Mobile Phone USB Tester Capacity Meter Voltmeter Ammeter LCD Display Voltage Current Detector
Doubting for charging cable to be faulty? Test it out with the USB Charger Tester!
Both voltage current and mAH data are displayed for easy viewing. The mobile power output mAH can be detected. It‘s does not affect data transfer and the accuracy is higher, and the current parameters basically do not jump.
USB male head and MicroUSB port dual power, can detect the quality of microUSB cable with Multiple sets of detection data storage, power.The current is sampled at 25 milli-euros with less loss With precision current calibration, higher current accuracy .
- Voltage current measurement

How to use:
- Voltage current measurement->USB male plug in 5V charger, mother plug mobile phone and other devices, directly read out the voltage current parameters.
- Measuring microUSB line quality ->Mother plug mobile phone and other devices, first with the machine male plug 5V charger, remember the voltage, and then use the MicroUSB cable from the 5V charger inserted into the machine MicroUSB hole to remember the voltage, the smaller the voltage gap, the better the quality of the MicroUSB line.
- Measuring the output capacity and efficiency of mobile power supply->First of all, the machine connected to the mobile power supply, turn on the mobile power supply, press and hold the key until the capacity data zero, plug into the mobile phone multiple charges until the mobile power supply no power automatically shut down. The next time you turn on this machine, the display capacity is the mAH of the mobile power output. Note that this mAH is much smaller than the labeled mAH, and the output mAH output voltage 5V/battery mAH x battery voltage 3.7V is mobile power efficiency.
- Data switching ->Click the button to switch to the next set of data, double-click the key to switch to the last set of data.
- Data zeroing ->Press and hold the button for more than 3 seconds to clear the group data.
