You need to use a car charger converter. The specific instructions are as follows: 1. Car Power Converter: A car power converter (also known as a power inverter or Power-Inverter) is a device that converts DC12V, DC24V, DC36V, or DC48V direct current into AC220V or AC110V alternating current, which is the same as household electricity, for general electrical appliances. It is a convenient car power converter. 2. How to Use a Car Charger: (1) Insert the USB car charger head into the car cigarette lighter, and output DC voltage through the standard USB interface. (2) The electronic design parameters such as voltage and current fully comply with the PDA phone standard and will not cause damage to the device. (3) Connect the USB data cable to power or charge various electronic products such as MP3/MP4, mobile phones, small speakers, Bluetooth devices, and PSP.
Connecting your car's USB is actually very simple. The first thing I do every time I get in the car is to find the data cable. The original cable has the best compatibility, and the length just needs to be sufficient. First, plug one end of the data cable into the car's USB port, which is usually located in the center console or under the dashboard. Some cars even have a dedicated phone slot. After connecting the other end to your phone, a prompt sound or icon will appear on the dashboard. Here's the key point: You must enable USB debugging mode on your phone for stable data transfer! For Android, search for Developer Options in the settings, and for Apple, select "Trust This Device" when enabling Personal Hotspot. Once connected, you can not only charge your phone but also directly play your music playlist or operate navigation apps, with much lower latency than Bluetooth. Be careful not to connect the data cable on bumpy roads, as it can easily damage the port.
I'm used to connecting my phone to the car's infotainment system as soon as I get in the car, and using a USB connection is more reliable. Choose a high-quality Type-C or Lightning cable, preferably with a magnetic design for easy blind operation. The connection steps are straightforward: plug the data cable into the car's USB port, then connect it to your phone. At this point, the car's screen will pop up asking for permissions—remember to select file transfer or media device mode. Apple users need to trust this computer, while Android users should enable OTG functionality. Once done, your phone's battery will charge quickly, and your music playlist will sync directly to the car's system. Using Gaode Navigation, you can project it onto the dashboard, making driving more focused and safer. A reminder to everyone: don’t choose cables that are too long, as they can get tangled around the steering wheel and cause accidents.
Connecting via USB is actually much more practical than Bluetooth. The wired connection is straightforward: locate the car's USB port (usually marked with a small triangle symbol), plug one end of the cable into the car and the other into your phone. A chime sound indicates a successful connection, and the car's infotainment system will automatically load your media library. With my Huawei phone, I always need to manually enable file transfer mode, while iPhones require trust authorization. The biggest advantage is rapid charging—50% in half an hour is no problem. Music playback is uncompressed for better sound quality, and navigation announcements are clearer. On long trips, it's also great for topping up power banks, as car USB ports generally deliver higher power output than standard chargers.
