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 calculated according to the recorded data. Four function curve display: 1. Check the voltage and current curves of the charging curve changes in real time, and immediately find abnormal charging; 2. Offline curve recording supports up to 9 hours of offline voltage and current curve recording, which is displayed during charging; 3. D+D1 voltage curve can show the change of charging protocol and grasp it in time; 4. High speed power supply ripple measurement curve 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 faster.
