Should I get a corded USB fan or a rechargeable battery fan?

Corded USB-A or USB-C fans like the Honeywell HT-904 or Koonie tend to push more air per dollar because they don't carry battery cost. Rechargeable models like the Warmco or KIMMOO are better for travel, cars, or sleeping in a bed away from outlets. Specialist subreddits flag that cheap rechargeables often have weaker airflow and shorter real-world battery life than their listings claim.
