9 Best Inverter Generators In 2024

Inverter generators are a big step forward in providing power that’s portable, efficient, and clean. They’re different from old generators because they give a steady power output that’s safe for sensitive electronics like laptops, phones, and medical equipment. This is because they can change AC power to DC, then back to a cleaner AC. They’re really useful for camping, outdoor activities, emergencies at home, or any time you need reliable power away from regular sources.

Here are a few things to consider:

  • Power Output: Choose an inverter generator with 2000 to 3000 watts for medium power needs. For higher power, go for generators up to 4500 watts.
  • Runtime: Look for generators that can run for 5-6 hours on one tank of fuel. Some generators can run up to 22 hours, perfect for long outages.
  • Fuel Type: Consider fuel efficiency and availability when selecting a generator. Most use gasoline but prioritize options that are easy to fuel and keep running smoothly.

You can choose the best inverter generators by focusing on these factors. This will help improve your power efficiency.

Buying Guide For The Best Inverter Generators

Going for an inverter generator over other types of generators is quite a good decision as they are more portable and quiet. However, finding the best suitable one for yourself in the market is at all an easy task as there are plenty of good options available out there.

Well, this can be done easily if you know how to compare the options properly. That being said, we have come up with this buying guide where we will discuss all the important facts related to inverter generators so you can pick one for yourself from our list easily.

1. Power Output

While looking out for an inverter generator option, the most important thing that you should pay attention to is the power output. There are two kinds of power output ratings mentioned usually, starting watts and running watts.

While the running watts is the amount of power that the generator provides consistently. The starting watts are slightly extra power that the generator offers for about the initial 2-3 seconds to get the motor-based home appliances running. So, if the collective power requirement of all the appliances that you want to run is around 3000 Watts, you should get a generator that is capable of offering 3000 Watts or more consistent power.

2. Running Time

The runtime of an inverter generator tells you about the total time the generator can provide power when the tank capacity is one full. In case you want an inverter generator that you can take out with you for camping and picnics, you should go for the one that is efficient enough to last for a long time. Otherwise, if you want a portable generator option for home use, you can go with any option that you like.

3. Fuel Type

Most of the inverter generator options that are available in the market use gasoline as the fuel. That is why we have only picked the gasoline-powered generator options to include on our list. However, if you want a different generator, you can also look out for inverter generator options that operate on propane or natural gas. Yes, there are such options available too, so you can check them out and compare them with other options to pick the best one.

4. Tank Capacity

As inverter generators are one of the portable kinds of generator options. The runtime of the inverter generators depends on the size of their fuel tank. To make the generator portable, brands tend to make the tank smaller. Thus, you should definitely take this into consideration while looking for a new inverter generator. A bigger tank capacity will allow you to fill in more fuel, which will eventually allow you to use the generator for a longer duration.

5. Outlets

As the inverter generators are highly portable, people generally prefer them to be used outdoors while camping. That being said, you must know that most of the inverter generators come with outlets that you can use to directly plug in any appliances, or even use them to charge your mobile phones or laptops via the charger. In that case, it’s always better to have multiple outlets available on the inverter generator so you can plug in various appliances and devices at the same time.

6. Parallel Capacity

You will come across several inverter generator options featuring the parallel capacity feature. This feature or ability of the inverter generator allows you to use multiple generators connected to each other to obtain a much higher power output. Therefore, if you have a friend who owns a similar inverter generator, it’s possible to connect them to each other and can enjoy increased power output.

7. Warranty

Apart from checking the general features and specifications, you must also pay attention to the warranty information of the inverter generator that you decide to purchase. In most cases, you will find at least a 1 year of warranty or longer as almost all the popular brands commonly provide it. In case the brand is not offering any warranty for their inverter generator, we would recommend you to drop that option and look for other better ones.

Conclusion

Inverter generators are reliable and efficient for backup power. They are small, fuel-efficient, and provide steady power, making them a popular choice for portable and quiet energy needs. These generators continue to improve, becoming essential for both recreational and professional purposes.
