Description

Keep your family safe during power outages and natural disasters with the WEN WEN 6,250-Watt RV and Transfer-Switch Ready Inverter Generator. The included inverter provides clean energy, free of voltage spikes and drops. (source: WEN (opens in a new tab))

Zoom on the WEN GN625i

In a nutshell, the WEN GN625i is a portable inverter generator mostly geared towards:

  • RV travellers looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events
  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • 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 hobbyists looking for a portable power source

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 GN625i houses a 301 cc OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 5,000W along with a peak wattage of 6,250W.

The inverter generator features a conventional pull-start mechanism.

Thanks to a fuel capacity of 4.2 gallons, the GN625i can 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 GN625i produces a clean sine wave, with a <1.5% Total Harmonic Distortion (THD).

Outlets

The control panel features the upcoming 6 AC outlets:

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

Additionally, it features 2 DC outlets: there's two 5V USB ports 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. In addition, as it features a twist-lock L14-30R receptacle, the GN625i 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 dimensions of the WEN GN625i, which are L27 x W25 x H24 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 119.5 lbs make it incredibly difficult to manually lift and transport. 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.

The GN625i's control panel

The GN625i and its control panel include a convenient meter showing you voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

In addition to this info, the device’s light indicators will display if its oil levels are insufficient, the generator is ready and the generator is on overload.

The inverter generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the WEN GN625i also is packed along with the following accessories: 2 altitude kits and tool kit. An official storage cover is also available, as a separate purchase.

Emissions

The WEN GN625i is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used in forested areas.

The WEN GN625i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN GN625i compare to generators of similar power (between 4500 and 5500 W).

  • Regarding its weight, the WEN GN625i only weighs in at 119.5 pounds, which means it's one of the lighter generators in the 4500-5500 rated wattage range. In terms of weight, one of the champions in their power range is the Genmax GM6000XiE, standing at just 106.9 lbs.
  • As far as autonomy is concerned, providing around 8.1 hours of runtime with a full tank at a 50% load, the GN625i falls into the low end in comparison with other devices 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 Predator 6500, boasting with around 14.5 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 has an average fuel consumption among comparably powerful devices, as it reaches 0.52 GPH (gallon per hour) at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.41 GPH, the Genmax GM5500i 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 GN625i 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.
