Belkin USB-C to 3.5mm Audio Adapter with USB-C Charging

Belkin ROCKSTAR is a compact USB-C adapter that gives one device simultaneous 3.5mm audio output and pass-through USB-C charging up to 60W.

Many modern phones and tablets ship without a headphone jack — the Belkin ROCKSTAR solves that by combining a high-quality digital-to-analog audio path with a USB-C power input so you can listen and charge at the same time. It includes both the ROCKSTAR 3.5mm Audio and a USB-C Charge Adaptor, works with a wide range of phones and tablets, and carries a two-year limited warranty plus REACH certification for safer materials.

How does this adapter let me listen and charge simultaneously?

Plug the ROCKSTAR into your device’s single USB-C port. The adapter routes digital audio through an internal DAC to the 3.5mm jack while a separate USB-C port accepts charging power, so audio playback and battery replenishment occur at once.

• Dual-port design: one USB-C input plus one 3.5mm audio output.
• Built-in digital-to-analog converter for clean headphone audio.
• Pass-through charging while audio is active — no interruptions to playback.

What audio quality and compatibility should I expect?

The adapter uses high-quality components and a DAC to minimize static, dropouts, and interference, delivering clear sound for music and calls. It's broadly compatible with recent USB-C smartphones and tablets from Apple, Samsung, Google, Huawei, LG, Sony and other manufacturers listed on the packaging.

• High-fidelity audio with reduced noise and no static feedback.
• Supports headphones and headsets using a standard 3.5mm plug.
• Compatible devices include Pixel, Galaxy S/Note series, iPad Pro/Mini, OnePlus, LG G6, Sony Xperia and more.

How fast will my device charge through this adapter?

When paired with a USB Power Delivery or Quick Charge 2.0 compatible wall charger and a device that supports higher wattage charging, the ROCKSTAR can pass through up to 60W of power. That makes it suitable for fast charging many smartphones and even some tablets while you listen.

• Up to 60W pass-through charging with a suitable charger and compatible device.
• Works with most USB-C chargers that support Power Delivery or Quick Charge 2.0.
• Maintains audio playback while charging — ideal for heavy daily use or travel.

Is the ROCKSTAR durable and travel friendly?

The adapter is designed for everyday portability with a small footprint that fits in pockets or travel bags. Belkin builds it to meet safety and material standards, and the included two-year limited warranty adds a layer of coverage for typical consumer use.

• Compact, lightweight design that’s easy to stash in a bag or pocket.
• REACH-certified materials for responsible manufacturing choices.
• Two-year limited warranty for peace of mind during regular use.

Who is this for: The Belkin ROCKSTAR USB-C to 3.5mm plus charging adapter is ideal for users who own USB-C-only phones or tablets and want to keep using wired headphones while charging. It’s especially useful for commuters, frequent travelers, and anyone who prefers wired audio for calls or music and needs reliable, fast charging at the same time.
