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

276 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?

Think of your battery as an above ground swimming pool. Once full, you have a large volume to slowly take water out as you need. The problem is… it takes a long time to refill.

Sure, filling it with a fire hose is a lot faster than a garden hose – but there is a limit. Try dumping in 1000 gallons all at once from a helicopter and you are going to have a bad time. It is dangerous, will damage the pool, and water will get everywhere!

The trick with batteries (and pools), is to have a large volume that you can quickly fill and store for later use. The technology is getting better, but there will always be limits and tradeoffs.

There’s a big difference between using the movement of electrons, which is how your washing machine is working, and storing electrical energy. Think of it like staring a water pump. It’ll move water almost instantly, but if you want to use that to fill your pool it’ll take some time. Intense scientific research is ongoing to figure out how to fill that pool faster for you.
