DDHiFI TC28i Pro Lightning轉USB-C及電源轉接器

Plugged it in while streaming lossless and the background noise floor dropped noticeably—the phone stopped feeding that dirty current into the DAC. The dual connection keeps charging stable at full speed, so no more battery drain anxiety during long listening sessions.

The USB decoding chip finally gets stable power instead of draining my phone's battery mid-session, and I can actually hear the difference in the low end. It's a compact little brick that doesn't block the next port either, which surprised me.

The plug fits snugly and the power pass-through actually works without any static noise. My portable DAC now gets clean power and my phone battery isn't draining as fast during long listening sessions.
