  • Camping and tailgating buffs looking to enhance their experience

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Westinghouse iGen4500DF in use

The Westinghouse iGen4500DF

With its dual-fuel technology, the powerful and versatile Westinghouse iGen4500DF provides an output of 120V. While gasoline-powered, it gives a running wattage of 3,700W along with a peak wattage of 4,500W. While propane-powered, it provides 3,330 rated watts and 4,050 starting watts. In addition, the device is parallel capable (parallel cord (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added power.

The inverter generator has a low noise rating of 52 dBA (just slightly more noisy than a quiet suburb), which earned it a place in our 10 quietest portable generators. Its starting mechanisms include a conventional pull-start mechanism and a simple and elegant electric starter (battery included). Moreover, to offer you even more convenience, the iGen4500DF can also be remotely started (key fob included).

As for its running time, the iGen4500DF, along with its 3.4 gallons fuel capacity, can run for up to 18 hours with a full tank filled with gasoline (fuel consumption around 0.19 GPH). If propane is used, it can operate for up to 22 hours (on a 20 lbs tank - propane consumption around 0.21 GPH).

The iGen4500DF produces a clean sine wave: thanks to a <3% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.


The control panel features the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

Furthermore, it has 2 DC outlets: there's two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets.

This Westinghouse generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').


Thanks to its closed inverter generator design (L24.5 x W17.5 x H20 in), the Westinghouse iGen4500DF, is more esthetical than a typical, open frame generator. The generator has a contemporary design, convenient for recreationally generating power.

As the generator's weight is 104.7 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, this lack of maneuverability is compensated by its set of 2 wheels (⌀5.5") and its telecospic handle, with which you can conveniently shift it, once it's on the ground.


Panel of the Westinghouse iGen4500DF

The iGen4500DF's control panel

The control panel of the iGen4500DF includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the power output, fuel level, voltage, lifetime run hours and remaining run time.

In addition to this info, the device’s light indicators will display if the oil level is too low, the generator is ready and the generator is overloaded.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Westinghouse iGen4500DF also comes with some accessories: key fob, propane hose, oil, battery charger, tool kit and funnel are included. An official running cover and a suitable storage cover are also available, as separate purchases.


The Westinghouse iGen4500DF is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.

Product Videos

The Westinghouse iGen4500DF versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Westinghouse iGen4500DF compare to inverter generators of similar power (between 3500 and 4500 W).

  • At a weight of 104.7 pounds, the Westinghouse iGen4500DF places in the expected weight range of the inverter generators in the 3500-4500 rated wattage range. Regarding dry weight, one of the champions in the same power range is the Genmax GM4600iAEFIC, with a dry weight of only 58.4 lbs.
  • Since this inverter generator is rated for a lowest possible noise of 52 dBA, it can be considered as one of the most quiet of the products generating similar power.
  • Given that the iGen4500DF reaches an autonomy of up to 18 hours with a full tank and at 25% load, it is placed within the average autonomy range of similarly powerful inverter generators. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Firman W03661OF, boasting with up to 25 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. As this inverter generator uses an estimated 0.19 GPH (gallon per hour) at a 25% load, it finds itself in the average gasoline consumption range of similar products. If you wish to further improve in the area of fuel efficiency, the Champion 200988, which boasts with a gas consumption of only 0.16 GPH, may be the right generator for you.

Price comparison

As you can see from these interactive charts, when compared to other 3500-4500W dual fuel inverter generators, the Westinghouse iGen4500DF is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

I can't find a parallel kit made for the igen4500DF? (Asked October 13, 2019)

Westinghouse are still waiting for them. They are expected first quarter 2020.

Can you operate this inside of a RV generator compartment? (Asked March 13, 2021)

You probably can, as long as you are mindful of all safety aspects, and keep at least 3 feet of clearance on all sides of the generator, including overhead.

can you hook up an exhaust pipe to vent to the outside? (Asked April 23, 2021)

Absolutely not! You must always operate your generator outside, where there is enough airflow and ventilation. NEVER run a generator indoors. Carbon monoxide can kill you in minutes.

I live at 5000 feet elevation and sometimes camp above 8000 feet. Do I need to purchase a high altitude jet for this device? (Asked May 06, 2021)

It's absolutely recommended. Note that in addition to the high altitude carburetor kit, you'll also need to purchase a high altitude dual fuel regulator.

With propane as the fuel source, if you turn off the generator via the panel or using the remote fob does the propane continue to flow at some rate and cause an explosion hazard? Or does the generator have a propane control valve that stops the flow when the generator is not running? Having a remote start capability for a generator running on propane would seem pointless if the generator cannot stop the gas flow when necessary. (Asked August 14, 2021)

You would have to manually open/close your propane tank valve.

what is the advantage of the parallel ports. can this offer 240 volt operation with a 2nd generator? thank you (Asked November 22, 2021)

Paralleling 2 units will increase the maximum available current, but will have no effect on voltage.

    This generator works very well. We have been using it to power our camper for a year now. With air conditioner running there is plenty of power to spare. Starts easy, remote control is a big bonus. My only complaint it the noise level is not nearly as quiet as stated. Generators on this list with higher db ratings sound much quieter as we walk around the camp grounds and see what others are using.

