WHATOOK Small Desk Fan Personal Fans: 5000mah 25 Hours Battery Office Quiet Mini Desktop Fan Portable Rechargeable Travel Essentials (Purple, 5000 mAh)

I got this one. 4 other front end people have similar. USB-C rechargeable, I usually keep it under 10% power and a charge lasts 3-4 shifts. At out store (post remodel), the WIC booklet is in the plastic boxes with the protection plan booklets, and the stand/handle on the back fits perfectly on the WIC booklet to hold the fan at head/neck level. fan
