The USB monitor can display voltage, current, capacitance and power, press the button to switch among seven different display modes
Has two output: Output I is used for both charging and data transfer, Output II is for large current fast charging
Multifunctions: capacitance checking, capacitance clear, over- and under-voltage alarm, over current alarm and short-circuit alarm
The display is clear and plenty bright enough, two color display with RED & BLUE; High accuracy and ultra-low resistance
A great tool for testing phones, tablets, USB ports, power supply and charger outputs, and current demands of USB devices
Input voltage: 3.20--15.0V
Resolution: 0.01V (<10V); 0.1V (>/=10V)
Measuring current: 0.00--3.00A(10A Max, but cannot work in 10A for long time)
Capacitance measurement: 0-99999mA/H
Capacitance accumulation: YES
Power testing: 0.00-9.99-99.9W
Over-voltage alarm: when voltage >/=5.6V, voltage digital point will flash quickly
Lacking-voltage alarm: when voltage </=4.4V, voltage digital point will flash slowly
Over-current alarm: when current >/=3A, current digital point will flash quickly
Short-circuit alarm: current digital point will flash quickly
OUTPUT I (Two Functions)
1. Support QC 2.0 charging (when OUTPUT I uses QC 2.0 charging, please do not insert any devices into the OUTPUT II)
2. Data communication function : mobile phones or other mobile devices for data transfer with a computer, and at the same time can view the voltage and current values.
3. Charging voltage output function: insert the Original Chargers can charge mobile phones or other mobile devices. The charging current is determined by compatibility.
1. Built-in intelligent charging control IC: match the most appropriate and safest current for your devices automatically. (mainly for Non-original Chargers, but also suitable for Original Chargers)
2. Suitable for: most of mobile phones , mobile power , tablet PCs and other USB devices, such as BC1.2, YT/D1591-2009 and non-BC1.2 (including iPad, iPhone and Samsung Galaxy).
3. No data communication function
