Jansicotek BC71 Bluetooth 5.0 FM Transmitter

The Jansicotek BC71 adds Bluetooth 5.0 streaming and hands-free calling to any vehicle with an FM radio. It transmits audio across the 87.5 MHz to 108.0 MHz band and plays lossless files from a TF card up to 64 GB. A dual digital display shows battery voltage in real time while colorful LED backlights provide cabin ambience.

Upgrade from basic chargers or older adapters

This unit replaces a simple USB charger by adding 18 W Power Delivery and 18 W Quick Charge 3.0 ports for a combined 36 W output. The jump is worth it when you need to fast-charge two phones simultaneously while streaming music or taking calls. Drivers whose factory stereo lacks an auxiliary input gain wireless audio without dashboard modification.

Stable output during long journeys

Bluetooth 5.0 maintains a steady link for hours of playback and the CVC noise-reduction microphone keeps voice calls clear at motorway speeds. The FM signal stays strong across the full frequency range and the independent charging circuit delivers full power even while audio is streaming. The LED display can be switched off to reduce night-time distraction without interrupting power delivery.
