Review on 💨 75mm USB Fan by GDSTIME - Powerful 75mm x 15mm Blower Fan for Efficient Cooling, 5V DC Brushless Cooling Fan by Doug Hawkins

I use this fan for the perhaps unusual purpose of bringing fresh air into my bedroom even when the door is closed at night. The fan is so small that I can just put it next to the exit door under the door gap and it will blow the stale air out of my room all night (I have a vent on the other side where the air enters). Such a small fan but it keeps the air clean and fresh. Since it's USB powered, finding a small charger to power it was very easy.
