Car Charger FM Transmitter

The BONAEVER unit combines a 3.1 A car charger with an FM transmitter and Bluetooth 5.0 hands-free kit. It plugs into a 12 V to 24 V vehicle socket and adds three integrated cables for iPhone, Android and USB Type C devices. Drivers who want a single accessory for charging, music streaming and calls will find it fits the role.

Thermals Noise Power Draw

Rated input voltage spans 12 V to 24 V with a limit range of 8 V to 32 V, delivering a total USB output of 3.1 A. Bluetooth transmission reaches 10 m to 15 m and the FM section covers 87.5 MHz to 108.0 MHz with a 68 dB signal-to-noise ratio. The device operates silently and draws minimal power while charging three devices and streaming audio.

Build Fit And Freedoms

The transmitter occupies one 12 V socket and supplies three fixed cables, removing the need to carry separate charging leads. It supports U disc and TF card playback from 1 GB to 32 GB in MP3, WMA, FLAC and APE formats. Buyers who need more than three simultaneous charge ports or a dedicated high-power laptop supply will need additional equipment.

Questions about this item

How do I install the BONAEVER 3.1A Car Charger FM Transmitter, and what step is often missed?

Plug the unit into the 12 V ~ 24 V vehicle power socket, tune the car radio to an unused frequency between 87.5 and 108.0 MHz, then set the transmitter to the exact same frequency — skipping the frequency match is the step most people miss.

What maintenance or replacement will the BONAEVER 3.1A Car Charger need over time?

The device has no user-serviceable parts; keep the USB ports and the U‑disc/TF card slots free of dust, and replace the unit only if the Bluetooth 5.0 link or FM output fails.

What limit appears first during extended use of the BONAEVER 3.1A Car Charger?

The combined USB output is capped at 3.1 A, so charging three devices simultaneously will hit that current limit before the 10‑15 m Bluetooth range or the 68 dB signal‑to‑noise ratio become factors.
