eli5: Why does it take a long time to charge electronics? Why can’t there just be a surge of electricity sent to the battery to instantly recharge it?
In: 3
If you send too much electricity into a battery, it gets hot. Getting hot means energy is being wasted, which is bad. And getting too hot too often reduces battery lifespan (as in “less years”), which is also bad. So, maybe it could be done, but you’d have useless batteries faster.
