Verdict

The JUNG AIR TK04 is a 3-in-1 portable air conditioner delivering 9,000 BTU (2.6 kW) of cooling power using eco-friendly R290 refrigerant, making it suitable for rooms up to 25 square meters. Operating under Energy Efficiency Class A with a 1,000W power consumption and an EER of 2.6, this versatile device also functions as a dehumidifier (extracting 1.0 liter per hour) and a fan with an air circulation rate of 350 m³/h. Key advantages include an easy-to-use 24-hour timer, a dedicated remote control, a 0.5-liter internal condensation tank with a permanent drainage connection, and high mobility provided by integrated rollers, handles, and a window installation kit. However, its primary drawbacks are a relatively high maximum noise level of up to 65 dBA, which can be disruptive in quiet settings or bedrooms, and the space and layout limitations imposed by its required 1.5-meter single exhaust hose.
