What EV Charger Do You Need for a 2020 Porsche Taycan 4S Perf Battery?
Your home panel can push massive power, but the car dictates what goes into the battery. This Porsche draws a maximum of 48 amps on Level 2 equipment. Feeding it anything larger will not speed up the refill.
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 9.0 hours |
| Range added per hour (Level 2) | about 23 miles |
| Full charge on a 120 V outlet | about 69 hours |
| Range added per hour (120 V) | about 3.0 miles |
| EPA rated range | 203 miles |
| Energy for a full charge | about 99.1 kWh at the wall |
Why 48 amps and not more
The onboard charger maxes out at 48 amps and 11.0 kilowatts. Buying a bigger 80 amp charger is a waste of money because the car cannot draw the extra current. At 48 amps, you replenish the 99.1 kWh battery in 9.0 hours. You get 23 miles of range for every hour plugged in. The EPA test measures a slightly slower 10.5 hours because that test cycle accounts for grid efficiency losses.
What the install involves
You need a dedicated 60 amp breaker to feed this setup safely. The supply line must be hardwired directly into the charger because no household receptacle handles 48 continuous amps. Call an electrician to pull the wire and land the conductors on the breaker. They must verify your main panel has spare capacity for a heavy continuous load before starting.
Chargers that match this car
Energy monitoring built in. Hardwire it for the full 48 A.
Compact unit, good for tight garages.
Adjustable from 16 A to 50 A in the app, which helps if your panel is tight.

Common questions
- Can I plug this car into a standard wall outlet?
- You can plug it into a standard 120 volt outlet using Level 1 charging, but it takes 69 hours to fill the battery from empty. That delivers 3.0 miles of range per hour. You will want a Level 2 setup for daily driving.
- What connector does the car use?
- This vehicle uses a J1772 connector for standard AC Level 2 charging. Every non-Tesla EV sold in North America through 2024 uses this plug format. You can also use adapters to access Tesla destination equipment.
- Why does the EPA charge time differ from the max rate?
- The EPA rated charge time is 10.5 hours at 19 miles per hour. The theoretical maximum rate fills the car in 9.0 hours at 23 miles per hour. Standard testing accounts for charging losses that happen in the real world.
- Should I buy a 50 amp or 48 amp charger?
- Buy a unit that matches your car limit of 48 amps. Units like the ChargePoint Home Flex can be dialed down in the app if your panel has tight capacity. Match the breaker size to the output you configure.
