UGREEN Aux Bluetooth 5.4 Adapter for Car

This compact car Bluetooth adapter brings wireless audio and hands-free calling to vehicles with a 3.5mm aux input and a powered USB-A port, allowing drivers to stream music and manage calls without replacing the stereo. It uses Bluetooth 5.4 for a more stable connection according to the manufacturer, and the built-in microphone supports hands-free conversations while on the move.

Key Points

The adapter supports dual connection so two devices can be paired at once, with calls taking priority over music playback. A multifunction button with an RGB indicator lets you answer calls, control playback and toggle the light effect, and the braided cable and small form factor make the unit easy to position and carry. Note that automatic reconnection may not be supported by some phones such as Galaxy models and iPhone, so manual re-pairing could be required.

Technical Specifications

• Bluetooth version: 5.4
• Input interfaces: USB-A (power) and 3.5mm audio jack

Usage Recommendations

Plug the USB-A connector into a powered port in the vehicle and insert the 3.5mm jack into the car aux socket for immediate use. Keep the multifunction button pressed for about five seconds if you need to change the RGB indicator behaviour. For clearer sound, connect directly to the car’s audio input when possible rather than via additional converters or adapters.

Positive Aspects

The Bluetooth 5.4 link aims to reduce latency and maintain a steady wireless stream while driving, which can improve music playback and call stability. The compact design and included 3M stickers let you mount the adapter in a convenient location, preventing loose cables and reducing clutter. A minor limitation to consider is that some phone models may require manual reconnection after initial pairing according to the manufacturer, which can interrupt seamless switching between devices.
