54W 4-Port Car Adapter for Bluetooth 5.3 Users

The Auto Ventshade BC91 plugs into a 12 V socket and adds four USB ports plus an FM transmitter. It suits drivers who want fast charging and hands-free calls without replacing the factory stereo. Bluetooth 5.3 handles audio streaming and voice navigation from a paired phone.

Simple Plug-In With a Few Fit Checks

Insert the 24 mm spring-clip connector to a depth of 57 mm; it fits most vehicles but not recessed sockets such as glove-box outlets. To remove, hold the car socket with one hand and pull the adapter with the other to avoid damage. Set the car audio volume below 50 % before pairing to reduce background noise.

FM Transmission and Power Limits

The adapter broadcasts audio over an FM frequency, so reception quality depends on local radio congestion and antenna position. Total output is 54 W split across PD 36 W and QC 18 W ports; charging speed drops when all four ports are used simultaneously. The polycarbonate body weighs 0.068 kg and operates on 12 V DC only.

Questions about this item

How do I know the Bluetooth 5.3 connection is stable after pairing my phone?

Pair your phone, then play audio through the FM transmitter; clear sound without dropouts confirms the link is working.

What comes in the box and what must I buy separately?

The adapter includes the main unit with a 24 mm spring-clip plug and 57 mm depth; you supply your own charging cables and USB drive for media playback.

Which charging ports should I use for a phone that supports PD36W and another that uses QC18W?

Use the PD36W port for the first phone and the QC18W port for the second; the remaining two ports share the total 54 W output for additional devices.
