According to the latest data, during the first three quarters of this year, Shenzhen exported lithium batteries to more than 200 countries and regions, with the export volume surpassing 80 billion yuan, marking a year-on-year increase of over 30%. Among these exports, portable energy storage devices held a substantial market share. The overseas popularity of these devices can be attributed to two primary factors: Firstly, there is a robust demand in international markets. For instance, camping and RV travel are deeply ingrained cultural activities in Europe and the United States, necessitating the use of mobile and portable energy solutions. In regions where power grids are unreliable, households frequently rely on such devices as emergency power backups. Secondly, Shenzhen boasts a comprehensive lithium battery industry chain, encompassing everything from battery cells and battery management systems to complete device integration. All these components can be researched, developed, and manufactured locally. The products are not only lightweight and portable but also rechargeable via solar panels, aligning with eco-friendly practices. Furthermore, these products have secured international safety certifications and are designed to be compatible with voltage standards across different countries, thereby winning the trust and preference of overseas users.
