Can someone explain fast charging to me?

[Indus Monk]

There's a few things i wanted to know about fast charging:

1. How does it work?(PS keep it simple. I barely understood high school physics and almost failed at it)
2. is this technology bad for your battery?
3. How does wireless charging work? is it similar to a slayer exciter circuit?(I saw a video on this where a guy made the circuit with a coil that was supposed to be used for making a mini tesla coil. He bought a CFL bulb near it, and it turned itself on wirelessly!)
4. Link to slayer Exciter Circuit (WARNING: HILARIOUS A.F.)

Don't Grill me if i am wrong anywhere. I am god's biggest failure as a human. And please, keep it simple but detailed

1. Fast charging = pushing more amps into the battery, making the pixies in it dance faster

2. debated among battery aficionados. depends on the battery quality, imo. if it has internal protection against overcurrent, it should be fine (if it doesn't, chances are it'll go boom-boom)

3. singing pixies in the charging base amuse pixies in the phone battery through a special "pixie juice receiver"

Didnt skip on the keeping it simple part.

1 more amps = faster charge

2 more amps = faster electrolyte degradation = shorter lifespan

3 electromagnetic induction allows short range energy transfer, this is not "electricity" transfer, its an electromagnetic field, which can ligth up CFL bulbs

wireless charging works in the same way but instead of a CFL bulb there is a second coil (in the phone) which turns the electromagnetic field back into usable electricity

It seemed more than appropriate to give an AvE-style explanation D:

i see... but i have seen chargers outputting higher than 5 volts, is that because of the fact that ampere is proportionate to resistance multiplied by voltage?

canadian dude that makes videos on the youtubes. pretty funny guy, if you're into mechanical stuff mostly (has some electronics videos aswell, but not all that many)

increasing voltage allowed for more amps to flow

due to resistance, you can provide a phone with 5v 100A supply but it will only charge at like 2A or something whatever normal is

so increasing voltage allows for more amps to get to the phone

That ElectroBOOM guy is a great Youtuber - he tries teaching people stuff, with some humor.

Voltage is just the difference of potential that would drive one ampere of current against one ohm resistance.

 

Almost all phones these days only support a 5V input if you see a 6V or higher charger its most likely not for a phone

this... is a charger for a lenovo phone (vibe P1) that i happen to have, how do you explain this!

 

And how is it able to output the same amperage at varying voltages?

That is a USB charger stating it can support devices that need up to a 12V input , i didn't even realize Lenovo made phones and the phone most likely only supports a 2A at 5.2V

they do, and they sell them exclusively in asia
