There are so many mobile batteries out there right now. Some of them are inferior products, and their safety has been talked about, such as an explosion accident. So how do you know which mobile battery is safe? The "PSE mark" is one of the guidelines.The
PSE mark is a mark that is obligatory to be displayed on electrical products that comply with the standards stipulated by the national "Electrical Appliance and Material Safety Law". The PSE mark is obligatory for electrical products that are mainly used by connecting to an outlet. Lithium-ion batteries, which are parts of mobile batteries, are also covered.
On the other hand, it has been said that mobile batteries do not fall under the "electrical appliances" stipulated by the Electrical Appliance and Material Safety Law. Lithium-ion batteries were treated as part of a device called a mobile battery, so they were not subject to the PSE mark.
However, in response to the frequent occurrence of accidents, the Electrical Appliance and Material Safety Law was amended in 2018, and the mobile battery itself is also covered. A one-year transitional period has been set after the revision, but after February 1, 2019, when this period ends, mobile batteries without the PSE mark cannot be manufactured, imported, or sold at all. increase.In order to display the
PSE mark, it is necessary to clear a number of technical standards and prove that it has undergone hundreds of aptitude tests.
This is true not only for domestically manufactured products but also for imported products.
Even if it meets the technical standards in your own country, it cannot be sold in Japan without the PSE mark.
In addition, since it is essential to include the corporate name of the operating company that sells in Japan on the PSE mark, there is also the aim of excluding unscrupulous vendors who handle and sell inferior goods.
