Digital Display USB multifunction tester 3V-30V Mini Current Voltage Charger Capacity Tester USB Doctor power bank meter
Performance parameters
1, input / output voltage: 3V-30V
2, the input / output current: 0A- 3A
3, the test capacity range: 0-99999 mA
4, accuracy: ¡À 1%
5, the test: voltage, current, discharge flow
6, the communication function:
7. Timing: YES
8. The over-current protection: Yes
Second, the use
Power display current and voltage, a single short press the button for about 0.5 seconds to view the capacity and timing screens. When displayed on the screen press capacity around button for two seconds to clear the stored data. When the display screen at the timing of the long press button for two seconds will be flashing numbers, and then press a single button for 0.5 seconds each time the cumulative 0.5 hours per block long press 2 seconds to confirm the save. To not adjusted to the timing of the timer function 0 hours (0 hours is normally open) phone is fully charged to automatically turn off the output. No load 20 seconds automatically shut down output. Current exceeds 3A will automatically shut down when the output voltage is higher than 22V. Close current output window displays OFF. Single short press the button for about 0.5 seconds to activate the output.

Three characteristics
The phone is fully charged to automatically turn off the output. No load 20 seconds automatically shut down output.
It displays the voltage and current data mAH, timing, easy viewing
It can detect mobile power output mAH

Power-down save function
USB and MicroUSB port male double take power, can be detected MicroUSB line quality
Current sampling 50 milliohms, smaller loss
With precision current calibration, higher current accuracy (calibrated okay shipped)

Measuring voltage and current:
USB male plug 5V chargers, mobile phones and other equipment female insert, read current and voltage directly
MicroUSB line quality measurement: female plug mobile phones and other devices, first use the native male plug 5V chargers, remember that voltage, then MicroUSB cable into the bore in mind that the machine MicroUSB charger voltage from 5V, the smaller the gap voltage MicroUSB cable quality is better

Battery capacity test:
Use TP4056 and other linear charging circuit through this capacity to the table completely empty battery is fully charged to full capacity reading on the battery capacity, the use of this method can be measured charge capacity of the phone, the phone can even calculate the charging efficiency
Mobile measuring power output capacity and efficiency:

The first machine connected mobile power, mobile power turn on, long press the button until the volume of data to zero, into the phone and more mobile power charging until no power automatically shut down. Next displayed when you turn the unit capacity is the mobile power output mAH. Note that this mAH than nominal mAH small output mAH * Output voltage 5V / battery mAH * Battery voltage 3.7V = mobile power efficiency
