In-Car Bluetooth FM Transmitter
The ESTONE BT70 plugs into a 12-24 V vehicle socket and streams audio to the car radio via FM. It suits drivers who want hands-free calls and music playback from a phone or TF card without replacing the factory stereo.
Charging Limits and Card Capacity
Two USB ports deliver power simultaneously: an orange QC3.0 port at 3.5-6.5 V 3 A, 6.5-9 V 2 A and 9-12 V 1.5 A, plus a blue 2.4 A port fixed at 5 V. TF or micro SD cards are accepted only in FAT format up to 32 G.
Adjustable Display and Power-Off
A 1.7 inch LCD with backlight shows track titles, caller ID and vehicle battery voltage at start-up. The screen rotates through 270 degrees on a gooseneck for comfortable viewing. Holding the next-track button for five seconds disables the FM transmitter while keeping the charging ports active.
