Car HD Radio Kit

The ESTONE BC71 is a car HD radio kit that integrates an FM transmitter with dual USB charging ports. It fits factory stereo installations and includes a TF card slot for local media playback. The unit shows real-time battery voltage on a dual digital display.

USB-C PD and QC3.0 Charging

This kit suits drivers who want fast charging from both USB-C PD 18W and USB-A QC3.0 18W ports simultaneously. It is not for buyers who need more than two charging ports or who require a dedicated auxiliary input jack. The maximum combined output reaches 36W.

FM Sensitivity 11.2 dBf

The usable FM sensitivity of 11.2 dBf determines how cleanly the transmitter locks onto clear frequencies between 87.5 MHz and 108.0 MHz. Weak-signal areas may experience more static or dropouts. Buyers in fringe reception zones should test the frequency range before committing.
