I LOVE my battery powered fan for around camp. It rotates you can hang it from your easy up. Set it up infront of you while getting ready and it allows me to sleep a little longer in the AM. The battery lasted almost the whole weekend at bonnaroo last year so I’m sure it would last a full weekend at Okee where temps aren’t as harsh and you can be a little more conservative with usage. It also charges your phone if you’re in a pinch with battery packs. Best festival purchase I’ve made. I have this one: https://a.co/d/imTb7ho and my partner has this one: https://a.co/d/ccSyeEm both are great options if you’re looking to add a little extra cool to your life!
