TT-30 (120V 30A) can only deliver 120 * 30=3.6kW. In actual use it is probably 3kW max for prolonged use. You need a NEMA 14-50 at the least to make use of the charger's full capability.If I often used TT-30 plugs, I'd maybe consider something like this 10kW portable CCS charger: 10kw CCS Combo Portable Charger - EV Fast Charger - ShenZhen SETEC Power Co., Ltd.
In theory, you can use this to take in [email protected]30A and then "DCFC" with that. Here's a demo of this thing (turn on auto-translate subtitles from German->English):
It looks like they're in the ballpark of a few thousand dollars, but could also be handy if you want to hack up a connection from a Tesla HPWC over DCFC, though might be worth getting the 20kW one if you're going to do that on an 80A one, which may or may not be possible with existing adapters.
Second thought. Is DCFC at 10kw worth that much trouble?
