Instructions for making backup batteries from an orange, charging nearly 40% of the battery for iPhone

Orange, a popular fruit, but certainly no one expected to use an orange to fully charge 40% of the battery for the iPhone 5S.

If the "dear" phone suddenly runs out of battery, you have a need to use it but nothing to charge the device. You can build a simple backup battery charger that can charge up to 40% of the battery from indoor materials: orange and a little vinegar.

Prepare

1. An orange
2. Two wires
3. A USB jack

Implementation steps

Step 1:

Cut the orange halves into 2 halves horizontally.

Step 2:

Pour rice vinegar on two halves of the orange.

Put 2 halves together and fix with adhesive tape.

Step 3:

Plug 2 wires in turn into 2 halves of the orange to form 2 electrodes.

Connect the cord that plugs into the 2 red and black wires (power cord) of the USB jack.

So you have an extremely simple phone battery charger. Even this homemade phone charger can be reused many times, after the orange has fully charged the iPhone, you can pour more vinegar and put orange fruit in the freezer fridge for about 2 hours to The orange has a power return that can continue to charge the battery.

Good luck!
