In an era where mobile devices have become indispensable companions for daily life and travel, the demand for shared power banks has surged exponentially, driving the rapid development of the industry’s manufacturing sector. At the forefront of this booming market stands WELINK, a brand synonymous with high-quality, intelligent, and reliable shared power solutions. Behind every WELINK sharing power bank lies a state-of-the-art manufacturing factory, where precision engineering, automated production, and strict quality control converge to deliver products that redefine convenience and safety for users worldwide.

Located in Shenzhen, the global hub of electronic manufacturing, WELINK’s shared power bank factory is a testament to the brand’s commitment to innovation and efficiency. Covering a vast area, the factory integrates R&D, production, testing, and packaging into a seamless workflow, boasting an annual output capacity of over 6 million shared power banks and 800,000 charging cabinets, with products exported to more than 30 countries and regions across the globe. As a professional OEM/ODM manufacturer, WELINK has established long-term strategic partnerships with leading brands in the shared power bank industry, leveraging its robust production capabilities to meet diverse market demands.

The manufacturing process of WELINK sharing power banks is a model of precision and automation, addressing the industry’s pain points of low efficiency and inconsistent quality in traditional manual or semi-automated production. The factory is equipped with advanced automated assembly lines, featuring a series of specialized equipment that ensures each product meets the highest standards. The production journey begins with the preparation of core components, including high-quality lithium polymer batteries, PCBA (Printed Circuit Board Assembly), plastic casings, and insulation materials such as red cotton tape—all carefully selected to guarantee performance and safety.

The assembly line follows a streamlined, modular design, with each station dedicated to a specific task, creating a seamless production flow. First, the bottom case labeling station uses cylinder-driven automated devices to precisely attach red cotton tape to the power bank’s bottom case, ensuring accurate positioning and protection for internal components. Next, the battery shaping and cutting station processes lithium battery tabs, using precision flattening and cutting mechanisms to ensure consistent size and shape, laying the foundation for stable subsequent welding. The connection piece shaping and laser welding station then trims and flattens the connection pieces, followed by laser welding to bond them firmly with the battery, a process that ensures strong conductivity and structural stability through advanced laser technology and elastic pressing structures.

After the core assembly, semi-finished products undergo rigorous testing at the semi-finished product testing station, where automated equipment conducts power-on inspections to detect potential faults in the battery and circuit board connections. The upper case assembly station then attaches graphene sheets to the upper case—enhancing heat dissipation—and the case pressing and buckling station securely fastens the upper and lower cases, completing the shell assembly. Finally, the finished product performance testing station conducts comprehensive inspections, including charging and discharging tests, short-circuit protection tests, and low-voltage protection tests, ensuring every WELINK sharing power bank meets international safety standards such as UN38.3.

What sets WELINK’s manufacturing factory apart is its unwavering focus on technology innovation and quality control. Backed by a strong R&D team and an open IoT SDK framework, WELINK integrates intelligent technology into every product, enabling features such as 65W fast charging—capable of charging a smartphone from 20% to 80% in just 30 minutes—and one-click QR code rental for effortless user access. The factory’s quality management system covers every link of production, from raw material inspection to finished product delivery, with professional QA teams conducting strict inspections to ensure zero defective products leave the factory. Additionally, WELINK’s products hold various international certifications, adapting to different socket standards across regions such as the US, EU, UK, and Japan, making them suitable for global markets.

Beyond production excellence, WELINK adheres to a philosophy of sustainable development and partnership-driven growth. The brand’s mission is to create positive impact through innovation, viewing challenges as opportunities to drive industry progress. The factory adopts environmentally friendly production processes, optimizing energy consumption and reducing waste, aligning with WELINK’s vision of a world where sustainability is no longer a differentiator. Moreover, WELINK offers comprehensive customization services, including logo printing, design customization, and software development, catering to the unique needs of partners and empowering them to succeed in the competitive shared power bank market.

As the shared power bank market continues to evolve, WELINK’s manufacturing factory remains at the forefront of innovation, constantly upgrading production technology and optimizing product performance. From automated assembly lines to strict quality control, from intelligent features to global adaptability, every aspect of the factory’s operations reflects WELINK’s commitment to delivering high-quality, user-centric shared power solutions.
