ummmmm - another case of Porsche being conservative with their specs…my 2020 Taycan charging in my garage…Porsche's official specs indicate 9.6 kW maximum charge rate (40 amps)
https://www.porsche.com/usa/models/taycan/taycan-models/
1st picture below shows that Taycan charging from the Porsche Mobile Connect charger plugged into a NEMA 14-50 plug - 8.68 kW as expected from a 9.6 kW 40/50 amp circuit - car charged last night as expected no problems…
woke up this morning and decide to play around - I'm a long time EV owner and Tesla owner and I have a multi-charger shared circuit Tesla L2 charging setup in my home (4 chargers "sharing" a 100 amp circuit - 80 amp maximum charge rate)…
So I got out my JDApter and plugged in the Taycan to charge - I know this works from various test drives - but I never paid attention to the actual charge rate…
ummmm based on this picture my Taycan has come with a 11 kW (48 amp) charger just like in Europe…note the 10.46 kW charge rate listed below when it's plugged into my 80 amp Tesla Wall charger…
now Porsche documents the maximum charge rate for the North America Taycan at 9.6 kW - that's exactly expected for 40 amp charge rate (50 amp breaker) - but when I plug my Taycan into my Tesla L2 chargers I'm getting what would be expected for an 11 kW charge rate (or 48 amps [60 amp breaker])
I'm guessing Porsche is using the same AC/DC converter for European models and US Models - and they document the US max rate at 9.6 kW for the following reasons:
now if you want to have a charger that can charge your Taycan at 48 amps there are two chargers that I could recommend…
hmmm - update the Porsche spec's page?

I'm guessing Porsche is using the same AC/DC converter for European models and US Models - and they document the US max rate at 9.6 kW for the following reasons:
- Their Mobile Charger which is NEMA plug based maxes out at 40 amps (because there are no 60 amp NEMA plugs in North America - hardwired only)
- Most public chargers are 30 amps anyways
- The vast vast vast majority of J-1772 chargers on the market are 40 amps or less
- Any charge rate above 40 amps would require a "hardwired" charger and therefore is not "mobile"
- They may change supply parts at some point in the future and truly limit the car's onboard charger to 40 amps…since that matches the spec.
- Simplicity - charging is complex enough and confuses most people - why document a charge rate that's more than the charger Porsche provides can handle - simplify the message - buy our car, buy our charger, plug it into the wall and you'll get the maximum 40 amp L2 charge rate
- vs a message, of well if you buy our charger we only do 9.6 kW, but the car can do 11 kW, but to get that you'll have to buy a charger from someone else and it will have to hardwired, and can't be put in the car and carried around with you…yadddda yaddda yaddddaa - tooo complex!!!
now if you want to have a charger that can charge your Taycan at 48 amps there are two chargers that I could recommend…
- Tesla Wall Connector (gen 1, gen 2, or gen 3) - they can be configured for a 60 amp breaker, 48 amp charge rate, or 11/12 kW maximum charge rate - again this will be hardwired connection - and will not be mobile - and it is the Tesla Wall Charger - NOT the Tesla UMC that you need.
- ClipperCreek HCS-60 - it requires a hardwired install & 60 amp breaker but will charge your Taycan at close to 10.46 kW vs. the 8.6 kW maximum from the Porsche Mobile Connect charger.
hmmm - update the Porsche spec's page?
