with a cheap cable
it does not put that voltage into the battery
the voltage going into the phone has absolutely nothing to do with charging the battery
which is what linus was implying halfway between his analogies
Is there a site with saved routers/switches web interfaces were you can look around how they look?`
wow such good results

or just unifi interface whatever is it called
> the voltage going into the phone has absolutely nothing to do with charging the battery
where the fuck do you think the voltage is going
oh i get it gr8 b8 m8
lmao are you this retarded?
unless youre attempting to articulate that the voltage is stepped down to 5v to make more current
no
it's not stepped down to 5v at all lmfao
lipo batteries are charged at 4.2v
we could also argue that you can indeed charge lipos with more voltage too depending on cell configuration and other factors
but indeed per cell voltage is usualy always X
its electrically possible to convert that to 4.2v and use that to vary the current but im not seeing anything more specific than the charger supplies this to the phone
also all quickcharge chips these days afaik negotiate the power so it wont waste that shit for heat like older phone models would have done if they were abused such way (well duhh)
yeah theres a whole request system where the phone tells the charger what it supports and vice verca
i mean sure if you hook up 20v to old nokia 5v 200mah charger... you are gonna see dead phone or lot of heat and angry phone
also is there yet even devices what give out 20v
few years ago afaik there was none really
heres a quick charge controller that can do 20v
Figure 17. NCP4371 State Diagram shows the request part
```Batteries Must Be Specifically Designed to Withstand Fast Charging
A battery is a sensitive electrochemical device. Many factors can damage the battery: temperature, sudden discharging/charging, too many charging cycles, etc. The battery is designed to absorb a specific amount of energy in a specific amount of time, and pushing more energy into it than it can handle damages the battery and shortens its lifespan. In the case of the most commonly used lithium-ion (Li-Ion) batteries, doing this causes lithium plating to form on the anode, which creates dendrites and shortens the battery life.```
there's never going more than 4.2v into a battery
if there was they'd run the risk of exploding
so the current has to vary then
the only reason for the higher voltage is less loss in the cable
in order for more power to go in to the battery you have to increase atleast one of voltage and current. you keep saying the voltage is constant so the current has to change for the charger to put out all these different watt ratings
it looks like varying current is how its done
