Notes:
Before use, please read the following instructions carefully.Because the PD charger has a special PD protocol, it will not work until the output is connected.Please connect your mobile phone and it will work normally!
This product is a dual purpose USB and Type-c product.The USB interface is inserted into the USB charger, and the USB tester screen displays.The TYPE-C is inserted into the PD port, but it does not display.Please connect the TYPE-C output to your phone and it will be screen display!

Key operation instructions
1.Short press the button to switch the screen,
2.Quickly double-click the capacity(mAH) to clear zero ,
3.Quickly three-click the electric quantity( WH) to clear zero,
4.Quickly four-click time to clear zero,
5.Quickly five-click is to change the cumulative data storage group number (NO.X, 10 groups of data),
6.Long press button the capacity and power time to clear all at once,
[external link removed] the (Screen rotation) interface, long press the button to rotate the screen;
8.When the short key is pressed to the over voltage(>35.0V), low voltage(<3.00V) and over current(>8.00A)
setting interface, the value can be adjusted by quickly double-clicking(+ add) or quickly three-clicking(- reduce).9.Restore factory settings: click the button to switch to the off-screen interface, long press
the button to enter the product background, select reset to restore the factory settings!

ATORCH multifunctional interface display and introduction of various parameters
【Regarding testing the charging capacity of the power bank/mobile phone battery】
Let's make an analogy; Our instrument shows that 9V2A is the charging current for the phone.When the charging power remains unchanged, the actual charging voltage of your phone battery is 3.7V, and the charging current reached is 4.86A (for the same charging time, your device has accumulated 4.86A, while our device has accumulated 2A, so our accumulated capacity seems relatively small, but the accumulated Wh power remains unchanged)
At this point, according to another physical formula, the power Wh ÷ 3.75V mobile phone battery voltage=capacity value; The tested capacity is multiplied by 90% efficiency, which is close to the capacity of a mobile phone battery (similar to a power bank battery)
For example, if the test battery is 27Wh, apply the formula:
27Wh (electricity) ÷ 3.75V (battery voltage) × 90% (conversion efficiency)=6.48Ah × 1000=6480mah
The engineer once again has several technical upgrades:
1)This time the green USB male connector is used, and the 1 milliohm low internal resistance sampling resistor is used, and the maximum current of 6.5A can be tested!
2) USB-C male head replacement cost of copper pin contact plug better, tighter current data more reliable.3) increase the screen 180 degrees flip display settings function, to adapt to some chargers using inverted display as a positive display (click to “Screen rotation” interface, and then double-click the key to make it 180 degrees reverse display).4) the optimized PD protocol is suitable for Apple's 87W charger, and both the positive and negative side can transmit the ACC pin of the PD protocol.5) the OTG protocol of Type-C can open the OTG digital function by inserting a random embedded Android switch head in the upper left corner of Android line.6) increase the interface settings such as overvoltage, low voltage, overcurrent, etc., and switch to the corresponding interface at the short button at the front desk, set up by adding double-click or three click setting value.7) challenge limit by metal industry upgrade patch manganin sampling device reduces the resistance to <1mR, access after use almost does not affect the charging speed, the perfect support for HUAWEI 4.5A super fast charging current, like a data line, the more coarse the more shorter the better, faster charging
8) the built-in PD protocol can open the Type-C int
