What we like about Kesser 9000 BTU

  • Efficient cooling performance for standard and medium-sized rooms
  • Versatile 4-in-1 multi-functionality including cooling, dehumidifying, ventilation, and sleep modes
  • Great value for money at an affordable entry-level price point
  • Intuitive controls with an integrated touch screen, remote control, and smartphone app compatibility
  • Easy to transport and position due to built-in 360-degree wheels and a compact design
  • Includes a comprehensive installation and window sealing kit

What we don't like about Kesser 9000 BTU

  • Operating noise level can be quite loud when running at maximum cooling power
  • The required exhaust hose limits placement flexibility and takes up window or floor space
  • Cooling capacity is limited to small or medium rooms and is less effective in very large spaces

Verdict

The Kesser 9000 BTU portable air conditioner is a versatile 4-in-1 climate control unit that offers cooling, dehumidification (1 L/h), ventilation, and a specialized night/sleep mode. It features a cooling capacity of 2.6 kW with a power consumption of 950W to 1005W, efficiently covering room sizes between 10 to 20 square meters utilizing ecological R290 refrigerant. Main characteristics and pros include a maximum air flow rate of up to 380 m³/h, Energy Efficiency Class A rating, an integrated 24-hour timer, dual dust filters, 360-degree wheels for easy mobility, a digital touch LED display, and an included remote control. However, notable cons include a relatively heavy weight of up to 28 kg, a max noise level reaching up to 65 dB which can be loud during peak operation, and the typical portable air conditioner drawback of requiring a complex window sealing kit installation for its exhaust hose.
