I have a 32 amp Nema 14-30 dryer outlet in my garage. I also didn't want to plug and unplug my car and dryer all the time, so I bought this splitter on Amazon for $69. Parkworld 88603 NEMA 14-30 Splitter. It works like a champ.
a NEMA 14-30 is a 30 amp outlet capable of sustaining 24 amps continuous load, not 32 amps.
