Your concept of electronic physics is skewed.
It's physically impossible to "suck" voltage out at a constant 12v.
CURRENT (or Amperage or "A") can be pulled or sucked. It is NOT pushed by the power source.
On the other hand, VOLTAGE is pushed through the circuit. Voltage is NOT pulled by the load. That's just not how it works.
If the power source isn't PUSHING out 12v, you can't pull 12v out of it.
The only way to push 12v out constantly throughout the entire charged life cycle of the source is to actually use a 12v battery and install a regulator to prevent the power from exceeding the 12v and cut off when the power drops below 12v.
