USB Tester Multimeter with QC 3.0 Power Meter and IPS Display 4-30V 0-6.5A

Upgraded USB Tester: Real-time Detection of Electronics' Performance

Key Features - Real-time Detection: YOJOCK Upgraded USB Testers accurately monitor the State of Charge, Voltage, Current, Power, and Capacity of your device in real-time. - Widely Used and Loved: Reliable in quality inspection of 3C digital peripheral products. Perfect for digital gamers and electronic enthusiasts.

Wide Applicability - Voltage Range: Measures Voltage from 4V to 30V. - Current Range: Detects Current up to 6.5A. - Charge Protocol Support: Identifies supported protocols including QC2.0, QC3.0, iPhone 2.4A/2.1A/1A/0.5A, Android DCP/AFC, FCP (9V/2A)/SCP (4.5V/5A), and Super VOOC fast charge. - High Current Testing: Suitable for testing USB3.0 interface mobile hard disks and USB flash drives.

Data Storage and Security - Power-off Storage: Safely stores capacity and power data even when the device is off, ensuring subsequent viewing for accurate measurements. - Guaranteed Data Integrity: Maintenance of critical data during and after testing.

IPS LCD Display - High-Definition Color: 0.96-inch IPS display provides clear visibility of essential indicators such as State of Charge, Voltage, Current, Capacity, Energy, Power, Equivalent Impedance, and Temperature. - 4-bit Accuracy: Ensures precise and reliable measurement results.

Assessing Charger Quality - Load Comparison: Connect the same load to compare no-load and loaded conditions. The larger the voltage drop indicates a lower charger capacity and poorer quality. - Load-Specific Analysis: If the voltage drop is not significant or the voltage rises, it suggests better load capacity and charger quality.
