Description

Remember when you had clean and quiet portable power? The WEN 4500-Watt Inverter Generator provides clean energy, free of voltage spikes and drops, without all the noise of a regular generator. Produce up to 4500 surge watts and 3600 rated watts of power. Our 181cc engine operates at a modest 62 decibels at quarter load. This limits its invasiveness while camping, hunting, tailgating, and restoring backup power. The WEN 4500W Inverter Generator is also equipped with fuel shutoff. This feature turns off the flow of fuel, allowing for the generator to use up the remaining fuel from the carburetor before automatically shutting down. This helps fight the build-up and blockages caused by stagnant fuel inside of the carburetor, minimizing maintenance while prolonging the unit’s lifespan. Designed to mirror a pure sine wave, this generator limits total harmonic distortion to under 0.3 percent at no load and under 1.2 percent at full load, making it safe to run laptops, cellphones, monitors, tablets and other sensitive electronics. The lightweight 53-pound design makes for easy portability, while the ultra- efficient 1.27-gallon tank provides up to 5.6 hours of half-load run time. The fully-packed panel comes equipped with two three-prong 120V NEMA 5-20R receptacles, one 12V DC receptacle, one 120V TT-30R RV receptacle, an intelligent data meter, and two 5V USB ports. Maximize fuel economy by engaging the eco-mode button. This allows the generator's engine to automatically adjust its fuel consumption as items are plugged into and unplugged from the panel, preventing the unnecessary usage of gasoline. Need more energy? Easily link up any two 120V WEN inverter generators using a WEN 120V Parallel Connection Kit (sold separately) in order to share wattage amongst multiple units. Low-oil and low-fuel automatic shutdown combine with the built-in overload protection and indicator lights to safeguard both your generator and your electronics from damage. And because this is a WEN product, your inverter generator comes backed by a 3-year limited warranty, a nationwide network of skilled service technicians, and a friendly customer helpline. Remember when your generator powered your electronics safely and quietly? Remember WEN.

The media could not be loaded. Well packed and easy set up and break in. Seems to work very well and is pretty quiet. Great little generator with great power. Fired right up on a 20 gallon tank of propane.

    • Nice affordable generator
Style: 4500W
Used this little inverter on my house for 120v appliances. Works great and is decently quiet for the price. powers my fridge, boiler, lights and a tv while power is out. Pretty light weight for a generator and can be carried around easily. Comes with a floating nuetral out of the box so you dont double bond your house. ... show more

    • Great machine, a lot of features.
Style: Dual Fuel + 3600W + CO Sensor
I ordered this generator at the beginning of February 2026. When it arrived one of the corners of the box was damaged. I opened it up to find the generator undamaged (packaging was very good) but the regulator for the propane hose was broken. I started a warranty claim with WEN. They needed all the usual information about the order and the serial number of the machine which I provided. Wen sent me a replacement hose and regulator assembly at no cost. The generator itself seems to be very high quality. It's fully assembled out of the box, all you have to do is add fuel and oil. I've finished the break in period of 8 hours and have just over 12 on it now. So far it hasn't missed a beat. I'm impressed with how compact and lightweight it is for the output it provides. So far I haven't noticed any smoke or oil loss and it always starts on the first or second pull. I'm also impressed with the amount of features such as the info display and USB ports that a lot of much more expensive brands don't offer. ... show more

I bought this to use with my Arctic Fox camper after my built-in four year old Onan LP generator failed twice, the second time the part needed to repair it was no longer being made. The Wen is a reasonable weight, it starts easily and is a strait up bargain for a 3600 dual fuel inverter generator. It is not super quiet, but it is quieter than the Onan. I rated it four stars for a couple of reasons that mainly have to do with my intended usage. First, the 30 amp plug is located in a funky place. The attached pic shows it is impossible to seat the rv plug in the outlet because the panel below the plug sticks out. If left as it is the plug will eventually back out due to vibration. I am going to shave down the rv cable to make it work. My second issue is I was hoping to use my campers propane supply to run the generator. I have a regulated outlet on the rear of the rig to power a grill, propane firepit, etc. I was going to build a strait hose without a regulator to make this happen. Unfortunately, the pic supplied by Wen does not show the huge additional regulator on the LP hose. I assume this is to control the gas flow when in Eco mode. I am going to confirm this with Wen later. Until then, I will be toting a third propane tank around. I definitely recommend this generator. It will run my 10800 but AC if needed. Can get a propane refill, buy some gas. It is safe for today's electronics. Also, I emailed Wen questions before buying it and they generally responded in a couple of days. Update: The generator continues to start without issue….even if the temps are below 40 degrees. I have it hooked to a Flame King 20 pound propane tank with a float valve fuel level gauge, which takes the guesswork out of propane levels. I have seen some pretty eye opening claims about the Wen’s runtime on a 20p/5 gal tank..Wen claims 14 hours! I am seeing about six hours per tank after break in using a mix of eco and regular settings, mostly just charging my camper batteries and my Jackery generator. On the upside, some items that use propane get finicky when the gas levels get low. The Wen starts right up with 1/4 full tank. ... show more

    • Great generator for camping, easy to use, good power
Style: 3600W
This arrived quickly and initial set up was easy. My Amazon delivery driver was very friendly. I cycled this for 8 hours, on and off eco mode, first no, then minimal load, to break it in. Afterwards, I took it into my kitchen (please don't tell my wife) and I changed the oil. The next day, I tested it out on my camper and used the air conditioning (13K BTU). The generator accepted the load with no issues. The generator is very easy to start, even when cold. I like the gauges and I find it to be pretty quiet. The size is great, because if I choose to, I can store it in my camper, under my lower bunk storage. Even when doing this - I noticed no gasoline smell after driving home. I'm curious to monitor the fuel consumption. On a hot day of testing with the A/C on constantly, I only got around 4 hours on a tank. But again, the generator was barely broken in, and it was a very hot day. All in all I do not foresee any issues with this generator. I think it will serve my needs well. It seems very well built and is easy to use. I like having the power option when I need it. I do recommend this generator for camper use and otherwise. ... show more
