Like Tesla it depends on car and charger. I’m at a new 250kW Tesla charged with 50 miles of range left on battery but max charge rate is 95kW. Just 3/12 but no one is pulling advertised 250kW.
The point was that @"TeslaTap.com" was completely wrong on Porsche’s most advance EV system which is able to charge at all the CCS public chargers.

Anyone who wants a Porsche is going to load that puppy up.
Otherwise what will the Proud Boys at the Country Club/shooting range think?
Never wear white after Memorial Day, hold your pinkie out when drinking tea with the Queen, and always flaunt your Porsche bling to impress the other insecure middle-aged losers, who couldn't afford a Tesla Roadster with SpaceX package.
Grandson, what did I tell you about hanging out online with big boys? You can't do that! You will get all upset again and sit in the corner for half a day. Silly boy. Come to granny I will give you hot chocolate.
I never said a Taycan couldn't charge at any working CCS connection - but that many connections are quite slow. CCS AC charging is very slow, limited to 11 kW on the Taycan, and DC "fast" charging is limited to 50 kW at 400v or 150 kW if you buy the special 400v option. Many CCS connections peak at 150 kW or less. Only the very latest high-power CCS connections support a peak of 270 kW.
Yes, my grandson is very bad boy. It is not very good for his weak brain that he got from his Father. Boy oh boy we will have to do something about this silly boy.
Supplier Delphi Technologies announced last week that it will supply 800-volt inverters for an unnamed automaker's future luxury electric cars.
Delphi now claims that it will be supplying inverters for three out of the top four global premium automakers, indicating a broad shift toward 800V systems for high-end EVs.
The latest supply deal is expected to launch in 2024 across the customer automaker's EV range, a Delphi press release said. It will also mark the introduction of the sixth generation of Delphi's Viper inverter—a component Delphi said enables 800V charging and can greatly reduce charge times compared to today's 400V systems.
800v, 400V, 1000V are irrelevant to charging power and speed. It only used by marketing people who don't have a clue. A 200v system (which doesn't exist) could offer more power and charging speed than a 1000V system. It all depends on the amperage, and without stating amperage and voltage together (i.e. power), the voltage is meaningless. A 5V 2 amp phone charger has 10 times more power than a 1000V 0.001 amp charger.
So anyone starting an 800V system is better than another voltage is totally clueless or more likely purposely being deceptive.
Now at the same power level, an 800V system could be slightly lighter than a 400V system as there is less copper needed for cables, but larger insulation is required, adding weight. The net result is unlikely to make any difference to the range.
400V vs 800v is more akin to getting a car with blue paint vs. grey paint. It really has zero real significance and is more a personal choice by the designers.

Not sure how you "start" an 800V system but the higher voltages, as Tesla as done with its EV's, are done for several good reasons, reduces cost and weight of internal wiring and provides faster charging.
Tesla will likely introduce 800V (or higher) system in the Roadster.

In an EV, probably not. In aviation, there has been a shift from 28VDC power buses to 270VDC, and it was done primarily to save weight.
Naturally 28-270 is far more significant a change than 400-800.
Ok, let's look at this a different way. If the Taycan using 800v is so much better than a Tesla 400v system, why is the Taycan slower to charge and weighs more? The Taycan fails in both key attributes. So based on those details, one would assume 800v is a huge step downward.
Now a choice of 800V or 400V is a design choice, not a marketing advantage (in either direction). Those that claim otherwise are being very deceptive.
Yes, the Taycan consumes more power, but because the Taycan is the most inefficient EV made today, the amount of miles of range accumulated is far slower than any Tesla sold today. So no, it is not all that fast to charge a Taycan, even at 270 kW (not 277 kW).
It is impossible for the Taycan to be "upgraded" to 350 kW, as that requires a 1000V charging system to work on the awful CCS connections. 1000V would cause the Taycan battery to catch fire and blow up.
Sad that a proponent of CCS hasn't a clue how power and voltages work.

Teslatap’s point was that the Porsche doesn’t charge at 800v at most chargers. You know that, yet you choose to misinterpret and call him a liar.
Someday, we’ll know the details of your arrangement to negatively influence Tesla products.
The Porsche 800V system works on EVERY fast DC charger with CCS plug access.

The 800 volt part certainly does not.
You can say, ”The Porsche 800V system can charge at lower voltages on EVERY fast DC charger with CCS plug access.”
You know exactly what you’re saying.

You missed his "Fully Loaded" at the very bottom of his post. I almost made the same mistake. Typical Smart $ss post.

The whole system is 800V and it works just fine at all CCS chargers.

Charging Power = Watts of input power
Charging Speed = Vehicle miles of range per unit of time
Taycan does not charge faster than Model S
Porsche 800V system is fastest charging at 277 kW. Fastest Tesla system is 250kw.
Porsche will upgrade that to 350kW to use the fastest chargers out there, EA’s 350 kW chargers.
It is impossible for the Taycan to be "upgraded" to 350 kW, as that requires a 1000V charging system to work on the awful CCS connections. 1000V would cause the Taycan battery to catch fire and blow up.
