Review on 🌀 Liwin Portable Air Conditioner Fan for Room Office Home - 4-in-1 Evaporative Personal Cooler, Humidifier, Desk Mist Fan - 3 Wind Speeds, 7 Color Atmosphere Lights by Michael Cooper

Popular for personal use. The fan is powerful but a bit noisy at maximum speed. It always needs to be powered by a PD cable to turn it on, which means it's non-rechargeable. But I have a 10000mah power supply that I used recently and I was able to use this portable fan at medium speed for about 2 hours and my power supply still had more juice, about 40%. As for cooling, it's understandable that it relies entirely on the mist from its humidifier, which can't match AC technology. But it's definitely cooler than regular fans. Adding ice to water has a slightly greater effect on cooling. About 550 ml of water was enough for me to spray continuously for 5 hours, which is enough for deep sleep. As an alternative night light and humidifier for the winter.
