Featured 38W & Heavy-Duty Power Assemblies
Industrial, commercial, and consumer grade extension boards integrated with intelligent over-current protection and optimized semiconductor thermal paths.
Strategic Procurement Dynamics in the 38W Fast Charging Era
How the convergence of Power Delivery (PD 3.0) and Quick Charge (QC 4+) at the 38W threshold addresses the sweet spot for modern enterprise hardware ecosystems.
Enterprise Hardware Rationalization
Commercial workspace environments and hospitalities are moving away from proprietary brick transformers. The 38W architecture enables simultaneous high-speed 20W PD charging for flagship smartphones (iPhone/Galaxy) alongside 18W power routing for secondary tablets or peripherals, directly reducing clutter and installation footprint.
- Eliminates dedicated desktop power cubes
- Balances phase loads across massive floor installations
- Lowers total capital deployment costs for commercial fit-outs
Global Safety Margins & Compliance
Scaling power delivery within AC power strips elevates thermal and magnetic interference risks. Our designs incorporate dedicated EMI shielding, Class V-0 flame-retardant enclosures, and isolated flyback transformers that ensure safety clearances conforming strictly to IEC/EN 62368-1 audio/video, information, and communication technology standards.
- UL94 V-0 flame-retardant high-temperature engineering plastics
- Dielectric breakdown isolation rating > 3,000V AC
- Multi-stage surge suppression (up to 1,750 Joules rating)
Supply Chain Decoupling & OEM Scalability
For brand owners and industrial wholesalers, sourcing from an integrated manufacturer guarantees consistent component selection. Jiangmen Heikki manages copper stamping, injection molding, SMT surface mount assembly, and automated burn-in testing under one continuous quality umbrella, insulating importers from secondary supply disruptions.
- Direct procurement of certified high-spec magnetics & controllers
- Full traceability from raw brass bars to finished blister packaging
- High-volume monthly capacity supporting 5M+ operational units
38W Power Topology & GaN Integration Roadmap
Detailed architectural analysis of circuit layout, dynamic protocol handshakes, and next-generation power electronics engineering.
Dynamic Power Partitioning (DPP)
Conventional multi-port strips downgrade total output drastically when secondary loads attach. Our proprietary MCU-managed firmware monitors VBUS lines in microsecond intervals, intelligently assigning 20W (9V/2.22A) to the Type-C PD channel while delivering an independent 18W (9V/2A or 12V/1.5A) to the USB-A port without reset drops or current looping.
Thermal Dissipation Engineering
Housing 38W DC conversion within the confines of standard AC power boards introduces heat build-up. We utilize an over-molded copper busbar structure rather than point-to-point wires, paired with thermal potting gel and aluminum fin diffusers, keeping internal junction temperatures well below semiconductor degradation limits (Tj < 105°C).
Next-Gen GaN Fast-Charging Wave
Looking to future product iterations, Heikki's R&D lab is deploying Gallium Nitride (GaN) switching transistors into high-density 38W and 65W board profiles. GaN eliminates switching losses, operates at 3x higher switching frequencies (up to 300 kHz), and reduces magnetics volume by 40%, yielding ultra-slim, travel-friendly desktop configurations.

Frequently Asked Technical & Sourcing Questions
In-depth responses from our senior electrical engineering and international export logistics team.
How does a 38W fast charging power strip differ from standard multi-port USB boards?
A true OEM 38W configuration employs independent switching channels: a dedicated Type-C PD controller providing 20W (5V/3A, 9V/2.22A, 12V/1.67A) and a separate Quick Charge USB-A port outputting up to 18W (5V/3A, 9V/2A, 12V/1.5A). Conventional boards link USB outputs across a single 5V step-down transformer (often sharing 12W-15W total), which results in trickle charging when multiple devices are inserted. Our 38W module delivers full concurrent rated speed to both connected devices without step-down throttling.
What specific manufacturing controls are implemented to prevent USB overheating inside AC power strips?
Integrating AC mains (110V-250V) and a DC conversion module into a confined plastic casing requires three specific engineering barriers: First, an isolated transformer design that guarantees >6mm physical creepage distance to prevent AC arcing. Second, high-efficiency synchronous rectification replacing traditional Schottky diodes, lifting power efficiency above 91% to minimize heat waste. Third, continuous NTC thermal feedback that throttles current dynamically if internal ambient temps exceed 85°C, ensuring housing surface temperatures remain compliant with touch-safety thresholds (<45°C).
Can Heikki customize housing tools, plug configurations, and cord specs for private brands?
Yes. Jiangmen Heikki Technology is a complete vertical manufacturer with in-house tooling, plastic injection, and SMT lines. We support tailored cord lengths (from 1m to 10m+), pure oxygen-free copper core wire cross-sections (0.75mm², 1.0mm², 1.5mm², or 14AWG), bespoke casing colors, custom master or individual mechanical switch placements, laser-etched branding, and multi-lingual master carton packaging with comprehensive OEM/ODM engineering support.
How do you verify compliance and obtain destination-country certificates for OEM orders?
Our on-site testing facility is equipped for high-voltage insulation tests, glow-wire flame tests (up to 850°C), insertion durability cycles (>10,000 mate/demate cycles), cable pull relief, salt-spray corrosion checks, and temperature rise analysis. For market-specific import programs, we work in lockstep with accredited testing laboratories (such as TUV, SGS, and Intertek) to supply CB reports, CE, UKCA, SASO, GCC, TISI, and KC certificates mapped to the importer’s exact private label name.
What are the standard Minimum Order Quantities (MOQ) and production lead times?
Standard OEM production runs typically begin at 1,000 to 2,000 units per model for custom-branded enclosures and localized plugs. Lead times for initial custom tooling runs span 30-40 days for mold validation and pilot runs; repeat container orders are fulfilled within 25-30 days, backed by our Jiangmen production infrastructure which ships over 5 million pieces annually.
