Innovative Scenes at the “Afternoon Smart Park” Interactive Exhibition

At the “Afternoon Smart Park” exhibition area, Delanminghai deeply integrated energy storage technology with outdoor living, utilizing lithium iron phosphate battery technology and modular expansion design as technical support to create outdoor energy solutions:

• BLUETTI AORA 100: This portable energy storage power supply is exclusively designed for Japanese households. Its off-white body features a minimalist Japanese style, seamlessly blending into home environments. With a battery capacity of up to 1,152Wh and a continuous output power of 1,800W, it can expand to 2,700W in Hercules mode, fully meeting the diverse needs of camping enthusiasts, DIY players, and emergency responders. The device includes a Japanese interface and a large, clear display for intuitive operation. Due to its outstanding performance and reliability, the AORA 100 was awarded the title of “Best Buy No.1” in the May 2025 issue of Home Appliance Critique.
• BLUETTI Handsfree Series Backpack Storage Products: This series combines a professional outdoor backpack with energy storage capabilities, featuring a lightweight lithium iron phosphate battery. It supports AC power outlets and solar fast charging (fully charged in as little as 3 hours). The backpack includes multiple compartments for storing cameras and emergency kits, and its modular design adapts to professional equipment for photography, hiking, and fishing. It also allows for device charging on the go, perfectly blending practicality with advanced power technology. The Handsfree2 product in this series won the Men’s Health 2025 Technology Product Award.
• BLUETTI AC70P: This compact portable energy storage power supply is now available at major offline retailers in Japan, such as Biccamera and Kojima, making it a top choice for disaster preparedness and camping among young people. It features an 864Wh high-capacity battery with 1,000W output power (peak at 2,000W) and TurboBoost fast charging technology, allowing it to charge to 80% in just 45 minutes. With solar panels, it can be fully charged in just 2 hours. Weighing only 7.2kg, it offers four output methods and seven ports (including USB-C PD 100W), providing efficient power for devices such as drones and laptops, with real-time monitoring through the BLUETTI APP.

In addition to the showcased products, Delanminghai also presented the BLUETTI AC200PL, which features 2,400W output power and a flexible expansion capacity of 2.3-7.8 kWh. This product provides stable power support for large sound systems in the exhibition area and achieves off-grid power supply through solar panels, creating an innovative example of “zero-carbon outdoor activities.”

Technical Excellence: Building an Industry Moat with Thousands of Patents

Since the launch of the world’s first lithium battery portable energy storage PS10B in 2013, Delanminghai has consistently driven industry transformation through technological innovation. As of May 2025, the company has applied for over 1,000 patents, covering three core areas: dimensional drive, fast charging technology, and protection systems.

• HyperVolt™ Dimensional Drive: This technology provides stable output of leading power for 99.5% of devices on the market, fully meeting diverse power needs. It integrates power enhancement modes and phase bonding technology to achieve both over-rated power and stable voltage output, ensuring robust power support for heavy equipment.
• TurboBoost™ Fast Charging Technology: BLUETTI’s TurboBoost fast charging technology offers exceptional charging efficiency, allowing even large energy storage devices to reach 80% battery capacity in just 45 minutes, ranking among the top in the user-side energy storage industry.
• PowerArmor™ Protection System: This system integrates automotive-grade battery core technology with waterproof and anti-corrosion advanced materials management systems, multiple leakage protection mechanisms, and sophisticated battery management system algorithms, ensuring battery safety and reliable power delivery.

Due to its technological leadership, Delanminghai has been recognized as a “National Specialized and New Small Giant Enterprise” and a “Forbes China Emerging Unicorn,” winning multiple CES Innovation Awards.

Global Strategy: From Market Development to Ecological Co-Building

Delanminghai has established a global network covering over 110 countries, driven by “technology going global” and “responsibility going global.” The company has set up wholly-owned subsidiaries in more than 20 countries, including Japan, the United States, and Germany, and maintains a leading market position in user-side energy storage through platforms like Amazon. During the Osaka Expo, the company focuses on outdoor energy applications in East Asia to further strengthen its advantage in the Asia-Pacific market.

In terms of ecological co-building, Delanminghai collaborates deeply with the UN-Habitat to customize solar energy storage products for sub-Saharan regions. Through technology transfer, the company provides clean energy training to 49 African countries, donating over 15,000 sets of equipment, benefiting more than 50,000 people. This initiative not only addresses local household electricity needs but also fosters a localized energy industry chain in Africa through a model of “photovoltaics + energy storage + skills empowerment.”

From crowdfunding successes like the AC500 & B300S, which set an Indiegogo crowdfunding record of $12.19 million in the energy category, to being named among the Top 30 Global Brands by Forbes China, Delanminghai continually defines the boundaries of innovation based on user needs. Through the World Expo as a bridge, Delanminghai is transforming China’s energy storage technology into a global energy transition “soft connection,” writing a new paradigm for green development.
