TC28Max
USB OTG Adapter with PD Input
Broader Compatibility and Faster Charging
The TC28 series was designed to solve a common problem: when using a phone with a DAC/amp for music, the charging port is occupied, which can lead to battery anxiety during extended use. Compared to the TC28C Pro, the TC28Max supports significantly higher charging power, increasing from 10W to a maximum of 60W.
Note: Due to differences in USB interface protocols across various Android phone brands, compatibility may vary when using certain models with TC28Max. Actual test results will be continuously updated in the list at the end of the introduction*.
Dual-Way Power Supply for Enhanced Audio
The TC28Max seamlessly connects your smartphone, DAC/amp, and power bank. It not only charges your phone simultaneously but also delivers stable power to your DAC/amp. This consistent voltage and current output allow the audio decoding and operational amplifier chips to perform at their best, resulting in improved sound quality.
Compact CNC Metal Housing
The reliable performance of the TC28Max stems from its high-quality structural design. The housing is precision-machined from aerospace-grade aluminum using CNC technology. The top and bottom covers are assembled with a screw-free snap-fit process, making the overall structure compact, solid, and highly durable.
Slim Size with Durable Construction
Supports USB PD3.1 protocol, equipped with 3 sets of 6-channel DRP USB-C and PD communication modules.
Features AOS MOS for switch control, independently placed in the circuit to support up to 10A current.
Integrates switch control, reference voltage, error amplification, over-temperature protection, current limiting, and short-circuit protection for safety and reliability.
Utilizes a 4-layer immersion gold PCB for superior anti-interference performance. The USB-C female port is rated for 10,000 insertion cycles.
