My vote is it should be free for anyone who bought before the price drop

It just comes down to length and weight. There might be a sweet spot where just a foot of extension that is fat enough to not need active cooling is not too heavy, but 2 feet would have to be so much metal that it would be 35 lbs.I still don't see how we can get an extension cable for DCFC when the rest of the cable has to be actively cooled. That will be very interesting, not sure I want to go for that.
People don’t realize how much current is required to deliver 150kW, given our Lightning’s relatively low pack voltage (low-mid 300v). Any adapter that passes less than 500A will prove to be a disappointment, and its users will probably accuse Tesla of derating their Superchargers…You could do the extension cable with thicker wires. Thicker wires means less losses and more heating, but also more weight and cost.
For the AtoZ adapter - the 300A limit would be a pretty big bottleneck and limit you to around 100kW charging in the real world. That is a pretty big speed cut vs. what EA / EVgo can do when they are working right. The good ole speed vs. reliability argument.
Lightning is not the only Ford EV.Not that many Ford Lightnings have been sold.
Ford should give the adaptor Free to current owners.
Going forward, the adaptor should be included in the price for new sales.
It’s the only one we care about. .Lightning is not the only Ford EV.
I thought the max amperage that the Lightning would request was 475, and only for a few minutes?People don’t realize how much current is required to deliver 150kW, given our Lightning’s relatively low pack voltage (low-mid 300v).

You never want to run power equipment right to the limit of capacity, so you would want at least a 500A limit to support that 475A draw.I thought the max amperage that the Lightning would request was 475, and only for a few minutes?
I wasn’t aware of that spec (where did you find the 475A number?); I got my impression by watching OBD data in Car Scanner app. Regardless of 475A or 500A max, an adapter that only passes 250A-350A isn’t going to be capable of much more than 100kW; meaning, longer charge times!I thought the max amperage that the Lightning would request was 475, and only for a few minutes?
