Since June, the power bank market has been rocked by issues stemming from battery cell suppliers. Major brands, including Romoss and Anker Innovation, have announced the recall of over 2 million power banks due to potential safety concerns. The root of the problem lies with supplier Amperex Technology, whose 70+ 3C certifications and ISO three-system certifications have been fully suspended. This incident underscores the hidden dangers within the power bank market's supply chain, underscoring the urgent need for stricter controls by manufacturers at the source and increased regulatory oversight to mitigate risks.
