How do you convert 12V to 9V?
To reduce a 12V circuit to 9V, place two resistors in series within the circuit. Find the difference between the two voltages (12V – 9V = 3V) to determine the total amount of resistance needed.
What is the difference between 9V and 12V?
However, there is not much difference between 9V and 12V. It does not take much current to be drawn from the battery before it drops 2V at its terminals. A small mount of extra drop in the wiring and the internal 9V supply drops. After that, the available current from the controller drops quite quickly!
How do I know if my charger is fast?
For the first, it’s as simple as looking at the charger itself. This may have the wattage printed on it (as with Apple chargers) but it might have output(s) quoted as volts and amps. For example, if it says the output is 5V at 3A, then it’s a 15W charger because Watts = Volts * Amps.
