Anker eufy is voluntarily recalling select batches of the T8340 Smart Sock sold globally from January 2023 through September 2026. In a select number of devices, a defect in the sock's adhesive can cause the top cover of the sensor to detach from the sensor itself and can cause a potential choking hazard.

The reason is insufficient adhesive coverage on the top cover of the sensor. This issue may lead to a decrease in bonding strength, which could eventually cause the top cover of the sensor to fall off.

Over the four years that the product was sold worldwide, Anker has not received any reports of injuries. Out of precaution, we have decided to initiate a voluntary recall of the relevant batches of the products, and we are conducting this recall in coordination with the regional regulators and following all applicable local safety and compliance guidelines.

If you have the T8340 Smart Sock, please stop using the device immediately until you determine whether your device is part of the recall. Go to the recall page to check whether your device is included in the recall. If your device is included, you can request a gift card or a full refund of your purchase.

*Sales started in January 2023, and the sales end date differs by country: Australia and New Zealand in July 2026; Europe in May 2026; the United States in June 2026; and Canada in September 2026.
