Westinghouse iGen2500 Review – Silent Inverter Generator

Normally I return the generator or sell it after testing and gathering enough information for my review, but Westinghouse iGen2500 is one of fewer portable inverter generators that I keep and use for myself.

Westinghouse iGen2500 is one of the highest-sold and most popular portable inverter generators for outdoor use on the market because it packs a whopping 2200 running watts in a tiny body.

We have compiled this Westinghouse iGen2500 review based on our noise, load, and runtime test, its efficiency, portability, convenience, budget, reliability, and popularity.

Westinghouse iGen2500 Review

Westinghouse iGen2500 inverter generator is made for recreational users. It is mostly used for camping, RV, and other outdoor activities, because it is easy to carry around thanks to the lightweight portable body, and it is a lot less noisy than a traditional generator.

Compared to iGen2200, iGen2500 has 400 extra running watts with better fuel efficiency despite being almost identical in weight and dimensions.

One of the main selling points of Westinghouse iGen2500 is clean power production. The harmonic distortion is less than 3% which allows us to plug power-sensitive devices such as phones, laptops, computers, and DSLR Cameras.

Furthermore, this machine also features automatic low-oil shutdown and overload protection like other Westinghouse models. These safety features protect the generator from internal friction and protect the appliances from sudden surges and the downfall of power due to overload.

A very good LED data center is installed on the control panel that shows the runtime of the engine (changes with the load), voltage, fuel levels, and power output.

I think it is a very convenient feature for the price point. We don’t have to purchase a separate volt-meter or a fuel gauge.

Westinghouse iGen2500 also features a parallel connection through which you can double the power by connecting another identical portable inverter generator of the same brand.

Large models are often expensive so having the option of connecting 2 same generators together is a convenient option.

Westinghouse iGen2500 is CARB compliant so it is free to use in the state of California. In addition, this machine is an EPA complaint too. It means this inverter generator is designed in such a way it will produce less environmental pollution.

I like the overall thin, compact, and portable suitcase type design. People who are so much into outdoor activities are very space-conscious because we have to carry a ton of things in a travel trailer.

Noise Test Of Westinghouse iGen2500 Portable Inverter Generator

It is a slightly larger unit than iGen2200 so it will be a bit noisy. I conducted a noise under the eco mode, and under load. The results are below.

On ECO-MODE:

  • 20 feet away, the noise was 60dB
  • 30 feet away, the noise was 57dB
  • 50 feet away, the noise was 53dB

Under load

  • 20 feet away, the noise was 69dB
  • 30 feet away, the noise was 67dB
  • 50 feet away, the noise was 61 dB

Load Test and runtime Of Westinghouse iGen2500 Generator

I would say expect 6 to 8 hours on a full tank of gas if you are using your travel trailer heavily if you are gonna run the AC, fireplace, hot water heater, microwave, and other stuff. So if you push to its limit, 6 to 8 hours is the maximum it will give.

Surprisingly, it ran our 15000 BTU AC unit. The voltage dropped when the compressor kicked in, then it reached back to 120V.

So I got a total power output of 2130 running watts, and 2460 peak watts out of the travel trailer. I was running my AC, some lights, and other small devices.

Running my 15000 BTU AC without any issues was the main selling point for me. It is such a big thing for a 48-pound generator.

What Can Westinghouse iGen2500 Portable Generator Run?

I have tested Westinghouse iGen2500 with the above-mentioned devices and it ran almost all of them without any issues. You just have to know the running and starting watts of the devices that you want to run, and if it fits in the range of Westinghouse iGen2500, it will surely run them.

Highlights And Main Selling Points

For the price, the Westinghouse iGen2500 portable generator packs a whopping 2200 running watts in a lightweight and super portable body. Even my girlfriend picks it up and throws it in the back of the trailer.

The fuel efficiency is just amazing. At 25% load, it will surely provide a 12-hour runtime or more. I normally push it to the limit by running some major appliances in my trailer including a 15000 BTU AC, and it normally gives 6 to 8 hours on a full tank.

Regarding maintenance, the oil draining tube is outside of the housing. Changing the oil and draining the fuel is both times taking processes, so making the draining easier is a small little detail that saves a lot of time.

Westinghouse iGen2500 produces safe and clean power with less than 3% harmonic distortion. Charge your power-sensitive devices like phones and laptops from the 2 USB outlets on the control directly without any issue.

Customer Reviews

Should You Buy Westinghouse iGen2500? My Verdict

If you are looking for a budget-friendly portable inverter generator for camping with decent enough power output and fuel efficiency, then Westinghouse iGen2500 is for you.

This machine provides more power output than iGen2200, it is super portable, parallel capable runs for 12 hours on 25% load, it can easily run a 15000 BTU AC with other small appliances, and is very quiet.

With a three-year limited warranty and decent customer service, Westinghouse iGen2500 is one of the best portable inverter generators on the market currently. I would recommend you buy this model.

  • CARB and EPA compliant
  • Not noisy at all
  • Less than 3% harmonic distortion
  • Excellent fuel-efficiency
  • Run our 15000 BTU AC without any problem

What I don’t

  • Didn’t find any.

I am a passionate environment engineer, who has been in the solar, and inverter generator industry for years. I have been a part of multiple safety and environment-related courses such as IOSH, Fire Safety, Solid Waste Management, etc. I have been installing solar plants for residential purposes since 2018.
