Description

Zoom on the WEN GN625iX

The WEN GN625iX is the newer version of the GN625i. It's a portable inverter generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • 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

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The WEN GN625iX's core is the 301 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 5000W and a peak wattage of 6250W.

The inverter generator features a conventional pull-start mechanism.

The fuel capacity of 4.2 gallons allows the GN625iX to operate for around 8.1 hours at 50% load with a full tank (fuel consumption around 0.52 GPH).

Sensitive electronics can be safely plugged in the AC outlets, as the GN625iX produces a clean sine wave, with a <1.5% Total Harmonic Disruption (THD).

Outlets

The control panel provides the upcoming 6 AC outlets:

Two Duplexes 120V 20A (5-20R)
120V 30A (TT-30R) receptacle
120/240V 30A (L14-30R) receptacle

In addition, it provides 2 DC outlets: there's two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.

With its TT-30R receptacle (TT as in 'Travel Trailer'), this WEN generator is RV Ready. In addition, as it features a twist-lock L14-30R receptacle, the GN625iX is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The WEN GN625iX has a conventional, open frame design, of the following dimensions: L27 x W25 x H24 in, which offers support and allows it to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 119.5 lbs. Nevertheless, thanks to its set of wheels and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the WEN GN625iX

The GN625iX's control panel

The control panel of the GN625iX includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

In addition to this info, the device’s light indicators will display if the generator is on overload, the oil level is too low and the generator is ready.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, 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).

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the WEN GN625iX also comes with some accessories: tool kit and 2 altitude kits are included.

Emissions

The WEN GN625iX is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

The WEN GN625iX versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN GN625iX compare to generators of similar power (between 4500 and 5500 W).

  • As far as its dry weight is concerned, the WEN GN625iX weighs just 119.5 pounds and thus, it is one of the lighter 4500 to 5500 rated wattage generators. If weight is your top priority, one of the champions in this power category is the WEN GN6000, weighing just 119 pounds.
  • As far as autonomy is concerned, providing around 8.1 hours of runtime with a full tank at a 50% load, the GN625iX falls into the low end in comparison with other devices of a comparable power output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Cat RP5500, 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. Standing at an estimated 0.52 GPH (gallon per hour) at a 50% load, this inverter generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.43 GPH, the Westinghouse WGen5300DFv is a device you could look out for.

Price comparison

As you can see from this interactive chart, when compared to other 4500-5500W generators, the WEN GN625iX is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
