Product details & service

What makes this product stand out?

This portable air conditioner needs no installation — set it up, run the exhaust hose to the window, switch it on. The advantage lies in flexibility: no drilling, no specialist installer, no intervention in the building fabric. If you rent, this design is hard to avoid. Performance data: 14,000 BTU, 4,100 watts, designed for rooms up to 45 m². A note on setup: the exhaust hose should run as short and straight as possible to the outside, and the window should stay sealed. Otherwise, exactly the warm air the unit just pushed out flows straight back in — and cooling performance drops noticeably. Also on board: App and Wi-Fi control.

  • ✓ Portable air conditioner
  • ✓ 14,000 BTU cooling capacity
