Marketing says you can use the heater function by using the exhaust end, but I believe that gives less control over the flow rate.
Be careful to tip it properly so the moisture capturing pan doesn't overflow or leak elsewhere. Tip more backwards in direction of the drain pipe. This ensures any humidity removed from the air is dealt with properly.
Includes 1 battery capable of both powering the AC night mode for a few hours and providing charging for a phone.
Used for 1 summer season on and off. It kept my 12x15 bedroom cooled properly despite being so compact. Dual pipe means during fire season you won't get smoke in your house unlike the single pipe units out there.
This is also good for RV and camping. Has a built in flashlight.
