Zoom on the WEN GN625i

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

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
  • Homeowners in need of an emergency backup power for their essentials
  • Camping and tailgating hobbyists looking for a portable power source

In the forthcoming sections, you'll delve into its power characteristics, the various outlets it offers, its overall portability, and the additional features it boasts.

Power & Run Time

The WEN GN625i's engine, 301 cc OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 5,000W and reaches a peak wattage of 6,250W.

This inverter generator features a standard recoil pull-rope starting mechanism.

Featuring a 4.2 gallons fuel tank, the GN625i can provide power for around 8.1 hours at 50% load on a full tank (with fuel consumption averaging 0.52 gallons per hour).

The <1.5% Total Harmonic Distortion (THD) of the GN625i ensures a clean sine wave output, providing a secure power source for your sensitive electronics through its AC outlets.

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 with which charging of electronics like mobile phones and tablets is made convenient.

Thanks to its TT-30R receptacle (TT meaning 'Travel Trailer'), this WEN generator is RV Ready, ready to power your recreational vehicle with ease. In addition, since it boasts a twist-lock L14-30R receptacle, the GN625i is engineered to be transfer switch ready, ensuring easy integration with your breaker box to provide backup power to your home during outages.

Portability

At L27 x W25 x H24 in, the WEN GN625i boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The featured design is ideal for the outdoors and all tough environments.

Though weighing 119.5 lbs, the generator remains classified as 'portable,' indicating its capability to be moved, though its weight could pose transport challenges. Nevertheless, it can still be moved quite conveniently with the help of its set of wheels and its folding handle, once it is placed on the ground.

The GN625i's control panel

The GN625i's control center features a convenient meter, providing voltage, frequency, and lifetime hours data to aid you with the monitoring of its status and activity.

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

The inverter generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

Regarding security, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during operation.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the WEN GN625i's package also includes these accessories: tool kit and 2 altitude kits. An official storage cover is also available, as a separate purchase.

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).

  • As far as its dry weight is concerned, the WEN GN625i weighs just 119.5 pounds and thus, it is one of the lighter 4500 to 5500 rated wattage generators. Weight-conscious users may find the Champion 201238 appealing, as it is one of the top contenders in this power range, weighing just 101.4 pounds.
  • 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 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 NorthStar c5500, with around 15.1 hours.
  • Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. With a fuel usage of about 0.52 GPH at a 50% load, this inverter generator falls within the typical gasoline consumption range observed in comparably powerful products. To prioritize fuel savings, we advise considering the WEN GN5602X, which stands out for its gasoline efficiency, consuming just 0.35 gallons per hour.

Price comparison

As you can see from these interactive charts, when compared to other 4500-5500W inverter 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.
