Hi, when you are stranded in a place where there is no electricity and your phone is running out of charge and you want to make an emergency call!,

Tadaaa!! here are the hacks for charging your phone without your charger or electricity.

I live in Chennai and I used this hack to make an emergency call when we were affected by flood previous year, There was power cut continuously for about 120 hours(5 days) during floods. This hack had worked out for me so I'm sharing with you.

Note: *Using both hacks you can charge up-to 20%(single time) on an average. You can get that much amount of charge even from used batteries for feature phones ( but mAh<1100), But for smart phones you need to put some EXTRA like using NEW long life batteries.

(*)-Values mentioned may vary depending upon the mAh of phone, Type of battery and adapter(if) that you use.

Step 1: CARRY WITH YOU

  • 9V BATTERY
  • CAR PHONE CHARGER
  • USB CABLE
  • KEY(I used wire)

Step 2: CONNECT PHONE WITH CAR ADAPTER

Step 3:

Polarity of terminals of car adapter is clearly shown in the pictures, bottom BUTTON type is +(positive) while side RING type is - (negative).

Connect one wire to the negative terminal to close circuit with battery OR USE KEY TO CONNECT NEGATIVE TERMINAL WITH BATTERY.

Step 4: IF YOU USE KEY

Step 5: CLOSE THE CIRCUIT, CHARGING!!

Connect those terminals with 9 V battery closing the circuit with either wire or with key.

VOILÀ!

IT'S CHARGING AND NOW YOU CAN MAKE YOUR EMERGENCY CALL!

Step 6: HACK #2:USING AA SIZED BATTERIES

If you don't have 9 V battery don't worry and try to get some AA sized batteries (I recommend Alkaline or heavy duty) from your other devices like cameras, mp3 player, flash light,etc. and start charging your phone using the below instructions.

Step 7: WHAT YOU NEED

  • 3*AA BATTERIES
  • CHARGING CABLE
  • CONDUCTING METAL PIECES
  • INSULATION TAPE

Step 8: CONNECT THEM IN SERIES CONFIGURATION!

Step 9: ATTACH THOSE METAL PIECES ON TOP AND BOTTOM SO AS TO MAKE IT IN SERIES CONFIGURATION

Step 10:

Before connecting, cut the usb edge.

follow the pictures for instructions,

I have connected OTG and then connected it using spare usb if you want you can also follow the same to save your charging cable from cutting it. Even if you have no other option than cutting your charging cable you can Fix it using SUGRU after usage.

After cutting, Inside USB: RED is +(POSITIVE) while BLACK is -(NEGATIVE) connect them correspondingly to the battery terminals.

Step 11: CHARGING!!

VOILÀ!

This hack can give you enough amount of charge in your phone with which you can make an emergency call. Remember, I wouldn’t go around charging your phone using this method on a daily basis but in an emergency or a no other choice situation this is a great alternative way to charge your cell phone.

    Thanks for this :)

    I use #1 trick in my Motorcycle. Attache battery wires and add a On/Off button.

    that's a good one, I thought of that before, but didn't think about using the car charger to get to the + - leads. Question, what if the only battery was a car battery and you were stranded from a car problem (but battery is okay). Would that charge or fry the cable? Can you use a make shift resistor if the voltage is too high?

    Its not the voltage but the amps of car battery which very high for the fuse capacity of your car charger. So you can't use car battery directly. Yes of course check this link for

    charging phone from car battery

    The fuse is to protect the circuit of the charging wire. If it gets grounded some how by accident, it will pop the fuse instead of melting the wire and possibly causing a fire. Connecting directly to your car battery is totally fine. Connect it as he has done in this instructable.

    Connecting it directly to a car battery is the same as plugging it into your cigarette lighter socket. In other words, it's totally fine to connect it directly.

    The awesome news in this situation is that your cigarette lighter likely works if the battery works.

    If you had a car battery and needed to charge a phone you could probably get away with the USB adapter, two wires, and some jumper cables. You don't want to be holding the thing that might blow up, so I'd want to be able to distance myself from the USB adapter while making the positive connection.
    1 battery ground
    2 usb ground
    3 usb positive
    4 Visual check between USB positive and ground (no touching)
    5 Battery positive.
    6 USB explodes or phone charges =) (Phone does not explode unless samsung for unrelated reasons)
