Once you have the Tesla 16A red UMC adaptor, you have two ranges of adaptors to choose from: the “Standard” range and the “Compact” range.
Both ranges allow for the full three-phase power at 16A / 11kW so there is no difference in charging speed. The key benefits the Compact system has to offer are size, waterproofness, ease of use and cross-compatibility with Gen2 UMC (with the Compact Blue UMC adaptor).
