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 sporting competitions, open-air performances and outdoor festivals
  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • 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

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 is powered by a 301 cc OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 5,000W as well as a peak wattage of 6,250W.

This inverter generator features a conventional pull-start mechanism.

The fuel capacity of 4.2 gallons allows the GN625i 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 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

It also sports 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.

This WEN generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'). In addition, since the GN625i bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The WEN GN625i 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 featured design is ideal for the outdoors and all tough environments.

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. However, this lack of maneuverability is compensated by its set of wheels and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the WEN GN625i

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 ready, the generator is on overload and its oil levels are insufficient.

The fuel level of the inverter generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the WEN GN625i, the following accessories are also included: 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. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, making it usable 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).

  • As for its weight, the WEN GN625i weighs only 119.5 pounds, making it one of the lighter generators in the 4500-5500 rated wattage category. In terms of weight, one of the champions in their power range is the WEN GN5600, standing at just 103.6 lbs.
  • Autonomy-wise, with around 8.1 hours on a full tank at a 50% load, the GN625i is on the low end when compared to other generators of a similar power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 6500, reaching 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. As this inverter generator uses an estimated 0.52 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you wish to further improve in the area of fuel efficiency, the WEN GN5602X, which boasts with a gas consumption of only 0.35 GPH, may be the right generator for you.

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.
