Amazon is re-calling six styles of portable battery chargers after complaints they’ve caught fire and caused chemical burns.

The chargers are branded as “Amazon Basics” with that logo on the front of the unit.

In a release today Amazon states it has received 53 reports of the power banks overheating in the U.S, including one report of chemical burns due to “contact with battery acid” and four reports of property damage.

The recalled chargers were sold on from December 2014-July 2017 and cost between $9 and $40.

If you have one of these chargers Amazon urges you to unplug it and stop using them immediately and contact Amazon for instructions on how to return them. Amazon says you will receive a full-refund.
