The US Consumer Product Safety Commission says Amazon received 53 reports of the chargers overheating, including one of a customer who was burned by battery acid. There were also four reports of property damage due to fire and smoke.
The CPSC says customers should stop using the chargers and contact Amazon for a refund. Seattle-based Amazon.com says it is also contacting customers.
