Our take on the Westinghouse iGen4500 3700W/4500W Gas Inverter Generator

The Westinghouse iGen4500 is a portable inverter generator rated at 3700 running watts and 4500 peak watts. It runs on gasoline from a 3.4-gallon tank and can run up to 18 hours at low load, with variable engine speed matching output to demand. Total harmonic distortion stays under 3%, so it can run laptops, TVs and other sensitive electronics. Push-button and wireless remote start plus a wheeled suitcase-style frame make it easier to move and start than open-frame generators. It suits campers, tailgaters and homeowners who want quiet backup power for a few appliances, though it is heavier and louder under load than smaller inverter units.

About the Westinghouse iGen4500 3700W/4500W Gas Inverter Generator

The Westinghouse iGen4500DF is a dual fuel inverter generator that runs on gasoline or propane (LPG). It produces 4500 peak watts and 3700 running watts. Variable engine speed produces only the power needed at a given time, which gives 30% to 50% higher fuel efficiency than a traditional generator. It runs up to 18 hours on a 3.4-gallon gas tank.

Outlets include a TT-30R RV Ready outlet, two 20A household outlets, and built-in USB ports. Total harmonic distortion is under 3%, so it can power sensitive electronics such as LCD/plasma televisions, laptops, tablets and mobile devices. A double-insulated acoustic enclosure, asymmetrical cooling fans and low tone mufflers keep noise as low as 52 dBA.

The generator starts with a push button or a key fob remote. An LED Data Center shows runtime, remaining fuel, load/output, volts and lifetime hours. The compact design has never-flat wheels and a telescoping, suitcase-style handle. Each unit is functionally tested at the factory and may contain a minimal amount of residual oil or fuel odor.

Questions and answers

Will it run an RV air conditioner?
A 13,500 BTU RV air conditioner usually needs a soft-start kit to run on this generator. Smaller loads like lights, a fridge and a TV run comfortably.
Can I use it for home backup?
Yes, through its TT-30R and household outlets for essentials like a fridge, furnace fan and lights. It is not a whole-home solution and should be connected with a proper transfer setup.
How loud is it?
It is quiet at low load, but noise rises as demand increases. Owners say it is quieter than open-frame generators but not silent under heavy draw.
Does it run on propane?
This iGen4500 model runs on gasoline only. Westinghouse sells a separate dual fuel version for propane use.
What maintenance does it need?
Regular oil changes, spark plug checks and fresh fuel with stabilizer for storage. Follow the break-in oil change in the manual.
