Fast charging identification mode: PD2.0, PD3.0, PPS, QC2.0, QC3.0, QC4, , , PE, DASH VOOC, SuperVOOC, etc. (Note: no Bluetooth function) Super compatibility ultra precision data detection: 0.0001 low resolution, real-time detection of changes in voltage, current and power during charging. Calculation of battery capacity for 10 groups of energy records: 10 groups of charging and discharging energy data records are supported. Built in battery capacity calculation formula. The battery capacity can be quickly according to the recorded data. Four function display: 1. Check the voltage and current curves of the charging changes in real time, and immediately find abnormal charging; 2. Offline recording supports up to 9 hours of offline voltage and current recording, which is displayed during charging; 3. D+D1 voltage can show the change of charging protocol and grasp it in time; 4. High speed power supply ripple measurement can display charger ripple measurement. LCD display: 2.0 inch LCD high-definition display, with clear measurement data. Compatible with all interfaces, equipped with 5P high current USB-A, 24P full pin Type-C input/output interface, charging detection speed is .
