Batteries that charge in 1 minute
It takes approx one minute to fill up the gas tank of your car to have enough fuel to drive like 8 hours. So you could say that the charge vs consume ratio is roughly 1:500.
I'm looking for batteries in all forms and sizes - AA, AAA, mobile phone, camera, power banks, etc - that have a similar ratio.
(It's more of a concept than a product or service, but overall, I'm willing to spend $25 per month to have fast-charging batteries for all devices.)
