Similar diameter to a quad-18650 beer can, but obviously a nominal 15mm longer. So it could feasibly work with revised existing designs provided the tube is extended and accommodation made for different contacts.All in all I think this size won't be easily adaptable to existing devices it will take a new size of device to properly house it.
However, I'm aware that these formfactors are not terribly common, thus clean sheet designs are likely.
In the event the formfactor gains traction outside of Tesla (and is made available with the claimed advances), the appeal may be the same that Tesla sought: reduced complexity that comes with lower cell count. Possibly not relevant in to the power tool industry as we know it today, but with the growth of 'lithium power stations' industry is moving past the boundaries of laptops, power tools, and battery banks.I think overall the price and power density and cost per watt hour would be the main consideration for battery packs as industry is well used to scads of 18650s in a brick to power everything these days so unless the 4680 offers higher power density or huge current outputs is needed current 18650 and 21700 packs would suffice already.
