Westinghouse iPro4200 Portable Generator Review

Westinghouse iPro4200 is a dependable power source for job sites. It is an open frame inverter generator that is different from the regular inverter style units. It has a powerful engine, which delivers impressive output power. It is easy to install and quite safe to use because of having GFCI-protected outlets. Also, iPro4200 is extremely fuel-efficient.

Generator Type: Westinghouse iPro4200 is a gasoline-fueled inverter generator specially designed for industrial applications. But it can also be used during power outages at homes or for camping and tailgating. It is a hybrid generator, which means it is an inverter but in a traditional non-inverter generator’s skin. It is more fuel-efficient and 50% quieter than a conventional generator.

Design: Its steel, open frame design makes it a durable generator that can withstand the toughest job site environments.

Portability: It doesn’t come with wheels, but it is a portable unit. Its open-frame design and 82 pounds weight make it easy for two people to move it around the construction site. Also, it is not a bulky unit. It is only 20.5 inches wide, 24 inches in length, and 20 inches high.

Certification: Westinghouse iPro4200 is not only EPA (Environmental Protection Agency) certified and CARB (California Air Resources Board) approved, but also meet the standards set by OSHA (Occupational Safety and Health Administration).

You can use this inverter in all the 50 states of America. Also, its OSHA certification ensures that the employees’ health and safety are at a top priority.

Output Power: It is made with a 212cc, 5.8 HP, 4-stroke Westinghouse OHV engine. This powerful engine produces 4200 starting watts and 3500 running watts. This power is enough to run multiple power tools at a construction site or big and small appliances at home or during outdoor trips.

Clean Power: This iPro4200 is an inverter generator, so it produces clean and reliable power. It has a THD (Total Harmonic Distortion) rating of less than 3%. This minimal distortion rating in electrical power allows users to charge their sensitive electronic items without worrying about damages. Sensitive electronics include cell phones, gaming systems, laptops, computers, and more.

Parallel Capable: It is not a parallel capable unit, so you cannot link it to another iPro4200 to increase the output power.

Tank Size and Runtime: A 2.6-gallon steel fuel tank with a fuel gauge allows the generator to work up to 18 hours at quarter load and 15 hours at half load. This excellent runtime will give peace of mind to the contractors.

Efficiency Mode: Westinghouse iPro4200 has a built-in efficiency mode that allows the engine to increase or decreases its speed according to the load. This variable engine speed makes the generator 30% to 50% more fuel-efficient than the traditional units. Also, the efficiency mode prolongs engine life and reduces exhaust emissions.

Starting Mechanism: Only features a recoil (pull-start) mechanism.

Noise Level: It is a noisy unit with a decibel rating of 62 dBA, but its noise level is still lower than many conventional generators.

Power Receptacles: The control panel of iPro4200 includes both AC and DC power outlets. The complete power panel is GFCI (Ground Fault Circuit Interrupter) protected to give users a safe environment to work at a job site. These GFCI outlets turn off the current supply when they detect an abnormal activity between the outgoing and incoming current. It protects the users from electric shocks caused due to short circuits or insulation failure.

There are six 120 Volt 20 Ampere (5-20R) AC outlets and two 5 Volt USB ports.

With AC receptacles, you can run your power tools or home appliances. And USB ports will charge your USB-powered devices.

Light Indicators:

You will be notified by the indicator lights when the oil level gets too low.

The generator gets overloaded.

The generator gets ready to provide output.

Data Center: The VFT data center is also part of the control panel. It displays the operational voltage, frequency, and total runtime of the generator. This information helps track maintenance intervals.

Safety: For generator safety, we have automatic low-oil shutdown and overload protection.

Overloading causes the generator to heat up. So, overload protection safeguards the unit from this overheating that can damage both your unit and appliances.

An automatic low-oil shutdown turns off the generator when there is less oil remaining.

Warranty: Westinghouse iPro4200 is backed by a 3-year limited residential warranty and a 1-year limited commercial warranty. Not all generator parts are covered under warranty. Also, it offers lifetime technical support that will help users a lot in the long run.

Westinghouse iPro4200 vs. Champion 100302 vs. Generac GP3500iO

My Opinion:

Pros: Westinghouse iPro4200 is a powerful inverter generator. It is tough and durable, highly fuel-efficient, and produces clean power. It is a lightweight machine, operates without creating much noise, and has a data center that displays real-time performance information of the generator.

Cons: There is no electric start mechanism. Also, it doesn’t have 30 Ampere and 12 Volt outlets.


What other things iPro4200 generator box include?

Along with the iPro4200 inverter generator, its box includes a manual, one 10W-30 oil bottle of 0.6 quarts, a funnel, spark plug socket wrench, and a warranty card.

Does this generator come with a spark arrestor?

Yes, Westinghouse iPro4200 does come with a spark arrestor. It is an essential safety feature as it allows the generator to run at job sites and campgrounds safely. The spark arrestor arrests sparks and doesn’t let them come out of the engine during operation.

How many gallons of gasoline does it consume per hour?

Westinghouse iPro4200 is quite a fuel-efficient inverter generator. It consumes around 0.14 gallons of gasoline per hour.
