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 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 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 following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The WEN GN625i is powered by a 301 cc OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 5000W as well as a peak wattage of 6250W.

This inverter generator gets running thanks to a simple traditional pull-start mechanism.

With a full tank, the GN625i can operate for around 8.1 hours at 50% load (fuel consumption around 0.52 GPH), thanks to its fuel capacity of 4.2 gallons.

The GN625i produces a clean sine wave: thanks to a <1.5% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the 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

It also sports 2 DC outlets: there's two 5V USB ports 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, because the GN625i is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

The WEN GN625i has the following dimensions: L27 x W25 x H24 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

Since the generator weighs 119.5 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). 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

The GN625i's control panel

The GN625i's status and activity may be monitored conveniently via the control panel, as it features a convenient meter, which displays voltage, frequency and lifetime hours.

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

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.

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

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the WEN GN625i also comes with some accessories: 2 altitude kits and tool kit are included. An official storage cover is also available, as a separate purchase.

Emissions

The WEN GN625i 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, which makes it suitable for use 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).

  • In terms of its dry weight, the WEN GN625i stands at only 119.5 lbs, meaning that is one of the lighter devices of the 4500-5500 rated wattage category In terms of weight, one of the champions in their power range is the Genmax GM6000XiE, standing at just 106.9 lbs.
  • As for its autonomy, the GN625i, with an autonomy of around 8.1 hours at a 50% load, is placed on the low end among the generators of its kind. 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. 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 fuel consumption is your top priority, we suggest to check out the Genmax GM5500i, which has a fuel consumption of only 0.41 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, 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.
