Tesla Wall Connector vs Mobile Connector
As of October 5, 2026, the Tesla Wall Connector sells for $585 and the Mobile Connector for $300 in our verified offers; the Wall Connector delivers up to 11.5 kW (48 A) and the Mobile Connector up to 7.7 kW (32 A) on a NEMA 14-50 outlet, so the Wall Connector charges faster only on a Tesla whose onboard charger accepts more than 7.7 kW.
The two units side by side
| Mobile Connector | Wall Connector | Universal Wall Connector | |
|---|---|---|---|
| Verified price | $300 | $585 | $660 |
| Maximum output | 32 A, 7.7 kW | 48 A, 11.5 kW | 48 A, 11.5 kW |
| On a NEMA 5-15 outlet (120 V) | 12 A, 1.4 kW | Not available | Not available |
| On a NEMA 14-50 outlet (240 V) | 32 A, 7.7 kW | Hardwired | Not published |
| Circuit at full output | 50 A breaker for the 14-50 outlet | 60 A breaker, 4 AWG copper | 60 A breaker, 4 AWG copper |
| Connector | NACS | NACS | NACS + J1772 |
| Cable | 20 ft | 22 ft | 22 ft |
Prices are the verified retailer offers in this database, checked October 5, 2026. The 5-15 figure is the continuous load limit of a 15 A household circuit: NEC 210.20(A) sizes a circuit at 125 percent of a continuous load, so the most a charger may draw from it is 12 A. Breakers are the NEC 240.6(A) standard sizes and copper is the 60 degree C column of NEC 310.16, as on every page of this site.
What each Tesla actually receives
| Vehicle and trim | Car's top charging speed | Mobile Connector, household outlet (5-15) | Mobile Connector, 240 V outlet (14-50) | Wall Connector | Wall Connector adds | Miles per hour, Mobile 14-50 | Miles per hour, Wall Connector |
|---|---|---|---|---|---|---|---|
| Tesla Model Y, Long Range and Performance | 11.5 kW | 1.4 kW | 7.7 kW | 11.5 kW | 3.8 kW | 24 to 32 | 35 to 47 |
| Tesla Model Y, Rear-Wheel Drive and All-Wheel Drive | 7.7 kW | 1.4 kW | 7.7 kW | 7.7 kW | Nothing | 24 to 32 | 24 to 32 |
| Tesla Model 3, Long Range and Performance | 11.5 kW | 1.4 kW | 7.7 kW | 11.5 kW | 3.8 kW | 25 to 32 | 37 to 47 |
| Tesla Model 3, Rear-Wheel Drive | 7.7 kW | 1.4 kW | 7.7 kW | 7.7 kW | Nothing | 25 to 32 | 25 to 32 |
| Tesla Cybertruck, speed table column footnoted to Premium All-Wheel Drive | 11.5 kW | 1.4 kW | 7.7 kW | 11.5 kW | 3.8 kW | 18 to 19 | 27 to 28 |
| Tesla Model X, all trims | 11.5 kW | 1.4 kW | 7.7 kW | 11.5 kW | 3.8 kW | 20 to 24 | 30 to 36 |
Delivered power is the smaller of the charger's output and the car's manufacturer published onboard limit. Miles per hour multiply that power by the EPA range per kWh drawn from the wall for the model years we track, lowest to highest configuration. Tesla's own table, which assumes its own test conditions, lists 30 miles per hour for a Model 3 and 27 for a Model Y on the 14-50 adapter, and 44 for either on a 48 A Wall Connector (Mobile Connector support page, archived March 30, 2025; Wall Connector support page, archived April 2, 2025).
When the Wall Connector's extra speed is usable
If your car is one of these, the Wall Connector adds power over a Mobile Connector on a 14-50 outlet: Tesla Model Y, Long Range and Performance (3.8 kW more); Tesla Model 3, Long Range and Performance (3.8 kW more); Tesla Cybertruck, speed table column footnoted to Premium All-Wheel Drive (3.8 kW more); Tesla Model X, all trims (3.8 kW more).
If your car is one of these, its onboard limit is reached by the Mobile Connector on a 14-50 outlet, and the Wall Connector delivers the same power: Tesla Model Y, Rear-Wheel Drive and All-Wheel Drive; Tesla Model 3, Rear-Wheel Drive.
The difference also shows up as hours. A car that sits plugged in for longer than its full charge time at 7.7 kW finishes by morning on either unit; the gap matters only when the car must refill more energy than 7.7 kW supplies in the hours it is parked.
The NEMA 14-50 circuit
Tesla pairs the Mobile Connector's 14-50 adapter with a 240 volt, 50 A breaker and caps the output at 32 A on it (Tesla support, archived March 30, 2025). On a 50 A breaker the 60 degree C column of NEC 310.16 calls for 6 AWG copper or 4 AWG aluminum. The 125 percent rule alone sets the floor for a 32 A load at a 40 A breaker on 8 AWG copper; the outlet's own 50 A rating is why the larger figure is the one Tesla lists. The Wall Connector at its full 48 A needs a 60 A breaker and 4 AWG copper, and Tesla's table lists lower settings on smaller breakers, down to 12 A on a 15 A breaker.

Tesla charger questions
- Is the Wall Connector faster than the Mobile Connector?
- Only on a Tesla that accepts more than 7.7 kW. The Wall Connector delivers up to 11.5 kW and the Mobile Connector 7.7 kW on a 14-50 outlet. Of the 6 Tesla trims we track, 4 accept more and gain up to 3.8 kW; 2 reach their onboard limit on the Mobile Connector and gain nothing.
- What breaker does a NEMA 14-50 outlet for the Mobile Connector need?
- Tesla pairs the 14-50 adapter with a 50 A breaker at 240 volts and limits the Mobile Connector to 32 A on it. A 50 A breaker takes 6 AWG copper or 4 AWG aluminum under the 60 degree C column of NEC 310.16.
- How much do the Wall Connector and Mobile Connector cost?
- In our verified offers checked October 5, 2026, the Wall Connector is $585 and the Mobile Connector $300; the Universal Wall Connector, which adds a built in J1772 adapter, is $660. Installation is separate.
