GENKINS GK2300i

Review

The GENKIS GK2300i is a 79cc 4-stroke OHV gasoline-powered portable inverter generator. It is designed for various uses, including tailgating, camping, off-grid power supply, emergency backup, and more.

When we turn on the generator, it starts up in 5 seconds with a maximum of two pulls on the cord. It can run for 8 hours at 50% load on a 1.36-gallon fuel tank. 

The portable generator has an auto-start feature that will start up automatically when the ignition switch is turned on. You can use this generator anywhere, anytime, without worrying about running out of fuel or having any problems.

This generator has a good weight capacity of 51 lbs & dimensions of 21 x 11 x 19 inches, making it very light in weight while still being able to do its job well enough as efficiently as possible.

While checking its outlet, we were very surprised by the amount of power it was able to produce, especially with its small frame. It features AC outlets that are compatible with 120V NEMA 5-20R devices and a DC carport that can be used to charge 12V batteries.

When we checked how loud it was from 10 meters away, we found that it was 54 dB, which was a pleasant surprise. The low setting was also very quiet.

After an hour of operation, we connected an air conditioner unit of 10000 BTU. When the compressor turned on, it merely increased before adjusting down to a lower rpm.

PowerSmart PS5020

Review

If you are looking for a generator that is fully RV friendly then this generator will be perfect fit for your needs. It is lightweight, convenient and easy to use. It’s dimension is 20.9 x 13.8 x 19.9 inches.

This portable generator will work with most vehicles and can be used in different climate conditions. It has a large 1.05 gallon fuel tank, which makes it very convenient for long trips without having to refill the gas tank each time you go on the road.

Keep in mind that oil is not included with this item (some company does). When we get the item, we’ll put fresh oil in. For optimal performance and longevity, we recommend changing the oil after the first 10 hours of usage and again after 100 hours of operation. Every year you should replace spark plug.

The PowerSmart Generator can run up to 7 hours at 50% load. The PowerSmart Generator is a great way to have access to AC and USB outlets while on the go. This generator has two AC outlets (120V) and two USB-A ports (5V), as well as a DC car port (12V). The PowerSmart Generator is perfect for camping, tailgating, or any other time when you need to be able to charge your devices.

After 7.5 hours of running, we see that it still had a quarter of a tank. It has a harmonic distortion of less than 1.2%. While checking the generator we couldn’t hear any sound from 65 feet away. It is the super quietest generator.

Westinghouse iGen2500

Review

The Westinghouse iGen2500 inverter generator is a very popular model. It s small and lightweight, making it easy to transport and move around. It’s weight is 46 lbs. The Westinghouse iGen2500 is useful for a wide range of applications because to its flexibility to run on both gasoline and liquid propane. 

Because of its parallel capabilities, Westinghouse is superior. While testing in our lab, we connect an AC of 10,000 BTU in parallel connection. It works well. We recommend this generator for people who lives in places like where the power goes out frequently!

The motor inside the Westinghouse iGen2500 is a powerful 98cc 60 Hz 5500 RPM unit. The Westinghouse generator operates on gasoline and produces 2500 peak watts and 2200 operating watts. It has AC outlets for duplex 120V 20A (5-20R) and DC outlets for 2x 5V USB port (USB-A). Plus, it’s relatively quiet and easy to operate.

When we’re testing this generator, it’s very quiet. We can’t hear it even when we’re standing right next to it while cranking the engine. The noise level is similar to a Honda EU2000i generator. You have to change spark plug, air filter every year or after 300 hours of operation for better performance

The generator has a handle which is easy to carry. It’s not heavy at all. We can easily move it around with our hands. We also like the fact that the battery can be charged while we’re using the generator. The charging process is very fast too!

It is one of the most long-lasting & eco friendly generator on our list. At a load time of fifty percent, we discovered in our lab that it operates for 8.5 hours. In addition to this, it is equipped with a spark arrestor, which makes it appropriate for use while camping in a forest/wooded region.
