Charging Cable
A charging cable is a wired interconnect that transfers electrical power — and in most cases data — between a power source and a target device, available across multiple connector standards and fast-charge protocol configurations.
Key Attributes:
- Connector standards: USB-C, Micro-USB, USB-A, Lightning (Lightning cables require Apple’s MFi certification, which ensures the use of authorized authentication chips for safe, stable, and fully compatible charging and data transmission.)
- Fast-charge support: USB PD up to 100W (For 100W fast charging, both the cable (5A rated with E-marker) and charger/device must support USB PD 3.0.), QC 3.0/4.0, standard 5V/2.4A
- Cable lengths: 0.5m, 1m, 1.5m, 2m, 3m
- Jacket materials: TPE, braided nylon, PVC
Primary Industry Applications:
- Consumer electronics: smartphones, tablets, laptops, wireless earbuds
- Industrial IoT and embedded systems: device charging and serial data transfer
Charging Cable Overview
LCSC charging cables deliver reliable power transfer and data connectivity for a broad range of electronic devices, from consumer smartphones to industrial embedded systems. Built with high-conductivity copper conductors, multi-layer EMI shielding, and strain-relief overmolding at the connector housing, they are engineered for both electrical performance and mechanical durability. Support for USB Power Delivery and Qualcomm Quick Charge protocols enables efficient, high-wattage charging without compatibility issues across charger brands. LCSC stocks these cables in a wide selection of connector configurations, lengths, and jacket materials, giving procurement teams a single sourcing destination for multiple product SKUs.
Why Choose LCSC Charging Cables
| Feature | Description | Benefit |
|---|---|---|
| USB Power Delivery (PD 3.0) | Supports up to 100W (20V/5A) via USB Power Delivery — requires USB-C to USB-C, 5A-rated cable with E-marker chip, and compatible charger/device for power negotiation | Enables high-power charging for laptops and tablets; one cable for multi-device use |
| Qualcomm Quick Charge (QC) | Compatible with Qualcomm QC 3.0 / 4.0 (typically up to ~18W–45W depending on device); uses a different voltage regulation mechanism than PD | Backward compatibility with legacy fast-charging devices; broader device support |
| High-conductivity copper core | 20AWG power / 28AWG data, tinned copper stranding | Low resistance drop; stable power at high current (supports 5A transmission) |
| Multi-layer EMI shielding | Foil + braid shield with >85% coverage | Suppresses interference in RF-dense and IoT environments |
| Strain-relief overmolding | Reinforced housing with flexible TPE boot | Extends mechanical life; resists cable fatigue at bend points |
| RoHS & CE certified | Lead-free, halogen-free construction | Compliant with EU and international import regulations |
