The self-ignition crisis of power banks has escalated. 3C certificates of major battery manufacturers have all been revoked or suspended. Please conduct self-inspections of these products immediately.

Almost simultaneously, industry giant Anker Innovations was also affected. On June 20, Anker announced the voluntary recall of certain batches of basic-model power banks, approved by the Hunan Market Supervision Department, due to safety risks. The recalled models include A1642, A1647, A1652, A1680, A1681, A1689, and A1257, totaling over 710,000 units. Anker’s quality inspection revealed that certain batches of industry-standard cells from a supplier had unauthorized raw material changes, which could lead to diaphragm insulation failure after long-term cyclic use, potentially causing overheating or even combustion. Media reports indicate that the cells used in Anker’s recalled products were supplied by Amperes.

Additionally, there have been multiple cases of self-ignition in non-recalled power banks during normal use, such as explosions in a Guangxi university library and a fire in a Osaka, Japan guesthouse that caused ¥8,000 in floor damage. These incidents have plummeted consumer trust in power bank safety and laid bare the industry’s hidden risks.
