Description
The WEN DF402iX has 120V and a lot of power and versatility thanks to its dual-fuel technology. When it is running on gasoline, it has a running wattage of 3,500W and a peak wattage of 4,000W. When powered by propane, it has a rated 3200 watts and a peak of 3600 watts. Also, the generator can be connected to a second unit to make more power (a GNA50i parallel kit is not included). The pull-start mechanism on this inverter generator makes it easy to get it going. With a fuel capacity of 1.85 gallons, the DF402iX can run for about 7 hours at 0.5 load using gasoline (fuel consumption is approximately 0.26 GPH). If you use propane instead, it can run for about 9.5 hours on a 20-pound tank (propane uses about 0.49 GPH). The DF402iX makes a clean sine wave. With a Total Harmonic Distortion (THD) of less than 1.2%, you can safely plug your sensitive electronics into the AC outlets.
Outlets
On the control panel, there are 3 AC outlets: a duplex 120V 20A (5-20R) outlet and a 120V 30A (TT-30R) outlet.
Also, it has 2 DC outlets: there are two 5V USB ports (USB-A) that make it easy to charge devices like cell phones and tablets.This WEN generator is ready for an RV because it has a TT-30R plug (TT stands for “Travel Trailer”).Features
The lights on the device will show if the oil level is too low, if the generator is overloaded, or if it is ready to be used.
The inverter generator has a built-in fuel gauge that makes it easy to see at a glance how much gas is in the tank.As for safety, the device has an automatic low oil shut-off, an overload protection (circuit breaker), and an automatic low fuel shut-off, so you can use it without worry.The unit also works well because WEN’s CO Watchdog can detect carbon monoxide.This system keeps track of how much CO gas is being made while the generator is running.If there is too much CO gas, the CO Watchdog system will turn off the generator automatically.It’s a nice extra safety measure, but don’t forget to always take your generator outside.The WEN DF402iX package comes with basic paperwork and an owner’s manual that will help you start the generator right away.It also comes with a propane hose, tool kit, 2 altitude kits, and a funnel.You can also buy a storage cover that is made by the company.Mobility
The WEN DF402iX is 19.8 inches long, 13.8 inches wide, and 18.9 inches high.
It has a typical open frame design that makes it stable and allows it to be lifted off the ground.This type of design is great for tough environments and heavy outdoor use.Since the DF402iX weighs only 66.1 lbs, you can take it anywhere you need power.Also, the open frame makes it very easy to grab the frame and move it.Product Videos

- We compared more than 500 portable generators at 50% load. We found that there is “skewed right” distribution for the difference between 50% load and 25% load and the median comes at 1.43. With this number we converter all the 25% load runtime to 50% load. Same with the propane efficiency, where median is 1.38.
- For some generators where propane runtime was not given, we used NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs. of propane = 1 gal of gasoline. All propane runtime is for 20 lbs. propane tank (4.7 gallons).
- Unlike many other sites, we actually tried to find out information about each of the above requirements. However, we are human and are therefore capable of the odd oversight or mistake. Please let us know if you spot any missing or erroneous values so that we can fix them.
About the Manufacturer
Nick Anton started WEN Products, an American power tool manufacturer and distributor, in 1951.
WEN Products says that its research in random orbital technology contributed to the creation of current chainsaws, soldering tools, and wet sharpeners.The Illinois-based corporation increased the range of power tools that were available through its distribution network, including presses, drills, and of course, power generators.WEN is a distributor, and the majority of the products in its inventory are branded imports from Asian manufacturers.Warranty Information
