QOLTEC 2-in-1 USB-C Adapter with USB-C PD 15W and 3.5mm Jack, 10 cm, Aluminum

QOLTEC 2-in-1 USB-C Adapter with USB-C PD 15W and 3.5mm Jack, 10 cm, Aluminum is a compact adapter that combines a USB-C power delivery pass-through port and a 3.5 mm audio jack in a single aluminum housing. The adapter is designed to allow simultaneous charging and use of wired headphones or an auxiliary audio connection when a device’s single USB-C port would otherwise force a choice between power and audio. Its 10 cm cable and lightweight aluminum casing are intended for mobile use and easy storage.

Advantages

The adapter provides power delivery pass-through up to 15W while maintaining a separate 3.5 mm analog output for headphones or line-in connections. Its aluminum construction offers improved durability and heat dissipation compared with plastic housings. The short 10 cm cable balances portability with convenient reach, and the compact footprint makes it suitable for travel or daily commuting. The product supports simple plug-and-play operation without additional drivers on most modern laptops, smartphones, and tablets that support USB-C audio or analog headphone output via an adapter.

Suitable for

• Charging a USB-C device while using wired headphones or external speakers
• Smartphones and tablets with a single USB-C port and no dedicated headphone jack
• Laptops and ultrabooks that support USB-C audio output and need simultaneous power
• In-car audio systems or portable DACs requiring a 3.5 mm connection alongside charging
• Travel, commuting, and desk setups where space and cable management are important

How to use

Plug the adapter’s USB-C male connector into the device’s USB-C port. Connect a USB-C PD charger to the adapter’s USB-C pass-through port to provide up to 15W of charging power while the device remains connected. Insert wired headphones or an auxiliary cable into the 3.5 mm jack to route audio to external headphones or speakers. No drivers are typically required; however, device-specific settings or permissions may need to be adjusted to select the external audio output on some smartphones, tablets, or computers.

Usage recommendations

Use a compatible USB-C power adapter that provides stable output within the adapter’s 15W pass-through limit. For best audio performance, use quality shielded 3.5 mm cables and avoid connecting high-impedance studio headphones that may require a dedicated headphone amplifier. If audio or charging does not function as expected, check device compatibility with USB-C audio/adapters and update system software or drivers where applicable.
