Water from the 380ml tank is drawn through a cooling pad; as the fan pulls warm air through the wet pad, evaporation lowers the air temperature, delivering a noticeably cooler and slightly humidified breeze to your personal space — similar in principle to how sweating cools the body.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How long does the 380ml water tank last on a single fill?\u003c\/h4\u003e\n\u003cp\u003eA: The water tank provides approximately 3 to 8 hours of continuous cooling per fill. The exact duration depends on your selected fan speed and the ambient humidity in your environment — drier conditions mean faster evaporation and shorter run times, while more humid environments extend the tank life.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What do I need to power this portable desktop fan?\u003c\/h4\u003e\n\u003cp\u003eA: The cooler runs on DC 5V USB power (0.2A–1.4A, consuming just 1W–5W). You can plug it into any standard USB port — including a laptop, desktop computer, USB wall adapter, or USB power bank — making it extremely versatile and energy-efficient.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the USB air cooler suitable for use while sleeping?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! On the lowest speed setting the unit operates at just 30 dB — quieter than a whisper — making it ideal for bedroom use. The built-in warm night light also adds a gentle ambient glow without being disruptive, helping you stay cool and comfortable through the night.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"How does the USB desktop air cooler cool the air?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This portable air cooler uses evaporative water-cooling technology.
