Um, it's used pretty much all the time by everyone. What?
I don't think the USB cables are as big an issue, since you can just buy those from anyone, right?
Yes.
Why do people talk like panasonic is the only battery supplier forever? Musk will be sourcing batteries in china from chinese companies. This has been stated over and over.
if you want to debate how those firms will perform on supplying quality batteries at scale, then debate that, but dont debate whether Panasonic will be able to solve all the battery problems into 2020 for Tesla since no one ever said they would.
Also, Musk said things are back on track on GF battery production, so I am assuming that supply should be fine for Q2/Q3 for now.
