Westinghouse iGen2500
Pros
- User manual is well written
- It’s very fuel efficient
- Best value for money
Cons
- No electric start
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. 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.
It has a very low noise level of 52 dB. 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.

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 inverter 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.
