USB-C Charger, Cable & Device Power Bottleneck Planner

Compare exact charger-port, cable and device power limits, add a load reserve, name the weakest declared link and keep protocol compatibility as a separate evidence gate.

Which part of this USB-C charging path limits the plan?

The declared path ceiling is the lowest of the exact charger-port, cable and device ratings. It must exceed the required load plus reserve, but compatible PDO, PPS or EPR evidence and a physical measurement still control actual charging.

Method

Required planning power equals the entered load multiplied by the reserve. Path cap is the minimum of three first-party ratings; scenarios test a 100W cable and a lower-load case without inventing negotiation profiles.

Important limitation

Headline watts cannot prove a compatible voltage/current PDO, proprietary fast charging, thermal behavior, battery charge curve, cable condition or actual delivered power. Verify manuals and measure the exact path.
