A resident in Zhengzhou, Henan Province, used a 9.9-yuan charging cable purchased online. The cable was not unplugged in time, causing a fire in the early hours of the morning. The living room was filled with thick smoke. The fire department confirmed that the cause of the accident was that the cable’s flame retardant performance did not meet the standards.
Tests show that inferior cables take more than 120 seconds to self-extinguish (the national standard requires ≤ 60 seconds), and they rust severely in salt spray tests, indicating poor corrosion resistance.
2. Beside Technology Product Safety Crisis
There have been a total of 4,407 complaints on HeiMaoTousu, involving incidents such as power bank explosions and data cable burnout. In April 2025, 38,814 units of the BS-30KP365 model power banks were recalled due to overheating risks caused by raw material defects.
IV. Product Innovation and Market Trends
1. Baseus Unveils 100W “Universal Protocol Master”
The dual-port super charging cable supports Xiaomi’s private protocol, PD fast charging, etc. It intelligently allocates 70W and 30W power to two devices and is priced starting at 79 yuan. Made of anti-bend fiber material, it has passed 10,000 bend tests.
2. Commercialization of Waterproof Technology
Shenzhen Xiehecheng Electronics has obtained the patent for “Waterproof Data Cable”. By using a double protection mechanism of elastic clamping pieces and observation plates, it solves the problem of water ingress at the interface and has been applied in the steamy environment of BYD’s cafeteria.
3. Government Procurement of Low-Price Standard Products
The government of Yining City, Xinjiang, procured 15-meter green data cables at a unit price of less than 100 yuan. The order included multiple categories with a total price of 3,900 yuan, reflecting the cost sensitivity of the grassroots market to basic functions.
Core Contradictions in the Industry
Technology Upgrade vs. Low-Price Dilemma: Leading enterprises are betting on precise manufacturing processes (such as Yingtong’s 99% welding yield rate), but small and medium-sized manufacturers are still trapped in the “hundred-yuan order” price war in the grassroots market.
Expanding Safety Gap: Frequent fire accidents caused by substandard wires have forced the country to formulate new national standards for power banks, which are expected to include additional needle-puncture and compression tests.
The incident reveals that the industry is undergoing a transitional pain of coexistence between “patent breakthroughs”and “after-sales crises”. To break through the deadlock in the future, it is necessary to simultaneously enhance the precision of the process (such as the anti-bounce patent in cutting), the quality control standards (such as the flame retardant V-0 certification), and reconstruct the after-sales response system to avoid the collapse of trust caused by “repairs turning into scrapping”.
