It's a compact, energy-efficient alternative to traditional air conditioning for personal use.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What USB power source does this mini air cooler require?\u003c\/h4\u003e\n\u003cp\u003eA: The cooler is powered via a standard USB connection, making it compatible with laptops, desktop USB ports, USB wall adapters, and portable power banks.
