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.”

The Anker Power Bank models A1257 and A1647, the Anker MagGo Power Bank model A1652, and the Anker Zolo Power Bank models A1681 and A1689 all potentially have faulty cells. If you have one, Anker says to stop using it immediately, even if it looks fine, because there's a risk of overheating, melting, smoke, or catching fire.
