3. Dual USB Charging – 18W Fast Charge Plus Standard Port
The Oraimo Boulevard 32D features two USB‑A ports to keep your devices powered on the road:
Port 1 (Fast Charge): Delivers up to 18W (5V/3A, 9V/2A, 12V/1.5A), compatible with Qualcomm Quick Charge and other fast‑charging protocols. This port can rapidly charge smartphones (e.g., Samsung Galaxy, Google Pixel, iPhone) and even tablets.
Port 2 (Standard): Provides 5V/0.5A (2.5W), suitable for charging secondary devices like earbuds, smartwatches, or for connecting a USB flash drive for music playback (see section 5).
Both ports are always active when the car is on, so you can charge two devices simultaneously while enjoying your audio.
4. FM Transmitter – Stream Music to Your Car Radio
The core function of the Oraimo Boulevard 32D is its FM transmitter. It broadcasts audio from your phone (via Bluetooth) or from a USB drive / TF card to an FM frequency of your choice (87.5 – 108.0 MHz). Simply tune your car radio to an unused FM frequency (e.g., 88.5 MHz), set the device to the same frequency, and any music or navigation prompts from your phone will play through your car’s speakers. This is an ideal solution for older vehicles without Bluetooth or an AUX input.
The transmitter provides clear, static‑free sound when you choose a frequency not used by local radio stations. The digital LED display shows the current frequency, and you can easily adjust it up or down with the physical buttons.
5. Three Ways to Play Music – Bluetooth, TF Card, USB Flash Drive
The Oraimo Boulevard 32D offers three independent music playback sources:
Bluetooth: Pair your smartphone wirelessly and stream music, podcasts, or audiobooks. The device supports standard Bluetooth profiles and will remember your phone for automatic reconnection.
TF Card (microSD): Insert a microSD card (up to 32GB) loaded with MP3 or WMA files into the TF card slot. The device will automatically play music from the card.
USB Flash Drive: Connect a USB flash drive (up to 32GB) with MP3/WMA files to the standard USB port (Port 2). The device will read and play the files directly.
You can switch between sources using the physical buttons on the device. This makes the Boulevard 32D incredibly versatile – you can leave a USB drive loaded with your favourite road trip playlist permanently connected, or stream new music from your phone.
6. Hands‑Free Calling with Built‑in Microphone
The Oraimo Boulevard 32D includes a built‑in microphone and a dedicated answer / reject button, allowing you to take hands‑free calls while driving. When a call comes in, the music automatically pauses, and you can press the button to answer. The microphone is positioned to capture your voice clearly, and the call audio is played through your car’s speakers via the selected FM frequency. This keeps your hands on the wheel and your focus on the road, in compliance with hands‑free laws.
The device also supports voice assistant activation (depending on your phone) – long‑press the button to call up Google Assistant or Siri.
7. Digital LED Display – Real‑Time Car Battery Voltage Monitoring
A useful safety feature of the Oraimo Boulevard 32D is its digital LED display that shows not only the current FM frequency but also the real‑time voltage of your car battery. When you first plug in the device, it will display the vehicle’s battery voltage (e.g., 12.4V). This allows you to monitor the health of your battery and alternator. A healthy battery should read around 12.5V with the engine off and 13.5‑14.5V with the engine running. Significant deviations can alert you to potential electrical problems before they leave you stranded.
The display is bright enough to read in daylight and dimmed for night driving.
8. Easy to Use – Physical Controls and Wide FM Range
The Oraimo Boulevard 32D is designed for intuitive operation while driving. Physical buttons let you:
Adjust FM frequency up/down.
Switch between playback sources (Bluetooth, TF card, USB).
Play/Pause music.
Answer or reject calls.
Adjust volume (though your car’s volume knob is the primary control).
The wide FM range (87.5‑108.0 MHz) covers all standard frequencies, so you can almost always find an unused channel for clean audio transmission.
9. What’s in the Box
When you purchase the Oraimo Boulevard 32D, you will typically receive:
Note: USB charging cables and a microSD card are not included. A TF card or USB drive must be purchased separately if you wish to use those playback methods.
