Introduction

1.  Part description: 1pc 7-segments digital LED; 2pcs tact switch(on/down, off/up); 1pc 3.6mm DC block, charge and discharge are for this same port.

2.  7.2V lithium protection function: 8.5V over-charge protection; 3A over-current, short-current etc basic protection function.

3.  Intelligent 5-speed control: Constant power output.

 (1).Power on: Connect to the load, press the tact switch for a while, LED display the number '1', it means successful start, output voltage 5V; decimal point twinkling( that states: output voltage regulation, 8seconds after decimal point off, digital LED will display current battery).

(2)Adjust the output voltage decreases operation: press tact switch 'DOWN', LED displayed value increase, output voltage decrease, when minimum voltage output, LED displayed the number '5'.

(3) Adjust the output voltage increases operation: press tact switch 'UP', LED displayed value decrease, output voltage increase, when maximum voltage output, LED displayed the number '1'.

(4) Indicate current battery: no key operation within 5s, digital LED will display current battery value: LED displayed number is '9', it means current battery voltage is the highest; if displayed number is '1', it means current battery is lowest.

(5) Shutdown operation:

Press tact switch 'off' for a while, digital LED off, output off.

4. Charge indicator: charging time LED displayed current electric quantity '1-9', decimal point flashing; after full of charge LED displayed number is '9'.

5. Electric quantity indication: unconnected load condition, press any tact switch, LED will indicate current battery electric quantity. Release the button, LED off; electric quantity indicator value 1-9, 9 is the max number.

6. Load: Purely resistive load, resistance: 3-50 ohms, motor load.

7. Operating current: <15mA; standby current: <40uA; output power: 16W MAX; power output efficiency: ≥98%.

8. Max load current:2A

9. Load current indicates: LED display 'E'.
