Tesla charging speeds depend on three things: your car's onboard charger (for AC/home charging), your car's battery architecture (for DC fast charging), and the charger itself. This guide lays out the actual numbers for every current Tesla model and trim, using every charger type you're likely to encounter.

AC Home Charging Speeds (Level 1 and Level 2)

Home charging speed is limited by whichever is lower: your car's onboard charger or the charger/outlet's output. Here are the real numbers from Tesla's published data.

Level 1 (120V / NEMA 5-15 — standard household outlet): All Tesla models charge at approximately 2-4 miles of range per hour. The Model 3 gains about 3 mi/hr, the Model Y about 3 mi/hr, the Model S about 3 mi/hr, and the Model X about 2 mi/hr. This is emergency-speed charging — useful for topping up overnight at a hotel, but inadequate for daily home use.

Level 2 (240V / NEMA 14-50 — 32 amps via Mobile Connector): The Model 3 gains approximately 30 mi/hr, the Model Y approximately 29 mi/hr, the Model S approximately 23 mi/hr, and the Model X approximately 20 mi/hr. These speeds apply to Premium and Performance trims. Standard trims with 7.7 kW onboard chargers max out at approximately 20-25 mi/hr on a NEMA 14-50.

Level 2 (240V / Wall Connector — 48 amps): Trims with 11.5 kW onboard chargers reach up to 44 mi/hr on the Wall Connector. This is the maximum home charging speed for any current Tesla. Model S and Model X also support up to 48 amps. Standard trims (7.7 kW onboard charger) will charge at the same rate on a Wall Connector as on a NEMA 14-50 — the onboard charger is the bottleneck.

DC Supercharging Speeds

Supercharging bypasses the onboard charger entirely, pushing DC power directly into the battery. Peak charging speeds vary by model, battery state of charge, temperature, and Supercharger generation.

The Model 3 Premium and Performance trims peak at approximately 250 kW on V3 Superchargers, adding roughly 180 miles in 15 minutes under optimal conditions (battery warm, state of charge below 20%, ambient temperature 60-80°F). The Model 3 Standard RWD peaks lower, at approximately 170-200 kW.

The Model Y Premium and Performance trims also peak at approximately 250 kW, with similar real-world speeds — roughly 160-180 miles in 15 minutes. Standard trims peak around 170-225 kW.

The Model S and Model X peak at approximately 250 kW. The Cybertruck peaks at approximately 250 kW on V3 and supports higher rates on V4 Superchargers where available.

Real-world Supercharging note: Peak speeds only occur in a narrow window (typically 5-20% state of charge with a preconditioned battery). As the battery fills, charging speed tapers — the last 20% (80-100%) takes roughly as long as the first 60% (10-70%). This is why Tesla and most EV experts recommend charging to 80% on road trips and moving on.

What Affects Charging Speed

Battery temperature: Cold batteries charge slowly. Tesla's preconditioning system warms the battery automatically when you navigate to a Supercharger. In winter, this can take 15-30 minutes and makes a dramatic difference — a preconditioned battery may charge twice as fast as a cold one.

State of charge: Charging is fastest when the battery is low (10-30%) and slows progressively as it fills. The charging curve is not linear — don't expect the same kW at 60% that you see at 15%.

Supercharger generation: V3 Superchargers (the most common) deliver up to 250 kW with dedicated power per stall. V2 Superchargers share power between paired stalls — if you park next to an occupied charger, both cars share the available power. V4 Superchargers (newest, still rolling out) support higher peak rates and longer cables.

Ambient temperature: Extreme heat can also trigger thermal throttling, reducing charging speed to protect the battery.

Practical Charging Times

For the scenario most Tesla owners actually care about — how long does it take to go from low battery to road-trip ready:

A 2026 Model Y Premium AWD (327 miles EPA) at a V3 Supercharger: 10% to 80% takes approximately 25-30 minutes, recovering roughly 230 miles. This is a typical Supercharger stop on a road trip.

The same car at home on a Wall Connector (48 amps): 20% to 80% takes approximately 5-6 hours. Start charging when you get home from work, and you're full by bedtime.

On a NEMA 14-50 outlet (32 amps): 20% to 80% takes approximately 7-9 hours. Still comfortable for overnight charging.

Third-Party Charging Options

Tesla vehicles with NACS ports can charge at any NACS-compatible charger, and Tesla includes a J1772 adapter for use at non-Tesla Level 2 stations (which make up the majority of public Level 2 infrastructure). For CCS fast chargers operated by networks like Electrify America, EVgo, or ChargePoint, Tesla owners need a CCS-to-NACS adapter (such as Lectron's 500A adapter). These unlock access to 12,000+ additional CCS fast charging stations across North America.

For home charging alternatives to the Tesla Wall Connector, the Lectron Portable Level 2 Charger delivers 40 amps / 9.6 kW (up to 36 mi/hr) via a NEMA 14-50 plug, with no hardwiring required. At roughly $280, it's a cost-effective option, especially for renters or owners who may move.

The Bottom Line

For daily use, any Level 2 home charging setup handles the job easily. The differences matter most for road trips (where Supercharger peak speed varies by trim) and for Standard trim owners (who should know their 7.7 kW onboard charger limits home charging speed regardless of the charger installed).
