ddHiFi TC05M3 — 2-in-1 USB-C OTG & Charging Cable

"Enjoy Hi-Fi Music. Never Worry About Battery Again."

The ddHiFi TC05M3 solves the #1 frustration of portable Hi-Fi listening: your charging port is occupied by your DAC/amp, leaving your phone draining fast. With its integrated 2-in-1 design, the TC05M3 simultaneously handles OTG audio decoding and 10W charging — connecting your smartphone, DAC/amp, and power bank all at once. Reinforced with oxygen-free copper cores, double-layer shielding, and lightweight PC+ABS plugs, it’s built for the high-intensity demands of all-day Hi-Fi listening.

⚠ Pre-Purchase Note: The TC05M3 does not support fast charging. It supports standard charging only (maximum 10W). Compatibility may vary across Android phone brands due to differences in USB interface protocols. Please check the compatibility list at the end of this page before purchasing.

2-in-1 OTG + Charging Max. 10W Charging USB-C to USB-C OFC Twisted Core Double-Layer Shielding Lightweight PC+ABS Plugs Aluminum Alloy Ring Approx. 17g

Key Features

  • Eliminate Battery Anxiety — When using a DAC/amp with your phone, the charging port is occupied — leaving you anxious about battery life during long listening sessions. The TC05M3 integrates a charging plug directly into the cable. Simply connect the two cables to your OTG device and power bank respectively, and enjoy music while charging simultaneously.
  • Dual-Way Power Supply for Enhanced Audio Quality — The TC05M3 seamlessly connects your smartphone, DAC/amp, and power bank at the same time. With consistent voltage and current output delivered to the DAC/amp, it unlocks the full potential of audio decoding and op-amp chips — resulting in superior, stable sound performance throughout your listening session.
  • Reinforced Construction with Longer, Thicker Cables — Simultaneously powering and decoding audio is a high-intensity usage scenario that demands a robust cable. The TC05M3 features oxygen-free copper cores twisted together, wrapped in a double-layer shield of aluminum foil and cross-weave braided mesh, with an aging-resistant, highly transparent PVC outer insulation for long-term durability.
  • 10W Charging Support — The end labeled “10W” connects to chargers and power banks, supporting up to 10W input. When a charging device is connected, the simultaneously connected audio output device consumes almost no power from the phone. (Tested: Samsung S25 Ultra + TC05M3 + TC44Pro E3 recorded max. 10.5W output; Samsung S25 Ultra + TC05M3 alone recorded max. 10.0W output.)
  • Lightweight Yet Durable Plugs — Operating three plugs simultaneously makes plug weight a critical factor. The TC05M3 features a newly developed lightweight USB-C mold, injection-molded with high-strength PC+ABS and reinforced with an aluminum alloy outer ring — achieving a lightweight build without compromising durability or grip.
