Review on 🌀 ARCTIC Breeze Mobile - Mini USB Desktop Fan with Flexible Neck, Portable Desk Fan for Home & Office, Silent USB Fan, Fan Speed: 1700 RPM - White by Brian Page

Bought 24 for my class. My students use Chromebooks and plug this thing straight into the USB port, tilt it towards them, and there's enough airflow that you at least feel like you're cooling off. I had to stop them from sticking their fingers into the USB port. Blades they didn't cut. I warned them all to be careful with each one and they put it back in the storage box. The packaging is good for storage. The cord isn't very long, but it's definitely long enough to lay on a classroom table and lean over to students who report "enough" power. It also doesn't drain the Chromebook's battery. Win for this teacher!
