best inverter generator 2021


As someone who enjoys camping and outdoor activities, I understand the importance of having a reliable source of power when out in the wilderness. That’s where inverter generators come in. Inverter generators provide a steady source of clean energy that is essential for powering up appliances and charging devices while on the go. In this article, I will be reviewing the top inverter generators in 2021 and comparing their features to help you make an informed decision before making a purchase.

I. Description of Top Inverter Generators in 2021:

1. Honda EU2200i Inverter Generator:
The Honda EU2200i is one of the best portable inverter generators that offers a maximum power output of 2200Watts. It is equipped with a quiet and fuel-efficient engine that can run for up to eight hours on a single tank of gas. It also features an eco-throttle system that adjusts the engine speed as per the power demand, which helps to save fuel and run-time.

2. WEN 56380i Super Quiet 3800-Watt Portable Inverter Generator:
The WEN 56380i is a powerful and compact inverter generator that offers a maximum power output of 3800Watts. This generator is equipped with a 212cc engine that is designed for efficiency and long-lasting performance. It is also equipped with a sophisticated muffler system that reduces the noise level to a whisper, making it an ideal choice for camping trips and outdoor adventures.

3. Yamaha EF2200iS Inverter Generator:
The Yamaha EF2200iS is a popular choice among outdoor enthusiasts because of its ultra-quiet operation and long-lasting performance. This inverter generator offers a maximum power output of 2200Watts and can run for up to ten hours on a single tank of gas. It also features a smart throttle system that automatically adjusts the engine speed as per the power demand, providing maximum fuel efficiency and run-time.

4. Westinghouse iGen4500 Super Quiet Portable Inverter Generator:
The Westinghouse iGen4500 is one of the largest inverter generators on the market, offering a maximum power output of 4500Watts. This generator packs a powerful punch with a 224cc engine that is designed for durability and efficiency. It is also equipped with a muffler system that reduces the noise level to a minimum, making it a perfect choice for outdoor activities.

II. Factors used in Selecting the Best Inverter Generators:

When selecting the best inverter generator, there are several factors to consider. These include:

1. Power Output:
The power output is an important factor to consider as it determines how much electrical energy the generator can produce. The more the power output, the more electrical appliances and devices it can power.

2. Fuel Capacity:
Fuel capacity is an essential factor to consider as it determines the amount of fuel the generator can hold. Generators with a higher fuel capacity are ideal for longer run-times.

3. Noise Level:
Noise level is a crucial factor to consider, especially for outdoor activities. An inverter generator that operates at a low noise level is more convenient and pleasant to use.

4. Portability:
Portability is another significant factor to consider, especially if you plan to move your generator around. A lightweight and compact generator will be easier to transport.

5. Runtime:
Runtime is important as it determines the number of hours the generator can run on a single tank of gas. A generator with longer run-time is ideal for longer outdoor trips.

III. Comparison of Top Inverter Generators:

In the table below, I have compared the four inverter generators based on the factors mentioned above.

| Generator Name | Power Output (Watts) | Fuel Capacity (Gallons) | Noise Level (dB) | Portability (Weight) | Runtime (Hours) |
