Just grab a spring from a pen, and tape it to that little metal nub on the side of the charger, as shown in the photo above. Then line up your 9 volt battery, with the big (negative) battery terminal on the spring, and the positive (smaller) terminal touching the button in the center of the car charger. Then just hold it in place.

Why does steel wool burn with a 9-volt battery?
When the strands of steel wool touch both terminals of the battery, they will complete the circuit and cause electricity to flow. This will heat up the steel wool, which will cause it to react with the oxygen in the air, or in other words, BURN!
What voltage is a car battery?
12.6 voltsWith the engine off, the fully charged car battery voltage will measure 12.6 volts. This is known as “resting voltage.” When the engine is running, battery voltage will typically rise to 13.5 to 14.5 volts. The battery is boosted to these higher levels by the alternator.
What is a PP9 battery?
The PP9 battery is commonly used in classic radios and marine lanterns. Made up of carbon-zinc chemistry, these hardwearing batteries are one of the most cost-effective kinds of disposable battery.
Step 1: Materials
The picture shows the components needed to assemble the charger, including one empty case from an old toothpaste, that can be useful to put the charger inside in the future, in an updated step... And the list of components and materials is: 1 old 9v battery 1 USB port type A (female) 1 Regulator 7805 1 green LED 3 resistors 220R 1 empty case (optional) solder wires.
Step 2: Schematic
In the computer, using any electronic circuit maker, can be made one scheme like the one in the picture, where I've added a diagram of the pinout of the regulator 7805 and of the USB port.
Step 3: Solder the Components
After the disassemble the old battery, the base with the connectors it's useful to solder the components on, starting with the Ground pin of 7805 (pin 2), soldering it directly to the negative pole. Pins 1 and 3 must be softly lifted up, in order to solder the other components, according with the scheme of the previous step. One resistor is connectd in the positive pole with a minor size than the base, in order to connect to the Anode of the LED, making a series from the positive 9V pole to Pin 1 of the Regulator. Pin 3 of the regulator (output 5V) is then connected directly to pin 1 of the USB port, soldering a wire. The Data pins of the USB connector are connected with 2 pull-up resistors to the pin 3 of the regulator To finish, pin 4 of the USB port it's connected with a wire to the negative pole of the battery, where it's already connected pin 2 of the regulator. The result must be like shows the picture, where we can see the charger charging the battery of my mobile and we can read in portuguese: "Bateria está sendo carregada" - Battery is being charged...
Step 4: Final Product
And the final product must be like it's shown in the picture! Now I have one mini-charger, handy to have in the pocket with a battery, for the urgencies. ;)
How long will it take?
It took me 7 minutes to charge my iPhone SE from 60 percent to 67 percent charged. The exact time it takes may vary, depending on how charged your phone is and how much juice is left in the 9-volt.
How much of a charge will I get?
A typical 9 volt battery has 500 milli-Ampere hours (mAh). Compare that to the size of your phone’s battery. A few examples:
