What good is 19.6kw charging capacity if Porsche doesn't have way of charging on AC with Porsche Connect?

no doubt it’s a great feature - I routinely charge my Wife’s 2017 Model X @ 72 amps - it’s wonderful to come in from a 120 mile drive and fill it up in 3 hours or less - but I installed it because I value the charge time at home this offers - I had _NO_ delusions that this would be beneficial for me when away from home - I do find the occasionally 80 amp charger in the wild, and it‘s nice, but not anything you can rely on.

the good news here is that the FastDC charging network is being built out - and the slowest FastDC charges tend to be 25 kw, with a lot of charger at 50 kW, and an ever increasing installed base of 150/350 kW chargers…

so the “need” for 19.2 kW AC/L2 chargers is being supplemented by a growing installed base of FastDC chargers that are much faster…

that is another reason while this feature is questionable in the US market - FastDC is the clear path forward and this option plays no role in that charging system.

Thanks to everyone for the quick and thorough answers. And thanks for your patience as I am a newbie to Porsche and to EVs. But everything you said makes sense to me. Two more questions(that I'm sure is obvious to others)
1) If I were to get the 19.6kw charger option, would it be "smart enough" to use a 40amp supply if that was what was connected? In other words, if the car had this option but I went to L2 public charger that was running at 40amps, could I still use it, albeit at the slower charge rate?
2) Do most public chargers have just a type 2 socket (I would need my PMCC) or do they have a cable with a j1772?

In the US, almost all chargers have cables. The car and the charger negotiate whatever the most appropriate rate of charge is. You'll get the max charge the EVSE can supply up to whatever the car will take at a particular moment. So yes, you'll get 40A from a 40A charger.

Thank you. That's what I thought. So, the only "downside" of getting the 19.6kw is that if I don't upgrade my home to 100amp and I don't find many chargers with 100amp in the wild, then I've wasted $1680 on the option. But the car will still charge as if I hadn't purchased the option. Right?

the massage seats are a much better use of $1860 - and they will be used more often - my wife after experiencing them in the Taycan have made them a “must have” for her Cayenne eHybrid…

seriously $1860 that will provide nearly ZERO value in the North american market - people have argued over the $700 400V/150 kW option and determined it’ snot work it - honeslty it’s a much better bet that you’ll run into a 400V 150kW charger in the wild than a 19.2 kW charger in the wild - and the 400V/150kW option is cheaper…

unless you’re going to have your home/work charger setup for this, or you KNOW chargers you plan to use that are more than 48 amps - this option will be used less than vritually any other option on your Taycan.

also there are 3 costs here - not just the option:
  1. cost of the option from Porsche
  2. cost to install a 100 amp circuit in your home
  3. cost to purchase/install a 100 amp EVSE (charger)
I’d be surprised if the total cost of all 3 items is less than $7500 when you add it all up.
