Könner & Söhnen KS 4000iEG S — versatile power working for you

The upgraded Könner & Söhnen KS 4000iEG S inverter generator is designed for those who value independence, quiet operation, and efficiency in any conditions. This model runs on both gasoline and gas — providing the user with fuel choice, cost reduction, and stable performance. With up to 4.0 kW of power, it can safely supply sensitive electronics — laptops, TVs, heating boilers, medical equipment, or workshop tools, as the inverter technology with a true sine wave guarantees clean energy without risk to devices.

The enclosed noise-reducing housing lowers the sound level to 66 dB, making the KS 4000iEG S an ideal solution for private homes, camping, or mobile businesses. Thanks to the eco mode and a 13 L fuel tank, the generator operates for over 7 hours at 50% load. The advanced multifunctional LED display shows all important parameters, and for maximum convenience, it features 230 V sockets, a 12 V DC output, USB ports for charging gadgets, and the option to connect two generators in parallel for increased power. Wheels and a convenient handle allow easy transportation by one person. A hose with a reducer for gas connection is already included — everything is ready to use out of the box.
