{"type":"firestarter.listing","listing":{"id":"lst_WbNqjnkL","product_name":"DDHIFI TC28Max","category":"adapter","description":"\n\nDesigned to Solve Power & Playback Limitations\nThe 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.\n\n\nDual-Way Power Supply for Improved Audio Performance\nTC28Max 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.\n\n\nAerospace-Grade CNC Metal Housing\nBuilt 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.\n\n\nCompact Size, Robust Internal Architecture\nDespite 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.\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/TC28Max-JPG01.jpg?v=1765521841","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/TC28Max-JPG07.jpg?v=1765521841","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/TC28Max-JPG05.jpg?v=1765521841","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/TC28Max-JPG02.jpg?v=1765521841","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/TC28Max-JPG03.jpg?v=1765521841","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/TC28Max-JPG04.jpg?v=1765521841"],"price":29.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:44.450Z"},"share_url":"https://firestarter.network/l/lst_WbNqjnkL","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
