Overview
- Reports this week note that purple or turquoise inserts are commonly used to indicate USB 3.1 capability, which offers faster transfers than USB 3.0.
- In Huawei’s ecosystem, purple often signals SuperCharge compatibility, while orange marks earlier fast‑charge and green is associated with Qualcomm’s Quick Charge.
- Color labeling is a marketing convention rather than a universal rule, and some manufacturers either ignore colors or apply them differently.
- Actual fast‑charging depends on a compatible device, a certified cable, and a matching charger, otherwise charging reverts to standard speeds.
- The move to USB‑C combines data, video, and power in a reversible connector, prompting more visual cues like colored inserts, but buyers are urged to verify specifications and certifications.
