The useful distinction
Understand the requirement.
Build a conservative source-side reservation scenario without confusing it with measured consumption or an installation guarantee. [C145A]
The exact G5 Bullet page states 4 W consumption; the general Ubiquiti availability page states 5 W. The conflict is unresolved. [C145B]
Bounded facts, visible unknowns

Not included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.
Each selected af endpoint reserves 15,400 mW; each at endpoint reserves 30,000 mW. Counts are integers and the total is calculated in milliwatts. This intentionally conservative reservation does not claim to reproduce a switch's live allocation, classification, negotiation or power management.
Check the source's total documented PoE output, number of available powered ports and per-port limit. A positive total balance does not resolve too many endpoints or a per-port requirement the source cannot document. Optional headroom is your stated scenario input, not a recommended safety margin.
Keep unresolved evidence visible
The exact G5 Bullet page states 4 W while a general Ubiquiti table states 5 W. That conflict remains visible. Neither figure drives this tool's af reservation. A mathematically fitting scenario is still subject to source review, exact hardware/supply checks, actual port state and independent installation assessment.
AI-assisted inspection is not independent engineering review. Source scope and access limitations are disclosed below. Procedural checklists are editorial requirements, not hardware measurements.

The af scenario reserves 15.4 W at the source, while the cited device-side maximum is 12.95 W. The at scenario reserves 30 W at the source, with a cited device-side maximum of 25.5 W. Cable delivery losses are one reason the boundaries differ. Do not subtract a device-only figure from a source budget and label the result certified capacity.
