Car MP3 Audio Player with Bluetooth and Dual USB Charger for Handsfree Calling

This car MP3 audio player combines a Bluetooth handsfree kit, FM transmitter, and dual USB charger in one compact unit. It addresses the common issue of older car stereos lacking modern connectivity, allowing you to stream music from your phone or a storage device while keeping devices charged. The LED screen and simple controls make it easy to use during drives, and the wide voltage input ensures compatibility with most vehicles.
Features and Construction

Built around a high-speed USB 2.0 interface, this device integrates several practical functions for everyday driving. It delivers reliable charging and audio playback without complicated installation, drawing power directly from the vehicle's cigarette lighter socket.
Dual USB Charging Output
The unit provides two USB charging ports: one with Smart IC technology at 5V 3.1A for faster charging of tablets and phones, and a second at 5V 1A for smaller devices. This lets you charge multiple gadgets simultaneously during your journey.
Audio Playback and Storage
It supports TF cards and U disks up to 32GB capacity, playing files in MP3, WMA, APE, FLAC, and WAV formats. The FM transmitter operates across 87.5-108MHz with a signal-to-noise ratio of 85db (FM: 65db) and harmonic distortion below 0.05% for clear audio transmission within 5 metres.
Bluetooth Handsfree Calling
Bluetooth connectivity enables handsfree phone calls, allowing you to keep both hands on the wheel. The built-in microphone picks up your voice for clear conversation without holding the phone.
Uses and Placement

This device is designed for direct use in almost any car with a 12-24V power socket. Its compact size means it won't obstruct gear sticks or cup holders, making it suitable for daily commutes and long trips alike.
Everyday Commuting
Plug it in to quickly access your music library via Bluetooth or a loaded USB stick. The dual charger keeps your phone and a passenger's device topped up, reducing battery anxiety during the work week.
Long-Distance Travel
On longer drives, the FM transmitter lets you broadcast your own playlist through the car's speakers, while the handsfree function handles navigation prompts and calls. The LED screen shows the current frequency and track information.
Compatibility with Storage Media
With support for both TF cards and U disks up to 32GB, you can use whichever storage you have on hand. The device reads multiple audio formats, so you don't need to convert files beforehand.
Benefits and Buying Value

This product adds modern features to any car without expensive installation or wiring. It draws minimal power (50-100mA at 12V) and works in a wide temperature range from 0 to 60 degrees Celsius.
Hassle-Free Setup
Simply plug into the DC12-24V socket, pair via Bluetooth, and tune your car radio to the same FM frequency. No tools or professional fitting are required, making it ideal for rental cars or older vehicles.
Compact and Lightweight
Weighing just 30 grams and measuring 73 x 47 x 39 mm, this device fits neatly into the power socket and stays out of the way. Its small footprint means it can remain installed permanently without cluttering the dashboard.
Why Choose This Product
It combines three useful functions—music streaming, handsfree calling, and dual-device charging—into one affordable accessory. The Smart IC USB port adjusts charging speed to suit connected devices, while the FM transmitter avoids the need for auxiliary cables or adapter installations.
