Review on 🌀 3-in-1 Portable Air Conditioner Fan with Mini Evaporative Cooling, Built-in Ice Tray, USB Power - Ideal for Home, Office, Dorm (White) by Andrea Young

Ice cube trays really cool the air. It only works in our trailer with a USB plug, so we don't have to turn on the generator to use it. We have a 160w solar panel that keeps the batteries charged while we work. Although it's a small room. You must sit directly in front of the device. It pushes cold air about 4 feet away from it. Doesn't fit in a larger space but is definitely great for a small space or a desk in an office. UPDATE: It stopped working after 9 uses.
