We utilize the latest AI-driven and automated equipment to ensure product reliability.


















We have automatic dispensing machines, SMT machines, reflowing soldering, fully automatic vertical and horizontal AI plug-in machines, wave soldering, computer testers, and high-low temperature environment testing equipment. This robust infrastructure provides an effective guarantee for the high quality and longevity of our outdoor power adapters.
Modern enterprises require more than just a "power brick." The current market for wholesale outdoor power adapters demands high energy density, thermal stability, and multi-protocol compatibility (PD 3.0, QC 4.0). Companies in the RV, maritime, and telecommunications sectors are increasingly looking for OEM/ODM partners in China who can offer localized support and rapid compliance prototyping.
Gallium Nitride (GaN) is revolutionizing the industry. Our latest adapters leverage GaN to reduce size by up to 40% while increasing efficiency to over 95%. For outdoor applications, this means less heat generation and a longer lifespan for the internal components, making them ideal for sealed, waterproof enclosures.
With the surge in "Green Energy," outdoor power adapters are now being designed to interface seamlessly with portable solar arrays. Our 100W foldable solar panels and DC-to-DC converters represent the next frontier in off-grid power, providing reliable charging for everything from smartphones to 5G smart base stations.
Everything you need to know about outdoor power adapter procurement and compliance.
Our products are fully certified for global markets, including UL/cUL (North America), CE/GS/BS (Europe), SAA/RCM (Australia), PSE (Japan), and CCC (China). We also comply with RoHS environmental standards.
Yes. With over 30 years of experience, we specialize in OEM/ODM manufacturing. We can customize voltage, current, casing (waterproof/dustproof), and cable types to meet your specific project needs.
Thanks to our automated assembly lines and 700+ staff, we maintain a monthly output of 1 million units. Standard lead times range from 15 to 30 days depending on customization requirements.
We use ultrasonic welding for seamless sealing and premium weather-resistant materials. Every unit undergoes rigorous Aging Tests and high-low temperature environment testing to ensure performance in extreme conditions.
