EOIWUY Upgraded Bluetooth Car Adapter 5.3 with PD36W

This Bluetooth car adapter combines wireless audio, hands-free calling and fast device charging in one compact unit, aimed at drivers who want clearer sound and quicker power on the move. It uses Bluetooth 5.3 for stable connectivity and includes both PD36W and QC3.0 ports to top up phones and tablets while you drive.

Key Points

The adapter supports Bluetooth 5.3 for a reliable connection of up to around 10 metres according to the manufacturer, which helps when stepping in and out of the vehicle without re-pairing constantly. It presents an FM transmitter function so vehicles without modern infotainment systems can stream music and navigation prompts through the car radio. The built-in microphone uses CVC noise reduction to keep voice calls clearer in everyday driving conditions. Ambient LED lighting illuminates controls at night and there is a real-time voltage display that warns if the car battery falls below 11.5V.

Technical Specifications

Advantages

The dual-port fast charging makes it practical for drivers who travel with more than one device, as both phone and passenger device can receive high-speed charging at the same time. The multi-function knob reduces the need to touch your phone while driving, letting you answer or reject calls, redial and trigger voice assistants with minimal distraction. For older cars without USB audio input, the FM transmitter restores access to streaming services and turn-by-turn directions through the existing radio.

Usage Recommendations

Set the transmitter to an unused FM frequency before pairing, then match that frequency on your car radio for best audio quality. Place your phone within the recommended Bluetooth range for stable playback and navigation prompts, and keep an eye on the voltage readout during long idling periods or when using many electrical accessories. Consider that audio quality via FM can vary with local interference and radio reception, so results may differ by location.

Note that, according to the manufacturer, combined charging output reaches 54W when both PD and QC ports are used. The device provides multiple safety protections against overvoltage, overheating and short circuits, which helps protect connected devices during charging.
