PD 3.1 Chargers Explained

The 240W USB-C Charging Standard

Everything you need to know about USB Power Delivery 3.1, the Extended Power Range, and why it matters for your next charger purchase.

What Is USB PD 3.1?

USB PD 3.1 (Power Delivery 3.1) is the latest USB power standard, released in 2021 and gaining widespread adoption in 2025-2026. Its headline feature is the Extended Power Range (EPR), which raises the maximum USB-C power delivery from 100W to 240W.

This is achieved through higher voltage support — up to 48V at 5A — compared to PD 3.0's maximum of 20V at 5A (100W). This means USB-C can now power gaming laptops, portable monitors, and even some desktop workstations.

For consumers, PD 3.1 means one charger, one cable, all devices — from your iPhone to your MacBook Pro 16" to future gaming laptops.

PD 3.1 FAQ

What is USB PD 3.1?
USB PD 3.1 is the latest USB charging standard supporting up to 240W through USB-C. It introduces Extended Power Range (EPR) with 28V, 36V, and 48V voltage options.
Do I need a special cable for PD 3.1?
Yes, for EPR (above 100W), you need a USB-C cable rated for 240W with an EPR e-marker chip. Standard 100W cables cannot handle the higher voltages.
Is PD 3.1 backward compatible?
Yes, fully. A PD 3.1 charger works with all PD 3.0, PD 2.0, and standard USB-C devices. Voltage and current are negotiated automatically.
What devices support PD 3.1?
MacBook Pro 16" (140W), select gaming laptops, some high-end power banks, and professional devices. Most phones use PD 3.0 which still works with PD 3.1 chargers.
Is PD 3.1 the same as PPS?
No. PPS allows fine-tuned voltage adjustments within PD 3.0/3.1. PD 3.1 adds EPR for 140-240W. Samsung Super Fast Charging uses PPS; MacBook Pro 16" uses PD 3.1 EPR.
How much does a PD 3.1 charger cost?
PD 3.1 chargers with EPR cost $50-100 for 140W models — about $15-30 more than PD 3.0 equivalents. Good long-term value for power users.
