USB Tester Charging Voltage Output Voltage Current Power Tester for Tablet Feature:1. Charging Performance: Built in intelligent charging recognition IC, which can automatically match high current charging, and can charge 2 different USB devices at the same time.2. Compatibility: Suitable for all original chargers (including for IOS series), charging identification using the charger USB port and without any changes.3. Data Communication: When the input terminal is plugged into a computer and connected to a cell phone or other USB mobile device, data can be transferred with the computer, and the voltage at the time of transfer can be viewed.4. Capacity View: Power on the device without connecting to any USB device, the displayed capacity is the last accumulated capacity, and the accumulated capacity has a power off memory function.5. Alarm Function: The tester has over voltage alarm, under voltage alarm, over current alarm and short circuit alarm, which brings you a safe using experience.Specification:Item Type:DualUSBVoltageCurrentTesterMaterial: ABSProduct Parameters:Display Mode: 0.28in LED, two color (red blue)Product Size: Approx: 69x26x19mm/2.71x1.02x0.74inUSB Extension Cable: 120mmMeasurement Accuracy: 0.1% (3 bits)Measurement Rate: 500mS/ timeWorking Environment:Operating Temperature: -10-+65Working Humidity: 10 - 80% (no condensation)Working Pressure: 80 -106kPaSun Exposure: Not direct exposureProduct Functions:Input Voltage: 3.20-30.0V (decimal point automatic shift)Test Voltage: 10V below resolution: 0.01V, 10V to. Upper resolution: 0.1VTest Current: 0.00-3.00A (maximum 10A, and can not work for a long time) Resolution: 0.01AAutomatic recognition: OUTPUT II built in intelligent charging control IC, and can automatically match your phone, tablet with the right and safe high current charging.QC2.0/QC3.0: OUTPUT I support for Qualcomm QC2.0, QC3.0 charging (note, when QC2.0 and QC3.0 are charged, OUTPUT II cannot be plugged into other devices)Capacity Test: 0-99999mA/H (i.e. 99.999A/H)Capacity Accumulation:In the case of constant charge, the accumulation of N charge capacityCapacity View: Power on the device without connecting to any USB device. The displayed capacity is the last accumulated capacity, and the accumulated capacity has a power off memory function. 2. After the power on capacity is reset, the capacity displayed is the accumulated capacity of N charges or discharges. 3. You can switch to view by pressing the buttonCapacity Reset: 1. After power off, when you power on the device and then charge it, the accumulated capacity is reset in two flashes. 2. Press and hold the button to accumulate capacity, the accumulated capacity will be zeroed with "two flashes".Power Test: 0.00-9.99-99.9W, automatic shift of decimal pointOver Voltage Alarm: When voltage >/=5.6V, voltage decimal point - flashUnder Voltage Alarm: When voltage /=3A, the current decimal point - flashShort Circuit Alarm: Current decimal point- flashButton: One button to switch between 7 different display modes:Only VA - only C - only P - VA+C - VA+P - C+P - VA+C+PLong press the key to clear the accumulated capacityWhen the alarm prompts, you can long press the button to cancel the alarm prompt functionPackage List:1 x USBTesterNote:1.
