ddHifi TC28 Max

Product information "ddHifi TC28 Max"
USB OTG Adapter with PD Input 

  • 60W PD Fast Charging Support 
  • Dual-Way Stable Power Supply 
  • Enhanced Audio Performance 
  • Aerospace-Grade CNC Aluminum Housing 
  • Compact and Durable Design 
  • 4-Layer Gold-Plated PCB 
  • 10,000-Cycle USB-C Port 

Designed to Solve Power & Playback Limitations 
The TC28 series was created to address a common issue among mobile audio enthusiasts: when using USB DAC/amps with smartphones, the device’s USB port becomes occupied, preventing simultaneous charging and causing battery anxiety. TC28Max introduces a major upgrade with support for up to 60W PD fast charging, far surpassing the previous 10W maximum, ensuring uninterrupted high-resolution playback even during extended listening sessions. 

Dual-Way Power Supply for Improved Audio Performance 
TC28Max enables your smartphone, DAC/amp, and audio system to operate together seamlessly. With stable voltage and current delivered to your DAC/amp, its decoding chips and op-amps perform at optimal efficiency—resulting in cleaner dynamics, reduced distortion, and improved overall sound quality compared to direct phone-powered setups. 

Aerospace-Grade CNC Metal Housing 
Built with reliability in mind, TC28Max features a compact chassis crafted from CNC-machined aluminum alloy. The top and bottom covers use a screw-free snap-fit assembly, creating a structure that is lightweight, rigid, and durable enough for daily portable use. 

Compact Size, Robust Internal Architecture 
Despite its compact footprint, the TC28Max incorporates a highly sophisticated internal design, featuring USB PD3.1 support with triple 6-channel DRP USB-C and PD communication modules, an AOS MOS power-switching system capable of handling up to 10A, and multiple built-in protections including reference-voltage control, over-temperature safeguards, current limiting, and short-circuit protection. Its 4-layer immersion-gold PCB offers superior anti-interference stability, while the USB-C female port is rated for 10,000 insertion cycles. Altogether, this architecture ensures stable, efficient, and secure power delivery for any portable Hi-Fi setup.
