Zoom on the Genmax GM4000Xi

In a few words, the Genmax GM4000Xi is a compact and lightweight portable inverter generator perfectly suited for:

• RV travellers looking for even more independence
• Occasional participants of outdoor events, competitions, concerts and festivals
• Handcrafting enthusiasts who wish to work on-the-go
• Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
• Camping and tailgating hobbyists looking for a portable power source

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

The Genmax GM4000Xi houses a 223 cc OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3,200W along with a peak wattage of 4,000W.

The inverter generator features a classic hand-operated recoil starting mechanism. It is rated for a noise of 66 dBA (less noisy than background music).

Thanks to its 1.7 gallon fuel tank, the GM4000Xi can run continuously for up to 7 hours on a full tank (with an average fuel consumption of approximately 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 3 AC outlets as follows:

Duplex 120V 20A (5-20R)

120V 30A (TT-30R) receptacle

Furthermore, it has 2 DC outlets: there's two 5V USB ports (1 x USB-A and 1 x USB-C) with which charging of electronics like mobile phones and tablets is made convenient.

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

At L18.1 x W14.4 x H18.9 in, the standard open frame design of the Genmax GM4000Xi delivers stability alongside easy maintenance access to components and good air cooling. The featured design is ideal for the outdoors and all tough environments.

At 61.7 lbs, the GM4000Xi is easily managed, ensuring it can be brought along wherever you need power. Moreover, grabbing and moving this product is made even easier by its open frame design.

Features

The GM4000Xi's control panel

The light indicators show you if the oil level is too low, the generator is on overload and the generator is ready.

Thanks to its built-in fuel gauge, the inverter generator allows you to quickly, conveniently, and easily check the gas level at a glance.

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: funnel and tool kit 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 weight is a key factor for your needs, the Pulsar PGD40iSCO is noteworthy for being one of the top contenders in this power range, with a dry weight of 46 pounds.
• Among the generators of a comparable running wattage, this inverter generator with a lowest noise of 66 dBA can be judged as noisy. 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.
• As far as autonomy is concerned, providing up to 7 hours of runtime with a full tank at a 25% load, the GM4000Xi falls into the low end in comparison with other inverters of a comparable power output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Champion 200977, boasting with 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 somewhat less fuel-efficient than devices of comparable output: its estimated fuel consumption reaches 0.24 GPH at a 25% load. If minimizing fuel usage is one of your key priorities, the Honda EU3200i is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.14 gallons per hour.
