Wanting to charge at a friends place that I spend the night at once in a while, and was going to plug into his dryer outlet. Would this cable and adapter work fine? (I would plug the UMC in with the standard 14-50 on it and dial back the car to 24 amps.)

My thinking was the 50 foot cable might come in handy sometime, and this way I don't have to buy the Tesla 30 amp adapter for the UMC. I know I could get a 50 amp cable, but for 50 feet it gets a bit pricy, and I can't see a situation where the extra charging speed would be crucial for me. Figured I would grab this as well, just in case I ever need to plug into 14-50 and use the extension cord (again 24 amp charging from car) Road Power 09529-33-88 50-30-Amp RV Power Adapter - Walmart.com Thanks!
