Core Viewpoint - The series of safety incidents involving power banks, particularly the Romoss brand, highlights systemic issues within the entire industry, not just isolated brand failures [1][2]. Industry Issues - The power bank industry has a low technical barrier to entry, leading to a proliferation of participants, including many white-label manufacturers [1][2]. - Price competition is fierce, with consumers prioritizing cost and charging speed over brand loyalty, resulting in a market where products are often sold at unsustainable prices [2][3]. - The average cost of a quality power bank can reach 60 yuan, while products priced below 50 yuan struggle to maintain reasonable profit margins [2]. Production and Supply Chain - Most power bank brands do not own production lines and instead adopt a "light asset model," outsourcing manufacturing to reduce costs and risks [3][5]. - This outsourcing can lead to quality control issues, as brands push for lower costs, prompting manufacturers to cut corners [3][5]. - The cost of battery cells, which can account for over half of a power bank's total cost, is a primary focus for cost reduction, with some manufacturers using recycled or substandard materials that pose safety risks [3][5]. Regulatory Environment - The introduction of 3C certification for mobile power supplies aims to improve safety standards, but many brands still face challenges in compliance [6][7]. - The previous certification process allowed for potential manipulation, as companies could selectively send samples for testing, leading to discrepancies between tested and mass-produced products [6][7]. - The new certification method involves on-site sampling during production, which is expected to raise quality standards and increase the risk of brand elimination for those lacking comprehensive quality control [7].
