KOONIE 4 Inch USB Small Desk Fan - Powerful Airflow, 3 Speed Settings, 40° Adjustable Head, Ultra Quiet Personal Fan for Office, Home & Travel - Perfect for Desktop, Bedside & Workspace Cooling

I got this little fan to take to conventions and to use on my desk. I wasn’t expecting much power honestly. This exceeded my expectations. Great power and the cord is a great length. Super happy with this purchase.Great fan for work! Very quiet and moves a lot of air! :)Good little fan but for some reason the low setting randomly shuts off. It’s annoying having to adjust but works fine for the other. Great airflow for how small it is. Seller has reached out fast and sent new one no issues. Well worth the money.Very good value and surprisingly good performance.We like it, very convenient to move it around.Excelente por el precio, buena velocidad de aire para lo pequeño que es. No coge mucho espacio en el escritorio. Y facil de cargar.This little fan is powerful. Worth the money. I used it for work and it helped so much when I was hot.It’s a very powerful small desktop fan. Moves a lot more air than the last fan I had and it’s very quiet.On the lowest setting, it's very quiet while still moving a considerable amount of air. During a heat wave power outage, I had this on my bedside table, powered by a Jackery power bank. It kept my wife and myself cool enough to be comfortable, and drew very little power from the battery bank. The high setting is quite strong and also a bit louder, but not unpleasant! I would buy this item again!Really great little fan. Not sure why, but I find it works better than any other fan i've ever used. It might be cause the front is actually flat rather than curved. I am always hot and usually have the air conditioner on al the time or i'm dying of heat. I found that if I use this fan and direct it towards my face, it helps keep me cool without needing to use the air conditioner. The reason I was trying to find a fan even though I have an air conditioner is because the air conditioner costs a lot in electric, and it makes noise so if i'm making calls to clients when i'm working from home, the air conditioner makes a bit of noise in the background, whereas with the fan, I just need to point it towards my face but in a way that it doesn't make windy sounds into the speaker of the phone, so it works pretty good, i'm impressed enough that i'm writing a review about a desk fan, lol.Its a wonderful light weight desk fan that only need power via 5v usb cable (cable attached to the fan ) fan has three airflow mode ; which can be selected via single press able button . I personally using it my old mobile charger (v5 1amp ). It’s already more than a week am using it. Will update it more in future…Perfect
