The Tesla UMCs

As of May 2019, Tesla has now started shipping cars with a new Generation 2 UMC (Universal Mobile Connector). All EU Model 3 cars also come with this new UMC.

The older Gen1 UMCs have a captive pigtail lead coming out of them, going to a proprietary connector.

The newer Gen2 UMCs do not have a captive pigtail lead. Instead, the proprietary connector is part of the actual UMC unit.

There is also a new Gen3 UMC available as a spare part and it natively supports 16A three-phase power and comes with the red commando fitted (no adaptor required).

The proprietary connectors differ between Gen1 and Gen2 UMCs are are not interchangeable.

Xavelec provides adaptors for all types of UMC as well as a Compact connector system that can be used with either UMC with the corresponding adaptor.

The table below lists the specifications and highlights the key differences between Gen1, Gen2 and Gen3 UMCs.

The charging speeds mentioned are approximate values and will vary, but offer a reference point.
