Hii friend,

This is a DIY mobile power bank.By this power bank you can charge your all mobile phones.It's like a pocket power bank.

But in this power bank you can only charge 100% battery of button phones not of android phones.

Let's get started,

Step 1: Take All Components As Shown Below With Pictures -

(1.)Battery - 9V (1P)

(2.)Connector (1P)

(3.)Voltage regulator - 7805

(4.)Resistor - 1K

(5.)LED - 3V

(6.)PN junction diode - 1N4007

(7.)Switch

(8.)Female USB Code

Step 2: Connect All Components As Shown Its Circuit Diagram

Step 3: Connect Negative of Diode to the USB Code Wire

Step 4: Bent 3rd Pin of the Voltage Regulator and Connect It to the Positive Wire of the Diode

Step 5: Now Connect Positive Wire of Battery Connector to the Switch

Step 6: Connect Output of +ve Switch Wire to the First Pin of Voltage Regulator and the -ve Wire of Battery Connector to the 2nd Pin of the Voltage Regulator

Step 7: Now Connect Negative Wire of 2nd Pin of Voltage Regulator to the Negative Wire of Female USB Code

Step 8: Solder a 1K Resistor to the Positive of the LED

Step 9: Solder a Resistor Wire of LED to the 3rd Pin of the Voltage Regulator and Negetive Pin of LED to the Negetive of Female USB Code

Step 10: Now Our Circuit Is Ready and Steech That Circuit to the Battery Like This

Step 11: Insert Any USB Data Cable to the Female USB Port and Charge Mobile Phones

Thank you
