Chinanews.com, January 12th (China News Finance reporter Xie Yiguan) The reporter learned from the China Consumers Association that recently, the China Consumers Association conducted a comparative test on some brands of charging data lines sold in the market and found that among the 46 samples, nearly half of the samples were resistance The combustion ability is not good, the bending resistance of 9 samples is poor, and the ports of 13 samples are deformed under pressure.
According to the China Consumers Association, these samples were purchased by the staff of the Consumers Association from multiple e-commerce platforms, all claiming to support fast charging.
Among the 46 samples, 7 samples did not indicate the brand name, 6 of which only had simple packaging and no sales packaging; 10 did not clearly indicate the production implementation standards.

Nearly half of the samples have poor flame retardancy
When the charging data line is used at high power, once an abnormality occurs, whether it is self-overheating that causes spontaneous combustion to become an ignition source, or being close to a fire-catching object becomes a combustion-supporting source, or even itself produces molten droplets during the combustion process and causes other objects to catch fire , will bring harm to personal and property safety.
The comparative test results show that all samples meet the requirements of withstand voltage and insulation resistance before the test, but nearly half of the samples have poor flame retardancy, especially the sheath of braided wires is more likely to reduce flame retardancy.
The samples that failed in the flame retardant performance test involved brands such as Pinsheng and Xiaomi.

26% of samples had unsatisfactory pressure drop test results
The greater the voltage drop, the greater the power loss, the lower the charging rate, and even cause the data line to heat up, causing a safety hazard.
The comparative test results show that 26% of the samples have unsatisfactory pressure drop test results.
Among the 46 samples, 34 samples have a voltage drop lower than 750 millivolts, 12 samples have a voltage drop higher than 750 millivolts, and 7 of them have a voltage drop higher than 1000 millivolts. The price is only 2.14 yuan. The nominal brand is " The maximum voltage drop of the data line of Ankeyou/Terafeng is as high as 2310 millivolts.

The performance of plugging and unplugging of 8 sample interfaces is not good
In daily use, due to the frequent plugging and unplugging of charging data cables and mobile communication terminal interfaces such as mobile phones, the interface is prone to damage, resulting in charging failure or other safety problems.
The comparison test results show that more than 80% of the samples have passed the plug-in test, performed well, and can still be used normally after the test and meet the withstand voltage and insulation requirements.
However, the pull-out force of 5 samples exceeds the limit (the pull-out force of the data cable interface should be kept within a certain value range, otherwise the interface will be too tight or too loose, and the mobile device will be damaged if it is too tight, and it will cause poor contact or short circuit), involving samples with nominal brands such as Anker (model A8432), TAFIQ (model TFK001), Baseus (model CAMRD-B01), Lulian (model US155), Olaison (model MS-PD020), etc.
After the plug-in test, there were still 3 samples that failed the verification of the withstand voltage test, indicating that the performance was damaged and could not be used normally, and the plug-in durability was not good.
It involves 3 samples whose nominal brands are vivo (model BK-C-19), Pinsheng (model TC-FC-1000), and CHIJIE (model HWSJX01).

21 samples have weak corrosion resistance
The charging data cable has been exposed to the air for a long time. If the exposed metal part has poor corrosion resistance, the conductive path may be disconnected due to corrosion, and the charging cable may fail. It may also be due to the corrosion of the pins resulting in excessive resistance, which may cause the charging interface to overheat during the charging process. , there are hidden dangers such as burning the interface.
According to the China Consumers Association, after a 24-hour salt spray test, it was found that 25 samples had good salt spray performance and good corrosion resistance; The sheath fell off due to fog corrosion; 2 samples lost the charging function.
After the salt spray test, 2 samples failed the withstand voltage test verification, and 1 sample failed the insulation resistance test verification.

9 samples have poor bending resistance
In daily use, the part where the charging data cable is connected to mobile communication terminals such as mobile phones is often bent, which is prone to damage to the cable insulation sheath or damage to the interface, resulting in charging failure or other safety issues.
In the bending test, 9 samples failed to pass the bending test, among which 5 samples failed to charge after the test, and the charging connector of an unbranded sample had completely broken off; 4 samples failed the bending test. After that, it has not passed the withstand voltage test verification.

13 sample ports deformed under pressure
The port of the charging data cable is prone to breakage when subjected to stress such as accidental pressing.
After testing, 33 samples have no deformation after applying force and can be used normally.
The remaining 13 models were all deformed, and the interface of 11 samples was excessively bent during the process of thrust application.
Among them, for the sample whose nominal brand is Pinsheng (model TC-FC-1000), the connector completely fell off during the test.
The sample whose nominal brand is Anke (model A8622) failed to charge after the test.

Charging data line industry implementation standards fragmented
The China Consumers Association stated that through this comparative test and related market research, it was found that the current charging data cable industry has typical problems such as incomplete product identification and fragmented implementation of standards.
"Most of the standards expressed in the samples are corporate standards, and a few are industry standards that have expired, or safety standards that have nothing to do with data cable products."
China Consumers Association also emphasized that the comparative test only compares the performance of the test samples, and does not judge whether they are qualified or not.
The comparison test results are only responsible for the samples, and do not represent the performance of different models and batches of the same brand.
As for the No. 5 and No. 23 samples that the enterprise/brand owner does not recognize as the brand’s product, China Consumers Association stated that it has notified the platform to trace the source of the product, and hopes that the platform will confirm the authenticity of the product as soon as possible and punish merchants who do sell counterfeit products. to clean up.
