  3. Product Highlights
    • Wide applicability: this usb power meter measuring voltage: 4v-30v; measuring current: 0-6.5a. supports qc2.0, qc3.0, iphone 2.4a/2.1a/1a/0.5a, android dcp/afc, fcp(9v/2a)/scp(4.5v/5a), super vooc fast charge protocol identification, let you know the charging status of the phone. support for high current testing, support usb3.0 interface mobile hard disk and u disk test.
    • Ips lcd display: uses a 0.96-inch ips high-definition color lcd display to display the state of charge of the appliance, voltage, current, capacity, energy, power, equivalent impedance, temperature and other indicators at a glance. 4-bit accuracy for more accurate measurements.
    • Upgraded usb tester: real-time detection of the state of charge of the appliance, voltage, current, power, capacity and other indicators. yojock testers are widely used in the quality inspection of 3c digital peripheral products, and are the first choice for digital gamers and electronic enthusiasts.
    • Power-off storage, measuring data is guaranteed: this usb tester has a power-off storage function, which can store capacity and power data when the mobile power supply is powered off, which is convenient for subsequent viewing and facilitates the measurement of the capacity and power of the mobile power supply.
    • Measure the quality of the charger: connect the same load, compare the no-load and load. the larger the voltage drop, the worse the charger capacity, the worse the quality. the voltage drop is not obvious or the voltage rises, the better the load capacity of this charger, the better the quality.
