I yearn for a powerbank that is capable of 50VDC out, preferably with some 2-2.5A. The smaller the better but I'd look at anything there is.
Any advice?

Context is that I want a powerbank that could be used to charge an electric skateboard in a pinch.

I would like to request some boosts, thank and please you.
