Zoom on the WEN GN400i
In summary, the WEN GN400i is a compact and lightweight portable inverter generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Handcrafting enthusiasts who wish to work on-the-go
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
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 WEN GN400i
The WEN GN400i is powered by a 212 cc OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3500W as well as a peak wattage of 4000W. In addition, as it is parallel capable (WEN Parallel Connection Kit (opens in a new tab) not included), this power can be doubled when linked to another similar or compatible unit.
At a noise rating of 67 dBA (less noisy than a normal conversation), the inverter generator is started via a simple traditional pull-start mechanism.
Thanks to a fuel capacity of 1.85 gallon, the GN400i can operate for around 7 hours at 50% load with a full tank (fuel consumption around 0.26 GPH).
The GN400i produces a clean sine wave: thanks to a <1.2% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.
Outlets
The control panel features the following 3 AC outlets:
In addition, it provides 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.
This WEN generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').
Portability
The design of the WEN GN400i is a typical, open frame, with the dimensions of L19.8 x W13.8 x H18.9 in, offering support and stability and enabling the possibility of raising it above ground level. The device has been designed for tough environments and demanding outdoor use.
With a dry weight of 66.1 lbs, the GN400i can easily follow you wherever your power needs are. Moreover, grabbing and moving this product is made even easier by its open frame design.
Features
The GN400i's control panel
The light indicators show you if its oil levels are insufficient, the generator is on overload and the generator is ready.
Thanks to a built-in fuel gauge, the inverter generator allows you to quickly, conveniently and easily check the gas level at a glance.
The fuel shutoff feature turns off the flow of fuel, allowing for the GN400i to use up the remaining fuel from the carburetor before automatically shutting down. This helps fight the build-up and blockages caused by stagnant fuel inside of the carburetor, minimizing maintenance while prolonging the unit’s lifespan.
As for its security measures, the device features an overload protection (circuit breaker), an automatic low oil shut-off and a low fuel automatic shutdown, letting you use it with a peace of mind.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the WEN GN400i also comes with several accessories, including: oil, 2 altitude kits, tool kit and funnel.
Emissions
The WEN GN400i is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.
Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.

The WEN GN400i versus other generators
The following charts are provided to give you an idea of how some of the key specs of the WEN GN400i compare to generators of similar power (between 3000 and 4000 W).
- In terms of its dry weight, the WEN GN400i stands at only 66.1 lbs, meaning that is one of the lighter devices of the 3000-4000 rated wattage category In terms of weight, one of the champions in their power range is the Genmax GM3300i, standing at just 47.4 lbs.
- Because this inverter generator emits noise as low as 67 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If noise emissions are important to you, one of the least noisy generators of this power range is the Cat INV4000E with only 51 dBA.
- As far as autonomy is concerned, providing around 7 hours of runtime with a full tank at a 50% load, the GN400i falls into the low end in comparison with other devices of a comparable power output. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Predator 4375, with around 16 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This inverter generator, with an estimated fuel consumption of just 0.26 GPH (gallon per hour) at 50% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.
Here's a list of the most popular specific comparisons:
Price comparison
As you can see from this interactive chart, when compared to other 3000-4000W generators, the WEN GN400i 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.
