The multi-functional Tristar AC-5477 doesn't only cool, but also ventilates and dehumidifies the air. If you select the fan function, it'll provide a refreshing breeze without cooling the air. With its A energy label, the 780-watts portable air conditioner is very energy-efficient. Use the timer so the appliance activates and deactivates itself. Thanks to the wheels, you can easily move the portable air conditioner to any room. Don't want to use the timer? You can just as easily use the included remote control and operate the appliance from the comfort of your chair.
