Setup, Compatibility & Care
Before initial use, fully charge the Ultra2 using the included USB-C cable to ensure the battery is calibrated. The digital display will indicate 100% when ready. To maintain performance, regularly unscrew and clean the removable rear net to prevent lint or hair build-up, which can obstruct the honeycomb air intake. When using the power bank feature, ensure your charging cable is rated for 18W to achieve optimal fast-charging speeds. When storing the fan for long periods, keep it in a cool, dry place and ensure the safety lock is engaged to prevent unintended activation.
