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: ±1%
5, the test: voltage, current, discharge flow
6, the communication function:
7. Timing: YES
8. Over-current protection: Yes
Second, the usage
Power display current and voltage, a short press of the button about 0.5 seconds to display the capacity and timing screens. When displayed on the screen, press capacity around button for two seconds to view the saved data. When the screen on the timing of the long press button two seconds flash numbers, and 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. Exceeds 3A will shut down automatically when the output voltage is higher than 22V. Close current output display windows OFF. Single short press of the button about 0.5 seconds to activate the output.
Three features

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 mAH
Power down save function
USB and MicroUSB port male double take power, can be detected MicroUSB line quality
Current sampling 50 milli, smaller loss
With precision current calibration, higher current accuracy (calibrated okay sent)
Measuring voltage and current:
USB 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 of 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 capacity and efficiency:
The first machine connected mobile power, mobile power turn on, long press the button until the volume of data to zero, in the phone and more mobile power charging until no power automatically shut down. Next displayed when you enter the unit capacity is the mobile power mAH. Note that this mAH than nominal mAH small output mAH * output voltage 5V / battery mAH * Battery voltage 3.7V = cell power efficiency
