A long time ago (over a year), I was probably perusing this very website and saw a photo thread (i.e., a thread with photos!) about a Tesla owner that had cobbled together a circuit box that allowed him to plug in TWO NEMA 14-50 cables and get 80A charging speed. This was way before the Supercharging network was as robust as it is today, so I don't know if there is any need. But thinking about it, the Tesla owner was using an RV park to charge and this was likely an emergency situation. In that case, using 2 NEMA 14-50's together would certainly allow trip continuance. Does any know what I'm talking about? Is this something owners use or have heard of? I'm not an owner (hope to be, soon) and am somewhat paranoid about running out of range. I'm thinking a 50-amp extension cord (I know, I know, not recommended) would be a good idea, as might this device.
