At Shenzhen Merryking Electronics, we have always believed that progress is not a destination, but a continuous journey. This month, we marked two monumental milestones on that journey: our 20th anniversary and the grand opening of our brand-new, sprawling 5,000 sqm factory in Dongguan. It was a day of immense pride, reflection, and excitement for the future, shared with our dedicated team and valued partners.

Two Decades of Trusted Power Solutions
For 20 years, Merryking has stood as a reliable partner to manufacturers, wholesalers, dealers, and distributors worldwide. Our foundation was built on a simple yet powerful promise: to deliver high-quality, efficient, and safe power adapters that our B2B clients can integrate with absolute confidence. From our core range of 1-420Watt Power Adapters to the ubiquitous 5V USB Chargers and advanced 18-140W PD Fast Chargers, we have powered millions of devices, enabling our clients to bring their products to market seamlessly.
Expanding Capacity, Elevating Standards: Our New Dongguan Hub
To meet the growing global demand and to future-proof our operations, we are thrilled to announce the inauguration of our new manufacturing facility. Located at Unit 1501, Building 49, Phase 3, JD智谷(JD Zod Valley), Yantian Village, Fenggang Town, Dongguan, this advanced factory is a testament to our commitment to growth and innovation.
This 5,000 sqm facility is more than just a larger space; it's a strategic upgrade designed to enhance our capabilities across the board:
Unmatched Production Capacity: The factory is equipped with three new, high-speed production lines, integrated with advanced automation assembly equipment. This powerful setup elevates our monthly production capacity to an impressive 800,000 pcs, ensuring we can handle your largest and most time-sensitive orders with unparalleled efficiency.
Massive Storage Solutions: Understanding the importance of a robust supply chain, we have dedicated a 2,000 sqm area within the facility to warehousing. This massive storage space is designed to significantly ease our clients' inventory pressure, allowing for more flexible order management and faster turnaround times.
Enhanced R&D Focus: A dedicated area for research and development will accelerate our innovation, particularly in fast-charging technologies, ensuring we stay at the forefront of the power supply industry.
Dual-Factory Strategy: Powering Your Supply Chain with Greater Flexibility
With the addition of our Dongguan facility, Merryking now operates two strategic manufacturing hubs—the original factory in Shenzhen and the new plant in Dongguan. Together, these two factories bring our total monthly production capacity to 1.5 million units, significantly enhancing our ability to serve clients across diverse product lines and regions. Our dual-factory setup enables synchronized production planning, resource optimization, and risk diversification, providing you with greater supply chain resilience and order fulfillment flexibility.
Our Promise to Our B2B Partners
This expansion is ultimately for you—our clients. In a dynamic market, you need a supplier that is not only reliable but also scalable and resilient. Our new Dongguan factory, together with our established Shenzhen facility, allows us to:
Guarantee Supply and Speed: With a combined monthly output of 1.5 million units, we ensure a consistent and reliable flow of products, from 1W to 420W Power Adapters to the latest PD Fast Chargers.
Reduce Your Logistics Burden: The 2,000 sqm warehouse in Dongguan, complemented by our Shenzhen storage capacity, acts as an extension of your own inventory, providing greater flexibility and reducing your storage costs and complexities.
Offer Competitive & Custom Solutions: Improved operational efficiency and advanced automation across both factories help us maintain our competitive edge and make us better equipped to collaborate on developing tailored power solutions.
The celebration was a vibrant reflection of our journey and our aspirations. As we cut the ribbon and looked around the new facility, we were filled with gratitude for everyone who has been part of our story.
Looking Forward
As we power into the next decade, our mission remains unchanged: to be your most reliable and efficient source for power adapters. Our new, automated factory in Dongguan, together with our original Shenzhen plant, is our concrete pledge to continue that mission with renewed vigor, expanded capacity, and an unwavering focus on your supply chain success.
We invite our existing and potential B2B clients to see this new chapter as an opportunity. Let's discuss how our enhanced dual-factory capabilities can power your next big project.
Here's to the next 20 years of powering progress, together!
