That charger you bought from Amazon may be dangerous!

260,000 AmazonBasics portable chargers are being recalled after reports that they can overheat and cause fires or burns.

The recall covers six versions of the AmazonBasics portable battery. The power banks, used to charge smartphones and other gadgets on the go, were sold at Amazon.com, Amazon book stores and Amazon pop-up shops between Dec. 2014 and July 2017. They cost between $9 and $40.
