What EV Charger Do You Need for a 2019 Tesla Model S 100D?
You need a 48 amp Level 2 home charging setup for the 2019 Tesla Model S 100D. The internal onboard charger sets this limit. It cannot draw power any faster.
The numbers
| Maximum AC charging rate | 11.5 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 | NACS |
| Full charge on Level 2 | about 9.7 hours |
| Range added per hour (Level 2) | about 35 miles |
| Full charge on a 120 V outlet | about 77 hours |
| Range added per hour (120 V) | about 4.3 miles |
| EPA rated range | 335 miles |
| Energy for a full charge | about 111.2 kWh at the wall |
Why 48 amps and not more
The car accepts a maximum of 48 amps, so buying a larger charger wastes money. A 48 amp EVSE replenishes 35 miles of range every hour. You get a full battery in 9.7 hours from empty. Feeding this car with a smaller 32 amp unit slows down your daily turnover time. Pumping more than 48 amps into the vehicle achieves nothing because the onboard hardware caps the intake.
What the install involves
You must install a 60 amp breaker to feed this equipment safely. The wiring requires a hardwired connection because no standard wall receptacle handles 48 continuous amps. Hire a licensed electrician for this job. They will run heavy gauge copper wire from your electrical panel to the mounting location.
Chargers that match this car
Your car has a NACS port. The NACS units below plug straight in; any J1772 unit works with the adapter supplied with the car.
Native NACS plug, no adapter needed.
Dual plug: works with NACS and J1772 cars.
Tesla's own unit. Native NACS, hardwire only.

Common questions
- Can I plug this car into a standard wall outlet?
- Level 1 charging from a standard household outlet delivers 4.3 miles of range per hour. A full recharge takes 77 hours, which is too slow for daily driving.
- What connector does the car use?
- Your car uses the NACS connector natively. A J1772 adapter ships with the vehicle so you can plug into third party Level 2 units.
- Why does the EPA charge time show 12 hours?
- The EPA test protocol uses different parameters and does not always reflect the peak AC rate of the vehicle. Your actual maximum rate restores 35 miles of range per hour.
- Which charger should I buy?
- The Tesla Wall Connector matches your car natively and supports the full 48 amp draw. It requires a hardwired installation.
