How can batteries charge faster than they expend energy? doesn't

How can I fill my car's gas tank faster than it empties while driving? doesn't that break the first law of thermodynamics?

it cant
chargers compensate for loads while charging

also capacitors allow faster output than input

Why would it? Batteries are basically just a reversible chemical reaction. It releases energy as electricity in one way, but you can make it run the other way by dumping energy into it. Dump a whole lot of energy into it and you can run it the other way really fast.

Nerd!

You're absolutely right. Someone should call NASA

Don't call (((NASA))) they're in on it.

how can mirrors be real if our eyes aren't real? doesn't that break the first law of thermodynamics?

just stop

No it doesnt.
Batteries can gain/expend energy at any rate that is lower than tgeir blow up current.
Blow up current is defined by equation
P=I^2*R
Where R is battery internal resistance
P is power loss on resistance (blowup power is when the value is high enough to boil electrolite)
I is the blowup current derived from blowup power.

R and P depend on battery type size and design.

they don't

also, the intensity/amperage fluctuates all the fucking time

both charging, both discharging

the values you see on both the battery and the charger are for the nominal cell ... which applies for a brief moment in time.

usually, they're trying to sell stuff in "safe" parameters, to avoid the battery exploding from heat. that is, a charge chip with pre-calculated parameters which should limit the current from the charge irregardless of the charger.

that being said, most phones draw around 0.25-5 A/hour from the battery, while batteries charge around 1-2 A, while the battery is probably actually rated for 4-7A in the factory but shit would explode after few cycles.

at physical level, matter, as it is, doesn't discern between "volts" and "amps" for ceding energy to another object. this is ... from our point of view.

It is very interesting, that illiterates think that the four laws of thermodynamic say something about the speed of energy conversion.

It is even perfectly conform with the laws, that a system that is supposed to change fast (like the breaking of a dam) is slowing down it self (by blocking itself with debris).

the shitposting is pretty unbearable now
