eli5, why can’t we have instant phone chargers?

279 views

Hey guys, I don’t understand enough about electronics to answer this, but if my electricity at home is able to power a washing machine.
Should it not be possible to have like a super battery that goes 100% instant, and then release normal current to the phone until it’s charged? More like an instant power bank?

Batteries and other charging electronics are not 100% efficient, some of the energy becomes heat. This is why the phone gets hit when you charge them. So if you increase the charge current the result will be they get overheated.

There is another limiting factor too but heat is a major one.

A washing machine is not instantly changed, it uses electricity on demand. A phone can do that too, you just do not what to have them always plugged in.
