Recently, the Administration for Industry and Commerce announced the latest inspection results. A total of 40 batches of mobile phone battery adapters produced by 26 manufacturers sold by 19 sales companies in 6 cities including Shantou, Shaoguan, Huizhou, Yangjiang, Zhanjiang, Maoming, etc., were all unqualified after inspection. , The pass rate is 0%! If some of these indicators are unqualified, it may cause the battery to explode and catch fire.
>The universal adapters checked are all unqualified, mainly because the electrical clearances and creepage distances between the primary and secondary transformers in the adapters do not meet the standard requirements. This is likely to allow the user to reach the output terminal with dangerous voltage and cause personal injury. Or cause harm to the device being charged. In addition, there are many adapters because the fire protection design of the shell is unqualified, because the manufacturer did not add flame-retardant materials to them during processing.
In this visit, a noteworthy detail is that although the outer packaging of the universal adapter products sold by these mobile phone stores is very simple, in order to convince consumers of their quality, most of them are marked with manufacturers and simple operating steps. Some even marked relevant parameters such as 3C logo and implementation standards. These implementation standards are varied, some are GB/T1827-2000, some are YD/T999·8-1999 and so on. It is understood that the Ministry of Information Industry has stipulated that the YD/T1591-2006 standard shall be implemented in the inspection of mobile phones into the network from June 14, 2007, that is to say, all new applications for network access licenses produced in China within this time The mobile phones and the matching adapters of China should meet the requirements of this standard, but the reporter did not see this standard on the outer packaging of these products.
In addition, according to industry insiders, the universal adapters of regular manufacturers will provide important product parameters, such as voltage and current information, on the logo, and these really important information are precisely what these products do not have. The reporter learned that most of these products do not have a warranty period, and some only have a one-month warranty period promised by the seller, and the after-sales certificate they provide is not an invoice, but a small piece of paper attached to the fuselage. The Municipal Consumer Council has long pointed out that this is not a valid voucher. In the event of a dispute, only the invoice can effectively protect rights.
