The KSB 21i S inverter generator offers the perfect balance of quiet operation, portability, and stable power for modern users. With a rated output of 1.8 kW (max. 2.0 kW) and a pure sine wave output, it provides safe energy for sensitive electronic devices — laptops, routers, TVs, or medical equipment. Its quiet housing design ensures just 62 dB at a distance of 7 m, making it comfortable for use in campsites, gardens, or residential areas without excessive noise. The lightweight 21 kg body with a sturdy top handle allows one-person transport. Equipped with a 4 L fuel tank and Eco mode, the generator reduces engine speed according to the load, extending runtime from a single fill and minimizing fuel consumption. The engine, manufactured under strict European standards, ensures reliable start and stable power supply. Safety and convenience are integrated into the design: low-oil and operating status indicators, an AC Reset button, and a DC fuse ensure safe operation for the user and connected appliances. Two 230 V AC sockets and a 12 V DC outlet allow convenient connection of multiple devices simultaneously. The parallel connection port enables connecting several generators for increased power — a scalable solution for higher energy needs. Complying with EURO 5 standard and supported by the European K&S service network, this inverter generator combines silence, precision, and practicality — an ideal assistant for camping, backup power, or outdoor work.
