Bluetooth 5.0 car adapter for 12 V–24 V vehicles

The LUOM BC63 plugs into a cigarette-lighter socket and pairs with any Bluetooth 5.0 device to stream audio through the car FM radio. It also works with TF cards and USB drives up to 64 GB, giving drivers multiple playback options without replacing the factory head unit. Hands-free calls and voice-assistant access are handled through the built-in microphone.

Operates from 10 V to 26 V with three charging ports

The transmitter draws power from the vehicle electrical system and remains functional across the full 10 V–26 V range. A USB-C PD port delivers up to 18 W, a QC 3.0 port supplies 5 V/3 A, and a third USB port provides 5 V/1 A for media storage. No active cooling is used, so operation stays silent.

Knob control and dual digital display for daily use

A top-mounted rotary knob adjusts FM frequency between 87.5 MHz and 108 MHz, sets volume, and changes tracks without touching a phone. Dual digital tubes show the selected channel, vehicle voltage, and Bluetooth status at a glance. Colorful LED backlighting adds visibility in low light, and the compact shape fits most dash layouts without blocking adjacent controls.

Questions about this item

How do I install the BC63 and which step do people often miss?

Plug the transmitter into the 12V-24V cigarette lighter, pair your phone via Bluetooth 5.0, then tune both the device and car radio to the same frequency between 87.5 and 108 MHz — the step most skipped is matching the exact FM channel on both ends.

What maintenance or replacement will the BC63 need over time?

The unit has no user-serviceable parts; keep the contacts clean and ensure the vehicle voltage stays within the 10-26 V extreme range. If the internal fuse blows, replace it with the same rating.

What limit appears first during long drives with the BC63?

Sustained high-current charging on the USB-C PD 18W and QC 3.0 ports can raise internal temperature, triggering thermal protection that reduces output until the transmitter cools.
