It seems that Blast AC, which claimed to be a portable AC unit but is a swamp cooler, has changed its name from Blaux Portable AC. I ordered 2 Blaux Portable AC units in 2020 and it took 2 months for delivery. The units 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 Blast Auxiliary Portable AC
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 Blast Portable AC, which seems to be the same product branded under a different name.
