- Latest USB Voltage & Current Tester: YOJOCK USB Testers are widely
used in the quality inspection of 3C digital peripheral products, and
are the first choice for digital gamers and electronic enthusiasts.
Real-time detection of the State of Charge of the Appliance, Voltage,
Current, Power, Capacity and other indicators.
-
Wide Applicability: This USB Tester Measuring voltage: 3.7V-32V;
measuring current: 0-5.1A. Supports QC2.0, QC3.0, iPhone
2.4A/2.1A/1A/0.5A, Andriod DCP/AFC, FCP(9V/2A)/SCP(4.5V/5A), 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.
-
Measuring Data is Guaranteed: Power-off storage function that stores
capacity and energy data when the mobile power is turned off, which is
convenient for subsequent viewing and convenient for capacity energy
measurement of mobile power. Note: Other USB power meter that do not
have a power-down storage function cannot test capacity and energy.
-
Varies of Display modes: 6 kinds of display can be switched. 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, 160 degree wide viewing
angle, high brightness and long working life.
-
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.
