How USB Charging Works
USB (Universal Serial Bus) charging is a widely used method for powering and charging electronic devices. The process involves the transfer of electrical power from a power source to a device using a USB cable. USB charging has become standard for smartphones tablets cameras and various other gadgets.
USB charging involves several key components:
- USB Cable: The cable connects the device to the power source.
- USB Port: The port on the device or power source where the USB cable is plugged in.
- Power Source: This can be a wall adapter computer power bank or any other device providing electrical power.
- Device: The electronic gadget or device that needs charging.
