Zoom on the WEN DF402iX
In a nutshell, the WEN DF402iX is a compact and lightweight portable inverter generator mostly geared towards:
- RV travellers who wish to upgrade their experience to another level
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
Power & Run Time
The dual-fuel technology of the WEN DF402iX allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3600W and a starting wattage of 4000W. If propane-powered, it gives 3200 rated watts and 3500 starting watts. Moreover, since it is parallel capable (GNA50i parallel kit (opens in a new tab) not included), its power may be increased if linked to a second compatible unit.
This inverter generator gets running thanks to a conventional pull-start mechanism.
Regarding its running time, the DF402iX, with a 1.85 gallon fuel capacity can operate for around 7 hours at 50% load with a full tank of gasoline (fuel consumption around 0.26 GPH). When using propane, it can run for around 9.5 hours (on a 20 lbs tank - propane consumption around 0.49 GPH).
As the DF402iX produces a clean sine wave, with a <1.2% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.
The control panel includes the following 3 AC outlets:
Furthermore, it has 2 DC outlets: there's two 5V USB ports (USB-A) 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.
The dimensions of the WEN DF402iX, which are L19.8 x W13.8 x H18.9 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
The DF402iX can be taken anywhere with you, thanks to its weight of 66.1 lbs. Additionally, the generator’s mobility is also improved by its open frame design, as it can be easily grabbed and shifted.
Some light indicators allow you to instantly see if the oil level is too low, the generator is ready and the generator is on overload.
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.
As far as security is concerned, the generator can be used with a peace of mind, as it features a low fuel automatic shutdown, an overload protection (circuit breaker) and an automatic low oil shut-off.
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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the WEN DF402iX also comes with some accessories: 2 altitude kits, propane hose, tool kit and funnel are included. An official storage cover is also available, as a separate purchase.
The WEN DF402iX 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, so it is adequate for use in forested areas.
The WEN DF402iX versus other generators
The following charts are provided to give you an idea of how some of the key specs of the WEN DF402iX compare to inverter generators of similar power (between 3500 and 4500 W).
- As for its weight, the WEN DF402iX weighs only 66.1 pounds, making it one of the lightest inverter generators in the 3500-4500 rated wattage category.
- Regarding its autonomy, the autonomy of the DF402iX, reaching around 7 hours at a 50% load, can be considered as low end, compared to other inverters of a roughly equal output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse iGen4500DF, as it provides around 15 hours.
- While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This inverter generator, with an estimated fuel consumption of just 0.26 GPH (gallon per hour) at 50% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4500DF. With a fuel consumption of as little as 0.23 GPH, it is one of the most efficient generators currently on the market.
As you can see from this interactive chart, when compared to other 3500-4500W dual fuel inverter generators, the WEN DF402iX 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.
