UGREEN Bluetooth Car Charger (5.0+PD+QC3.0+USB Flash Drive+TF) (Black)

UGREEN Bluetooth Car Charger (5.0 + PD + QC3.0 + USB Flash Drive + TF) – CD229 (Black)

The UGREEN Bluetooth Car Charger CD229 is a multi-function in-car adapter that combines Bluetooth 5.0 audio streaming, FM transmission, PD and QC3.0 fast charging, hands-free calling, and direct media playback from USB flash drives and TF cards — all through a single cigarette lighter socket. It targets drivers who want to consolidate several separate accessories into one compact unit, particularly those using older vehicles without AUX ports, Android Auto, or CarPlay support. The CD229 works with any car or truck running a 12V or 24V electrical system, making it broadly compatible across vehicle types.

Bluetooth 5.0 with Auto-Memory Pairing

The CD229 uses a Bluetooth 5.0 chip that pairs with smartphones at twice the speed of older Bluetooth versions and maintains a stable connection across a wider range. It remains connected even when the phone moves to the back seat, where earlier-generation transmitters often experienced dropout. Additionally, the auto-memory function stores both the last-paired device and the last-used FM frequency. Consequently, plugging the unit in on subsequent journeys requires no manual re-pairing or frequency re-entry — the adapter resumes exactly where it left off. Backward compatibility extends to Bluetooth versions 2.0, 2.1, 3.0, 4.0, 4.1, and 4.2, so older smartphones work without issue.

FM Transmission for Any Car Stereo

The CD229 transmits audio wirelessly to the vehicle’s existing FM radio system. Setting it up involves tuning both the adapter and the car radio to the same free FM frequency, after which music, navigation instructions, and call audio all play through the car’s speakers without any physical cable. This makes the adapter particularly practical for vehicles that lack a 3.5 mm auxiliary input or Bluetooth connectivity of their own. The turquoise LED display shows the active FM frequency, current track, volume level, and live vehicle battery voltage in sequence, allowing monitoring of all key parameters without using a phone screen.

Dual Fast Charging: PD 20W and QC3.0

The adapter provides a total output of 31.5W across its charging ports. The USB-C port delivers Power Delivery at up to 20W, which charges compatible iPhones and USB-C Android devices at four times the rate of a conventional 5W car charger. The left USB-A port supports Quick Charge 3.0 at up to 18W for Qualcomm-equipped Android handsets. Both ports operate simultaneously, so a driver and passenger can charge their devices at the same time without either port throttling the other. It is worth noting that the right USB-A port — identifiable by the music icon — functions as a media input for USB flash drives and does not support QC3.0; it outputs at 1.5A for basic charging only.

USB Flash Drive and TF Card Media Playback

Drivers who prefer to play music from local storage rather than streaming services can insert a USB flash drive or TF (microSD) card directly into the CD229. Both accept media up to 64GB and support MP3, WMA, FLAC, WAV, and APE audio formats, covering the most common lossless and compressed file types. When multiple sources are active simultaneously, the adapter follows a fixed priority: Bluetooth audio takes precedence, followed by whichever storage device was inserted most recently. A power-memory function also retains the current track position when the vehicle switches off, so the next journey resumes from the same point in the playlist.

Hands-Free Calling with Noise Suppression

A built-in microphone with CVC (Clear Voice Capture) noise suppression handles incoming and outgoing call audio. Incoming calls switch the audio output automatically from music to the call, and a single button on the unit answers, rejects, redials, or ends calls without requiring the driver to touch their phone. The CVC technology reduces road and wind noise picked up by the microphone, improving call clarity for the person on the other end of the line. Voice commands for Siri and Google Assistant also work through the hands-free system, allowing navigation queries, message dictation, and call placement by voice alone.

Use Cases & Applications

Daily City Commuting

Urban commuters who spend significant time in traffic benefit from having navigation audio, music, and charging accessible through a single adapter. The UGREEN Bluetooth car charger CD229 streams Google Maps or Waze directions through the car speakers via FM, so turn instructions are audible without the driver looking at the phone. Simultaneously, the PD port keeps a near-empty iPhone or USB-C Android topped up during stop-start traffic. Incoming calls switch the speaker output automatically and do not interrupt charging.

Long-Distance and Intercity Road Trips

On longer journeys where mobile data may be inconsistent, playing music from a USB flash drive or TF card avoids buffering and reduces data consumption. The CD229 supports up to 64GB of local storage in FLAC or WAV lossless formats, delivering audio quality that Bluetooth streaming compresses. Furthermore, the power-memory function means a multi-day trip can resume from the correct track after each engine start without manual navigation through a playlist.

Older Vehicles Without In-Built Connectivity

Many vehicles manufactured before 2015 lack Bluetooth, AUX inputs, or both. The CD229 addresses this directly by using the FM radio — a feature present in virtually every car stereo — as the audio output channel. No modifications to the vehicle are needed. The adapter plugs into the cigarette lighter socket, and the FM frequency is set within seconds. Consequently, drivers of older cars gain wireless audio streaming and hands-free calling without dashboard replacement or aftermarket installation.

Professional and Business Drivers

Drivers who handle client or business calls while on the road need clear audio quality and safe, single-handed call management. The CVC noise suppression microphone reduces the background noise typical of motorway or highway driving, and the one-button call control means calls can be answered or ended without removing hands from the wheel. Voice command support for Siri and Google Assistant extends this to scheduling, message dictation, and navigation by voice.
