USB 3.0 Power Testing with a Color IPS Display
The USB 3.0 Multimeter Tester is a compact digital USB voltmeter and ammeter designed to inspect chargers, cables, power banks, mobile devices, USB flash drives, and compatible USB 3.0 peripherals. Its 0.96-inch IPS color display presents voltage, current, power, capacity, energy, equivalent impedance, and temperature.
Measure and Diagnose Charging Performance
Measure voltage from 3.7V to 32V and current from 0A to 5.1A, with power measurement up to 120W. The meter provides 0.01V voltage resolution, 0.001A current resolution, and a 0.5Hz refresh rate. Six selectable display modes and a 160-degree viewing angle support quick inspection.
Fast-charge protocol detection identifies QC 2.0, QC 3.0, Apple 2.4A/2.1A/1A/0.5A, Android DCP/AFC, FCP, and SCP charging modes. Comparing voltage under no-load and load conditions can also help evaluate charger and cable performance.
Power-Off Data Storage
Accumulated capacity and energy readings remain available after power is disconnected, making the tester useful for reviewing measurements and checking power-bank capacity.
