Car FM transmitter with Bluetooth hands-free

The Ruth's sister X8 plugs into a 12-24 V vehicle socket and streams audio from a paired phone or a TF card to the car radio over FM. An LED screen shows the active frequency, track number and operating status. Dual USB ports deliver up to 3.1 A and 1.0 A for simultaneous device charging while playback continues.

LED screen and dual USB charging change daily use

The built-in display lets the driver confirm the FM channel and current song without handling the phone. Two USB 2.0 outputs keep a phone and a second device powered during long trips, and the unit remembers its last frequency after the ignition is switched off. A noise-reduction circuit improves call clarity for hands-free conversations.

12-24 V DC input voltage decides compatibility

This transmitter only operates from a 12 V or 24 V vehicle power socket, so it suits most cars, vans and trucks but cannot be used with household mains or USB-C power banks. Buyers needing a battery-powered or home-audio Bluetooth adapter must choose a different product.

Questions about this item

Will the dual USB 2.0 ports or the TF card slot need replacement after extended use?

The dual USB 2.0 ports and TF card slot are solid-state interfaces with no moving parts, so they do not wear out under normal operation.

What limit appears first when the transmitter runs continuously on a 12V or 24V vehicle system?

The 3.1 A charger port and 1.0 A data port share the DC 12-24 V input, so total current draw is capped at 3.1 A before voltage drops or thermal protection activates.

How much heat or fan noise does the unit produce when powered all day?

The ABS-bodied transmitter has no fan; it relies on passive convection, so it generates only modest warmth and stays silent during continuous use.
