It supports all commercially available fast-charging protocols and both A-to-C and C-to-C cable configurations.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this USB power meter support fast charging detection?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The meter supports real-time fast-charging detection across all major protocols. It displays the actual voltage and current being delivered during a fast-charging session, allowing you to verify whether your charger and cable are delivering the expected performance.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I reset the data log on the power meter?\u003c\/h4\u003e\n\u003cp\u003eA: Simply double-tap the touch button on the device to reset the information log, including accumulated mAh, mWh, and timer data. This is useful when starting a new charging session or testing a different device.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between mAh and mWh readings on this meter?\u003c\/h4\u003e\n\u003cp\u003eA: The mAh reading reflects the capacity measured at the charging terminal, while mWh reflects the total energy transferred. For fast-charging at higher voltages, mWh provides a more accurate picture of total energy delivered.
