Anker is recalling 1.1 million power banks—including the popular PowerCore 10000—due to fire and explosion risks. If you own one of the affected models, you can get a free replacement. This is part of four ongoing recalls for Anker’s portable chargers.

Editor’s Note: If you rely on an Anker power bank, check if yours is on the recall list—these things aren’t just glitchy, they’re dangerous. Battery fires are no joke, and with portable chargers being everywhere these days, this recall is a big deal for travelers, commuters, and anyone who uses one daily. Better safe than scorched.
