Practical guide / P167
A recommended power supply describes capacity to provide, not continuous energy use.
Practical guide / P168
Separate a listed fast-charge arrangement from an assumed input requirement.
Practical guide / P169
Package contents provide useful context but do not establish minimum input power.
Practical guide / P170
The same power headline can hide different current or data-rate limits.
Practical guide / P171
A general support page and a model specification can use different thresholds.
Practical guide / P172
Create a source-scoped investigation without manufacturing a compatibility verdict.
