Generac Power Systems 5940 Details and Specifications

Generac Portable Model 5940

Power the fun stuff or cover an emergency with a GP Series portable generator. Affordable reliability and features not usually found on basic portable models make these a favorite for home use, camping, job sites or outdoor events. This electric start model includes a plug-in battery charger jack to keep the battery charged and ready to go.

Reliability From the Start
Because of Generac’s focus on power generation, we know how to design an engine that can stand up to the long hours of continuous use generators can be required to run. Cast iron cylinders add longevity, not found on every portable generator engine.

Easily Accessible Controls
A portable generator needs to be ready for use at all times. Generac added maintenance reminders on the hour meter, so scheduled maintenance is easy to track, and the convenient fuel gauge provides at-a-glance fuel monitoring. Many portable models have controls located in inconvenient locations and are difficult to access quickly, especially in the dark. We gave control placement careful consideration, with comprehensive control sets conveniently located for easy access.

Framed for Durability
The hardened steel frame gives our portable generator cradles added strength and are a premium 1¼” thick, a full ¼” thicker in diameter than competitors' models. The addition of integrated brackets and impact resistant corners on most models gives contractors rugged options ideal for job site use.

Emissions: EPA/49 State, not for sale to California

Includes: Product Literature, SAE 30 Oil and Wheel Kit

  1. Great Generator

    Posted by Unknown on 31st Aug 2011

    We had this unit for two years and had no problem starting and running. Power a well, septic pump, Refrig, and living room. I would recomend this to anyone!

  2. Great back up generator

    Posted by Dave Dennison on 18th Apr 2011

    I own this exact model. A person should read the safety and operating info.first! Important stuff. This unit starts very well,but it takes some muscle to turn it over quickly to start it. Runs all appliances well,one caveat use common sense don't start or run too many at a time.
    We heat water with gas,don't have an electric stove but do have a well pump (220). This unit does not have clean enough power to run sensitive electronic equipment! That said,it's well worth the money! I recommend it.
