dont buy portable
you will 200% regret it
Second this.
1) Noisy
2) Electricity guzzler. More so that normal aircon.
3) Can never cool the room enough. When it expels hot air from the room through the exhaust pipe, new warm air from outside will be drawn in from crevices, and the aircon has to cool these newly drawn in air again. It will forever play catch up, machiam like a boat with holes and water flooding in. No matter how much u scoop the water out, new water will keep coming in.
And dun bother with evaporative air cooler too. Too expensive for too little cooling effect. Makes ur room humid.
If u die die wan to get a portable aircon, consider the coolzy series which u treat more as a cold fan, rather than an aircon.
