Many products sold online and in stores may not meet safety standards and could increase your risk of fire.

When buying a product that uses a lithium-ion battery, take time to research it. Look for a stamp from a nationally recognized testing lab on the packaging and product, which means that it meets important safety standards.

To find out if a product has been tested by a nationally recognized testing laboratory (NRTL), look for a specific certification mark on the product, its packaging, or its documentation. NRTLs are independent organizations recognized by the Occupational Safety and Health Administration (OSHA) to certify products, particularly electrical equipment, for safety.

Common NRTL logos to look for:

• UL (Underwriters Laboratories): One of the most well-known NRTLs, the UL mark means a product has been tested to meet safety standards.

• ETL (Electrical Testing Laboratories): Issued by Intertek, the ETL Listed Mark signifies that a product is compliant with safety standards.

• CSA (Canadian Standards Association): A Canadian NRTL that also tests products for the U.S. market. A mark showing "C" and "US" indicates compliance with both Canadian and U.S. standard
