Explore our premium high-efficiency chargers, smart distribution power strips, and custom interface hubs.
Shenzhen RF-Core Charger Co., Ltd. is a leading high-tech enterprise integrating comprehensive research and development (R&D), advanced manufacturing, and global sales. We specialize in engineering next-generation charging and connectivity solutions for modern digital infrastructure.
The cornerstone of our technology portfolio is our multi-port charging architecture. We design and manufacture 10-to-100 port high-density chargers, intelligent storage charging cabinets, multi-function USB hubs, and high-power fast charging units. Guided by our values of efficiency, reliability, and innovation, we build safety-first devices compatible with global standards.
Our solutions are optimized for high-density environments like schools, hospitals, offices, and logic hubs, balancing current dynamically to preserve battery health and prevent overcharging.
For global enterprise buyers, safety compliance is not just a regulatory checkbox; it is the ultimate shield against operational liability, property damage, and safety incidents. A CE mark indicates that the product complies with the safety, health, and environmental requirements of the European Economic Area (EEA).
Ensures that our chargers operate safely within standard voltage thresholds. Under LVD, our chargers undergo dielectric strength testing, insulation resistance validation, thermal creepage assessment, and electrical clearance distance monitoring to prevent shock hazards.
High-frequency switching regulators generate electromagnetic interference (EMI). EMC alignment ensures that RF-Core chargers do not disrupt surrounding office, educational, or medical equipment, while retaining high immunity to incoming electrical surges.
Restricts hazardous materials (Lead, Mercury, Cadmium, Hexavalent Chromium, PBB, PBDE) in component manufacturing. Essential for eco-conscious enterprises, reducing environmental impact during recycling and disposal.
| Protective System | Technical Mechanism | Enterprise Operational Benefit |
|---|---|---|
| Over-Current Protection (OCP) | Monitors current limits via specialized shunt resistors, shutting down active lines if current exceeds safe levels. | Prevents downstream components and client device batteries from expanding or catching fire. |
| Over-Voltage Protection (OVP) | Optocoupler-based secondary feedback loop clamps output voltages instantly if controller loops fail. | Saves sensitive motherboards (e.g., GPS watches, iPads, laptops) from fatal over-voltage spikes. |
| Short-Circuit Protection (SCP) | Hiccup-mode controller isolation triggers instantly under zero-resistance loads, recovering once short is cleared. | Prevents structural fires caused by damaged user cords or contaminated ports. |
| Over-Temperature Protection (OTP) | Negative Temperature Coefficient (NTC) thermistors track internal components, throttling power outputs as needed. | Ensures safe operation inside enclosed, unventilated charging lockers and high-density environments. |
The industrial power sector is undergoing a major technological shift. Silicon-based transistors are reaching physical limits, paving the way for Gallium Nitride (GaN) semiconductors. GaN offers bandgap properties that allow electrical fields to pass through faster, leading to high-efficiency power conversions.
At RF-Core, we combine GaN components with dynamic power allocation. When multiple laptops are plugged into our 12-port or 60-door systems, the charger monitors power draw, distributing higher wattage to drained batteries and scaling back on fully charged units.
Shenzhen, Guangdong is the global epicenter for electronics hardware development. Partnering with a specialized manufacturer like Shenzhen RF-Core Charger Co., Ltd. offers clear supply chain benefits for overseas distributors and procurement officers.
With raw PCB assemblers, enclosure mold makers, and software developers co-located in the Pearl River Delta, RF-Core shortens product design phases. Custom designs move from CAD blueprints to working samples in weeks.
Quality control is integrated throughout our manufacturing process. We conduct automated optical inspections (AOI), high-pot isolation tests, and dynamic burn-in tests under full electrical loads at high temperatures.
Our production lines operate under ISO 9001:2015 standards. We manage full compliance audits for international certifications, including CE, FCC, CCC, RoHS, and CB, ensuring smooth importing and customs clearance.
Different industries present unique operational demands. Modern charging solutions must adapt to specific environments to ensure safe, efficient, and reliable performance.
Digital learning requires charging and storing dozens of tablets and laptops daily. Our 60 Door Smart Storage Locker Cabinet allows teachers to store, lock, and charge classroom devices securely. Built-in thermal management prevents heat buildup in enclosed compartments.
Modern offices require clean desks and versatile connectivity. Multiport hubs, such as our 8-in-1 USB Type C Hub Multiport Adapter and 2500W Smart EU Socket Power Strips, keep desks organized while charging smartphones, power banks, and laptops from a single outlet.
Hotels, airports, and transport terminals serve global travelers with varying plug standards. Deploying the Startnow All in One Universal Travel Adapter alongside multi-port charging stations ensures guests can charge devices safely regardless of country-specific connections.
Industrial environments require robust hardware. Logistics facilities charging hand-held scanners and GPS trackers use our Custom 4-Port Industrial Hub with ESD and 350W Surge Protection to prevent electrostatic discharge and voltage spikes in dusty, high-vibration settings.
Our engineering processes ensure every high-efficiency charger complies with global quality standards. Here is how we manage development, testing, and delivery from factory floor to deployment.
We review custom voltage, port configurations, and shell requirements with client engineering teams.
We build structural PCB layouts, select certified components, and construct prototype enclosures.
Prototype units undergo thermal profiling, ripple tests, and safety margin evaluations.
We work with third-party testing labs to secure official CE (LVD/EMC) and FCC test reports.

High efficiency is defined by conversion rates. Standard chargers convert roughly 75% to 82% of AC wall power, losing the rest as heat. RF-Core chargers utilize active rectification and GaN transistors to achieve conversion efficiencies of 89% to 94%. This helps meet DoE Level VI (US) and CoC V5 Tier 2 (EU) energy rules, lowering standby power consumption to under 0.075W.
CE certification indicates that a charger meets European directives for safety, health, and environmental protection. For power adapters, it requires compliance with the Low Voltage Directive (LVD 2014/35/EU), evaluating safety from high voltages, and the Electromagnetic Compatibility Directive (EMC 2014/30/EU), verifying that the charger won't interfere with other wireless and electronic devices.
Our multi-port chargers use a smart central control chip (IC) to communicate with connected devices. It detects each device's charge level and power requirements. For example, if you connect a 65W laptop and a 15W phone to a 100W multi-port charger, the controller dynamically routes 65W to the laptop and 15W to the phone. If a third device is plugged in, the IC recalculates the power distribution to prevent overloads while maintaining optimal charging speeds.
Turnaround times depend on the complexity of the design. Standard modifications (like custom branding, logo printing, or simple port adjustments) take 2 to 3 weeks. Full custom projects (including design of new PCBs, custom molds, and regulatory certifications) take 6 to 12 weeks. We provide prototypes and test reports for evaluation prior to starting mass production.
Safety in high-density systems is managed on three levels: physical, thermal, and electrical. Physically, we use flame-retardant steel structures with secure ventilation pathways. Thermally, temperature-activated cooling fans exhaust heat during peak charging cycles. Electrically, each charging tier is equipped with dedicated over-current and surge protection circuits to isolate any faulty lines without affecting the remaining ports.
Reliable components designed for continuous commercial use and demanding operating environments.
