The useful distinction
Understand the requirement.
A recommended power supply describes capacity to provide, not continuous energy use. [C167A]
The Raspberry Pi 27 W supply documents a 5.1 V / 5 A profile; its other voltage profiles do not imply 5 A at every voltage. [C167B]
Bounded facts, visible unknowns
Specifications and limits
Recommended supply is not measured demand facts and limitations
Scope
Public-reference investigation, not live hardware or independent approval. [C167A][C167B]
Verified device list
Not included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.
Identify the model and intended use. A selection in this atlas is a public reference; confirm the actual equipment and its condition. This tool does not change device settings or certify an installation.

What to check
Confirm the exact model and source scope.
Distinguish recommendation, example and included supply from actual demand.
AI-assisted inspection is not independent engineering review. Source scope and access limitations are disclosed below. Procedural checklists are editorial requirements, not hardware measurements.

Scoped support: The 5.1V, 5A output is 25.5W. Other listed modes are 9V/3A, 12V/2.25A and 15V/1.8A. The 27W product name is not a claim of 27W at 5.1V.
Not established / limitations: Factory cable assembly only. No extension, modified lead, negotiated runtime or universal device-support inference.
