USB QC 2.0 3.0 LCD Charger power bank Capacity Tester USB Testing Doctor Power

USB QC 2.0 3.0 LCD Charger power bank Capacity Tester USB Testing Doctor Power Meter Ammeter Voltmeter Current Voltage Timing Ship to worldwide via post air mail with tracking number. Specifications:1. Input Voltage: 4V - 30V2.Input current : 0 - 3.5A3.Cumulative capacity range: 0-99999 mah precision: 0.001 Ah4.Charge accumulation scope: 0-999999 MWH precision: 0.001 Wh5.Power range: 0-90W precision: 0.001W6.Timing the maximum range: 0-24hours 59 minute 59 seconds precision: 1 second7.Parameters that you can test: Voltage of battery. Current of battery, discharge capacity of battery,Quantity of electric charge,power of battery,timing.There are 3A, 2A, 1A and 0.3A models for current adjusting.Here is a example for 3A:When you set electronic load at 3A model, the current will be adjusted step by step.It will cost you about 10 seconds and you can see the result changing procedure in the LCD screen.When you see the 3A result shown in LCD screen, the adjustment process is finished. You can shutoff the electronic load and the parameters will be saved automatically.Then the next sets of parameters will be started and they will start from zero.11. Over voltage or under voltage : Over voltage or under voltage, LCD screen displays a warning symbol and issue rapid beep beep sound.Application examplesBecause mobile phones and digital devices at low battery or full charge, the current and voltage is not a stable value,the application example of the dischargedevice is a USB 1A or 2A discharge resistor.Note: This data is mobile power discharge capacity, the battery capacity is not, according to our experience, the discharge capacity is about 1.9 times the battery capacity.The former Test Reference Manual Tester discharge capacity value is cleared,and the mobile power is fully charged.
