Car FM Transmitter with 3.5mm Aux Audio, LCD Display and PLL Digital Stereo

This car FM transmitter connects to a phone, tablet, or portable player through a 3.5mm headphone jack and sends the audio to a car radio on a selectable FM frequency. It uses DIGITAL PLL phase-locked loop technology for high-fidelity stereo, and the LCD display makes frequency and channel selection straightforward. The FM band range is 87.5-108.0MHz, with up to 200 selectable frequencies. The transmitter supports hands-free calls by sending the caller's voice through the car audio, using the connected phone's microphone, as the transmitter itself does not have a built-in microphone. It is designed for drivers who want to play music and take calls through their existing car stereo without replacing the head unit.

Features and Construction

The transmitter combines a 3.5mm audio input, an LCD display, and a built-in rechargeable battery in a compact unit. These features support in-car listening and hands-free calls using the connected device's microphone. The design focuses on easy frequency matching and clear channel selection.

Material and Build

The unit has a built-in 120mAh rechargeable lithium battery and an LCD display for showing the selected frequency. It uses DIGITAL PLL phase-locked loop technology to support high-fidelity stereo output. The transmitter itself does not include a microphone, so hands-free calls rely on the connected phone's microphone. The source text does not provide further details on housing material or construction, so no additional material claims are made.

Size and Practical Fit

The transmitter connects through a 3.5mm headphone jack, making it suitable for iPads, iPhones (3G), Android phones, and other players with a compatible port. Its output voltage is 5 ± 0.1V and vehicle current is ≤600mA. The launch distance is 15 metres, and the FM band range is 87.5-108.0MHz with up to 200 selectable frequencies. These figures give a clear idea of its in-car reach and tuning options.

Uses and Placement

This transmitter is intended for use in a car, where it connects a portable audio device to the car radio via FM transmission. It can be used for music playback and hands-free calls, provided the phone or device has a 3.5mm headphone jack and the car radio can receive FM signals.

Event or Professional Use

For drivers who need to take calls while on the road, the transmitter sends the caller's voice through the car audio system. The hands-free function works through the phone's microphone, not a microphone in the transmitter. The LCD display and power-off memory help retain the last used frequency, which can reduce setup time between journeys. The 15-metre launch distance supports use within the vehicle.

Everyday Home Use

The transmitter can also be used outside the car with any device that has a 3.5mm headphone jack and a nearby FM radio. For example, it can connect an iPad or iPhone to a compatible FM radio. The 87.5-108.0MHz band and up to 200 selectable frequencies allow you to find a clear channel. The built-in 120mAh lithium battery is rechargeable, so it does not rely on the car's power outlet.

Benefits and Buying Value

The main practical benefits are easy connection, selectable frequencies, and memory of the last used channel. The transmitter uses PLL digital technology for stereo sound and provides an LCD display for frequency selection. It supports hands-free calls through the phone's microphone and offers a 15-metre launch distance.

Reuse and Low Maintenance

The built-in 120mAh rechargeable lithium battery can be recharged, so the transmitter can be used repeatedly without disposable batteries. The power-off memory stores the last used frequency, which can simplify reconnection. The source text does not provide specific care or maintenance instructions beyond general use, so no specialist maintenance claims are made. Keeping the unit within the stated working temperature range of -10°C to +40°C is advised.

Why Choose This Product

This transmitter suits drivers who want to play audio from a 3.5mm-equipped phone or player through their car radio and take hands-free calls using the phone's microphone. It offers up to 200 selectable frequencies, an LCD display, 15-metre launch distance, and a built-in rechargeable battery. The black colour and compact design make it easy to keep in the car. It is not suitable for devices without a 3.5mm headphone jack unless an appropriate adapter is used, and the source text does not specify such an adapter.
