Compact FM Transmitter With Dual USB-C

This Scosche BC47 plugs into a 12 V accessory socket and adds Bluetooth 5.3 audio streaming plus hands-free calling to any vehicle stereo. Two USB-C ports deliver up to 36 W Power Delivery and 18 W Quick Charge 3.0 simultaneously so a phone and a tablet can fast-charge together. Dual built-in microphones with CVC noise reduction keep voices clear during calls or voice-assistant commands.

For Drivers Who Need One-Device Audio And Power

Suits owners of older cars without factory Bluetooth who want wireless music, navigation prompts and safe calling without replacing the head unit. The single-DIN footprint fits tight dash spaces and the multifunction knob handles calls, volume and FM frequency in one reach. Buyers whose vehicle already offers CarPlay or Android Auto integration will not gain new connectivity from this adapter.

Dual USB-C Fast Charging Up To 54 W Total

The deciding specification is the combined 54 W output split between a 36 W PD port and an 18 W QC 3.0 port. If your devices support those profiles you can recharge a phone and a laptop-class tablet at full speed while streaming audio. If you only need basic 5 W charging or lack USB-C cables, a simpler transmitter will cover the audio job for less money.

Questions about this item

Will the dual microphones on the BC47 need replacing after extended use?

The built-in microphones are fixed components with no user-replaceable parts, so they are intended to last the life of the adapter.

What limits continuous high-power charging from both USB ports at once?

The adapter delivers up to 54W total across PD 36W and QC 18W ports, and the 12V vehicle socket fuse typically caps sustained draw.

How hot does the BC47 get when charging two phones all day?

The plastic housing dissipates heat from up to 54W combined output, and built-in safety circuits protect against overheating during prolonged use.
