Car FM Transmitter with 3.5mm AUX, 200 Frequencies, Black

This car FM transmitter offers a practical audio link for vehicles without Bluetooth or a direct auxiliary input. It connects to a phone, tablet or portable player through a 3.5mm headphone jack and broadcasts the audio over a selected FM frequency, which you then tune into on your car radio. The device uses digital PLL phase-locked loop technology and covers the 87.5-108.0MHz band, with up to 200 selectable frequencies. An LCD display shows the chosen frequency, and power-off memory retains the last used channel. The built-in 120mAh lithium battery is rechargeable, and the stated launch distance is 15 metres. It is suitable for devices with a 3.5mm headphone jack, including iPad, iPhone (3G) and other compatible players. The transmitter is black and does not contain a microphone; hands-free calls use the phone's own microphone.

Features and Construction

The transmitter is designed around a wired 3.5mm connection and FM broadcasting. Its main electronic specifications include a frequency range of 87.5-108.0MHz, an audio input response of 100-15000Hz and stereo resolution of ≥38dB. The output voltage is 5 ± 0.1 and vehicle current is ≤600mA. These figures describe the operating parameters stated in the source text.

Material and Build

The source text states a built-in 120mAh lithium battery, which is rechargeable. No further materials or construction details are provided. The unit is black. It has an LCD display for frequency and channel selection. The transmitter does not have a microphone, so hands-free calls are made through the phone's microphone when the device is plugged in.

Size and Practical Fit

The stated launch distance is 15 metres. The FM band range is 87.5-108.0MHz, and the audio input response is 100-15000Hz. Working temperature is -10°C to +40°C, and storage temperature is -20°C to +50°C. These measurements describe the operating limits stated in the source text. The 3.5mm plug fits compatible headphone jacks on devices such as iPad, iPhone (3G) and other players.

Uses and Placement

This transmitter is intended for in-car audio playback from a phone or portable device. It can also be used in other settings where a 3.5mm audio source needs to be sent to an FM radio. The connection is wired, so the device remains plugged into the audio source during use. The launch distance of 15 metres gives some flexibility in placement within the vehicle.

Event or Professional Use

Beyond everyday driving, the transmitter can be used in any situation where a 3.5mm audio source needs to reach an FM radio, such as in a van, truck or older vehicle without built-in Bluetooth. The hands-free function allows calls to be taken through the car speakers, but the phone's microphone must be used because the transmitter has no microphone. The power-off memory helps retain the chosen frequency between uses.

Everyday Home Use

The transmitter can also be used indoors with a compatible FM radio, for example to play audio from a phone or tablet through a radio in another room. The 3.5mm connection works with iPad, iPhone (3G) and other devices with a headphone jack. The LCD display makes frequency selection straightforward, and the rechargeable 120mAh battery supports cordless operation.

Benefits and Buying Value

This product provides a way to add audio playback to a car radio without replacing the head unit. It uses a standard 3.5mm connection and FM broadcasting, both of which are widely understood. The 200 selectable frequencies and power-off memory reduce the need to reset the channel each time. The built-in rechargeable battery avoids the need for disposable batteries.

Reuse and Low Maintenance

The built-in 120mAh lithium battery is rechargeable. The power-off memory stores the last used frequency, so the device is ready for the next journey without re-tuning. No specific maintenance instructions are provided in the source text beyond normal use within the stated temperature ranges. The transmitter can be used with any device that has a 3.5mm headphone jack.

Why Choose This Product

This transmitter is suitable for drivers who want a simple wired audio connection to their car radio. It supports hands-free calls through the car speakers when used with the phone's microphone. The LCD display and 200 selectable frequencies give flexibility in finding a clear channel. The stated launch distance is 15 metres. It is a practical option for vehicles without Bluetooth or an auxiliary input.
