Review on ✨ Portable Desk and Table Fan, Battery Powered Fan with Adjustable Height and Foldable Design - Ideal Air Circulator Floor Fan for Outdoor Activities, Courtyard, Beach, Travel, Room - 4 Speeds, Timer, Night Light, Remote Control - Built-in 10800mAh Battery (Black) by Ashley Sexton

When the battery is getting low, the beep that sounds when the power is turned off will be faint, depending on the overall size of the item. It would be better if it just shuts down and doesn't squeak. The beeps that the remote makes when changing the settings are also too loud. I know this sounds like a crazy topic to write a review for, but for those who are light sleepers and use this fan for background noise, the beeping defeats the purpose. I like that it's easy to travel with. I'll try to leave it on battery power overnight.
