Fast Charge Deception Function:

1>.Support intelligent fast charge deception function to solve the problem of insufficient power supply of USB input port.
2>.Support mainstream fast charging protocol:QC2.0, QC3.0, AFC, FCP, SCP.
3>.User can choose not to deception or automatically choose the deception mode.
4>.Keep press button TRIG for 2 second enter into fast charging protocol select interface.Screen will display fast charging protocol.
5>.Short press button TRIG to select fast charging protocol.
6>.Short press button ON/OFF or SELECT to trigger fast charging protocol.It will display OK and FC indicator turn ON if the triggering is successful.Otherwise display Err and FC indicator turn OFF.
7>.Keep press button TRIG for 2 second again to save and exit set mode.Module will remember this select.
8>.User can select the AUTO mode and the module automatically selects the deception protocol if user don't know which protocol the charger supported.
9>.User can choose the OFF mode if user no need fast charge deception function.

Button/Potentiometer/LED introduction:

1>.Long press means need keep press for more than 3second.
2>.ON/OFF Button:Short press is used to turn ON or OFF output voltage at display mode or trigger charge deception function at fast charge protocol selection mode.Long press is used to set default ON or OFF for next re-power at display mode.
3>.SW Button:Short press to switch display output voltage and output current or trigger charge deception function at fast charge protocol selection mode.Long press is used to switch display output current,output power and capacity statistics.
4>.TRIG Button:Short press to select fast charging protocol.Long press to enter or exit the fast charge protocol selection interface.
5>.CV Potentiometer:Adjust output voltage.Increase the output voltage when rotating clockwise.Please rotate the CV potentiometer 10 turns in counterclockwise if the output voltage cannot be adjusted.
6>.CC Potentiometer:Adjust output current.Increase the output current when rotating clockwise.Note:It is not keeping a fixed output current.When the load current reaches the set current value, the module starts to fix output this current value.Short circuit output terminal when adjust output current.
7>.ON LED:Green Output indicator.It will turn ON when there is a output at output terminal.Otherwise it is OFF.
8>.CC LED:Red Constant current output indicator.It enters the constant current state when the load current reaches the set current and CC constant current indicator turns ON.
9>.FC LED:Blue Fast charge deceiving indicator.Fast charge protocol after the successful deception.
10>.Input terminal:There are four input methods:
10.1>.Method 1:Standard Type A USB Male .It just can input DC 5V.
10.2>.Method 2:Micro USB Female.It just can input DC 5V.
10.3>.Method 3:Type-C USB Female.It just can input DC 5V.
10.4>.Method 4:Pads input DC 4.0V-13.0V.
10.5>.It can only choose one input method.
11>.Output terminal:KF-301-2P 5.08mm blue terminal. It can output DC 1.0V-30.0V.
