THIS INSTRUCTABLE IS ABOUT HOW  U CAN CHARGE ALL OF YOUR CELL PHONES WITH NORAML AA BATTERIES. DURING ONE OF MY SUMMER VACCATION I FORGET MY PHONE  CHARGER AT HOME AND DONT WANT TO SPEND MY MONEY FOR NEW CHARGER. SO I THINK TO CHARGE MY PHONE AT HOME USING A HOME MADE AA BATTERIES CHARGER.SO HERE WE GO--

STEP1)FOLLOWING THING U NEED:-
1)a charger plug,
2)resistor 2
3)cell phone
4) 4 AA batteries AA.
5) wire

STEP2) CONNECT ALL THE 4  BATTERIES TOGETHER SUCH AS POSITIVA OF ONE CELL CONNECT WITH NEGATIVE TERMINAL OF OTHER BATTERY. CONNECT ALL THE 4 AA BATTERIES LIKE THIS ONLY. I USED A BATTERY HOLDER WICH I EXTRACTED FROM MY OLD TOY CAR. I PUTTED ALL THE BATTERIES IN IT


STEP3) CONNECT A WIRE IN POSITIVE TERMINAL OF BATTERIES AND A WIRE IN NEGATIVE TERMINAL OF BATTERIES AFTER U ALL JOIN IT. i.e. in photograph.


STEP4)NOW CONNECT RESISTOR 2 IN POSITIVE WIRE.


STEP5) NOW CONNECT THE POSITIVE WIRE WITH RESISTOR TO ANY WIRE OF CHARGER PLUG AND OTHER WIRE TO OTHER WIRE OF CHARGER PLUG.


STEP5) NOW JUST CONNECT THE CHARGER PLUG TO YOUR CELL PHONE AND SEE HOW IT WORKS.

YOU HAVE JUST MADE THE CHARGER AT HOME BY YOURSELF.HOPE U LIKE IT.
THANK U!!
<p>4AA batteries will give controlled current of 2A directly.</p>
Why to use resistor?
<p>Because its the law.......Ohms Law! Bazinga.</p>
<p>it is very and it charge my phone im 2 mins.</p>
<p>it is very and it charge my phone im 2 mins.</p>
<p>it may damage the phone , cuz it has nothing which controls the current and voltage .</p><p>our chargers are a constant current and constant voltage sources</p>
seems is a little piracy in the instructables today https://www.instructables.com/id/Usual-batteries-charges-CellPhone/
why did use 2 ohm resistor exactely? <br>do u think i can use less than 2 ohm? <br>do u think i can use less than 4 AA batteries? <br> <br>
my bad I did not look at the images that your resistor is 2 ohms
what is the capacity of your resistor? I mean how much does 1 of your resistor hold.?
