4000Xi can operate for up to 7 hours with a full tank (fuel consumption around 0.24 GPH).

The GM4000Xi produces a clean sine wave: thanks to a <5% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel features the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R)

120V 30A (TT-30R) receptacle

Moreover, it boasts 2 DC outlets: there's two 5V USB ports (1 x USB-A and 1 x USB-C) ideal for charging various electronic devices such as smartphones and tablets.

This Genmax generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

Measuring L18.1 x W14.4 x H18.9 in, the classic open frame construction of the Genmax GM4000Xi provides stability while enabling convenient maintenance access to components and adequate air cooling. The featured design is ideal for the outdoors and all tough environments.

With a dry weight of 61.7 lbs, the GM4000Xi can easily follow you wherever your power needs are. Furthermore, the open frame of the generator aids in holding and moving it to a different location.

Features

The GM4000Xi's control panel

Some light indicators allow you to instantly see if the generator is ready, the generator is overloaded and its oil levels are insufficient.

With its built-in fuel gauge, the inverter generator provides quick and convenient gas level checks.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Genmax GM4000Xi also comes with some accessories: tool kit and funnel are included.

The Genmax GM4000Xi versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Genmax GM4000Xi compare to inverter generators of similar power (between 2500 and 3500 W).

• Considering its weight, the Genmax GM4000Xi registers at a modest 61.7 pounds, placing it among the lighter inverter generators in the 2500 to 3500 rated wattage selection. if you wish to prioritize weight, the Pulsar PGD40iSCO is one of the top contenders in its power category, weighing only 46 pounds.
• As this inverter generator has its lowest possible noise of 66 dBA, it should be considered noisier compared to its peers of a comparable running wattage. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU3000iS, whose lowest noise levels reach just 50 dBA.
• In terms of its autonomy, the GM4000Xi can operate for up to 7 hours at a 25% load, placing it within the lower bracket among generators of similar type and power range. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 200977, which is able to run for up to 22 hours.
• Run time is a key metric, but it's dependent on the generator's fuel capacity. Therefore, discussing fuel efficiency is necessary to get the full picture. Among generators of similar output, this inverter generator ranks somewhat poorly in fuel efficiency, with an estimated consumption of 0.24 GPH at a 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Honda EU3200i, with a fuel consumption of 0.14 GPH could be in your good books.
