USB Type-C source/charger side connection for the KWS-2301C tester; manual states the tester measures charging voltage from 4-30 V and current from 0-12 A.
USB Type-C load/device side connection; passes the charging path through the tester so voltage, current, power, capacity, energy, and current direction can be displayed.
Back-side button; single click changes display page, double-click changes display direction, long press about 3 seconds clears recorded timing, capacity, and power.
