PORTSCOPE · DECLARED EVIDENCE ONLY
140W on the box is not every port’s limit.
Check the published port allocation for one reviewed charger and laptop profile. This does not measure USB-PD power or diagnose charging problems.
No result yet
Confirm your records and port state, then run the check.
What this result can and cannot say
A published ceiling is not actual negotiated or sustained power. A 240W cable cannot raise the port’s limit. E-marker requirements and thermal reduction still apply. This check cannot establish safety, compatibility, charging under load, battery runtime, or the cause of an observed reading.
Only captured allocation rows are supported. Unsupported combinations stay unknown rather than being extrapolated.
