Vehicle power integration

The ESTONE BT70 plugs into a 12-24 V socket and adds Bluetooth streaming, hands-free calling and dual USB charging. It suits drivers who want audio from a phone or TF card played through the factory FM radio without replacing the head unit. The 1.7 inch LCD shows track names, caller ID and vehicle battery voltage at start-up. A 270-degree gooseneck lets you position the screen for clear visibility.

Upgrade from basic chargers

It replaces a simple lighter-socket charger that only supplies power and lacks audio or display functions. The jump is worth it when you need FM transmission for music or navigation prompts, hands-free calls with Siri or Google Assistant, and simultaneous charging of two devices. The orange QC3.0 port delivers 3.5-6.5 V at 3 A, 6.5-9 V at 2 A or 9-12 V at 1.5 A, while the blue port provides 5 V at 2.4 A.

Sustained operation behaviour

Under continuous use the transmitter maintains FM output while both USB ports supply their rated currents. The LCD backlight remains on to show battery voltage and media information throughout the journey. TF cards up to 32 G in FAT format are supported for standalone music playback without a paired phone. The gooseneck holds its angle during vibration so the display stays readable.

Questions about this item

Will the 270-degree gooseneck clear my dashboard vents and 12-24 V socket?

The flexible gooseneck rotates 270 degrees so you can angle the 1.7-inch LCD away from vents and keep the 12-24 V plug seated.

Which USB port do I use first for QC3.0 fast charging and how do I avoid slow charging?

Plug the device that supports QC3.0 into the orange port (3.5-6.5 V 3 A, 6.5-9 V 2 A, 9-12 V 1.5 A); use the blue port for standard 5 V 2.4 A charging.

How often should I reformat the 32 G TF card to keep music playback reliable?

Reformat the card to FAT on a computer every few months or if tracks skip; the transmitter reads FAT-formatted cards up to 32 G.
