Shenzhen’s Innovations Drive Global Demand for Portable Energy Storage Solutions

Approximately 4,400 kilometers away from Shenzhen, the Kekexili Nature Reserve faces harsh weather and scarce resources. For the patrol teams working in this challenging environment, which includes snow-capped mountains, ice fields, and permafrost, a steady and reliable power supply is essential. A batch of portable solar energy storage products, having traveled from Shenzhen, has proven invaluable here. Equipped with low-temperature protective cases, these products operate stably even in extreme cold, providing continuous power to communication devices and significantly enhancing the safety and efficiency of ecological protection efforts. They have become a crucial support in conservation work.

There is a saying in the industry that “portable energy storage looks to Shenzhen.” Thanks to a robust innovation ecosystem and industrial cluster, several local companies in Shenzhen have made significant strides, from technological breakthroughs to scene expansion, and from product creation to global outreach. As a result, “Shenzhen-made” portable energy storage devices are enjoying popularity both domestically and internationally, embodying the concept of “Chinese goods going global.”

Accelerating Market Penetration

In the global portable energy storage sector, China contributes over 90% of the production capacity, with most of it concentrated in Shenzhen. Among the top five companies in the industry worldwide, four are based in Shenzhen. At the Consumer Electronics Show (CES) 2026, Shenzhen Huabao New Energy showcased its latest innovations, including a new generation of outdoor solar canopies and solar-storage Mars robots, capturing global attention. Comprehensive energy solutions became a focal point of the industry.

A representative from Huabao New Energy reported significant year-on-year revenue growth in various overseas markets, with Europe experiencing a 132.30% increase, North America rising by 40.52%, and Asian markets outside China growing by 16.17%. The company’s total global sales have surpassed 6 million units.

Another leading company, Shenzhen Zhenghao Innovation, is expanding its business from portable energy storage to fixed energy storage systems. Their DELTA and RIVER core product lines have allowed them to command nearly 35% of the global portable energy storage market share in recent years. A spokesperson from Zhenghao Innovation noted that over 95% of their revenue comes from international markets, particularly in high-consumption regions such as the United States, Japan, and Germany.

Major consumer electronics giants are also entering the market. DJI recently launched outdoor power supply products focusing on miniaturization and the integration of power sources into everyday life. This marks an important step in bringing portable energy storage into the mainstream consumer market, indicating a new wave of development for Shenzhen’s portable energy storage industry.

Strengthening Competitive Power through Technology

The popularity of Shenzhen’s portable energy storage products both domestically and internationally is fundamentally rooted in technological advancements. On a Japanese e-commerce platform, a portable energy storage device from Huabao New Energy achieved the top sales ranking in its category, thanks to its lightweight design and high energy density. “After 4,000 charging cycles, the battery capacity of this product still maintains at 70%, which is highly attractive for the local market that has a strong demand for emergency preparedness,” said the marketing head of the company’s Japan division.

The impressive product performance is backed by substantial investment in research and development. Data shows that in the first half of 2025, Huabao New Energy’s R&D expenditure reached 76.16 million yuan, with a total of 1,939 patents filed globally, including 661 related to photovoltaics, reflecting a 49.89% year-on-year increase. Zhenghao Innovation has also invested millions in R&D, with over 40% of its nearly 1,000 employees dedicated to research.

Shenzhen’s comprehensive new energy industry chain provides fertile ground for the technical development of portable energy storage companies. The complete industrial cluster, from core materials to final assembly, not only enhances product safety and endurance compared to international competitors but also significantly reduces innovation costs. “With Shenzhen’s complete supply chain, we can manage material procurement within a short cycle of approximately 10 days, lowering costs by around 30%,” said Lei Jianhua, Executive Deputy General Manager of Shenzhen Delan Minghai New Energy.

Transforming “Niche” into a “Necessity”

From outdoor camping to family emergencies, mobile offices to electric vehicle charging, Shenzhen’s portable energy storage companies are continuously expanding product applications based on market demand, transforming portable energy storage devices from “niche outdoor equipment” into essential energy solutions for global consumers.

Amid the backdrop of “Chinese goods going global,” Shenzhen companies are rapidly positioning themselves in the market with a global perspective, establishing a worldwide sales and service network. For instance, Zhenghao Innovation employs a dual strategy of “independent websites + offline supermarkets,” creating country-specific Shopify sites to capture traffic from e-commerce platforms like Amazon, while also successfully entering well-known retail channels like Costco and Walmart to connect directly with consumers worldwide.

Focused on innovation and with products gaining popularity globally, these enterprises benefit from supportive policies. In recent years, Shenzhen has introduced numerous initiatives to support the new energy industry, offering R&D subsidies, innovation funds, and establishing advanced energy storage industrial parks, as well as hosting international digital energy exhibitions to create a global cooperation platform for businesses. The latest data indicates that Shenzhen has attracted over 7,000 energy storage companies.

The international journey of Shenzhen’s portable energy storage companies exemplifies the “Chinese goods going global” initiative. Leveraging Shenzhen’s innovation-driven genes and industrial advantages, these companies are accelerating product upgrades and expanding their applications, ensuring that “Shenzhen-made” continues to lead global trends in portable energy storage consumption, providing valuable insights for China’s new energy industry to expand internationally.
