What EV Charger Do You Need for a 2020 Porsche Taycan Turbo S?
A full charge takes 8.7 hours at the car's maximum Level 2 speed, which easily fits a standard sleep schedule. You need a 48 amp EVSE to hit this speed. Plug it in at bedtime, and the 95.8 kWh battery is full by morning.
The numbers
| Maximum AC charging rate | 11.0 kW (48 A) |
|---|---|
| Charger size to buy | 48 A |
| Circuit breaker required | 60 A |
| Outlet / connection | hardwired (a 48 A EVSE must be hardwired -- no household receptacle is rated for it) |
| Charge port | J1772 |
| Full charge on Level 2 | about 8.7 hours |
| Range added per hour (Level 2) | about 22 miles |
| Full charge on a 120 V outlet | about 67 hours |
| Range added per hour (120 V) | about 2.9 miles |
| EPA rated range | 192 miles |
| Energy for a full charge | about 95.8 kWh at the wall |
Why 48 amps and not more
Your car accepts up to 48 amps of alternating current through its onboard charger. Buying a larger charger yields no speed benefit because the vehicle limits current draw to 48 amps. Feeding the car fewer amps extends your charging time. The EPA test rates the car at 10.5 hours for a full charge because standard compliance testing does not always run at the car's absolute peak rate. Stick with a 48 amp unit to match the maximum onboard capacity.
What the install involves
A 48 amp EVSE must be hardwired because no household receptacle is rated for that continuous load. Have a licensed electrician run a dedicated circuit with a 60 amp breaker. The technician must check your main electrical panel for spare capacity before landing the wires. Hardwiring eliminates potential failure points found in high amperage plug connections.

Common questions
- Can I use a standard wall outlet?
- Level 1 charging on a standard household outlet takes 67 hours for a full battery. It delivers only 2.9 miles of range per hour. You will want a Level 2 setup for daily driving.
- What connector does the car use?
- The vehicle uses a standard J1772 connector for AC Level 2 charging. Every non Tesla EV sold in North America through 2024 uses this plug format. You can also use adapters for Tesla destination hardware.
- Will a 50 amp charger charge faster than a 48 amp charger?
- No, because the car caps its AC intake at 48 amps. Any extra amperage from the supply equipment goes unused. Your charging speed stays capped at 22 miles per hour.
- Why does the EPA estimate take longer?
- The EPA rating lists 10.5 hours for a full charge at 18 miles per hour. Standard agency tests do not always run at the absolute peak rate of the vehicle. Real world Level 2 charging hits the full 95.8 kWh capacity in 8.7 hours.
Other vehicles
Charging times derived from EPA data for the 2020 Porsche Taycan Turbo S. Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
