Dual-Port Fast Charging

The ESTONE BC63 is an FM transmitter that plugs into a 12V to 24V vehicle socket and adds Bluetooth 5.0 audio streaming plus three USB charging ports. It accepts USB flash drives and TF cards up to 64GB for local music playback. The dual digital-tube display shows battery voltage, FM channel and Bluetooth status at a glance. Drivers who need hands-free calling and multiple device charging from a single outlet will find it practical.

Sustained Voltage Tolerance

The unit is rated for continuous operation between 12V and 24V and withstands an extreme input range of 10V to 26V without shutting down. This wide window protects charging sessions during engine cranking or alternator fluctuations. Both the QC 3.0 port and the USB-C PD 18W port maintain their negotiated voltages across that range, so connected phones and tablets keep charging at speed. The third USB port stays at 5V/1A for lower-draw accessories.

FM Band Constraints

Audio reaches the car stereo through an FM broadcast signal, so clarity depends on finding an unused frequency in the local spectrum. Urban areas with dense station packing may limit usable channels and introduce interference. The transmitter does not connect via auxiliary cable or digital link, so sound quality is bounded by analogue FM modulation. Buyers who require a direct wired connection or digital audio path should consider a different solution.

Questions about this item

Does the BC63 run hot or drain the battery when it stays plugged in all day?

It draws power from the 12 V-24 V socket and tolerates 10 V-26 V extremes, so normal daytime use adds no noticeable heat or drain.

What must my car already have for the BC63 to work?

A 12 V or 24 V accessory outlet and an FM radio to receive the Bluetooth 5.0 audio signal.

Will the BC63 charge my older phone that only takes 5 V 1 A?

Yes — the third USB port delivers exactly 5 V/1 A and also reads U-disks up to 64 GB.
