I posted before about getting a long 'regular' extension cable (and bought a 100ft one from amazon... that I may now return, based on this). This morning behind pictures my fiance had hung up in the kitchen, I found this! Now, I would like to buy an extension cord for this and the 'official' tesla adapter to use with the UMC. My question is that I can't seem to find many 14-30 extension cables online, the most promising one I've seen is this: Conntek RU1430PR NEMA 14-30 Dryer / Range Extension Cords Does anyone have experience/recommendations for a 14-30 extension cord? I would likely need a 50, but I *might* be able to get away with a 25/35 foot (will have to remeasure later, was too dark this morning). I did see posts about adapter/cords to a 14-50, but I'd rather leave it native end-to-end and not mess with setting amps, if possible. Thanks!
