⸻ Hello, I reviewed the reference module QC4.0 QC3.0 100W Power Bank Module and I can support a full custom redesign with improved reliability and production readiness. My approach will start by defining the system architecture: multi-cell (e.g., 4S/5S) 18650 battery management, bidirectional buck-boost topology, and proper USB-C PD + QC protocol handling. The design will support up to 100W (20V/5A) output with efficient power conversion and stable operation . I will select a suitable PD controller IC (with PPS/QC support) integrated with a high-efficiency synchronous buck-boost stage. Protection features (OVP, OCP, OTP, short-circuit) will be fully implemented. PCB design will focus on: * High-current paths (5A+) with proper copper thickness and thermal vias * Clean USB-C routing and impedance control * EMI reduction and stable feedback loops * Compact but thermally optimized layout Deliverables include schematic, 4-layer PCB, BOM with alternatives, Gerbers, and assembly files, plus a brief design report covering power calculations and validation strategy. Toolchain: Altium Designer (or KiCad) Timeline: 7–10 days for first revision I have strong experience in power electronics and embedded

@yaroslavmark

Hi, I am an embedded hardware engineer with 8+ years of experience in power electronics and high-speed PCB design, having delivered 25+ multi-layer boards including USB PD (up to 100W) and QC3.0/4.0 solutions with verified efficiency above 94% and stable thermal performance under 5A load. I have previously designed battery-powered systems using 18650 cells with integrated BMS, achieving optimized charge balancing and protection compliance (OVP/OCP/OTP) across production runs exceeding 10,000 units. Approach ✅ I will reverse-engineer the reference module to extract functional blocks (PD controller, buck-boost stage, battery management, and protection circuits) and define schematic architecture using proven ICs like IP5328/FP6601-compatible solutions. ✅ I will design a 4-layer PCB with controlled impedance routing for USB-C PD lines, optimized power paths for 5A current, and proper thermal dissipation using copper pours and via stitching. ✅ I will validate the design through simulation (power integrity, thermal) and generate manufacturing-ready files including BOM, Gerbers, and assembly drawings. Questions ✅ I need to confirm whether you require full compliance with USB PD 3.0 PPS profiles and QC4.0 certification or just functional equivalence. ✅ I need to know your preferred battery configuration (number of 18650 cells, series/parallel) and whether integrated BMS or external protection IC is required. Best, Yaroslav

Best Power Bank PCB Design Expert for Fast-Charge Systems! ⭐⭐⭐⭐⭐ Dear Client, What matters most here is not just making a power bank PCB work, but building one that handles fast charging, current flow, thermal behavior, and manufacturability properly from the first revision. I can help by: ✅ defining the power architecture around QC/PD behavior, 18650 pack handling, charging/discharging paths, and indicator logic ✅ designing the schematic and PCB with proper current paths, protection, thermal handling, and compact routing ✅ delivering the complete manufacturing package with BOM and production files so the board is ready for prototype build This keeps the project focused on a charger board that is usable, compact, and easier to validate. Two quick questions: 1. Are you targeting a direct replica of the reference board, or a functionally equivalent redesign? 2. Is the stronger priority highest output capability or compact size in V1? If you message me, I can outline the cleanest architecture before the PCB is locked. Best regards, Prat PCB Must Innovations

Hi, I'm Akshay, an Electronics Systems engineer and founder of ZiroEDA, incubated at IIT Madras. We specialize in AI-accelerated PCB development with rigorous engineering review to deliver professional-grade boards faster and with higher reliability. I've reviewed the 100W PD Power Bank module you referenced. Designing for 100W (20V/5A) is a high-stakes task; it requires elite thermal management and EMI discipline to ensure the board doesn't overheat or ripple during peak 5A charging cycles. What I bring to this specific project: • High-power DC-DC expertise (100W USB-PD, buck-boost) • Robust thermal design (2oz copper, vias, layout) • AI-assisted validation for fast, reliable design • Production-ready files (Gerber, BOM, PnP) Approach: Component Selection: Verify the Buck-Boost controller (e.g., IP5389/SC8815) for 100W PD compliance. High-Power Layout: Design a 4-layer stackup to isolate high-current power loops from sensitive LED/Display signals. Firmware/Protocol: Ensure the USB-C CC logic correctly handles the PD 3.0/4.0 handshake. Final Handoff: Complete manufacturing files + 3D Step model for your enclosure. Happy to jump on a quick chat to review your specific requirements and start right away. Best, Akshay Founder, ZiroEDA | IIT Madras

I have designed -powered PCBs before — including a compact wearable with Li-ion power management, charging circuitry, protection logic, and USB power path, fabricated and delivered as a working prototype. Battery management PCB design with multi-rail power, charging ICs, and USB interfaces is work I've done many times. For this powerbank PCB I will design: • QC4.0 + QC3.0 + USB PD fast charge input stage with correct handshake logic • Dual USB output with 5A/100W capable routing, proper trace width and copper pour for current capacity • 18650 cell management: charge, discharge, cell balancing, over-current and over-voltage protection • Micro + Type-C input support with correct CC resistor configuration for PD negotiation • LED charge indicator circuit • Compact, thermally sound layout with high-current paths clearly separated from control logic Delivery in 2 days: KiCad schematic + PCB layout, Gerbers, BOM with MPNs. I work primarily in KiCad — if Altium source files are a strict requirement please confirm. Otherwise the full Gerber + BOM package will be identical. How many 18650 cells is the design targeting — single cell or multi-cell pack?

@Robertx2002

The key challenge is integrating QC4.0 and QC3.0 protocols with dual USB PD fast charging at 5A output, while maintaining a compact footprint and stable power delivery for 18650 battery cells. Without precise protocol handling, the module risks inconsistent charging speeds or device incompatibility. I will design the PCB using a high-frequency DC-DC converter paired with dedicated USB PD controllers for seamless negotiation across QC4.0/QC3.0 standards. Careful layout and thermal management will ensure 100W output with minimal losses and optimal heat dissipation, ensuring reliability under continuous load. This approach guarantees efficient, safe charging with clear power delivery indicators via LEDs for user feedback. When should we start integrating these specifications into your existing supply chain?

Hi, this is exactly the kind of PCB reverse-engineering and redesign work I handle. I’m familiar with QC3.0/QC4.0 and USB-PD power bank architectures, including multi-cell (3S/4S/5S) battery systems, bidirectional charging, and high-current layout design. I can analyze this module, recreate the schematic, and redesign it into a cleaner, more reliable, and production-ready PCB. From what you shared, this type of board typically integrates: -PD/QC protocol controller (USB-C negotiation for up to 100W) -DC-DC conversion stage (buck/boost depending on battery stack) -Battery management for 18650 cells (often 3S–5S configuration) -Dual USB outputs with protocol switching I can help you: -Reverse engineer the full schematic from this board -Identify the main controller ICs and power topology -Redesign a cleaner PCB (better layout, thermal, current handling) -Improve reliability and manufacturability -Optionally customize features (size reduction, better efficiency, different battery config) If you want to go further, I can also help redesign it into a custom product (your own version, not just a copy) with improved performance and cleaner architecture. Please share your target (same function vs improved version), and I’ll propose a clear approach and timeline. Thank you. Jude.
