DDHIFI TC28Max USB-C OTG Adapter with PD Input

Power Upgrade: Supports up to 60W PD fast charging, enabling simultaneous charging and high-resolution audio playback without interruption.

Designed to Solve Power & Playback Limitations

The TC28Max is designed specifically for mobile Hi-Fi users who rely on USB DAC/amps. Traditional OTG connections occupy the smartphone’s USB-C port, preventing charging and leading to battery anxiety during extended listening sessions.

TC28Max eliminates this limitation by introducing high-power PD charging alongside stable OTG audio output, ensuring uninterrupted playback even during long-term use.

60W PD Fast Charging Support

Compared to earlier generations limited to 10W charging, TC28Max supports up to 60W PD fast charging, keeping your smartphone powered while driving USB DAC/amps at full performance.

Dual-Way Stable Power Supply

TC28Max enables your smartphone, DAC/amp, and audio system to operate together seamlessly. With stable voltage and current delivery, decoding chips and op-amps inside your DAC perform at optimal efficiency.

The result is cleaner dynamics, reduced distortion, and improved overall sound quality compared to phone-powered setups.

Aerospace-Grade CNC Aluminum Housing

Built for durability and daily portability, TC28Max features a compact chassis crafted from CNC-machined aluminum alloy.

The screw-free snap-fit top and bottom covers create a lightweight yet rigid structure, delivering both premium feel and long-term reliability.

Compact Size, Robust Internal Architecture

Despite its small footprint, TC28Max integrates a highly sophisticated internal design:

  • USB PD 3.1 support with triple 6-channel DRP USB-C & PD communication modules
  • AOS MOS power-switching system supporting up to 10A current
  • 4-layer immersion-gold PCB for superior anti-interference stability
  • USB-C female port rated for 10,000 insertion cycles

Comprehensive Protection System

TC28Max incorporates multiple safety mechanisms to ensure stable and secure operation:

  • Reference-voltage control
  • Over-temperature protection
  • Current limiting
  • Short-circuit protection

These safeguards ensure reliable performance for any portable Hi-Fi setup.
