## Description

Specifications Model: TC28i Pro Plug type: L OTG plug Size: 20.5x18.4x9.5(mm) Weight: 6.3g USB-C Female Socket1: For connecting audio decoding equipment USB decoder and amplifier USB-C Female Socket2: Charging interface for connecting charger or power bank, support 5V/1A MAX

Review: Perfect OTG adatper - I definately love this adatper. I can keep my old iphone being charged while using it as a dedicated apple music player. About charging, I noticed that you can't use high current charger, 5V 2.5A usb charger is fine. Higher than that, charging won't start.
Review: works ok until it doesn’t - this is one of those products that seems cool on paper but not super impressive in practice. the audio signal sent out the right usb port sounds fine when sent to the dac, no noticeable additional noise or whatnot. that said there wasn’t really any difference between it and any much cheaper usbc to lightning plug adapter you can get for 1/10th the price the charging port stopped working within the first week. I thought about replacing but am just going to return since manufacturer defects seem pretty common with the product also the 90 degree angle really isn’t that helpful. if you use a line silencer which are typically closer in width to a usba plug, they don’t fit most phones with a case on. end up needing to plug in an extender cable which kinda defeats the point

### ⭐ No longer charges
*by J***L on August 27, 2024*

Worked fine at first, charged the phone and powered my DAC at the same time. After about 10 uses over a month, the charging port has failed and it'll only works with low-powered DACs.
