FM Transmitter with 1.7 Inch Display

The ESTONE BT70 is an FM transmitter that adds Bluetooth audio streaming and hands-free calling to any vehicle with a 12‑24 V power outlet. A 1.7 inch LCD shows the song name, incoming call number and the car battery voltage at start-up. The screen sits on a 270‑degree gooseneck so the driver can set the viewing angle without tools. Power is drawn directly from the socket, leaving no cables across the dashboard.

Drivers who need Bluetooth audio

This unit suits motorists who want wireless music, clear calls and simultaneous charging for a phone and a tablet. It reads audio files from a TF or micro SD card up to 32 GB in FAT format, so a smartphone is not required for playback. Buyers whose vehicle lacks a 12‑24 V accessory socket or who need an integrated DAB tuner will not find those functions here.

QC3.0 and 2.4 A dual USB charging

The orange QC3.0 port delivers 3.5‑6.5 V at 3 A, 6.5‑9 V at 2 A and 9‑12 V at 1.5 A for compatible fast‑charge devices. The blue port supplies a steady 5 V at 2.4 A with automatic current detection for standard USB gear. Both ports operate together, allowing two devices to charge at full rated speed from a single transmitter.

Questions about this item

Will the QC3.0 port need replacement after heavy use?

The QC3.0 port delivers 3 A at 3.5–6.5 V, 2 A at 6.5–9 V and 1.5 A at 9–12 V; no maintenance schedule is defined for the port itself.

What limits charging speed when both USB ports run continuously?

The blue port is capped at 5 V / 2.4 A and the orange QC3.0 port steps down to 1.5 A above 9 V, so total output is shared between the two ports.

How hot does the 1.7 inch display get during all-day operation?

The display is mounted on a 270-degree gooseneck that keeps it away from direct dashboard heat; the unit only shows the car battery voltage at start-up.
