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 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
  • Camping and tailgating buffs looking to enhance their experience

The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.

Power & Run Time

Running on gasoline, the WEN GN400iX utilizes a 212 cc OHV 4-stroke engine to deliver 120V, offering a running wattage of 3,500W and a starting wattage of 4,000W. Furthermore, its parallel capability (WEN Parallel Connection Kit (opens in a new tab) not included) allows for increasing of power output when connected to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.

The inverter generator is rated for a noise of 67 dBA (less noisy than a normal conversation). Its starting mechanism is based on a simple traditional pull-start mechanism.

With a fuel capacity of 1.85 gallon, the GN400iX can run for around 7 hours at 50% load when the tank is full (fuel consumption is approximately 0.26 gallons per hour).

The <1.2% Total Harmonic Distortion (THD) of the GN400iX ensures a clean sine wave output, providing a secure power source for your sensitive electronics through its AC outlets.

Outlets

The control panel includes the following 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

In addition, it provides 2 DC outlets: there's two 5V USB ports (USB-A) enabling convenient charging of devices like mobile phones and tablets.

With its TT-30R receptacle (TT as in 'Travel Trailer'), this WEN generator is RV Ready.

Portability

With dimensions of L19.8 x W13.8 x H18.9 in, the standard open frame design of the WEN GN400iX provides stability and easy maintenance access to components, as well as good air circulation. The generator is designed for ideal use outdoors and in rough environments.

With a dry weight of 70 lbs, the GN400iX is convenient, ensuring it can be taken wherever power is needed. Furthermore, the open frame of the generator aids in holding and moving it to a different location.

Features

The GN400iX's control panel

Light indicators on the device will signal if the generator is ready, the generator is overloaded and the oil level is too low.

The inclusion of a built-in fuel gauge in the inverter generator streamlines gas level checks for quick and convenient assessments.

In terms of security, the generator features an overload protection (circuit breaker), a low fuel automatic shutdown and an automatic low oil shut-off, ensuring peace of mind during its use.

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.

In addition to the traditional documentation and an owner's manual (opens in a new tab) to help you get started promptly, the WEN GN400iX also includes several accessories: 2 altitude kits, funnel and tool kit. An official storage cover is also available, as a separate purchase.

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).

  • Weight-wise, the WEN GN400iX has only 70 lbs, which renders it one of the lighter inverter generators which produce 3000 to 4000 rated watts. If weight is your top priority, one of the champions in this power category is the Pulsar PGD40iSCO, weighing just 46 pounds.
  • When stacked up against other devices of similar running wattage, this inverter generator's lowest possible noise rating of 67 dBA places it in the louder category. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4000DFc, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • The GN400iX's autonomy is somewhat low end compared to devices of its type and power range, as it reaches only around 7 hours at 50% load on a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Westinghouse iGen5000DF, boasting with around 15 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. This inverter generator is one of the more fuel-efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.26 GPH (gallon per hour) at 50% load. If you wish to further improve in the area of fuel efficiency, the Pulsar PGD40iSCO, which boasts with a gas consumption of only 0.22 GPH, may be the right generator for you.

Price comparison

As you can see from these interactive charts, 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.
