The following is quoted from the website:

3-Second Rapid All-Around Heating The HAGOOGI rechargeable hand warmer is equipped with a carbon crystal heating element, so there's no need to wait for warmth – it starts heating in just 3 seconds! Unlike conventional products that heat both sides but not the center, the HAGOOGI electric hand warmer uses a cylindrical shape for 360° all-around heating, cutting through the cold more efficiently and comprehensively.
3-Level Temperature Adjustment Press and hold the button for 3 seconds. When the red light turns on, it enters hand warmer mode, making operation simple. It also features temperature adjustment, allowing you to select the appropriate temperature from three levels: low, medium, and high. Please note: To prevent low-temperature burns, do not use the electric hand warmer on the same body part for extended periods in high-temperature mode.
2-in-1 Mobile Battery Function Equipped with a large-capacity 10,000mAh (5,000mAh x2) battery, the rechargeable hand warmer offers operating times of approximately 7-14 hours in low mode, 5-7 hours in medium mode, and 4-6 hours in high mode (this is the combined usage time for both hand warmers).
