Explore our Tier-1 manufactured components designed for rapid power transmission, automotive integration, and gaming hardware support.
In the modern high-performance connectivity ecosystem, the transition from standard charging solutions to USB Power Delivery (USB-PD 3.1) Extended Power Range (EPR) architectures has revolutionized design paradigms. Modern applications—ranging from medical device power modules and automotive auxiliary links to ultra-high-draw gaming laptops and battery arrays—require cables capable of carrying up to 240W (48V at 5A) without introducing impedance mismatches or thermal hazards.
Achieving this level of continuous, high-current delivery demands rigorous mechanical and structural design. Standard consumer cables suffer from substantial line loss and thermal buildup. As premium OEM/ODM partners, we engineering teams rely on oxygen-free high-conductivity (OFHC) copper conductors, low-loss dielectric insulations, and integrated e-Marker ICs (Integrated Circuits) to establish closed-loop handshake configurations. These chips programmatically communicate current capabilities, safety configurations, and structural thermal limits back to the power management controllers of the connected host and sink.
Founded in 2011, Caiku has evolved through comprehensive management and technology scaling upgrades to become a world-class powerhouse in power adapters, smart chargers, and premium connectivity components.
Caiku is your reliable partner. We pledge uncompromising manufacturing standards, strict visual inspections, and comprehensive, personalized OEM/ODM service.
Our ongoing commitment to internal research and development has secured more than 20 distinct patents across Europe, the United States, and China.
Operating under a registered international trademark, our highly reliable adapters and custom cables are shipped to over 100 countries and regions globally.
Our versatile design department handles complex challenges, routinely producing 3 to 10 unique product configurations each month to support clients' shifting needs.
As the digital landscape transitions to higher power density and hybrid optical-copper architectures, the parameters of structural transmission are shifting rapidly. We continuously align our research and development divisions with emerging standards to guarantee future-proof infrastructure for our global B2B clients.
The transition from 100W (20V/5A) to 240W (48V/5A) has unlocked charging configurations for complex consumer computers, high-draw battery stations, and outdoor IoT networks. In order to carry 48V without the risk of electrical arcing when the cable is unplugged, we employ EPR-specific e-Marker ICs. These chips manage physical layer signaling to prevent electrical arcing, safeguarding structural circuitry from sudden voltage surges.
When high-wattage power delivery must co-exist with ultra-high bandwidth data transfers (such as PCIe over USB4 at 40Gbps/80Gbps over lengths exceeding 2 meters), traditional copper wires suffer from signal degradation. Our roadmap includes Active Optical Cable (AOC) hybridization. By incorporating multi-mode optical fibers for high-frequency data signals alongside high-gauge copper conductors for power delivery, we eliminate electromagnetic interference (EMI) while minimizing structural weight.
Environmental governance is a cornerstone of corporate procurement. We are expanding options for post-consumer recycled (PCR) plastics and bio-based thermoplastic elastomers (TPE). These advanced polymers maintain identical tensile strengths and cyclic bending life as traditional PVC, while meeting the strict global restrictions of hazardous substance protocols.
High-current cables do not operate in a vacuum. They are integral to larger power conversion structures. Caiku delivers customized connectivity frameworks across key industries:
High flex life, oil-resistant polyurethane (PUR) jacketing coupled with heavy internal braiding ensures reliable electrical signal transmission in high-noise automated environments.
Designed to handle structural stress, dynamic temperature fluctuations, and exposure to grease, our custom adapters and assemblies satisfy stringent automotive safety margins.
Corrosion-resistant copper alloys and hermetically sealed overmolds prevent moisture penetration, maintaining critical electrical connections in harsh marine environments.
Caiku operates vertically integrated production bases. By maintaining strict control over every stage—from processing copper conductor raw materials to automated chemical foaming—we ensure high yield rates and consistent structural quality.

Operating out of Dongguan—the global epicenter of modern electronics manufacturing—Caiku leverages a robust localized supplier ecosystem. This concentration of raw material processors, connector developers, and plating shops minimizes logistical overhead. Our production lines feature automated assembly techniques that dramatically reduce manual touchpoints, ensuring stable unit economics even during periods of rising labor costs.
This localized advantage translates directly into supply chain stability. While international markets face logistical delays and fluctuating raw material supply, we secure critical metals and polymers locally. This structural resilience enables us to guarantee stable lead times for strategic partners and respond rapidly to sudden spikes in global demand.
Unlike standard custom factories that require months to adapt production tooling, Caiku's tooling department is fully in-house. We transition new customer blueprints into functional physical prototypes in days. By performing mold changes and pilot runs on dedicated test beds, we prevent down-time on our high-volume production lines, accelerating time-to-market for our OEM partners.
Regulatory compliance is a critical priority for enterprise buyers. An uncertified adapter or sub-standard cable can lead to regulatory fines or costly product recalls. Caiku maintains strict compliance programs to ensure our products meet or exceed global standards.
Our products are fully certified for safety and electromagnetic compatibility (EMC), ensuring smooth entry and compliance in European and North American markets.
All polymers, solder alloys, and core components are chemically verified lead-free, cadmium-free, and compliant with environmental standards.
Our designs prioritize electrical and thermal insulation safety, satisfying strict global standards for flame-retardant properties and thermal management.
When sourcing custom power adapters and high-power connectivity components, B2B procurement divisions must look beyond baseline unit pricing to evaluate total lifecycle costs, quality control practices, and regulatory alignment. We support clients through every step of this selection process, working closely with engineering teams to optimize technical specifications:
High-density power transmission equipment optimized for mobile workspaces, smart travel, EV charging station infrastructure, and remote applications.
