#ZeroesAreImportant #MathsIsHard #UnitsAreTricky
I saw an advert for a power bank claiming 9000000mAh, i.e. 9000Ah, easily enough to drive an EV until I need my next coffee stop.

So I added a zero to the price and searched. Yup. Enough energy to drive an EV for a month or two. In my pocket! Groovy :-)

This is Ebay and oddly I do almost all my online shopping there. 2 disputes in thousands of orders :-)
