Fixed output or PPS: read the documented option

Keep exact source scope, profile alternatives, numerical bounds and physical observations separate.

The useful distinction

Read the full source model, port case and evidence type before comparing a hypothetical request.

Claim inspection dates: 2026-10-03 · Independent review pending

Guide note · not an individual product specification

The useful distinction

Understand the requirement.

A fixed voltage pair and a programmable range answer different questions. [C173A]

Google’s GW8L7 guide separately describes USB PD fixed outputs and PPS upper values. [C173B]

Bounded facts, visible unknowns

Specifications and limits

Fixed output or PPS: read the documented option facts and limitations
ScopeDocumentary comparison only; no live negotiation or connection approval. [C173A] [C173B]
Verified device listNot included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.

Samsung’s Canadian 45W table assigns different current limits to different PPS bands. A request must be compared with one complete documented option, not a voltage taken from one row and a current from another.

Before you connect

What to check

  1. Identify the exact source SKU and relevant output case.
  2. Compare one complete documented option at a time.
  3. Preserve unknown bounds and unverified observations.

Documentary comparison is not negotiation

The profile worksheet does not communicate with a charger, read a USB message or identify a receiving device. Passing an arithmetic bound cannot establish a real power contract or charging speed.

Google · Manufacturer / product-owner domain · inspected 2026-10-03 · due 2027-01-01

Within inspection window

Scoped support: The guide identifies US model GW8L7 and lists four fixed output pairs. PPS entries give upper voltage/current values, with a 45 W ceiling; no lower PPS voltage is stated in those sections.

Not established / limitations: GW8L7 scope only, not a retailer’s model alias or another regional identifier. PPS lower bounds and actual APDO messages are unrecorded. Upper voltage/current values must not be multiplied into a power claim exceeding the stated cap.
