Wiher Table Fan Quiet, Rechargeable Desk Fan with Turbo Airflow, 100 Speeds, Digital Display, 90° Rotating, Small Battery Desktop Fans for Bedroom Home Office Travel, Black

I bought this fan for my trucker boyfriend. He burns hot all the time and I thought a rechargeable fan would be nice for his truck. I charged the fan, only took 2 hours for a full charge. I set the fan in my bedroom window and it worked really well at pulling in fresh air. The fan can be adjusted up and down, but only a couple inches. Its not bad. It produces a strong wind, not something you can have blowing in your face at the highest speed. Its very quiet, very solid build. The usb charging cable is nice and strong, about 8 inches long. I have the purple fan, its pretty, not too bright.
