Description

Remember when your backup plan had a backup plan? Whether we're providing your home electricity during a crisis or charging your family's cellphones at the campgrounds, WEN has been reliably lighting up lives since 1951. Now, with the WEN 14500-Watt Tri Fuel Electric Start Generator, you’ll be able to pull power from three different sources. Simply select your preferred method – gasoline, propane, or natural gas – and power on. With 14500 surge and 11500 running watts on gasoline, 12500 surge and 10300 running watts on LPG, and 10500 surge and 8750 running watts on NG, it’s durable enough for the job site and reliable enough for home emergency backup. Electric start lets you power up your generator with the turn of a key, and includes a recoil starter as backup. Our packed panel features four three-prong 120V NEMA 5-20R outlets, a 120V/240V 30A NEMA L14-30R outlet, a 120V/240V 50A NEMA 14-50R outlet, and a standard 12V DC automotive outlet. The onboard data meter digitally displays voltage, frequency, total runtime, and session runtime to help keep tabs on maintenance intervals. Run your lights, TV, refrigerator, sump pump, power tools, or other essentials with ease. The wheel and handle kit makes transportation easier than ever, while the included six-foot LPG hose allows for immediate connection to propane tanks. Thanks to its 240V capability, powerful 500cc engine, and included NG quick-connect adapter, this generator is the perfect portable alternative to hefty and expensive standby units (NOTE: NG hose not included / sold separately, part no. TF1450X-1431). Simply connect the NEMA L14-30R or 14-50R outlet to your transfer switch for power when and where you need it. Fill the gas tank with up to 8.2 gallons of gasoline for a half-load runtime of up to 12 hours. Compatible with the WEN 56413 Generator Cover and the WEN GNA273 Magnetic Dipstick. And because it’s a WEN product, your generator comes backed by a three-year limited warranty, a nationwide network of skilled service technicians, a stocked inventory of replacement parts, and a friendly customer helpline. Remember when you didn’t have to worry about the power going out? Remember WEN.

    • Great value. Nice features.
Size: 8000W, Dual Fuel + CO Alarm
So far so good. Good 1st impression. Great value. All the bells and whistles I was looking for at a good price. Came with every but the oil n gas. * WEN doesn’t make an exact fit cover or magnetic drain plug. The xl cover will fit. Dual fuel Big power 120/240 3 prong/4 prong Low Oil/co2 Electric starter Easy pull start Wheel and handle Kit Easy assembly Easy dipstick and drain access 3yr warranty Cons: Frame Paint Is weak. Rocker switch, control end isn’t protected if you tip Up to Work on/push against wall etc * I may add a pool noodle or rubber bumper to that end. Metal Tanks tend to rust. Plastic would have been better Wheels seem cheapish. Also cheap to replace If ever needed. 8k unit is heavy. Not for throwing in the truck bed etc. Fuel gauge seems cheapish ehh ... show more

    • RV Ready Generator, here we go!
Size: 11000W, Dual Fuel
Okay, So not so funny thing about the delivery, which isn't Wen's fault, the UPS didn't know how to count house numbers and delivered it to a house two houses up from mine. This machine, isn't a light weight. In the box, it is heavy and awkward, even with a two-wheeler. I had a bit of trouble getting this generator to start, but when I call for support the gentleman on the phone walked me through some steps I hadn't already taken and after some work, we got it running first on gasoline then on propane. Tested the electric output and it'll run my 37ft RV trailer just fine. The only Detractor is the noise level of the generator, but it's not excessively loud, but you can here it inside the trailer. The real test will be to see how long a 20lb tank of propane will last for our first outback campout. ... show more

    • I am shocked... pun intended
Size: 11000W, Dual Fuel
I have the worst luck with brand new items. Doesn't matter what it is, if I buy it new, it won't work. This generator is the first brand new thing I've bought that works perfectly. I was shocked when it started up instantly right out of the box. I even tried the pull cord... engine started with the slightest tug. It runs very smooth, it makes lots of power. It's about as loud as you would expect any generator to be. It's not quiet, but none of them are. The quality of this generator... also shocking. For the price of it, compared to other brands, I was expecting loose bolts, cheesy brackets, etc etc. It is actually very well built. It's heavy, strong, it doesn't rattle at all. Very tight. I'm confident this unit will last a long time. My favorite part, because I'm a mechanic, is the easy access to the engine parts that will need regular service. Everything was placed in the perfect spot to be worked on without foul language and throwing tools involved. I had my wife and children start it up and get it ready as if a power outage occurred. Using it is a breeze. Everything is labelled clearly, easily accessible, and it all works as it should. The only things you need to assemble is the wheels and handles. Super simple to do. Very clear instructions. The Generator is heavy, without wheels, you better drink some milk if you're gonna move it. Once the wheels and handles are on it, it so easy to roll around, you forget how heavy it really is. My 90lb daughter has no problem moving it around on it's wheels. I'm very pleased with this generator. I highly recommend this model and brand. You're getting a great product without a huge price tag. UPDATE. It's now 5/18/2022. Had to use the generator to power my house due to a power outage for a few days. It hadn't been started in about 2-3 months. Bumped the key, started right up. I've had it running on gas and it's used an average of 1 tank per 10-11 hours. Hasn't burned any oil. Level perfect every time. Doesn't overheat, runs real smooth. I shut it off every other time I added gas. Starts right back up and goes to work. I use only Non-Ethanol gas to protect the carb. Regular gas will gum up and clog jets when it sits. I also use Synthetic oil, (Royal Purple) in the engine. I purchased the WEN cover for it and the Generator looks brand new, even after sitting outside for over a year. And yet another update 11/21/2022 So the generator has been running for 300+hrs straight, powering my house. Day 12, Battery died. Generator shut down because without battery power, the solenoid in the carb closes when it loses 12v power from the battery. Not a big deal, jump started it off my lawn tractor, started right up and gave me time to go get a new battery. I plugged a charger into the generator to keep the battery charged while I went and bought a new battery. It flashes code P50 when you need to change the oil. Do that, don't ignore it. (takes about 3 min) It flashes P100 when you need to do a more extensive service. Do that also, don't ignore it. (takes 10 min) This Generator is screaming 23/7 days a week now. It's a beast. It's doing it's job very well in my opinion. Still solid, no rattles, nothing coming loose, and producing power like it has since day one. Fuel consumption - About 10-11hrs on a tank. I changed to an NGK BPR7ES plug and run 89 octane gas, Royal Purple Full Synthetic Oil, and It's a solid 12-14hrs per tank of gas. I hope all this actually helps someone. ... show more

    • Loud and robust.
Size: 11000W, Dual Fuel
very, very loud. Good robust design, well organized layout. Some trouble with vapor lock on the liquid fuel. Easily solved by running it out of gas when you store it, or cracking the seal on the fuel float if you have trouble getting it started. Minimal use for three years, still starts and runs fine. ... show more
