USB Volatage/Amps Power Meter, Digital Tester Multimeter Test Speed of Charger, Cables, Computer, Power Bank
Description: Input voltage: 3V-7V (can be within 12V) 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 ohms Test content:
Battery voltage, current, discharge capacity (a total of 10 sets of data)
Voltage and current measurement: Plug the USB male into a 5V charger, and plug
the female into a mobile phone or other devices to directly read the voltage
and current parameters. Test the output capacity and efficiency of the mobile
power supply: First, connect the device to the mobile power supply, turn on
the mobile power supply, press and hold the button until the capacity data
returns to zero, insert the phone multiple times to charge until the mobile
power supply runs out and automatically shuts down. The next time the machine
is turned on, the displayed capacity is the mAH output of the mobile power
supply. Note that this mAH is much smaller than the nominal mAH, with output
mAH  output voltage 5V/battery mAH  battery voltage 3.7V=mobile power
efficiency. Data switching: Click the button to switch to the next set of
data, and double-click the button to switch to the previous set of data.
Package included: 1xUSB USB Power Current Voltage Tester
