Due to a series of electronic product fire incidents, on September 24, 2017, relevant U.S. departments issued laws specifically targeting e-commerce, requiring Amazon to notify overseas e-commerce sellers on its platform to provide relevant safety compliance reports. Amazon must order merchants to stop selling if they do not submit test reports conforming to UL standards. The test reports must be qualified reports issued by laboratories recognized by ISO17025/ILAC ISO17025 standards. China JJR has the relevant qualifications and provides related testing services. Feel free to request a quote.

Therefore, as the safety test for jump starters, only electronic products that pass the UL2743 certification test can continue to be sold on Amazon.
