Gaiatop Portable Quiet Desk Fan, 6000mAh w/ RGB Ring (Blue) – $12 after code YFSDNYFT (was $20.98, limited time deal $28.99 list) · 4.4/5 · 882 ratings · 100+ bought in past month

Rechargeable battery desk fan with a 6000mAh cell that runs 6–18 hours per charge (recharges in ~5 hrs). Doubles as a power bank (USB 5V/1A output) to top off your phone or tablet. Five speed settings (35dB quiet operation), 90° tilt head, LED display showing speed and battery, plus a soft RGB ring that cycles through 7 colors. Compact at 5.6" wide. Also in Peach Pink and Silver.

Reviews are strong — people are repeatedly surprised how much air it moves for its size, and the quiet operation gets praised even at higher speeds. The 6000mAh battery is a favorite feature (one reviewer ran it all night and still had 60–65% left in the morning), and the power-bank function comes in handy for outages or working away from an outlet. The RGB ring also doubles nicely as a bedside nightlight.

Fair caveats: a couple reviewers note battery drains faster on higher speeds, so if you run it on max in hot weather you'll get well under the 18-hour claim. One reviewer's unit broke after 2 uses and couldn't return it without the original box (worth holding onto the packaging). Also note: there's an older USB-powered version floating around that has no battery — this listing is the rechargeable 6000mAh model, so make sure you're getting the right one.

Code YFSDNYFT brings it to $12 — solid value for a fan/power bank/nightlight combo.
