Stouchi USB-C to 3.5mm Jack and Charger Adapter (USB-C Aux + PD3.0 fast charging, hi-res DAC)
Product description
At a glance
If you want to keep using 3.5mm headphones while still charging your phone at the same time, this USB-C to 3.5mm Jack and Charger Adapter is designed for that “two jobs at once” setup. It’s a small dongle that combines audio output with USB-C charging support, aiming to remove the annoying trade-off of either listening or topping up battery.
On paper, the pitch is straightforward: hi-res DAC/ADC support up to 96kHz/24bit, plus PD3.0/QC3.0 fast charging up to 30W (with charging speed ultimately depending on your device and charger). It’s not perfect for every scenario, but if you regularly use a wired headset for music, calls, or gaming, it can be a neat everyday fix.
Key features worth knowing
What stands out first is the hi-res audio claim. The adapter uses a high-fidelity DAC chip and also references ADC with 48kHz/24bit, with support described as up to 96kHz/24bit. If you’re the kind of person who notices sound quality differences with higher-spec setups, this is clearly intended to appeal to that side of things.
The second major feature is the 2-in-1 approach: a 3.5mm female socket for Aux headphones and a charging path that lets you listen while charging, without constantly swapping cables. It also mentions a blue light and in-line control support, which matters if you rely on controls on your wired headset.
Tech summary
Here’s what the product description says you should expect from the hardware side:
- Hi-Res DAC/ADC support: up to 96kHz/24bit (DAC) and ADC up to 48kHz/24bit
- Audio output: 3.5mm female socket (Aux-style)
- Headphone compatibility: CTIA and OMTP support
- Charging: PD3.0 and QC3.0, maximum output up to 30W
- Charging power mentioned: max 9V/3A for the adapter
- Cable/build: corrosion-resistant aluminium alloy housing and a nylon-braided cable
- Power style: battery-free, plugs in
One limitation to keep in mind: charging speed is “up to your devices” and the description suggests using a PD wall charger for faster results. That means you could see slower charging than the headline figure if your phone, charger, or cable setup can’t match it.
What it’s like in day-to-day use
In practical terms, this adapter is the kind of thing you’d use on the move: plug it into your phone, connect your 3.5mm headphones, and then connect your USB-C charger so you can listen without the battery anxiety. For example, if you’re commuting with wired headphones and you don’t want to stop the music to find a charging workaround, this is exactly the situation it’s built for.
It’s also positioned for more than music. The description mentions calling and playing games, which is relevant because audio latency and control support can matter in those moments. There’s also mention of Android wire control protocol, so if your wired headset uses standard inline control buttons, it’s designed to work with that style.
Compatibility and requirements
Compatibility is broad across USB-C devices, but it’s worth checking the exact list before you assume it will work perfectly.
The description states compatibility with many Type-C devices including iPhone models (17/16 Pro/Max), Samsung Galaxy S25/S24/S23/S22 and others in the family, iPad Air/Pro/Mini, Pixel devices (including Pixel 7), and several other brands. It also explicitly notes it does NOT support OnePlus.
If you happen to be using an unsupported device, this is where things can fall apart quickly—because adapters like this are usually strict about device compatibility.
Is it worth it?
Buy it if you want a single dongle to cover both wired 3.5mm audio and charging at the same time, and you’re specifically looking for a solution that references hi-res DAC support. It suits people who keep a wired headset around for everyday listening, calls, or gaming and want to avoid the “disconnect to charge” routine.
Skip it if your main priority is charging speed regardless of everything else, because the adapter’s fast charging performance is dependent on your phone and the charger you use (PD wall charger is suggested for faster results). Also consider avoiding it if your phone is OnePlus, since the description says it isn’t supported.
Mini FAQ
Does the adapter let me listen while charging?
Yes. The description is clear that it’s meant to charge while you’re listening, so you don’t have to choose between audio and power.
What charging standard does it support?
It mentions PD3.0 and QC3.0 fast charging, with an output up to 30W, but charging speed depends on the device.
Will it work with different headphone types?
It claims compatibility with CTIA and OMTP headphones, which covers a common split in headphone wiring standards.
Does it require a battery?
No, it’s described as battery-free and “plug and play”.
What should I double-check before buying?
Double-check your device compatibility (especially if you’re using OnePlus) and make sure you have a PD wall charger if you’re aiming for the faster charging behaviour described.
