Ugreen UG-80910 Bluetooth Car Charger (5.0+PD+QC3.0+USB Flash Drive+TF)
The UGREEN UG-80910 (CD229) is a compact, multi-function car adapter that combines Bluetooth 5.0 audio streaming, FM transmission, fast charging, and media playback into a single cigarette lighter accessory. Rather than cluttering your dashboard with separate devices, this adapter consolidates charging, hands-free calling, and in-car entertainment into one unit that weighs just 50 grams.
Designed for both 12V and 24V vehicle electrical systems, the UGREEN UG-80910 fits standard cigarette lighter sockets. It draws a maximum input of 3.6A and distributes power across three USB ports with a combined output of up to 31.5W. Additionally, a built-in LED display shows real-time battery voltage, FM frequency, track information, and volume level — providing continuous visibility into your vehicle’s electrical status.
Bluetooth 5.0 Wireless Connectivity
At its core, the UGREEN UG-80910 operates on Bluetooth 5.0 technology with backward compatibility spanning versions 4.2, 4.1, 4.0, 3.0, 2.1, 2.0, and 1.2. This ensures broad device support across smartphones, tablets, and other Bluetooth-enabled sources. The effective transmission range extends up to 5 metres, which comfortably covers most vehicle interiors.
The Bluetooth module on the UG-80910 delivers data transfer speeds of up to 3 Mb/s. As a result, audio streaming remains stable without the intermittent disconnections common in older Bluetooth versions. Furthermore, the adapter features automatic reconnection — it pairs with the last connected device upon powering on, eliminating the need for manual re-pairing each time you start your vehicle.
FM Transmitter and Audio Playback
The UGREEN UG-80910 includes an integrated FM transmitter that operates across the 87.5–108 MHz frequency range in 100 KHz steps. Once tuned to a vacant FM frequency, it broadcasts audio through your vehicle’s existing stereo system. This makes it compatible with virtually any car that has an FM radio receiver.
Beyond Bluetooth streaming, the UG-80910 supports three distinct audio playback modes. You can play music files from a USB flash drive inserted into the dedicated USB-A2 port, or from a TF (microSD) card via the built-in card slot. Both storage options support capacities up to 128 GB. Supported audio formats include MP3, WMA, WAV, and FLAC, with bit rates ranging from 64 to 320 kbps. Consequently, the adapter handles both compressed and lossless audio files without issue.
The playback priority system on the UGREEN UG-80910 operates as follows: Bluetooth audio takes precedence first. If no Bluetooth source is connected, the adapter defaults to the last inserted USB drive or TF card. This hierarchy ensures a predictable and seamless listening experience.
PD and QC3.0 Fast Charging System
The UGREEN UG-80910 features a three-port charging layout. The USB-C port supports Power Delivery 3.0 with output levels of 5V/3A, 9V/2.22A, and 12V/1.67A — delivering up to approximately 20W of charging power. Meanwhile, the USB-A1 port supports QC3.0, FCP, AFC, and BC1.2 protocols with outputs of 5V/3A, 9V/2A, and 12V/1.5A — providing up to approximately 18W.
The third USB-A2 port is dedicated primarily to USB flash drive reading and low-power accessories. It outputs 5V/1.5A and can power devices such as dash cameras or DVRs. When the USB-C and USB-A1 ports are used simultaneously, the combined output caps at 5V/4.8A. Overall, the UG-80910 delivers a maximum total output of 31.5W across all ports.
Hands-Free Calling and Voice Control
The built-in microphone on the UGREEN UG-80910 incorporates CVC (Clear Voice Capture) noise suppression technology. This filters ambient road and engine noise during calls, resulting in clearer voice transmission for both the driver and the person on the other end of the line.
Call management is handled through a multi-function button (MFB) integrated into the rotary knob. A single press answers or ends a call. A press-and-hold action rejects an incoming call. A double press redials the last number. In addition, the UG-80910 supports voice assistant activation, allowing you to trigger Siri or Google Assistant for voice-controlled navigation and calling without taking your hands off the wheel.
Safety Protections and Build Quality
The UGREEN UG-80910 is constructed with an aluminium alloy housing combined with PC and ABS plastics. The outer casing uses fireproof-rated PC material. Internally, the adapter includes four layers of circuit protection: over-voltage, over-current, over-temperature, and short-circuit safeguards.
The real-time voltage monitoring feature displays your car battery’s voltage on the LED screen upon startup. Moreover, the UG-80910 triggers visual alerts on the display when it detects abnormally high or low voltage readings. This early warning system helps drivers identify potential battery issues before they become roadside problems.
