Anker says it’s recalling its 321 Power Bank (PowerCore 5K, model number A1112), citing a fire risk posed by a manufacturing defect. The 321 is a compact power bank with two ports — one for USB-C and one for USB-A. Anker says “only a small number” produced after March 2023 are affected, but it’s recalling all of them anyway.
