I recently brought this Geek Aire rechargeable 5 inch mini fan. I love the performance of the product. It is a rechargeable fan so there is no need for me to plug in all the time. I recharge with usb or power bank and I am able to carry it where ever I go. What I love the most is that the battery stays longer. During this summer season, this fan has helped me a lot and it is very affordable. So try it yourself and enjoy.
