My UMC from Juicebox is rated 80 amp but has a 50 amp cord. I would like to replace with a Roadster cord. I would rather buy the blown UMC and remove the cord myself. That way I know everything I need is intact Best, T
A Roadster UMC only charges at 40 amps, so I'm not sure it'd be rated for 70 amps. The Roadster High Power Wall Charger cord is a beast at 70 amps, but those things are very robust and will probably last a very long time. You can get one of these:CS-90 Tesla to J1772 Upgrade Kit | ClipperCreek Vehicle Charging Station and just use that with Henry's CAN.
