OtterBox’s OtterSpot stackable wi-fi charging battery packs had been launched in August 2019, and now the corporate shared that early items might swell “under multi-stack and higher temperature conditions.” That’s a major downside as a result of stacking these batteries to recharge them is core to OtterBox’s pitch for the product. The firm at present presents a bundle containing a 36W charging base with one battery, however the base can concurrently cost as much as two stackable batteries, plus a Qi-compatible gadget on prime.

OtterBox spokesperson Julie Campagnoli shared with The Verge that this challenge impacts items that had been manufactured throughout the first two months of manufacturing, between July by way of August 2019. No accidents have been reported as of but.

Regardless of when you will have bought the OtterSpot, it’s a good suggestion to verify the serial quantity on the underside of every battery. OtterBox says that affected battery serial numbers start with 229, 250, and 259.

OtterBox has kicked off a voluntary substitute program for the OtterSpot, and it’ll change batteries without charge if you happen to name its customer support line at 1-855-688-7269. This info is situated on the backside of OtterBox’s support page, which I’ve taken a screenshot of under. The firm claims that it has despatched a message to clients who bought an early unit, however I wouldn’t wait on a message in case your serial quantity is a kind of affected by this defect.

The firm advised The Verge that it had a restricted distribution of OtterSpot at launch and that retailers that at present supply the product (Apple, Adorama, to call a pair) wouldn’t have had any of those early, probably faulty merchandise to promote.