    + PROS:
    • Good power. Easy to start and remote control
    - CONS:
    • Sounds louder than other brands of the same size

    Bought this the first one came damaged ordered a second one . It would not start call Westinghouse support center they immediately told me it is a caliber problem send it back . I like the feature that is has but. I am not willing to give it a third time ordering this

    + PROS:
    • Nice features
    - CONS:
    • Poorly made would not start the company knew immediately what was wrong with it . They have had issues with this model .

    I have or have owned a 20kw Kohler whole home, Yamaha 2400i, Champion 4500df and Duromax xp4500ih.
    The Westinghouse igen in my opinion is the best value for features received.
    It has electric start (Yamaha doesn’t)
    Independent ignition & fuel select (the Champion doesn’t) and full service drawings parts lists & schematics (the Duromax doesn’t)
    It has all the features important to properly use the product and the security of a complete parts list in the event repairs are needed.
    The gasoline capacity allows it it run all evening & thru the night and still running strong in mid morning. Some of the others can’t make it thru the night.
    It’s as quiet as as I’ve heard any brand.
    The only things I had to add was a quick connect on the propane and a drain hose to drain the oil. If those two items has been included originally I’d say it was the perfect mid sized inverter generator.
    We’ve had a couple multiple day outages so I’ve had a chance to see how well it functions firsthand, I’m pleased with my purchase.
    I use it as a backup to my Kohler 20kw when I want to economize on fuel.

    + PROS:
    • Price
    • Features
    • Fuel economy
    - CONS:
    • No oil drain tube
    • No propane quick connect

    I found the propane starting issue was a missing paper seal on the propane hose. Mine would not run or start well until I figured out the seal issue

    + PROS:
    • Good price.
    - CONS:
    • Quality was a bit sketchy. Seems they are manufacturing them too quickly. Quality control is lacking. Nothing bad, but the main cover didn't fit well and there was a rattle from the pull starter while running.

    My first try at this generator was a dismal failure. Would not start on propane or gasoline. On line support had me jump through several unproductive hoops that only served to increase my frustration. I won’t bore with all the details. I ended my saga with the first one by loading into my subcompact car and taking it back.
    One of the online “support” suggestions was because the oil level was near the top line the oil too full and that was why it wouldn’t start. For some silly reason I thought if I went ahead and complied with this obvious bs, we could get to actually addressing the problem. I will only say the oil change/drain on this generator could be designed better. When I explained previous attempts to start this generator the 3rd support person suggested I take it back where I bought it. While not addressing the problem this should have been the 1st thing recommended.

    After getting a refund I looked around and compared features of various generators. This model stood head and shoulders above the others. It had all the features my wife “suggested” when we discussed a generator. My 2nd try at this generator worked perfectly. We have close to 10 hours on the generator no problems so far.

    + PROS:
    • Difficult to find another generator offering all these features at this price
    • Extremely quiet
    • operates sensitive electronics. Has low THD
    • Dual fuel runs well on easy to store propane
    - CONS:
    • Quality control issues.
    • A crap shoot to get one that works
    • A real crap shoot to get support that is knowledgeable
    • Changing oil can be a messy nightmare

  6. 4.75

    This is a fantastic generator fully loaded with all the features and with enough stable power to handle virtually all 120V loads. It starts very easily on Propane with a push of the start button or remote, could not be simpler. It’s amazingly quiet, quieter than my 1700 watt 70cc enclosed inverter generator it’s replacing! I tested it up to about 27 amps of resistive load on propane and it handled it well with very little voltage drop (3V) and without skipping a beat as the load was applied. Excellent run times, I have it connected to two 40 pound tanks and it runs forever, actually have not run out yet. It’s well built, panels are fairly thick, and design is great.
    Only issue I had is it arrived with a cracked side panel and a dent in the shipping box. I tried calling the day of delivery, but the call kept dropping and I could not get through. The next business day I called again and got right through, the agent was very helpful and sent out a replacement side panel. I called again to check status and she was able to expedite it. I received it in about a week and a half after the first call, they also included some extra screws.
    One last thing they could improve is the oil drain, they have an extender so the oil drains out the provided hole, but it’s hard to get a tool on it and the extender will try to unscrew rather than the plug screw. I’d like to see a hose on it like some brands have, because if you spill oil it’s near impossible to get out of the frame or other holes – then it slowly leaks out over the next few days.
    I do recommend this generator!

    + PROS:
    • Very competitive price for features and power output.
    • Has all the features including dual fuel, automatic choke, and remote start. Top inverter output at 4500 watts peak, 3700 watts rated.
    • Fuel efficient, very quiet, small size & weight, easy to wheel around.
    • Good support most times.
    - CONS:
    • Can take on damage in shipping.
    • Sometimes the support line drops calls.

  7. 2

    Horrible. It’s never really worked right. First I had to put in an altitude kit. Then it still wouldn’t run on propane, so I had to get new regulator. Worked for awhile, but never would start right on propane. It would run rough, especially with any kind of load. Finally would run at all. I think I may have gotten a unit someone returned with about 30 hour s on it.

    It’s been in the shop now 2 1/2 months. Shop says Westinghouse is non-responsive to getting warranty parts. Called Westinghouse, you have to call them because they don’t seem to respond to email. The last guy was a little chippy telling me that I had to respond to an email they never sent to get approval to send it to the shop. I got a little upset. But the next day they did send an email acknowledging it was at the shop and that they had called the shop .

    + PROS:
    • When it was warm and running well it was good.
    - CONS:
    • Never started right on propane.
    • Ran rough under load.
    • Quit running.
    • Service/support hasn't been very good.
