In a notice posted on the Consumer Product Safety Commission’s website, myCharge, also known as RFA Brands, of Birmingham, Michigan, said 567,000 chargers were affected.

The company said it was aware of 120 reports of overheating chargers, including two reports of residential fires that resulted in approximately $165,000 in property damage.

It said Costco also received 115 returns of portable chargers where customers complained of melting, expanding, smoking, fire, burning, exploding or sparking. There are no reports of injuries requiring medical attention, myCharge said.

Consumers should immediately stop using the recalled portable chargers and contact myCharge at 888-251-2026 or [email protected] to obtain a free replacement portable charger, the company says.
