Does Usb Port Drain Car Battery

It is a common misconception that USB ports can drain a car’s battery. While it is true that a USB port can use power even when nothing is plugged into it the amount of power it draws is very small and is not enough to cause any significant drain on a car battery.

The main way that a USB port can drain a car battery is if it is left plugged into a device that is turned on but not in use. For example if you leave your phone charger plugged into the USB port but your phone is not turned on it will continue to draw power from the battery. over time this can slowly drain the battery.

To avoid this make sure to unplug any devices from the USB port when they are not in use. If you are not using the USB port it is best to disconnect it entirely from the battery to avoid any potential power drain.
