The Chill Breeze AC is not an AC unit as they claim. The so-called portable AC unit, which was once called Chill Well, is a swamp cooler. I ordered 2 Chill Breeze AC units and the units I received were not battery-powered as advertised, but had to be plugged in to operate. In addition, they operated on "water curtains" which had to be filled with water and then placed in the freezer before inserting into the unit, rather than filling the unit with water as advertised.
The Chill Breeze AC Portable Air Conditioner
Once inserted in the unit, the frozen water curtains lasted only about 30 minutes before they needed replacement, & the cooling effect was not adequate. I called customer service for a return authorization and refund and was informed that I would not be refunded the return postage even though the product was not as advertised. I would not recommend purchasing Chill Breeze AC Portable Air Conditioner.
