1.44" Display FM Transmitter

The Nulaxy KM18 Plus is a Bluetooth 5.4 car adapter that streams audio to your vehicle stereo via FM transmission. It suits drivers of 12V-24V cars and trucks who want hands-free calls and music playback without replacing the factory head unit. A 1.44 inch LCD shows caller ID, frequency and battery voltage.

Flexible Gooseneck & Dual Fast Charging

The rotating gooseneck lets you angle the screen for glare-free viewing while keeping controls within reach. Installation only requires plugging the unit into the 12V-24V socket and tuning the car radio to a clear FM frequency. Two high-output ports — Type-C PD 30W and USB QC3.0 — charge a phone and tablet simultaneously.

48W Total Charging Power

The combined 48W output across both ports is the single figure that determines whether this adapter can fast-charge your specific devices during a journey. If your phone and tablet together demand more than 48W, charging speed will be limited. Buyers needing higher simultaneous wattage should look elsewhere.

Questions about this item

How do I know the FM transmitter is locked on the right frequency after setup?

The 1.44 inch LCD shows the active FM channel so you can confirm the station matches your car radio tuning.

What comes in the box and what must I provide myself?

The adapter includes a flexible gooseneck mount, a Type‑C PD 30W port and a USB QC3.0 port for charging; you supply a TF card or an AUX cable if you want those playback options.

Which charging port should I use for a phone that supports 30 W PD?

Use the Type‑C PD 30W port for the fastest charge; the USB QC3.0 port handles a second device at the same time.
