Product Overview

I have recently had the opportunity to test out the GENMAX GM1200i Inverter Generator, and I must say that I am very impressed with its performance and features. This is a powerful inverter generator that offers 1200 starting watts and 1000 running watts of clean power, making it the ideal choice for powering small tools, lights, fans, and other sensitive electronics. It is also extremely lightweight at only 25.3 pounds, making it easy to transport from place to place.

The GENMAX GM1200i has a 57cc 4 stroke engine that is highly fuel efficient, offering up to 6.5 hours of run time on a 0.66 gallon gas tank when operating at 50 percent load. Additionally, it operates at a very quiet 58 dBA noise output when operating at 25 percent load and 23 feet away from the generator. This makes it an ideal choice for camping trips or other activities where you want to be able to enjoy the outdoors in peace and quiet without having a loud generator running in the background.

The power panel of the GENMAX GM1200i includes low oil alarm, overload alarm, CO warning light, output indicator and one 120V/20A outlet as well as one 5V/1A outlet and one 5V/2.1A outlet all of which can be used safely with sensitive electronics without damaging them. Additionally, this generator features a CO detect shutdown sensor which helps prevent carbon monoxide poisoning by automatically shutting down if dangerous levels of CO are detected in the air near the generator. To top it off, it comes with a 1 year warranty and lifetime technical support from experts so you can rest assured that you re getting a reliable product that will last you for years to come.

In conclusion, I believe that the GENMAX GM1200i Inverter Generator is an excellent choice for those who need an affordable yet powerful inverter generator that can provide clean power to their sensitive electronics while also being easy to transport due to its ultralight design. It is highly fuel efficient and operates at an impressively low noise level making it perfect for camping trips or any outdoor activity where you need some extra power but don t want to disturb your surroundings with a loud generator noise. Highly recommended!
