Anker Innovations’ Portable Energy Storage Power Supply Receives TÜV SÜD’s First A+ Level Endurance Certification for Portable Energy Storage Power Supplies

SHENZHEN, ChinaJune 12, 2026 /PRNewswire/ — Recently, TÜV SÜD (hereinafter referred to as “TÜV SÜD”) awarded Anker Innovations Co., Ltd. (hereinafter referred to as “Anker Innovations”) the first A+ level endurance certification for portable energy storage power stations, for its Anker SOLIX S2000 portable energy storage power station (model AS220, hereinafter referred to as the “S2000 portable energy storage power station”). This certification signifies that the product achieves long-duration performance in home backup power scenarios while maintaining a compact and portable design, delivering an enhanced user experience. Mr. Li Yiyong, R&D Director of Anker Innovations’ Energy Storage Business, and Mr. Zhu Xiaobin, Senior Manager of the Electrical and Electronic Department for Southern China, Consumer Products Service, TÜV SÜD Greater China, along with other representatives from both parties, attended the certification ceremony.

Currently, portable energy storage power stations have become deeply integrated into daily life, with expanding use cases ranging from mobile power for outdoor camping and road trips to the essential need for home emergency backup power. This has led to “advanced demands” from consumers regarding product performance: they are no longer satisfied with simply “having power available,” but instead seek a higher-level experience characterized by “longer backup power endurance, more compact design, and lower energy consumption“. Based on a keen insight into market trends, TÜV SÜD has developed a more specialized and comprehensive endurance evaluation and certification scheme, building upon the foundation of meeting basic safety requirements.

During this certification process, TÜV SÜD’s technical team conducted comprehensive professional testing and evaluation of Anker Innovations’ S2000 portable energy storage power station according to established standards. The testing focused on core indicators such as output conversion efficiency, energy retention capability, and energy-to-volume ratio. Ultimately, the product demonstrated excellent performance across all dimensions of testing, successfully earning TÜV SÜD’s first A+ level endurance certification for portable energy storage power stations. This certification not only highlights Anker Innovations’ ongoing commitment and practice in the R&D and performance optimization of portable energy storage products but also signifies that the S2000 portable energy storage power station can deliver longer-lasting power support while occupying less space, thereby precisely meeting high-quality electricity demands for home emergency and multi-scenario use.

In the emerging track of portable energy storage, TÜV SÜD stands at the forefront of the industry. While reinforcing traditional testing foundations such as electrical safety, energy efficiency, and environmental chemistry, it leverages a keen sense of global consumer trends to continuously build a high-value-added specialty certification system. From quantitative ratings for compactness to rigorous evaluations for niche scenarios like shock resistance, low noise, and long endurance, each new standard launch directly addresses industry pain points and fills market gaps. Looking ahead, TÜV SÜD will continue to deeply integrate its 160-plus years of expert knowledge with localized service networks, collaborating with industry partners like Anker Innovations to transform laboratory data into quality commitments perceptible to consumers, driving the industry from “rapid expansion” towards a high-quality development phase where “standards lead the way.”
