Werleo 77W Bluetooth 5.4 FM Transmitter Car Adapter 65W PD3.0 Fast Charging Type-C Spring Cable Black

Werleo 77W FM Transmitter for Non-Bluetooth Cars

The Werleo adapter adds Bluetooth 5.4 audio streaming and dual 65 W USB-C fast charging to any vehicle with a 12 V socket. It targets drivers whose factory stereo lacks wireless connectivity but who still want hands-free calls and music playback from a phone or USB stick.

Bass Boost and Spring Cable Change Daily Use

A hardware bass boost engages automatically on power-up, giving low-end emphasis without an app. The coiled Type-C spring cable retracts to keep the cabin tidy while still delivering the full 65 W PD3.0 rate to each of the two ports, so two devices can charge at their advertised 80 % or 85 % in half an hour.

Plug-and-Play Install with Frequency Hunt

Installation is limited to plugging the unit into the 12 V outlet, tuning the FM frequency to a clear station, and pairing the phone — typically under one minute. The main friction point is finding a vacant FM channel in dense urban areas; if no clean frequency exists, audio quality drops and the transmitter cannot overcome the interference. Buyers who need digital audio input or multi-device Bluetooth multipoint should look elsewhere.
