The Harumio adapter has been really easy to purchase though, and the price isn't too bad. I don't understand Tesla's unwillingness to sell it here in the US, but then I don't really understand their CEO either so I'm not too surprised. The Setec adapter was fine while it was the only option - but honestly if an owner's Tesla supports it, the official adapter is by far the superior option - (much) faster potential speeds, lighter, safer and no dependence on an internal processor/battery.
This is purely speculative, but my suspicion is that Tesla hasn't released their CCS adapter in North America because of supply chain problems.
The adapter itself must be manufactured, and if I understand correctly, Tesla has outsourced this task to a third party in Taiwan. They may be having problems keeping up with demand, even with (officially) only Korean sales -- of course, some percentage of those Korean sales are actually coming to North America. Tesla must be aware of this fact, but if manufacturing capacity is beneath what it needs to be, opening sales in the much larger North American market could prove problematic. Long-time Tesla owners know that, even pre-pandemic, the company had a hard time keeping certain items (like the CHAdeMO adapter) in stock in their store. I have little confidence that they'd do any better with the new CCS adapter, once it's released in North America.
The other factor is that not all Teslas support CCS. The
thread on retrofitting this support into older Model 3s presents some evidence that Tesla is planning a retrofit for older cars. (In particular, listings for retrofit kits have appeared in Tesla's catalog, but they aren't currently order-able.) These retrofit kits, however, will require something very similar to the current "Gen4 charge port ECU," and we know that Tesla has been having problems getting the chip that's needed for CCS compatibility for those, since there have been at least two periods after the release of the Gen4 ECU when Tesla shipped stripped-down Gen4 ECUs, which lacked CCS support, in current-production cars. If Tesla is having problems outfitting new cars with CCS support because of chip shortages, there's basically no chance that they'd be able to offer retrofit kits. Of course, Tesla could, in theory, sell the CCS adapter without retrofit kits, for the benefit of owners who
do have CCS support; but they may be reluctant to do so, since that would create a lot of frustration and confusion among owners whose cars lack CCS support.
It's also conceivable that Tesla is currently building up a stockpile of products so that, when they
do release it, there won't be shortages. This, however, is an optimistic take on the matter. Given Tesla's long-standing problems keeping items in stock, I suspect that they'll release it one day and it'll be sold out the next day, and stay that way for weeks.
