On the lowest speed setting, the 4000mAh battery can provide several hours of continuous operation. Higher gear settings will consume more power, reducing runtime accordingly. The LED digital display lets you monitor battery level at all times so you're never caught off guard.\u003c\/p\u003e\n\u003ch4\u003eQ: Can both fan heads be adjusted independently?\u003c\/h4\u003e\n\u003cp\u003eA: The two heads share the same 90° automatic left-and-right oscillation driven by the motor. The vertical tilt (90° up and down) is adjusted manually, allowing you to angle the airflow up or down to suit your comfort. Together, they deliver comprehensive air coverage across your space.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I clean the Himist double head desktop fan?\u003c\/h4\u003e\n\u003cp\u003eA: The fan features a detachable front cover, making cleaning straightforward. Simply remove the cover, wipe or rinse the blades, allow everything to dry fully, then reattach the cover before use. Regular cleaning helps maintain optimal airflow performance.\u003c\/p\u003e\n\u003ch4\u003eQ: Does this fan work while it's plugged in and charging?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The fan can operate while connected to a USB power source (5V, 2A), so you can use it continuously with a USB charger or power bank even when the internal battery is low — perfect for desk use near a USB port.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
