Once I know it's purpose, I mark the cables with a letter:
- USB A to micro-B only with ground and VBUS wires, limiting power transfer to 0.5 since they can't indicate battery charge: **P**

<img src="picture/a-b-p.webp" title="front" width="250"/>
- USB A to micro-B, with data line shorted internally to indicate 1.5A battery charge (even when not sure the host supports it): **C**
<img src="picture/a-b-c.webp" title="front" width="500"/>
<img src="picture/a-b-c.webp" title="front" width="250"/>
- USB A to micro-B with data wires, but error prone since not shielded (sufficient for low speed): **D**
<img src="picture/a-b-d.webp" title="front" width="500"/>
<img src="picture/a-b-d.webp" title="front" width="250"/>
- USB A to micro-B with shielded data wires (good for high speed): **S**
<img src="picture/a-b-s.webp" title="front" width="500"/>
<img src="picture/a-b-s.webp" title="front" width="250"/>
- USB A to C without data lines but battery charge indication: **C**
<img src="picture/a-c-c.webp" title="front" width="500"/>
<img src="picture/a-c-c.webp" title="front" width="250"/>
- USB A to C with unshielded data lines: **D**
<img src="picture/a-c-d.webp" title="front" width="500"/>
<img src="picture/a-c-d.webp" title="front" width="250"/>
- USB A to C with SuperSpeed data lines, and shielded: **3**
<img src="picture/a-c-3.webp" title="front" width="500"/>
<img src="picture/a-c-3.webp" title="front" width="250"/>
- USB A to C with SuperSpeed data lines, but unshielded: **D**
<img src="picture/a-c-sd.webp" title="front" width="500"/>
<img src="picture/a-c-sd.webp" title="front" width=2500"/>
- USB C to C with shielded data lines: **S**
<img src="picture/c-c-s.webp" title="front" width="500"/>
<img src="picture/c-c-s.webp" title="front" width="250"/>
- USB C to C with electronic marking allowing 5A charging: **C**
<img src="picture/c-c-c.webp" title="front" width="500"/>
<img src="picture/c-c-c.webp" title="front" width="250"/>
- USB C to C with all features: **F**

The tester can detect electronically marked C to C cables.
Often they are present (and required) in cables allowing 5A/100W charging.
