Review on 🌬️ Upgrade 5 in 1 Personal Space Water Fans - Portable Mini Air Conditioner USB Fan for Desktop, Nightstand, Office, Dorm by Chris Drury

So far this block is working like a champ in the hottest summer ever. I wouldn't have survived this summer without this "mobile air conditioner". Fill it with ice water and this block will cool the air a few feet away. Ideal next to your computer or TV, powered by USB cable. The fan is quiet and powerful compared to an older model purchased a few years ago. I might consider another one next summer when it's as hot as it is now. Highly recommended.
