Best 4000 Watt Inverter Generator

With the cost of gas going up  month after month and power outage being something common, it’s important to invest in alternative power backup options that won’t increase the cost of living.

Solar power may be an option, but that energy can only last so much. Standard generators can power your devices when power is gone. But it’s an expensive affair.

Inverter generators are the best solution. And the 4000 watts models provides just enough starting power required to power up and run your devices.

The 4000 watts inverter generators aren’t just lighter. They are also fuel efficient, especially because they automatically adjust thee engine to produce only the power that a particular application requires. More importantly, these devices guarantee high quality power output, which is more reliable as the power you get from your usual outlets.

With that said, below is a review of some of the best 4000 watts inverter generators that you should get right now if you live in a place prone to regular power shortages.

Best 4000-Watts Inverter Generator Review

1. Westinghouse iGen4500 Portable Inverter Generator

Power failure can ruin your work schedule, an outdoors event, or an indoor party. It gets even worse when home appliances are off and if your phone doesn’t have power.

But if you invest in the Westinghouse iGen4500 portable inverter generator, you can stop worrying about power failures and keep your appliances running so that you can get the most important things done.

Powerful enough to fuel an RV and quieter than many similar generators, the iGen4500 is ideal for use even in a space full of people who don’t appreciate the noise level of standard generators.

The iGen4500 is a gas-powered model, with a tank that can hold up to 3.4 gallons of fuel. Once fully loaded with gas, iGen4500 will run for 18 hours before craving for another fuel load. While it runs at 3,700 watts, the power can reach somewhere between 4000 and 4500 watts.

Westinghouse iGen4500 is easy to start. You just have to push a button or use a remote control to ignite. Because it includes a TT-30R 30 AMP RV outlet, you won’t need additional adapters to connect it to a standard RV.

The LCD display is something you won’t see in many standard generators. So its integration to this model is definitely a plus. The display plays a very important role of letting you know how much fuel the generator used, the current power output, voltage, as well as runtime.

When it comes to performance, Westinghouse iGen4500 produces clean electric wave at a Total Harmonic Distortion of less than 3%. That’s why it works well even with small electronic devices such as personal computers, cell phones and televisions.

Speaking of noise levels, the Westinghouse iGen4500 operates at the lowest value possible. It doesn’t exceed 53 decibels, and therefore it should be perfect to use in an environment full of people who don’t appreciate a lot of noise.

This isn’t a heavy inverter generator and it isn’t the lightest either. At 93 pounds, Westinghouse iGen4500 isn’t a machine that you can move from place to place on your own. It does have portable wheels, a telescoping handle, and a top handle for mobility. But you’ll need help to lift it up if you want to put it onto an elevated spot.

Pros

  • Easy to start and run and has a good runtime
  • Quiet; its noise level stands at 53 decibels
  • Comes with a dedicated RV outlet

Cons

  • It’s too heavy to carry on your own
  • It can be quite costly for some people 

2. Champion 4000-Watt RV Ready Inverter Generator

Whether you want to power your RV or you need the best inverter generator to power and run household electronics in the event of power outage, you may want to consider the Champion 400 watts RV Ready Inverter Generator.

There’s a lot to love about the Champion 4000 Watts RV Ready Inverter Generator.

This generator’s 2.9 gallons tank is easy to empty and add oil. It gives you clean sinew wave power at less than 3% Total Harmonic Distortion, which makes it perfect for power sensitive appliances such as televisions, smartphones, and personal computers. And it features a Quick Touch Panel with easy to use controls for navigation.

What is converter in electronics

The 292cc engine of Champion inverter generator can control overload, especially if there’s a higher wattage demand in the economy mode.

On a full tank, the Champion inverter generator can run up to 17 hours on standard mode, giving you enough time to power and run your appliances. Also, it can run up to 24 hours on economic mode, so your devices stay on when power outage mockingly glares at you for an extended period.

Champion inverter generator features a built-in oil level sensor that keeps the engine in check, turning it off when the level drops low to protect the engine from damages.

Apparently, this isn’t such a quiet inverter generator. The sound level is at 64 decibels from about 23 feet away, which is louder than a group of people chanting loudly. Even so, we don’t think that the noise can be annoying or deafening. After all, it’s power you need the most, and therefore sometime you won’t mind the noise.

One thing about this inverter generator’s noise level is that it depends on the mode you choose, with the economy setting being quieter than the electrical mode.

Where are sportsman generators made

While it may not be a necessary feature to have on an inverter generator per say, the Champion inverter generator even gives you the option to connect another inverter to it via the parallel kit, especially if you need more sinew wave power. If you have another similar generator and connect the two to one another, you’ll get up to 8,000 watts of starting power. 

Champion is not a lightweight inverter generator. With the 2.9 gallons tank full, expect it to weigh around 91 pounds. It does have transportation wheels, but you may need assistance if you want to lift it to an elevated surface.

3. WEN GN400i RV-Ready 4000-Watt Open Frame Inverter Generator

If you’re in the market for an open frame generator with a peak power output of 4000 watts and a running power of 3500 watts, you might want to consider the WEN GN400i.

In our eyes, and based on multiple rounds of testing and hundreds of reviews online, this model is not only reliable and solid, it’s also the most affordable model in the market. So when it comes to performance and cost, this gizmo will give you the absolute best of both worlds.

WEN GN400i is a gas-powered inverter generator with a fuel tank of capacity 1.85 gallons. At just 50% load, you can get up to 7 hours runtime, with the full tank giving you nearly 14 hours of runtime. Simply put, you get sufficient energy to power your devices as you wait for power to come back.

While this inverter generator is a reliable model that many gas powered machines, we do wish it were somewhat quieter. Its noise levels stand at 67db. While the noise level isn’t as deafening, people who prefer lower noise levels may not vote in its favor. At least the noise level won’t go up at a higher load, so that’s an advantage to having this machine powering up your appliances.

Noise level aside, WEN GN400i is the most lightweight model in its class, weighing just 70.5 pounds total. It doesn’t have transportation wheels, but at least the metal handles on the left and right can make it easy to lift when you have a helping hand from someone.

Perhaps another good thing about this inverter generator is that you can run it in parallel with a similar unit, usually if you need more starting power. If you do so, you get up to 8000 watts of starting power at your disposal. 

Pros

  • A lightweight inverter generate that shouldn’t be difficult to move around
  • Gives you clean sinew power
  • It’s an ideal model for running power sensitive appliances
  • Includes a parallel cable for connecting to similar machine if you need more power

Cons

  • Small gas tank
  • We wish it included an economy mode to lengthen the runtime
  • This thing can be quite louder even when it’s not on full load

Conclusion

Because inverter generators are more fuel-efficient than standard generators, they are the best option to consider when you need a power backup that you can use when there’s power outage.

In addition to saving you on the cost of fuel, these generators provide clean sinew power, so you can use them to power even the most power sensitive appliances in your home or on a campground.
