9 Best Inverter Generators Under $1000

What is the best inverter generator below $1000?

First off, why use an inverter generator rather than a conventional generator? For one, the newer and more technologically advanced inverter generators are much more fuel-efficient.

Thus, saving you money in the long run. Inverter generators are also much quieter and less annoying to be around. Lastly, we believe that inverter generators are typically a much better bang for the buck.

There are a plethora of reasons why people get a generator. Camping, traveling in an RV, tailgating, home back up, and off-grid living are a few examples. Before the creation of portable inverter generators, people thought owning a generator would be incredibly inconvenient. Luckily, owning an inverter generator in today’s day in age is relatively convenient, portable, and affordable.

Not only are they used for fun, but they come in serious handy in case of an emergency. It wasn’t until I had a family of my own until I decided to purchase my first inverter generator. Knowing that my family will have a working refrigerator and other power sources in a severe storm certainly gave me peace of mind.

Without further ado, based on experience, reviews, research, and comparisons; we gathered a list of the 9 best inverter generators under $1000.

1. Westinghouse iGen4500 (3700-4500 Watt)

Inverter Generators Under $1000

First up, the highly-rated Westinghouse iGen4500 is a great portable generator running below $1000. It is incredibly powerful, producing 3700-watts and a peak of 4500-watts. Coming with wheels, it is very convenient and easy to travel with for the weight of 104lbs.

The generator is powered by gas or propane. On a quarter load, you receive 18 hours of run time. However, in “efficient mode,” the Westinghouse iGen4500 is incredibly fuel-efficient. You get about 11 hours with only 1 gallon of gas. On the front, the display shows fuel amount, remaining run time, lifetime hours, power output, and voltage output. 

The Westinghouse iGen4500 inverter generator is extremely quiet, averaging 52-55dB. Something I like about the iGen4500 is the ability to run a midsized air conditioner of 15,000 BTU if needed. It’s effortless to hold a conversation next to it without the noise becoming too overbearing.

On the front, you will see two 5 volt USB ports for your laptop, tablets, phones, etc. Considering it produces nearly the highest amount of Watts for the price, it is also one of the largest inverter generators on the market.

It can be powered on by a push start, wireless start, or recoil if the battery dies. Many people who need a generator for their RV will benefit from this unit. On the front is a 30 amp receptacle ready to go. One of the few downsides is the many claims of Westinghouse’s poor customer service.

Overall, the Westinghouse iGen4500 is an outstanding generator running below $1000 for a plethora of reasons. It has exceptionally high voltage, very fuel-efficient, durable, very quiet, has an efficient mode, has incredible ratings, and is very reliable. We highly recommend it.
