Review on 🌀 viniper Small Rechargeable Desk Fan - Long Lasting Operation up to 8-24 Hours, 3 Speeds, 180° Rotation - Battery Powered & USB Desk Fan - Portable, Small yet Powerful for Home/Office/Travel - Blue by Ingrid Buell

We love these little fans! I keep mine low all night while I sleep (8-10 hours) and it still works when I wake up. I only charge it when it dies, so I wake up the next night and charge it. It also charges quickly, I'd say around 4 hours. It is very quiet and also emits a lot of cool air. The middle one works all night but turns off early in the morning, and the top one turns off somewhere at night. Bought one for the office and a few more for our wedding in June as they last so we have a few available for our guests (it's hot in Louisiana in June lol)
