WINCO WL12000HE 10,800W 50A Electric Start Portable Generator
Built for those who depend on reliable power every day, the WINCO WL12000HE 10,800W Electric Start Portable Generator delivers the strength, endurance, and professional-grade performance that Winco is known for. Designed, engineered, and assembled in the USA, this generator provides an ideal combination of power and portability for contractors, emergency responders, and serious homeowners who refuse to compromise on quality.
At the core of the WL12000HE is the Honda GX630 V-Twin engine, producing 20.8 HP of consistent and efficient power. This commercial-grade engine features digital CDI ignition with variable timing, full-pressure lubrication, and a low-oil shutdown system to ensure smooth operation and long engine life. Coupled with a Mecc Alte industrial generator end featuring copper windings and ±5% capacitor voltage regulation, it delivers clean, stable energy with less than 6% total harmonic distortion — safe for sensitive electronics and rugged enough for heavy tools.
Durability is built into every detail. The WL12000HE’s powder-coated galvanealed steel frame provides superior corrosion resistance, while the 15-gallon fuel tank delivers an impressive 9.4 hours of runtime at full load. The control panel includes GFCI-protected duplex outlets, a 50A twist-lock receptacle, and 30A 240V connections, giving you flexible options for any setup. Every Winco unit is 100% load tested at the factory, ensuring it’s ready to perform the moment it arrives.
Whether it’s for powering a construction site, keeping your home running during an outage, or supporting mobile equipment, the WL12000HE 50A generator stands as one of the most capable and dependable portable units in its class — proudly built in America to deliver power you can trust.

VERY Heavy, very fast shipping
This machine is definitely well constructed using heavy gauge tubular and plate steel bolted together using oversized fasteners. It's built like a tank.
Uses a brushless Mecc Alte Alternator.
15 gal fuel tank is steel with a large, quality metal, 1/4 turn cap with a debris cup/screen and large opening.
The only plastic on this machine that I can find is on the Honda engine's air filter and dust covers and the start/key/choke control bracket. Comes full of oil (full synthetic I believe). The "YourGen" backlit display is real nice. I just wish it showed actual watts or amps instead of load bars. But it's not necessary and it would likely require sensitive and probably delicate circuitry to show accurate current readings anyway. It does display L1, L2 then L1+L2, voltages, Hertz, run time (1/10 hr resolution) and RPM that continuously scrolls while running.
Run hours always display when off, and the engine also has a run hour display that shows when the key is switch on.
Has no pull start option, electric start only.
I put a 4800 watt (240v) load and ran for about 30 min without ANY reduction in voltage or Hz during this test. Engine ran very smooth and not as loud as I thought. In fact, I think it's quieter than my B&S 8000w portable.
Be aware that without the 4 wheel-kit, it will take some sort of overhead lift to move this thing. Even with the wheels, on anything other than flat, hard surface, it will almost require 2 people to move it. Built like a tank but at almost 400lbs it's heavy like a tank too.
