Könner & Söhnen KS 4500i Inverter Generator 4,2 kW 230V

The KS 4500i inverter generator delivers clean, stable power for sensitive electronics, thanks to its pure sine wave output. Unlike conventional generators, it adjusts engine speed to the load, reducing fuel consumption and noise while extending runtime. With a maximum output of 4.2 kW and a rated output of 3.8 kW, it is suitable for camping, outdoor events, or as a backup power source at home.

Highlights

• Pure sine wave inverter technology for safe operation of sensitive devices
• Powerful 4-stroke OHV engine with 7.5 HP and 223 cm³ displacement
• Long runtime: up to 10.5 hours at 50% load on a 13 L fuel tank
• Multiple output options: 2x 230V AC sockets, 12V DC, and 2 USB ports
• Parallel capability for doubling power output (requires optional kit)
• LED display for voltage, frequency, and operating hours

In daily use

The KS 4500i starts easily with a recoil starter and runs quietly at just 66 dB(A) from 7 meters. Its low oil shutdown and overload protection safeguard the engine and connected devices. The compact design and built-in handle make it portable, while the fuel gauge lets you monitor remaining fuel at a glance.
