Humane has issued an urgent warning to owners of its Ai Pin device, instructing them to immediately cease using the charging case due to a potential fire safety hazard. The issue stems from an anomaly discovered with the battery cell within the case, prompting Humane to prioritize customer safety and discontinue use. Despite the inconvenience, Humane is providing two free months of its subscription service as compensation and actively seeking a replacement charging case supplier. The Ai Pin, Battery Booster, and charging pad remain unaffected by the issue.
