Why safety certification for USB chargers matters
An uncertified charger can fail on insulation, temperature, or emissions. Certification is the paper trail that a unit was tested against a published standard. For buyers that trail is what customs, retailers, and insurers ask to see.
FUMEI’s source pages state that products are made to meet international standards and name CE, FCC, and RoHS. The FAQ adds that the team can work with you on the marks required for your market. Ask for the report that matches the SKU and the destination before you book the vessel.
