The Ultima Portable AC has a somewhat cube-shaped design that measures around 200mm around the edges. Up front, it has a grille from which cold air is blown into the room. The grille is made of plastic and is fully adjustable to direct the airflow where required. In fact, the whole body of the Ultima AC is made of plastic which helps keep the weight down. Move to the top and then there’s the opening to the water tank in the centre which can be used to fill in water. As mentioned earlier, this device requires water as part of its cooling process so it’s a good thing the refilling point is in a convenient location. Next to that, are some buttons that turn on/off the Ultima AC and control the fan speed. Coming towards the back, there’s a rotating strap that can be rolled back when not in use. When it is required, it can be rolled up and it can be used to carry the Ultima AC around or hang it anywhere. This makes it different from most other portable ACs as they don’t have it.
