An Impressive Pedigree
One reason why WEN generators are so great is that a leading-edge manufacturer, WEN, backs them.
Founded in 1951, WEN has created and sold high-quality and affordable tools for over six decades. The company first made its mark by bringing electricity and tools together to produce power tools. The WEN research and development team played a critical role in developing a range of everyday tools, including electric soldering guns, chainsaws, electric engravers, electric jigsaws, and wet wheel sharpeners. WEN also pioneered random orbital technology, which is used in most car buffers, polishers, and waxers today.
WEN has since expanded to include a diverse array of products, including bench grinders, tool chests, hand tools, compressors, and gas portable inverter generators. By 2001, WEN had already sold over 50 million units.
As of 2022, WEN offers leading-edge customer service, reliable warranties, and a nationwide network of service technicians for routine maintenance. Just email the WEN team at email@example.com or call them at 1-800-232.1195 to arrange repairs.
WEN also has a generous return policy. If you believe that your purchase isn’t right for you, you’ll have a maximum of 30 days to return the product with the receipt. You’ll get a full refund of the purchase price.
WEN inverter generators are budget-friendly without sacrificing quality. Some models, like the WEN 56200i 2000-Watt Inverter Generator, have half the price tag of comparable models. Expect to pay around $1,600 for more powerful models and $200 for generators with lower power ratings. The average WEN generator costs around $600.
EPA- and CARB-Compliant
Most WEN generators, including the WEN GN625i 6250-Watt Gas Portable Inverter Generator, are EPA- and CARB-compliant. This means they:
- Can be sold and purchased in all 50 states, including California
- Have been tested by the EPA for meeting national eco-friendliness standards
Generally Lightweight and Portable
As many WEN generator reviews have shown, the vast majority of WEN generators are lightweight and portable. Smaller models, like the WEN 56200i 2000-Watt Inverter Generator, have ergonomic handles that let you carry and lift the device with ease.
While harder to lift above the ground, larger models — like the WEN GN625i 6250-Watt Gas Portable Inverter Generator — usually ship with a rugged wheel kit for portability. For models that don’t ship with wheel kits, you can buy the kit separately through the vendor.
WEN portable generators come in diverse shapes, sizes, and power ratings. WEN carries:
- Portable generators that can be easily lifted and carried
- Large generators that can power a house or RV
- Large yet portable generators like the WEN GN625i 6250-Watt Gas Portable Inverter Generator, which you can wheel from one area to another
WEN generators’ wattage output ranges from 1,250 watts to 13,000 watts.
Easy To Use
WEN generators are also easy to use. They typically come with:
- Light indicators for oil levels and generator status
- Overload protection
- Eco-friendly mode
- CO shutdown sensor
- Automatic low oil shut-off
Dual Fuel Usage
WEN also manufactures dual fuel generators. Unlike traditional gasoline generators, these beasts allow you to switch from gasoline to propane. Just use a switch or dial to switch between the two fuel types.
Keep in mind that you can run dual fuel generators with only one type of fuel. For example, you can run the WEN DF1100T 11,000/8,300-Watt Dual Fuel Gasoline and Propane Powered Electric Start Portable Generator on just gasoline or propane.
Dual fuel generators offer many advantages, including:
- Reliability: With two usable fuel types, you’re less likely to run out of options. Depending on your area, you may have more access to gasoline or propane. Dual fuel generators allow you to use both and rely on one type until you can stock up on the other.
- Safety: Propane is usually sealed safely in tanks, making it safer to store than gasoline. Gasoline is also more flammable.
Inverter vs Standard Generators
Inverter Generator vs. Standard Generator: A Simple Guide
WEN generators are designed in the United States, but they are manufactured in China.
WEN offers a two-year warranty for its generators. WEN’s sole obligation under this warranty is to replace defective parts that have not been subjected to alteration, abuse, misrepair, normal wear and tear, or careless handling by individuals other than WEN.
To make a claim under warranty, contact techsupport@wenproducts or 1-800-232-1195 with the following information:
• Shipping address
• Phone number
• Serial number
• Required part numbers
• Copy of your proof of purchase (i.e., receipt or email) that clearly states the month and year of purchase and the place of purchase
The place of purchase must be a direct vendor of WEN. Buying your generator through a third-party vendor, such as a pawn shop or secondhand merchant, will void the warranty.
You can buy WEN generators from the WEN website or through other retailers, including:
• Home Depot
Yes, you should add fuel stabilizer to your WEN generator before storing it, especially if it has gas in the fuel tank. If you don’t mix in fuel stabilizer, your generator may not start the next time you use it. Fuel stabilizer prevents gas from gumming and degrading the carburetor.
1.) Follow these steps to add fuel stabilizer to your generator:
2.) Add the correct amount of fuel stabilizer to the tank. WEN recommends Sta-Bil 360 if you don’t know which brand to use. Generally, a good ratio is one oz. of stabilizer per 2.5 gallons of fuel., but check the recommendations on your bottle.
3.) Run the engine for 10 minutes, which allows the treated fuel to go through the carburetor and engine.
4.) Follow the directions in your product manual to shut down the generator.
Your generator is now ready for storage.
Unlike traditional gas generators, inverter gas generators throttle the engine instead of running full tilt. They also have a rectifier for turning AC electricity into DC power, which is the type of power used in batteries. As a result, inverter generators can power and recharge battery-operated devices.
There are two main types of inverter generators:
Closed-frame: Quiet and compact, these inverters have protective shells that contain noise and absorb insulation, reducing their acoustic impact. They’re lightweight and suitable for powering small appliances.
Open-frame: As their name suggests, open-frame inverters have no outer shell, making them louder than their closed-frame counterparts. However, they’re still quieter than traditional generators. Open-framed generators can power small appliances as well as larger ones.
To determine whether your WEN generator can charge phones and laptops, look at what kind of energy it produces. If it produces clean power in a pure sine wave, you can use it to power sensitive electronics, including phones and laptops.
Other appliances that require pure sine wave inverters include:
• Some TVs
• Medical equipment
• CPAP machines with humidifiers
• Laser printers
• Cordless tool battery chargers
There are many reasons why your generator isn’t starting. These include:
• It’s out of gas. Check the gas tank to see if there’s enough gasoline. Add gasoline as needed.
• The battery is dead. Electric-start generator batteries may lose charge over time. Start the generator with the manual pull starter to kickstart the battery. If your unit doesn’t have a manual pull starter, you may need to use a third-party battery charger.
• The fuel valve is clogged or closed. The fuel valve may be clogged if your fuel tank is full but your generator refuses to start. The fuel valve controls the fuel flow from the fuel tank to the carburetor.
• The spark plug needs to be replaced. Build-up and debris in your spark plug can prevent your generator from starting. To see whether your plug needs to be replaced, use a spark plug wrench to remove the spark plug. Clean the plug with a knife as needed.
• The carburetor is air-locked or clogged. Finally, your carburetor may be air-locked or clogged. This is especially likely to happen if you’ve stored your generator for a long time without draining the carburetor. Turn off the fuel valve and open the carburetor drain to fix this. You can also remove the whole carburetor bowl to clean out stale fuel.
