Maybach 25kva generator The Maybach 25kva generator is a powerful and versatile machine that is perfect for a variety of applications. It is powered by a single-cylinder, four-stroke engine that produces 25 kilowatts of power, making it ideal for backing up homes, businesses, and even industrial facilities. The generator is also air-cooled, which means that it does not require any water or coolant to operate, making it a more convenient and portable option than liquid-cooled generators.
