Best Home Charger for the Tesla Model 3
By LarryLeo · Updated October 4, 2026 · Based on manufacturer specs, not hands-on testing
Short answer
A NACS wall charger set to 40–48 amps; base trims may only use about 32 amps.
| Charge port | NACS (Tesla) port |
|---|---|
| Onboard AC charger | About 7.6–11.5 kW AC depending on trim (32–48 amps) |
What to look for
- Base trims have a smaller onboard charger, so a 48-amp unit won't charge them faster than 32 amps.
- A NACS-plug charger means no daily adapter.
- Overnight on 32 amps still adds well over 150 miles for most drivers.
