A battery is a very quick negative voltage source. In a 9V battery, there are two terminals: anode for positive voltage and cathode for negative voltage. As most devices are designed for positive voltage supply, the negative terminal serves as a ground. Here when the negative terminal is used as ground, electrons are not returning.
The two basic modes of operation of a bench power supply are: Constant current: In a constant current setting, the power supply will retain the preset current despite fluctuations in resistance. Constant voltage: When the supply is configured to constant voltage, the voltage will be maintained no matter how high the resistance.
C1 and C2 simply try to keep that voltage steady as the power supply wobbles up and down slightly, but asside from that, they aren''t much help. ... uses a single battery and a voltage divider to create a "virtual ground" (VGND). Its the same solution using a single battery. Disregard the capacitors and I think you can understand it better.

In CC mode, the DC output current holds constant by the power supply when the output current reaches the current limit setting. The power supply then switches from CV to CC mode. If, however, the power consumption reaches the set maximum power value, the device will switch automatically to power limit (CP) where Vout X Iout = Plimit.

voltages are not easily compared if one is AC and the other DC. The real question is Why don''t you use the battery of your car? It provides 12V already and is so much easier than setting up another battery, converting it to AC just to plug in the power supply of the device that goes back to 12V.
Actually, running through an MPPT charge controller can get more watts into the battery than directly connecting the power supply to the battery, because the supply is limited in output amperage, but should be able to up the voltage to 30 or more, and the cc can regulate that down to battery voltage. ... Set the voltage first, connect to the ...
Switch mode power supplies are an alternative to the traditional linear AC – DC voltage power supply units. ... Once you have calculated the system load, it is best practice to derate the calculation by 10-20%, as a battery will stop working at a set voltage before it is fully drained, so in our example, it would be safe to assume a 7.5-8.5 ...

Since the VSYS pin needs a voltage in the range of 1.8V to 5.5V, we can step down the voltage from 9V battery to 3.3V or 5V in order to power Pico. We shall see how we can convert the voltage from the 9V battery to 5V using a voltage regulator IC such as the LM7805. Powering Pico with 5V has some advantages such as:

Connect your battery to the inverter, charge controller, and charging source. Next, connect your home battery backup system to your home''s existing wiring using a transfer switch (or power input if available). Once everything is hooked up, your home electrical system should draw from the backup battery the next time a power outage occurs.
The devices work by not being constant current and constant voltage at the same time. You set a voltage (V) for the output. You set a current (A)for the output. It will supply constant V for any current up to A. When the current your circuit draws goes above A, then it will reduce the voltage to keep A at the value set. Example: V set to 10V; A ...
