> “It charges so fast it’s basically a super capacitor,” Nicol claimed. “It charges an iPhone coin cell in less than 10 seconds.”

Are iPhone batteries considered coin cells? Isn't a coin cell like the ones shown here https://en.wikipedia.org/wiki/Button_cell which are much smaller in capacity? If he is indeed referring to a 2000-4000mAh battery size then that is amazing.

Nah, that just doesn't make any sense at all.

It even contradicts their own numbers, which calculated the charge time for an average phone to 1 - 5 minutes [0].

IMO this article is just a hot mess cobbled together by someone who doesn't have the faintest idea about what he's even writing about.

Well it's a quote, so the author of the article didn't write the claim. There's another article out there which inserts a word: "iPhone sized coin cell", which makes a little more sense.

The design of the iPhone and coin cell are similar. The iPhone battery is essentially a wrapped up coin cell. https://m.youtube.com/watch?v=RTjy2eFHzRc

In comparison a package battery like in an EV is made up of many individual cells to provide higher voltages. An iPhone can run on 3 or 4 volts, but a Tesla cannot.
