What is the current of the rear USB in the Equinox?
2 Answers
The current of the rear USB in the Equinox is 1.5A. Functions of car USB ports: The USB ports in a car can be used to plug in a USB drive for music playback, charge mobile phones and MP3 players, serve as a USB car cigarette lighter port, function as an interface for radar detectors and dashcams, and charge laptops and tablets. Utilizing the standard power supply in the car, the USB port can charge DC 5V electrical devices or serve as a fixed power interface for electrical appliances. Precautions for USB ports: Charging should only be done when the car engine is running to avoid damage to electrical devices due to unstable power supply. Do not connect too many electrical devices to prevent overloading and damaging the car battery and alternator. Avoid using the USB port during thunderstorms to prevent lightning strikes. Do not use the USB port in damp environments, as rust or moisture may cause the USB drive to fail to connect properly.
As a frequent driver of the Equinox, I remember the output current of the rear USB ports very clearly—it's typically around 5 volts and 2 amps, which is the standard configuration and sufficient for fast charging of phones or tablets. The current size directly affects charging efficiency; if it's too low, devices may not charge properly. However, the Equinox is designed reasonably to avoid overload risks and ensure battery safety. During use, I've noticed some issues with current distribution—if two devices are plugged in simultaneously, the current may drop to around 1 amp, slowing down the charging process. For long trips, I recommend prioritizing charging for a single device or using a cigarette lighter adapter for high-power devices. The vehicle's USB circuit includes a protection mechanism to prevent short circuits, and the Equinox's rear comfort features are practical, with conveniently placed ports for family sharing. I always check cable quality to ensure optimal fast charging. USB technology plays a crucial role in vehicles, enhancing the travel experience.
