How Do Usb-c Connectors Carry 100W At 20V Without Melting?
Introduction
USB-C connectors have revolutionized the way we charge and transfer data between devices. With the ability to carry up to 100W of power at 20V, these tiny connectors have become an essential component in modern technology. However, the question remains: how do USB-C connectors manage to carry such high amounts of power without melting or causing damage to the device?
Understanding the Basics of Power Transfer
To answer this question, we need to understand the basics of power transfer. Power is calculated using the formula P = VA, where P is the power in watts, V is the voltage in volts, and A is the current in amperes. In the case of USB-C connectors, the voltage is set at 20V, which means that the current required to achieve 100W of power is 5A.
The Role of Copper and Wire Gauge
At first glance, it may seem impossible for tiny wires to carry 5A of current without melting. However, the key to understanding this lies in the properties of copper and the concept of wire gauge. Copper is an excellent conductor of electricity, with a high electrical conductivity that allows it to efficiently transfer power. The wire gauge, which refers to the thickness of the wire, also plays a crucial role in determining the amount of current that can be carried.
The Science Behind USB-C Connectors
USB-C connectors use a combination of advanced materials and design techniques to ensure that they can carry high amounts of power without melting. Some of the key factors that contribute to their ability to do so include:
- High-quality copper: USB-C connectors use high-quality copper that is designed to efficiently transfer power.

- Advanced insulation: The insulation used in USB-C connectors is designed to prevent overheating and ensure that the connectors can carry high amounts of power without melting.
- Cooling systems: Some USB-C connectors use cooling systems, such as heat sinks or thermal interfaces, to prevent overheating and ensure that the connectors can carry high amounts of power without melting.
The Role of USB-C's Power Delivery (PD) System
The Power Delivery (PD) system is a key component of USB-C connectors that allows them to carry high amounts of power. The PD system uses a combination of advanced materials and design techniques to ensure that the connectors can efficiently transfer power. Some of the key features of the PD system include:
- High-speed data transfer: The PD system allows for high-speed data transfer, which enables devices to communicate with each other quickly and efficiently.
