USB Tester Voltmeter Ammeter (TYPE-C) — precise charging and power measurements Key benefits See accurate voltage, current, capacity and ripple readings at a glance on a 2.0-inch high-definition LCD. Data display is clear and easy to read for faster decision making. Detect quick charge protocols and trigger measurements automatically to verify fast-charging performance. Test full connector pinouts and high-current paths with the 5P high-current A and 24P full-pin input/output interfaces for comprehensive charging and cable diagnostics. What it does (functions) Voltmeter and ammeter: real-time voltage and current monitoring for USB Type-C connections. Quick charge detection and trigger: identifies when fast-charge negotiation occurs and captures the relevant data. Capacity measurement: cumulative mAh/Wh tracking to verify battery pack or power bank capacity. Ripple measurement: shows voltage ripple to help assess power quality from adapters and chargers. Full-pin input/output support: 24P full pin interface plus 5P high-current A interface for complete connector testing. Compatibility and interfaces Works with USB Type-C chargers, cables, power banks and USB devices. Equipped with 5P high-current A interface for high-current paths and a 24P full-pin input/output interface to access all connector pins for detailed testing. Display and accuracy 2.0-inch LCD high-definition display presents measurement data clearly. High display-area resolution accuracy ensures readable, reliable measurement values for troubleshooting and verification. Practical applications Verify a phone or tablet charger: confirm that a Type-C charger negotiates quick-charge correctly and delivers expected voltage/current during charging. Test a power bank or battery pack: measure delivered capacity (mAh) and charging behavior to confirm performance against specifications. Diagnose adapter and cable issues: inspect voltage ripple and full-pin continuity to identify noisy or faulty power supplies and connectors. Why you might need it Quickly confirm whether chargers, cables and power banks are performing as claimed. Troubleshoot inconsistent charging, slow charge times, or unstable power supplies by checking voltage, current and ripple. Perform comprehensive connector and pin-level tests with the 5P and 24P interfaces for more detailed diagnostics.
