A what now? I haven't seen anything CCS related in the US. Is that a European accessory? Don't all Teslas outside the US ship with CCS standard?
The US Teslas come with a J1772-to-Tesla adapter so you can use L2 Chargers.
There is a ChaDeMo-to-Teska adapter for $400. No idea why anyone would want this though, ChaDeMo is rare and, in my experience with my Leaf, often broken.
ChDeMo is a better connection in some regards (can feed energy back to the grid for example), but they are a lot fiddlier than CCS and Type2, which are just huge chunks of thick plastic.
Teslas outside of the US have shipped with CCS since early 2019. Older Teslas had the proprietary port.
What is a "Tesla Level 2"? There exists an adapter to convert CCS to the proprietary Tesla connector but that's not L2.
