1. Adapt to car power supply
Voltage matching: Car chargers usually support 12V/24V car power supply (common to cars/trucks) and convert it to 5V/9V/12V and other voltages suitable for mobile phones.
Stable output: Built-in voltage regulator chip to prevent voltage fluctuations when the vehicle is started or turned off from affecting charging.
2. Fast charging capability
Support fast charging protocols: such as QC (Qualcomm Quick Charge), PD (USB Power Delivery), Huawei FCP/SCP, etc. Some car chargers can provide 18W/30W/65W or even higher power for mobile phones.
Multi-port output: Dual ports (USB-A + USB-C) or more interfaces can quickly charge multiple devices at the same time (such as mobile phones + navigation systems).
3. Safety protection design
Overvoltage/overcurrent protection: Prevent damage to the mobile phone when the car circuit is abnormal.
Overheat protection: Automatically reduce speed or power off in high temperature environments.
Short circuit protection: Avoid risks caused by poor contact.
Metal shell heat dissipation: Some high-end car chargers are made of aluminum alloy to improve heat dissipation efficiency.
4. Portability and ease of use
Small and compact: does not take up too much cigarette lighter space, some are designed with foldable plugs or ultra-thin bodies.
Plug and play: no complicated settings are required, just plug in the cigarette lighter to charge.
LED indicator: displays the power-on status (some have voltage detection function).
5. Intelligent compatibility
Automatic device identification: matches the best charging protocol according to the mobile phone model (such as iPhone enables PD fast charging).
Wide voltage input: adapt to different models (12V sedan/24V truck).
