Tell me correctly what is voltage? and got a better answer

To put it into perspective, imagine a faucet of water. You need to fill a bucket. Voltage is the height of the faucet over the bucket, amperage is the thickness of the jet in a very rough approximation . If you raise the faucet a couple of hundred meters above the bucket - it will not pour any faster, it will just beat out the bottom.

No, that's not right. The voltage should be 5 volts either way.

Let the resistance of the phone be 1 000 Ohm Then at voltage U= 100 V the charging power P= U²/R= 100²/1000= 10 W When the charging voltage U= 5 V the power P= 5²/1000= 0,025 W, that is the power will be less by 10/0,025= 400 times, not 20 times. 20² times more!

Accumulators are charged with current, not voltage, but different types of accu need different voltages for phone charging is enough < 3,6v, for car battery 13,5-14v depending on charging current and accu characteristics, charging will be faster/slower

Tension is a DIFFERENCE OF POTENTIALS. For example, a tug-of-war with 100 people on one side and 50 on the other All people of equal strength Where will the rope go? -To where there are 100 people. There is a difference of potential-100-50=50.On the wire or something else-motor, light bulb, relay, etc.-there is also a difference of potential. -On one end of the wire, let's say, 1000000 trillion electrons, and on the other only one trillion. Here, this crowd will break towards the smaller number and a current consisting of this very crowd will run along the wire. Two different in number gangs this is the TREATMENT Not electronics, but all gangsterism! And as for the chargers. -In flashlights, with built-in charger, the battery voltage is 3-6 V, and they, during charging, are supplied with 300 V! So what? The main thing for charging the battery is the current that will flow through it. And it, in spite of such a high voltage, will be very small there, thanks to the parts, standing before the battery capacitor of a certain capacity. 300 V would be WITHOUT the battery, but with it it would go right down to 3-6 V.
