USB-C 240W Fast Charging: Everything You Need to Know

USB-C 240W fast charging technology marks a significant milestone in this evolution

Advancements in charging technology are transforming how we power our electronic devices.

USB-C 240W fast charging technology marks a significant milestone in this evolution, promising to reshape daily routines and work methods. This article delves into the developmental trajectory, core technological advantages, and diverse applications of this cutting-edge power delivery system.

Evolution of USB Power Delivery Standards

The progression of USB Power Delivery (PD) standards highlights rapid advancements in charging technology:

2015: The USB Implementers Forum (USB-IF) introduced USB PD 3.0, setting the foundation for efficient power delivery.

February 2017: USB PD 3.0 was enhanced with Programmable Power Supply (PPS) functionality, improving charging adaptability.

May 2021: USB PD 3.1 specification was released, introducing 240W charging capabilities.

October 2021: The USB Type-C 2.1 standard was ratified, detailing the technical specifications for 240W fast charging.

Innovations Enabling 240W Fast Charging

Advanced Standards

The USB Type-C 2.1 revision supports up to 48V and 5A power outputs, enabling 240W ultra-high-power charging. This standard provides the framework for powering high-consumption devices like laptops and gaming consoles.

Extended Power Range (EPR)

The Extended Power Range (EPR) protocol, crucial for 240W fast charging, introduces three fixed voltage levels (28V, 36V, and 48V) and supports Adjustable Voltage Supply (AVS). This enhancement allows for more granular and efficient power distribution. The EPR adjustable voltage supply ranges are:

PDP Minimum voltage (V) Maximum voltage (V)

100...140W 15 28

>140...180W 15 36

>180...240W 15 48

Note: Available current is calculated as PDP/Maximum Voltage, rounded down to the nearest 50mA.
