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 truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners in need of an emergency backup power for their essentials
  • 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 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 is started via a conventional 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.

Delicate electronics can be plugged in an AC outlets safely, as the GN625i generates a clean sine wave, reaching a <1.5% Total Harmonic Disruption (THD).

Outlets

The control panel features the following 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.

This WEN generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer'). In addition, due to the featured twist-lock L14-30R receptacle, the GN625i is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The design of the WEN GN625i is a typical, open frame, with the dimensions of L27 x W25 x H24 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.

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, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.

Features

The GN625i's control panel

The control panel of the GN625i 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, when its oil levels are insufficient, the generator is on overload and the generator is ready, you will be informed by the featured light indicators.

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.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the WEN GN625i also comes with several accessories, including: 2 altitude kits and tool kit.

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 and therefore, can be used in forested areas.

Product Video

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 If weight is your top priority, one of the champions in this power category is the WEN GN6000, weighing just 119 pounds.
  • 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 concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Cat RP5500, boasting with around 15 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This inverter generator reaches an estimated fuel consumption of 0.52 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse WGen5300DFv, with a fuel consumption of 0.35 GPH could be in your good books.

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.
