Description

Zoom on the WEN GN400iX

The WEN GN400iX is the newer version of the GN400i. It's a compact and lightweight portable inverter generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in outdoor fairs, festivals or events
  • 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 sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The WEN GN400iX houses a 212 cc OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3,500W along with a peak wattage of 4,000W. Additionally, as the generator is parallel capable (WEN Parallel Connection Kit (opens in a new tab) not included), it can be linked to a second unit for more power.

With a noise rating of 67 dBA (less noisy than background music), the inverter generator features a conventional pull-start mechanism.

Thanks to a fuel capacity of 1.85 gallon, the GN400iX can operate for around 7 hours at 50% load with a full tank (fuel consumption around 0.26 GPH).

The GN400iX produces a clean sine wave: thanks to a <1.2% 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

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

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this WEN generator is RV Ready.

Portability

With its dimensions of L19.8 x W13.8 x H18.9 in, the conventional, open frame design of the WEN GN400iX offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

The GN400iX can be taken anywhere with you, thanks to its weight of 66.1 lbs. Moreover, grabbing and moving this product is made even easier by its open frame design.

Features

Panel of the WEN GN400iX

The GN400iX's control panel

The device’s light indicators will display if the oil level is too low, the generator is ready and the generator is overloaded.

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

Security-wise, this product benefits from an automatic low oil shut-off, a low fuel automatic shutdown and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

The unit also benefits from WEN's CO Watchdog carbon monoxide detection. This system measures the accumulation of poisonous CO gas while the generator is running. If the level of CO gas gets too high, the CO Watchdog system will automatically shut down the generator. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the WEN GN400iX, the following accessories are also included: funnel, 2 altitude kits and tool kit. An official storage cover is also available, as a separate purchase.

Emissions

The WEN GN400iX 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 and thus, may be used in forested areas.

The WEN GN400iX versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN GN400iX compare to inverter generators of similar power (between 3000 and 4000 W).

  • In terms of its dry weight, the WEN GN400iX stands at only 66.1 lbs, meaning that is one of the lighter inverters of the 3000-4000 rated wattage category If weight matters to you, one of the champions in this power range is the Pulsar PGD40iSCO with only 46 pounds.
  • Among the generators of a comparable running wattage, this inverter generator with a lowest noise of 67 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 Westinghouse iGen4500DF, whose lowest noise levels reach just 52 dBA.
  • As far as autonomy is concerned, providing around 7 hours of runtime with a full tank at a 50% load, the GN400iX falls into the low end in comparison with other inverters of a comparable power output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Westinghouse iGen4500DF, which is able to run for around 15 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Pulsar PGD40iSCO. With a fuel consumption of as little as 0.22 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 3000-4000W inverter generators, the WEN GN400iX 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.
