It’s getting harder and harder not to view the Humane AI Pin as destined to go down as one of tech’s all-time stinkers and cautionary tales. After reviews questioning why it existed, returns that outpaced its sales and a warning that its Charge Case could pose a “fire safety risk,” the company is now recalling the latter. The issue stems from the case’s battery cells, supplied by a third-party vendor, which could overheat and cause a fire hazard.

Humane posted on Thursday that it’s conducting the voluntary recall “out of an abundance of caution.” The startup says its charging case is the only accessory affected — not the battery booster, charging pad or Pin itself. “The issue is isolated to battery cells used in the Charge Case Accessory,” Humane wrote. “It is not related to its hardware design.”

The company says one of its battery suppliers is to blame. “Our investigation determined that the battery supplier was no longer meeting our quality standards and that battery cells supplied by this vendor can pose a fire risk,” Humane wrote. The company says it’s severed ties with the supplier and is currently evaluating a new one.

In fairness to Humane, the recall was (in its words) the result of only one incident where a user plugged it into a third-party USB-C cable and power source. It hasn’t received reports of injuries or damage. As easy as it is to poke fun at an overhyped company’s other shoe dropping, at least it’s informing consumers and conducting the recall voluntarily rather than trying to bury it for the sake of PR. Perhaps Humane can look to Samsung for inspiration on rebounding from a product that catches on fire — and not in a good way.

The Consumer Product Safety Commission (CPSC) posted a blurb about the recall with more detail. It says consumers who bought the Charge Case separately will receive a $149 refund. Those who got the case as part of the Humane AI Pin Complete System will get $129 back. In addition, Humane will supply replacement charging cases, but don’t expect them anytime soon: The estimated wait is three to six months. The CPSC says about 10,500 units are affected.

Humane advises charge case owners to “dispose of the product in accordance with any local and state laws” rather than chucking it in the trash. Presumably, that’s to avoid a real dumpster fire to match the metaphorical one at Humane.
