Review on 🌬️ Portable Desk and Table Fan: Foldable Standing Fan with Telescopic Pedestal, Ultra-Quiet, 4-Speed Settings, Perfect for Bedroom, Office, Fishing, Camping - 7200mAh Battery by Kimberly Johnson

This fan worked well for the first three days of my trip. That was until there was nearly 100 and wet af. Now it runs about 10 minutes at a time. I think it's because it's just draining the battery (which doesn't seem to want to be charged anymore). Nowhere in the listing or documentation does it say it won't run on USB power (why not?). I can't figure out what the other port is for either, but it certainly doesn't charge it. If this could run over USB or longer than 10 minutes that would be great. In this form, the fan is practically useless.
