FM transmitter BLOW 74-170 — Bluetooth 5.0, QC3.0 fast charge, PD 20W

BLOW 74-170 is an FM transmitter that combines Bluetooth 5.0 wireless audio streaming with integrated fast-charging ports (QC3.0 and PD 20W). The device connects to a smartphone via Bluetooth, transmits music and navigation prompts to a car radio over an FM frequency, and supports hands-free calls through the car audio system. It is designed for vehicles without built-in Bluetooth or modern infotainment systems and provides both audio connectivity and rapid charging in a compact, plug-in form factor.

Advantages

The transmitter uses Bluetooth 5.0 for stable wireless connection and reduced audio dropouts, while the FM transmission enables compatibility with virtually any car radio. Integrated QC3.0 and PD 20W ports deliver fast charging for compatible smartphones and accessories without requiring separate adapters. Built-in call handling and media controls allow safer, convenient control of phone functions from the car cabin. The compact design plugs into the vehicle power socket and occupies minimal space.

• Cars without factory Bluetooth or auxiliary input
• Drivers who need hands-free calling via the car audio system

How to use

Insert the FM transmitter into the vehicle power socket and set the device to an unused FM frequency. Pair your smartphone with the transmitter using Bluetooth 5.0 from the phone's Bluetooth menu. Tune the car radio to the same FM frequency to receive audio. Use the transmitter controls or the phone to play music or navigation prompts; incoming calls will route through the car speakers and can be answered using the transmitter's call control. Connect a USB device to the QC3.0 or PD port to charge while driving.

Usage recommendations

For best audio quality, choose an FM frequency with minimal local radio interference and place the transmitter where the built-in microphone can clearly pick up the driver's voice. Use a PD-compatible cable for optimal 20W charging performance and ensure your phone supports the fast-charge standard used.
