Anker already recalled 1.1 million power banks last month, and now it is casting a wider net by adding more models to the list.

The PowerCore 10000, MagGo Power Bank and Zolo Power Bank are part of a global recall issued by Anker.

Anker, the electronics manufacturer, has issued another major recall — this time involving five of its most popular charging devices. It’s the second recall the company has announced this month, affecting more than one million power banks so far, with more potentially to come. Anker says the move is being made “out of an abundance of caution.”
