LUOM BT70 Bluetooth FM Transmitter 1.7" LCD QC3.0 2.4A Dual USB TF Card

Car Bluetooth FM Transmitter

The LUOM BT70 plugs into a 12-24 V socket and adds wireless audio streaming plus hands-free calling to any vehicle stereo. A 1.7 inch LCD shows the song name, incoming number and the car battery voltage at start-up. The screen sits on a 270-degree gooseneck so you can angle it for glare-free viewing. Dual USB ports deliver a QC3.0 fast-charge outlet and a smart 2.4 A port that detects the connected device.

Drivers who want simple wireless audio

This unit suits motorists needing Bluetooth music, clear calls via CVC noise cancellation and simultaneous charging for two phones or tablets. It also plays MP3 or WMA files directly from a TF card up to 32 GB in FAT format. Buyers whose factory stereo lacks an FM tuner or an auxiliary input will not be able to route the audio signal.

32 GB TF card limit and dual charging headroom

The transmitter comfortably handles a 32 GB micro SD card loaded with MP3 or WMA tracks and keeps two devices powered — one at QC3.0 rates of 3 A at 3.5-6.5 V, 2 A at 6.5-9 V or 1.5 A at 9-12 V, the other at a steady 5 V 2.4 A. Storage runs out beyond 32 GB and the FM signal can be switched off by holding the next-track key for five seconds while charging continues.
