ESTONE BT70 Bluetooth FM Transmitter 1.7 Inch Display QC3.0 2.4A Dual USB TF Card

Vehicle Power Fit

This Bluetooth FM transmitter plugs into a 12-24 V socket and adds hands-free calling plus music streaming to any car or RV. Two USB ports charge phones or tablets while the 1.7 inch LCD shows track names, caller ID and the vehicle battery level. A 270-degree gooseneck lets you angle the screen for clear visibility.

Socket and Storage Check

Verify that your vehicle provides a 12-24 V power outlet before ordering. The TF card slot accepts FAT-formatted cards up to 32 G for offline playback. No auxiliary input or wired audio connection is included, so audio routes exclusively through the FM signal.

Sustained Use Behaviour

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 fast charging during long drives. The blue 2.4 A port supplies 5 V at 2.4 A for a second device simultaneously. Both ports maintain output while the transmitter broadcasts audio continuously.
