Does it blow cold air?
No cold air! Core cooling is contact-based via the semiconductor plate. Press against skin (e.g., face/neck/forehead); chills to 5.9°C (42.8°F) in 5s, drawing heat directly. Fan airflow (8m/s) disperses surface heat.
Can I use the fan while it's charging?
Yes! This fan fully supports simultaneous charging and usage. Additionally, when the fan is using its reverse charging feature (powering devices like phones), it can still operate normally and provide airflow without affecting your experience.
How long does ice-cooling last?
3-6 hrs (cooling + max fan). Fan only: 25hrs (low)/5hrs (high).
Must I reset speed each time?
No! Automatically remembers your last speed setting (1-100 stepless levels) at startup.
Can it charge phones?
Yes! 6800mAh battery acts as a power bank, using included C-C cable for 15W PD fast charging. When battery drops to 8%, reverse charging stops automatically to preserve core fan function. The fan continues operating normally until fully depleted.
