Best Inverter Generator In-depth Reviews 

1. Champion Power 100519 - Best for Open frame Inverter generator

Important specifications

  • Wattage: 6250 watts.

  • Item Dimensions (LxWxH): 26.6 x 25.6 x 23.7 

  • Item Weight: 121 Pounds.

  • Frequency: 60 Hz.

  • Runtime: 12 hours.

  • Fuel Type: Gasoline.

Product’s highlights

We can think of this best inverter generator as a hybrid because it is an Open Frame inverter generator. Companies often wrap their inverter generators with panels to reduce noise and enhance their appearance. 

The Champion 100519 is made into an open frame, but it is still an inverter generator. To add to that Digital Hybrid account, you can think of it as an Open Frame Digital Hybrid.

Today's Best Deals: View on Amazon

Pros

  • Bigger 4-liter fuel tank.

  • The touch controls are nicely located.

  • Eco-mode saves fuel.

  • Oil drain hose makes oil change more comfortable and clean.

  • Great warranty terms.

  • Consistent 9-60 Hz without worrying about damaging sensitive electronics.

Cons

  • A bit inconvenient when changing the oil.

Bottom line

It is the quiet generator for money and achievements. The Champion 100496 open frame standard transmitter has a noise level of 74 DBA. The translation of Champion 100519 Digital Hybrid is 69.0 DBA. 

According to a recent study on perceived noise levels, a measured level of 6 decibels would be half as loud. Therefore, Champion's statement is that the sound should be almost half as loud as the standard transmitter.

2. Westinghouse WGen3600 - Best for Electric devices

Important specifications

  • Wattage: 3600.

  • Item Dimensions (LxWxH): 23.3 x 22.8 x 21.3

  • Item Weight: 107 Pounds.

  • Color: Blue.

  • Fuel Type: Gasoline.

  • Tank Volume: 4 Gallons.

Product’s highlights

Delivering 3600 watts of running, the Westinghouse WGen3600 is a great generator to run a house in the event of an emergency. It also has 4650 watts of starting power, which is great for starting capacitors and starting ballasts at the same time. But keep in mind that if you run the refrigerator and AC at the same time, it is possible to trigger a circuit breaker.

Today’s Best Deals: View on Amazon

Pros

  • It has a three-year warranty.

  • It has good fuel efficiency.

  • Great customer service.

  • Reliable and durable.

  • Inexpensive.

Cons

  • Its battery doesn't last long.

Bottom line

It is quite similar to all other WGen models. It's protected by a sturdy steel frame, 1 inch in this case. The Westinghouse WGen3600 also comes with solid rubber feet on the front of the wheels for stability and slightly less vibration than the WGen3600v.

3. MAXOAK BLUETTI EB24 - Best for Solar energy

Important specifications

  • Wattage: 1000 watts.

  • Item Dimensions (LxWxH): 19.4 x 6.5 x 14.4

  • Voltage: 110 Volts.

  • Frequency: 60 Hz.

  • Output Wattage: 1000 Watts.

Product’s highlights

Battery-powered portable generators are more popular than ever. Luckily, Maxoak, a company that specializes in portable power supplies, has been developing some of the best and most affordable battery stations. This is one of the top-rated solar generators in all inverter generator reviews.

As a quick introduction, the EB240 is a suitcase power bank that has a frequency range of 2400Wh and provides 1000W of output power. This power is enough to run almost anything in your house, even the power drill.

Today’s Best Deals: View on Amazon

Pros

  • It has a lot of power to use.

  • The AC outlet is particularly easy to use.

  • Easier to hold.

FAQs

1. How many watts do I need in a generator?

You can run your most important home appliances with generators ranging from 3,500 to 7,500 watts. These include things like well pumps, refrigerators and freezers, and lighting circuits. That is the average generator size for house.

A generator with about 7500 watts running can run all of these devices at the same time. However, if you only want to use the generator to run essential power tools such as communication vehicles or TVs. You only need about 2,000 - 4,000 watts. For RVs, a 3000 - 4000 watt generator would be ideal.

2. How do you determine the generator size you need? 

Identify the device you want to power. Check the product owner's manual to determine how much power the appliance needs to run. Multiply the running power of the device by three. Add the running capacity to the starting capacity for the total power the unit needs to operate.

The total power of all small appliances, tools, and bulbs operated at the same time. Most devices have a label that shows wattage (if volts and amps are given: volts x amps = power (VA) times power factor). 

To learn more about which size a generator calculator, review the table above to make a reasonable choice.

3. How much generator wattage do I need to run my stove?

A 2000 watt generator can power a 500-watt deep freezer and one element of an electric stove. Or you could run the freezer, cook with a 650-watt microwave (1000 watt use), and a few lights. Even better is to use a slow cooker (300 watts), while an electric grill will use 1700 watts of generator power.

4. Can an inverter generator run a refrigerator?

The best inverter generator is an electrical device that converts DC battery power into household 120-volt AC power to run appliances such as refrigerators. Inverters come in a variety of capacities and some are powerful enough to operate a refrigerator.

5. Are inverter generators better than regular generators?

The inverter generates stable and reliable power regardless of motor speed. The power generated by an inverter generator is much “cleaner” than the power generated by a conventional generator. This power supply is roughly the same quality as the electricity normally supplied by your utility company.


Conclusion

Once equipped with the best inverter generator, you will be assured that you always have a reserve of energy. It will make all your emergency situations a lot lighter and more comfortable.
