eli5: How do phones “pull” electricity?

584 views

I could be totally wrong about my understanding but I think phones and other devices “pull” the electricity needed to charge their batteries and if you plugged it into a wall plug that couldn’t supply enough juice it could damage the phone. I also hear people talk about some wall plugs charge their phone way faster so my question is can phones or other devices modulate how much they pull if they detect that a plug is capable of supplying more? Enlighten me people of the internet’s!

Yeah. Your local electrical powerplant is pushing those angry pixies into your phone. But it’s doing so through a bunch of filters that make your phone able to handle it.
