After its reputation went up in flames, Humane warns users its charging case may too

If the wave of overwhelmingly negative reviews weren’t enough, it seems that Humane has discovered yet another major issue with its once-hyped AI Pin. The company is warning customers not to use the device’s charging case due to a potential “fire safety risk.”

In an email sent to AI Pin owners, the company said it had received a report of a “charging issue” that led to “a quality issue with the battery cell supplied by a third-party vendor used in your Charge Case Accessory.” Humane didn’t explicitly indicate whether the unspecified “charging issue” caused an actual fire, but it said an investigation found that “certain battery cells supplied by this vendor may pose a fire safety risk.”

While Humane is so far not using the word “recall,” the company is advising people to stop using the charging case immediately. Other charging accessories, including the battery booster and charge pad, are apparently safe as their batteries come from different suppliers. We’ve reached out to Humane for more information and whether they have plans to refund or replace the $149 accessory for people who have already bought one. In the meantime, the company is offering customers two months of its subscription service for free.
