This method can also be used to measure the charging capacity of the mobile phone, and even calculate the charging efficiency of the mobile phone\u003cbr\u003eTest Micro USB Cable Quality: \u003cbr\u003eWhen plugging mobile phones and other devices into the female socket, first plug the 5V charger with the male head of the machine, remember the voltage, and then use the MicroUSB cable to insert the 5V charger into the MicroUSB hole of the machine and remember the voltage. The smaller the voltage difference, the better the quality of the MicroUSB cable.\u003cbr\u003eMeasure The Output Capacity and Efficiency of The Mobile Power Supply: \u003cbr\u003eFirst connect the power bank to the machine, turn on the power bank, press and hold the button until the capacity data returns to zero, insert the mobile phone and charge more until the power bank runs out of power and automatically shuts down. The displayed capacity is the mobile power output mAH when the machine is turned on next time. Note that this mAH is much smaller than the nominal mAH, output mAH*output voltage 5V\/battery mAH*battery voltage 3.7V=mobile power efficiency\u003cbr\u003eData Clear: \u003cbr\u003ePress and hold the button until (the number of sets of data) becomes the next set and then release the key, it will automatically jump to the next set of data starting from zero.\u003cbr\u003eData View: \u003cbr\u003eDouble-click the button (within 0.5S) to enter the viewing data viewing mode, the backlight LED will flash, and then display the next set of data again, double-click to exit the data viewing mode, and the backlight LED will be on for a long time.\u003cbr\u003eVoltage Is High or Low: \u003cbr\u003eLCD screen arrows, backlight LED will flash, alarm prompt.
