The Celebrat CB-40 USB Data Cable USB-A to Micro USB Fast Charging 3A (Silicone) is a heavy-duty, ultra-flexible charging and data synchronization cable engineered for high-current power delivery and everyday device interconnectivity. Encased in a skin-friendly, food-grade liquid silicone elastomer jacket, it provides high tangle resistance, thermal stability, and mechanical fatigue endurance compared to standard PVC or TPE cables. Designed to support fast charging up to 3.0A at 5V–9V and high-speed USB 2.0 data synchronization at 480 Mbps, it provides reliable power delivery and stable communication for microcontrollers (Arduino, ESP32, ESP8266), single-board computers, power banks, and legacy Android devices.

Features

• Ultra-Soft Liquid Silicone Jacket: Highly flexible and resilient to permanent kinks; coils smoothly without knotting and retains its soft-touch feel even after prolonged handling.
• 3.0A High-Current Fast Charging: Low-resistance heavy-gauge copper power lines minimize internal IR voltage drops, allowing maximum fast-charge current delivery to battery-operated electronics.
• Simultaneous Fast Charge & Data Sync: Fully populated 4-conductor wiring enables simultaneous high-speed data transfer and battery charging without interference or voltage sag.
• Reinforced Anti-Split Strain Relief: Extended flexible neck collar around both the USB-A and Micro-USB terminations distributes mechanical bending stress, preventing split jackets at high-wear junction points.
• Stain & Dirt Resistant: Smooth, hydrophobic silicone coating repels dust, lint, and grease, and wipes clean easily with a damp cloth or alcohol wipe.

Common Applications

• Microcontroller Programming & Power: Supplying stable 5V DC power and serial data communication to Arduino Uno/Nano (Micro-B versions), NodeMCU ESP8266, ESP32 DevKit, and Raspberry Pi Pico boards.
• Single-Board Computer Power: Powering low-current SBCs such as the Raspberry Pi Zero, Zero 2 W, and Raspberry Pi 3B+ without triggering low-voltage brownout warnings.
• Mobile Electronics & Peripherals: Fast-charging legacy smartphones, tablets, Bluetooth speakers, wireless headphones, and rechargeable LED work lights.
• Power Bank Recharging: Connecting fast-charge wall bricks to high-capacity portable power banks via their Micro-USB input ports.
• DIY Electronics Test Benches: Supplying reliable DC bus current to solderless breadboards, sensor breakout boards, and benchtop prototype rigs.

Usage Tips

• High-Current Charging Requirements:
  • To achieve the full 3.0A fast charging speed, connect the cable to a USB-A power adapter or wall charger rated for at least 5V 3A or 9V 2A (QC 3.0 compatible).
  • Standard PC USB 2.0 ports are hardware-limited to 500 mA (0.5A) and will charge high-capacity batteries at a much slower rate regardless of cable capacity.
• Micro-USB Port Insertion Care:
  • Unlike reversible USB-C, Micro-USB connectors are asymmetrical and keyed.
  • Verify the trapezoidal orientation of the connector pins before plugging it into your device or development board. Forcing the connector upside down will snap the internal plastic tongue or shear the surface-mount solder pads off the circuit board.
• Serial Communication Troubleshooting:
  • If your computer does not recognize an attached ESP32 or Arduino board, ensure the micro-USB plug is seated completely into the port. Some bulky cases or PCB housings can prevent the short micro-USB shoulder from clicking all the way in.
  • Because this cable carries full data lines (D+ and D-), it supports firmware flashing and serial monitoring; if COM ports fail to show, inspect device driver installation (e.g., CP2102 or CH340).
• Cleaning & Maintenance: If the silicone jacket picks up workshop dust or adhesive residue, wipe the cable down using a lint-free cloth moistened with 70% to 90% Isopropyl Alcohol (IPA). Avoid cutting the soft outer silicone on sharp PCB header pins or chassis metal edges.
