into fixed profiles.
A pair like 20V⎓3.25A describes a voltage and a current rating. Their product is 65 W for that single profile. Multiple pairs are alternatives, not watts to add together.

Decode your fixed label
Supports A or mA, decimals, spaces, ⎓, and slash, semicolon or line separators. A whole malformed entry is rejected. Variable ranges are excluded.
Volts, amps and that straight-line symbol
V is voltage. A is current; 3,000 mA equals 3 A. ⎓ denotes direct current. For an individual fixed profile, volts × amps gives its listed power ceiling. This arithmetic does not identify the protocol.
9V⎓3A = 27 W for that profile. A separate 20V⎓3.25A profile is 65 W. They are not 92 W together.
What to leave out
- AC input such as 100–240V~ is the wall-side rating. Do not enter it as a USB output.
- PPS or AVS ranges require protocol-specific interpretation. A range such as 3.3–11V is not a fixed 11 V profile.
- Total multi-port watts do not describe a port when several devices are connected. Find the exact port allocation first.
- 28 V, 36 V or 48 V entries need EPR verification. This version marks them outside its ≤20 V comparison.
A label can leave gaps
A printed device rating may show one target without listing every accepted input. We do not infer extra voltages or a minimum operating power. An empty or non-overlapping list leaves compatibility unknown.
The parser is a transcription aid. Review and edit the rows in the matcher, then explicitly confirm them. It cannot read a cable, negotiate with a device, detect counterfeits or check product safety.
