    White Mini LCD Screen USB Tester Description: This product can test USB charging current, voltage, discharge capacity, intelligent devices. It will show the current and voltage at the same time, convenient to check. It can be very easy to find digital devices charging problem. The only button on the tester is used to view and test data switch, the tester can store 10 groups of test data. If there were no battery, it won't lose the data it has tested. It can test current and voltage of phone, mobile power bank etc. With a USB output port and a micro USB input, convenient to test devices With LCD screen, easy to see the current and voltage of the devices Press the small circle button and the data will be zero, then you can test next data Portable design, easy to carry   Specification: Material: Plastic and Electronic Component Color: White Input Voltage: 3V-7V Capacity: 0-19999mAh   Package Included: 1pcs * Portable LCD Dual USB Charger Mobile Power Detector Voltage Current Meter Tester Black Mini LCD Screen USB Tester Description:           No need for professional wiring, easy to use, just plug in the USB port, discharge and charge, you can monitor the working current and voltage of the device, and count the battery capacity. The surface of the new machine screen is covered with a protective film, if you do not need to tear it off   Can be used as a daily simple test tool: 1. It can detect the charging capacity of the battery of the tablet and mobile phone, and judge how much the battery performance drops, and whether it needs to be replaced. 2. It can detect the discharge capacity of the charging treasure and calculate the conversion rate of the charging treasure. 3. It can detect the charging current of your digital device. 4. 5V router and other 5V USB port devices (such as USB lights) operating current, etc.   It comes with a usb input line and a microusb port, which can be input with other lines. One end is connected to the power supply/mobile power supply. Note that the default is to use the usb interface, that is, 5v; the other end is connected to the load, which can be a mobile phone.   Parameter: Input voltage: 3V-15V Voltage resolution: 0.01V Test current: 0.05A-3.50A Current resolution: 0.01A Capacity range: 0-19999mAH Accuracy: plus or minus 1% Line loss: about 0.1 ohm Test content: battery voltage, current, discharge capacity (a total of 10 sets of data) Product weight: 50g Dimensions: 60 * 28.5 * 15mm (without cable), the line length is about 15 cm. Color: white, black, white (+load), black (+load)   Reminder:  1, this baby has been corrected at the factory, can be used immediately after hand! 2. A protective film is attached to the screen, and a smooth screen surface can be seen after being torn off.   Package Included: 1pcs * Tail LCD USB Current Voltmeter Monitor Tester Detects Mobile Phone Charging Mobile Power Capacity Measuring voltage and current: The USB male plugs in the 5V charger, the female socket is plugged into the mobile phone and other devices, and the voltage and current parameters are directly read out. Measure the quality of the MicroUSB cable: Insert the mobile phone and other equipment, first use the male plug of the machine to plug in the 5V charger, remember the voltage, then use the MicroUSB cable to plug in the MicroUSB hole from the 5V charger to remember the voltage, the smaller the voltage gap, the better the quality of the MicroUSB cable. Measuring battery capacity: Use the linear charging circuit such as TP4056 to fully charge the completely dead battery through this capacity meter. The capacity reading is the battery capacity. This method can also measure the charging capacity of the mobile phone and even calculate the charging efficiency of the mobile phone. Measuring mobile power output capacity and efficiency: First connect the unit to the mobile power, turn on the mobile power, long press the button until the capacity data is zero, insert the phone to charge multiple times until the mobile power is turned off automatically. The display capacity is the mAH of the mobile power output the next time the unit is turned on. Note that this mAH is much smaller than the nominal mAH, output mAH* output voltage 5V / battery mAH * battery voltage 3.7V = mobile power efficiency Clear data: Press and hold the button until (the first group of data) becomes the next group and then release the button, automatically jumping to the next set of data starting from zero. Data view: Quickly double-click the button (within 0.5S) to enter the view data view mode, the backlight LED will flash, then display the next set of data, double click to exit the data view mode, and the backlight LED will be on. High or low voltage alarm: The LCD arrow and backlight LED will flash and the alarm will prompt. Press the button LED to light 30S. Power on status: Connect the power through the MicroUSB or the USB cable with the cable. The entire content of the LCD screen displays 1S (detecting whether the LCD screen is intact), then displaying the last data (capacity, and the first group of data), the current voltage, current and voltage are high. Or a low hint. Data calibration function setting: one electronic load meter, one constant current source. The constant current source is adjusted to 8.5V or above and 10V or less (recommended 9V), and the electronic load is set to CC mode (constant current mode). The four currents of 3A, 2A, 1A, and 0.3A are respectively calibrated. Take 3A as an example: 3A calibration: The electronic load is set to constant current mode 3A, the current of the fuel gauge LCD screen will be automatically and slowly calibrated (about 10S). The current of the LCD screen will be changed. After the calibration, the electronic load data will be automatically protected.
