Portable aircond is so noisy.. if u can bear the machine sound, then its ok..

And if u just use it for a while like 4-6 hour i think it is ok

If more than that, its not good because the hot air produce by the device itself even though u got airvent cant cover much the hot air produce..

I got one of these device

And u need to have long tube to get the water that flow out from the portable aircond somewhere..

Hole or something..

Waste my money only buy this thing.. hehe
