Product identity

The Jansicotek BT70 is a Bluetooth FM transmitter that plugs into a 12 to 24 volt vehicle socket and adds hands-free calling plus wireless audio streaming to any car stereo. Drivers who want a simple way to play music from a phone or memory card without replacing the factory radio will find it fits the need.

Charging limits

Two USB ports share the output: an orange QC3.0 port delivers 3.5 to 6.5 volts at 3 amps, 6.5 to 9 volts at 2 amps or 9 to 12 volts at 1.5 amps, while a blue port supplies a fixed 5 volts at 2.4 amps. The combined draw is capped by the vehicle socket, so simultaneous fast charging and high-volume playback can reach that ceiling.

Storage headroom

A TF or micro SD card formatted in FAT is accepted up to 32 gigabytes and plays MP3 or WMA files in folder order. Larger cards or other file systems are not recognised, so users with bigger libraries must switch to a phone or USB stick connected via Bluetooth or the 3.5 millimetre AUX link.

Questions about this item

Should I use the orange QC3.0 port or the blue 2.4 A port for my phone?

Use the orange QC3.0 port for devices that support Quick Charge 3.0; it delivers 3.5-6.5 V at 3 A, 6.5-9 V at 2 A, or 9-12 V at 1.5 A. The blue port provides a fixed 5 V at 2.4 A for standard charging.

What does the 1.7 inch LCD show while I am driving?

The backlit screen displays the current song name, incoming call number, and the vehicle battery voltage at start-up; the 270-degree gooseneck lets you angle it for clear visibility.

How much music can I store on a TF card for this transmitter?

The unit reads FAT-formatted micro SD cards up to 32 G, so capacity depends on the card you insert; it plays MP3 and WMA files directly from the card.
