Guide note · not an individual product specification
The useful distinction
Understand the requirement.
Do not turn a charger’s rating into a battery-speed promise. [C164A]
Published tests include device and environmental conditions. This worksheet neither measures battery state nor simulates charging curves. A target within an upper bound is not a fast-charge approval. [C164B]
Bounded facts, visible unknowns
Specifications and limits
Fast charging needs the exact model and cable path facts and limitations
Workflow boundary
One documented source, direct outputs, anonymous target assumptions. [C164A][C164B]
Verified device list
Not included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.
The inspected Apple store and support pages use different levels of specificity for the 16-inch cable path. The atlas retains the narrower support condition rather than merging them into a broad compatibility claim.
Before you connect
What to check
Identify the source model and each connected port.
Keep wattage and fixed-voltage requests separate.
Keep unknown cable and occupancy evidence visible.
Published tests include device and environmental conditions. This worksheet neither measures battery state nor simulates charging curves. A target within an upper bound is not a fast-charge approval.
Keep charging separate from displays
A dock’s display result does not certify its charging path. Use display documentation for video questions and a separate power investigation for charging. Multi-hop dock power is outside the new direct-source worksheet.
AI-assisted inspection is not independent engineering review. Source scope and access limitations are disclosed below. Procedural checklists are editorial requirements, not hardware measurements.
