For instance, it could have a 50AMP NEMA14-50 to plug in at campgrounds and supply 10kW+ charging through the DC port?
Perhaps also a J1772 adapter as there are public Tesla HPCs being converted to J1772 around, and they can offer, 32A, 40A, and higher. The included portable EVSE (even with the 240V mod) can only draw a tiny fraction of that.
If someone built a box with NEMA14-50 and J1772 and could output 10kW+ to the L3 I would certainly buy one.
As soon as the CHAdeMO protocol is available to the public, I know of at least one company that will do their best to manufacture one. I spoke with them a bit a couple months ago and we felt that starting with a 12 kW version would probably be the most popular since it would only require a 50 amp outlet.
