The term "Lightning bolt USB" most commonly refers not to a specific type of USB cable or port technology itself, but rather to the lightning bolt symbol (⚡) that is often found adjacent to a USB-A or USB-C port. This symbol serves as a visual indicator, signaling a particular capability of that specific port.
Understanding the Symbol
When you see a traditional lightning bolt symbol next to a USB connector on a computer, charger, power strip, or other device, it has a clear meaning related to power delivery.
According to the provided information:
- The presence of a traditional lightning bolt symbol adjacent to a USB-A or USB-C connector indicates fast-charging capability.
- This signifies that the port provides rapid charging functionality for mobile devices.
Essentially, the lightning bolt symbol points out the port designed for quick power top-ups for your gadgets.
What the Symbol Means
The lightning bolt symbol next to a USB port explicitly tells you that the port is configured to deliver higher power than a standard USB port, enabling connected devices to charge much faster.
Key aspects indicated by this symbol include:
- Fast Charging: The primary meaning is that the port supports a fast charging standard.
