P170 / Charging and power / Guide

Check cable current, not just cable watts

Use explicit voltage and current evidence rather than deriving either from wattage alone.

The useful distinction

Identify the exact model and evidence category before comparing numbers.

Guide note · not an individual product specification

The useful distinction

Understand the requirement.

The same power headline can hide different current or data-rate limits. [C170A]

Eaton’s U420-003-G2-5A and U040-003-C-5A both list 20 V / 5 A / 100 W, while listing different data-rate ceilings. [C170B]

Bounded facts, visible unknowns

Specifications and limits

Check cable current, not just cable watts facts and limitations
ScopePublic-reference investigation, not live hardware or independent approval. [C170A] [C170B]
Verified device listNot included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.

Two cables can share a 100 W rating and document very different data-rate ceilings. Neither a power limit nor a data headline automatically proves a video mode or a live negotiated connection.

Before you connect

What to check

  1. Confirm the exact model and source scope.
  2. Distinguish recommendation, example and included supply from actual demand.
  3. Leave missing input or cable evidence unknown.
