Zoom on the WEN DG4500iX

In a nutshell, the WEN DG4500iX is a portable inverter generator mostly geared towards:

  • RV travellers looking for even more independence
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • 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 buffs looking to enhance their experience

In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.

Power & Run Time

Thanks to its dual-fuel technology, the WEN DG4500iX delivers 120V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3,650W and a peak wattage of 4,500W. When propane-powered, it has 3,285 rated watts and 4,500 peak watts. Moreover, the parallel capability (parallel kit not included) enables power output to increase when paired with another similar or compatible unit, providing increased energy capacity and versatility for a wide range of needs.

The inverter generator features a classic hand-operated recoil starting mechanism and also a practical and straightforward electric starter (battery included). It is rated for a noise of 68 dBA (less noisy than an office).

In terms of run time, the DG4500iX, boasting a 4 gallons fuel tank, can run for around 12 hours at 50% load on a full tank of gasoline (with fuel consumption averaging 0.33 gallons per hour). Additionally, it provides around 12 hours (on a 20 lbs tank - propane consumption around 0.39 GPH) of operation with propane.

Featuring a <1% Total Harmonic Distortion (THD), the DG4500iX delivers a clean sine wave, guaranteeing the safety of your sensitive electronics plugged into its AC outlets.


The control panel is equipped with the following 4 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120V 30A (TT-30R) receptacle

In addition, it provides 2 DC outlets: there's two 5V USB ports (USB-A) 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.


With dimensions of L22.8 x W22.8 x H21.5 in, the traditional open frame design of the WEN DG4500iX ensures stability while allowing easy maintenance access to components and promoting effective air cooling. The featured design is ideal for the outdoors and all tough environments.

With a dry weight of 90.8 lbs, the DG4500iX can easily follow you wherever your power needs are. Furthermore, thanks to its wheel kit and its folding handle, shifting the generator once it's placed is a breeze.

The DG4500iX's control panel

The DG4500iX's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

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

Thanks to its built-in fuel gauge, the inverter generator allows you to quickly, conveniently, and easily check the gas level at a glance.

In terms of security, the generator features an overload protection (circuit breaker) and an automatic low oil shut-off, ensuring peace of mind during its use.

The unit also benefits from WEN's CO Watchdog carbon monoxide detection. This system measures the accumulation of poisonous CO gas while the generator is running. If the level of CO gas gets too high, the CO Watchdog system will automatically shut down the generator.

Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the WEN DG4500iX ships with supplementary accessories: oil, propane hose, funnel and tool kit.

The WEN DG4500iX versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN DG4500iX compare to inverter generators of similar power (between 3500 and 4500 W).

  • Weighing in at 90.8 lbs, the WEN DG4500iX fits within the expected weight range for inverters producing 3500 to 4500 rated watts. Regarding dry weight, one of the champions in the same power range is the Genmax GM4600iAEFIC, with a dry weight of only 58.4 lbs.
  • As this inverter generator has its lowest possible noise of 68 dBA, it should be considered noisier compared to its peers of a comparable running wattage. If noise level is one your key decisive factors, you may find the Westinghouse iGen4500DF appealing. It's rated at 52 dBA, making it one of the quietest generators in its power range.
  • At 50% load, the DG4500iX boasts a higher run time than most similarly powerful inverters, reaching around 12 hours. For those prioritizing autonomy, the Westinghouse iGen4500DF could be considered, as it offers one of the longest run times among generators with similar power output, reaching around 15 hours.
  • Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. When it comes to fuel efficiency among generators with similar wattage, this inverter generator lags behind, with a consumption rate of 0.33 GPH at a 50% load. If gasoline efficiency is at the top of your list, you may want to have a look at the Westinghouse iGen4500DF, which has great fuel efficiency, with a gas consumption of only 0.23 gallons per hour.

Price comparison

As you can see from these interactive charts, when compared to other 3500-4500W dual fuel inverter generators, the WEN DG4500iX 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.
