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 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.
Accumulated capacity and energy readings remain available after power is disconnected, making the tester useful for reviewing measurements and checking power-bank capacity.
What measurements can this USB tester display?
It displays voltage, current, power, capacity, energy, equivalent impedance, and temperature across six selectable screen modes.
Can this USB multimeter identify fast-charging protocols?
Yes. It detects QC 2.0/3.0, Apple charging modes, Android DCP/AFC, FCP, and SCP protocols supported by the connected equipment.
Does it save battery-capacity data after disconnection?
Yes. Its power-off storage function retains accumulated capacity and energy readings when USB power is removed.
Can it help compare USB chargers or cables?
Yes. Comparing voltage under no-load and load conditions can help reveal voltage drop and evaluate charging-system performance.
