Yes, the voltage does affect battery charging. Electrons move from the negative end to the positive end when charging a battery. This requires a voltage difference between the charger and the battery. Nowadays, almost all smartphones and smart devices use Lithium-ion batteries.

The main job of the controller is to find and track the unique value of duty cycle that results in maximum charge current going into the battery. As a practical matter, the maximum power voltage point of a solar panel does not change much with changes in lighting or changes in temperature. So the solar panel voltage will be relatively constant.

For example, a DC voltage won''t push current through a capacitor regardless of its strength (up to dielectric breakdown, of course) Are they both the potential energy of a coulomb and the "push" of the current? For a resistor this is approximately correct, except that it is the change in voltage rather than the voltage itself.

$begingroup$ How much voltage is the supply actually producing?

The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current. battery: A device that produces electricity by a chemical reaction between two substances. current: The time rate of flow of electric charge.
When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current.
Battery A has a voltage of 6 volts and a current of 2 amps, while Battery B also has a voltage of 6 volts and a current of 2 amps. When connected in series, the total voltage would be 12 volts, and the total current would remain at 2 amps. Advantages and Disadvantages of Series Connections
When batteries are connected in series, the voltages of the individual batteries add up, resulting in a higher overall voltage. For example, if two 6-volt batteries are connected in series, the total voltage would be 12 volts. Effects of Series Connections on Current In a series connection, the current remains constant throughout the batteries.
“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that's what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).
