> 1. Tesla already opened up the NACS connector for others to use. We don't know the detail yet but the license fee is probably minimal if Ford and GM agree to join. So if I want to purchase a NACS charger for my house, besides Tesla, what are my options? > 2. the CSS1 connector is monstrous compare to NACS, with design deficiencies that are more or less not fixable. Besides size apparently, what are these "design deficiencies" that you speak of?

Tesla is in the process of ratifying it as an open standard. Other manufacturers will be forthcoming, but Tesla is it at the moment. It’s kind of the chicken and egg problem, but should work itself out since they seem adamant about making it a free, open standard.

  > Tesla is in the process of ratifying it as an open standard. You'll forgive me if I don't believe them, considering their last PR release pre-2021 about it being an "open standard" included the fine print of Tesla gaining permanent access to all of your IP if you used it.

Lectron has one, although I don't know if it's as good as Tesla's

For one, the locking component, that prevents yanking the handle out while 350kw is flowing through it (an obvious arcing and fire hazard), is on the CCS handle itself, vs NACS where the charge handle just has a small hole and the locking mechanism is part of the car. This plastic locking mechanism on a CCS handle can break if it's abused, leaving it in an unsafe state to use

  I haven't seen one made of plastic. All the ones I've handled have been metal. The locking mechanism can also break on the car. Its way more challenging to fix. Also, I'd prefer to always be able to quickly and easily manually unlatch it, which isn't true on a Tesla. On most models the manual release is tucked pretty deep in the car.

    Yes, the car part can break, but CCS1 requires a vehicle side latch too. It has to capture the CCS latch and is often a little flipper near the top of the car's inlet.
