Odoland 30000mAh Camping Fan with LED Lantern, Rechargeable Battery Operated Oscillating Fan with Remote & Hook, Portable Tent Fan with Timer, 4 Speeds for Outdoor Camp RV Jobsite Power Outage, Green

I have a fan like this and it’s a god send. There’s different sizes, I have a smaller one and my partner has a big one. It lasts 2-3days depending on how much we use it, and it has a light and a battery pack for charging other things. If it dies we plug it into the car for a couple hours, but I’m looking into getting solar chargers to be more sustainable
