USB Power Delivery overview

USB Power Delivery supports negotiated power up to 240 W in compatible systems.

Also called USB PD Power Delivery PD 3.1 240W USB charging

Negotiation across the whole system matters; fit is not power approval.

The useful distinction

Read charger, cable and device specifications independently. This record explains requirements and does not approve chargers, wiring, repairs or barrel substitutions.

C004K

USB-IF’s January 2026 cable guidance separates data performance from 60W/240W power markings. USB 2.0 Type-C cables can use power-only logos without a displayed data rate.

USB-IF compliance-program markings; not independent authentication or video qualification.

S511 · USB-IF

C040B

USB Power Delivery permits power flow independently of the data-host role and a supported system envelope up to 240W. A powered monitor can charge a laptop while receiving its video.

Negotiated power with suitable equipment and cable, not mandatory power from every port.

The useful distinction

Understand the requirement.

USB Power Delivery supports negotiated power up to 240 W in compatible systems. [C040A]

Specifications and limits

USB Power Delivery overview facts and limitations
Specification-level ceilingUp to 240 W in a compatible negotiated system [C040A]
Actual delivered powerNot calculated or guaranteed here [C040A]
Verified device listNot included. Check exact device and accessory documentation.
No electrical replacement approval.

This is a scoped requirements guide, not an interoperability certification. It does not test hardware, calculate an arbitrary display timing, or replace the exact product documentation. A missing capability stays unknown.

Before you connect

What to check

  1. Use the device maker’s supported charging guidance.
  2. Check charger output profiles, cable rating and device input support.
  3. Do not infer charging capability from data speed or a reversible plug.
