Charging time depends on which charger you use and your car's battery size
A Tesla takes between 20 minutes and 10 hours to charge, depending on whether you use a Supercharger, a public Level 2 charger, or a home charger. A Supercharger adds 200 miles of range in about 20 to 30 minutes. A Level 2 charger at home or a public station takes 4 to 10 hours for a full charge. A standard 120-volt household outlet charges so slowly — roughly 2 to 3 miles of range per hour — that most owners treat it as an emergency-only option.
The actual time for your car depends on three things: which Tesla model you own, how empty the battery is, and the charger's power output. A Model 3 charges faster than a Model X because it has a smaller battery. Charging from 10 percent to 80 percent is also much faster than charging from 80 percent to 100 percent, because the battery slows down as it fills to protect itself.
Key Takeaways
- Superchargers add 200 miles in 20 to 30 minutes but are designed for road trips, not daily charging.
- Home charging with a Wall Connector takes 8 to 10 hours for a full charge and is the cheapest and most convenient option for daily use.
- Public Level 2 chargers take 4 to 10 hours depending on the charger's power and your car's battery size.
- Charging from 80 to 100 percent takes much longer than charging from 0 to 80 percent because the battery intentionally slows down near full capacity.
Home charging with a Wall Connector
A Tesla Wall Connector installed at home is the most practical option for daily charging. It delivers 11.5 kilowatts of power and charges a Model 3 from empty to full in about 8 to 10 hours. A Model Y takes roughly the same time. A Model S or Model X, which have larger batteries, takes 10 to 12 hours.
You can also use a standard 120-volt household outlet, but this is impractical for regular use. It adds only 2 to 3 miles of range per hour, so charging a Model 3 from empty would take 40 to 50 hours. Most owners use a standard outlet only when traveling or in emergencies.
The cost to install a Wall Connector ranges from $500 to $2,000 depending on your home's electrical panel and how far the charger is from it. Once installed, charging costs roughly $0.03 to $0.05 per mile, depending on your local electricity rates. This is significantly cheaper than gasoline.
Superchargers for road trips
Tesla Superchargers are the fastest option and are designed for long-distance travel. They deliver 150 to 250 kilowatts of power and add about 200 miles of range in 20 to 30 minutes. Charging from 10 percent to 80 percent takes roughly 25 minutes. Charging from 80 to 100 percent takes an additional 15 to 20 minutes because the charger deliberately slows down to protect the battery.
Superchargers are located along highways and in cities. You can find them using the Tesla navigation system, which automatically routes you through Superchargers on long trips and tells you how long you'll wait. During peak hours, you may wait 10 to 20 minutes for a charger to become available.
Supercharging costs between $0.25 and $0.50 per kilowatt-hour depending on location and time of day. A full charge typically costs $15 to $25. Some owners with older Tesla models have unlimited free Supercharging, but most pay per use.
Public Level 2 chargers
Public Level 2 chargers are found at shopping centers, parking garages, hotels, and workplaces. They deliver 7 to 19.2 kilowatts of power and charge a Model 3 from empty to full in 4 to 10 hours, depending on the charger's power output. A Model Y takes roughly 6 to 12 hours.
Many public Level 2 chargers are free, though some charge between $1 and $3 per hour or $0.20 to $0.30 per kilowatt-hour. Apps like PlugShare and A Better Route Planner show you where public chargers are located, their power output, and whether they're currently available.
Public Level 2 chargers are useful if you're parked for several hours — at work, at a restaurant, or overnight at a hotel. They're not practical for quick top-ups because the charging speed is much slower than a Supercharger.
How battery size affects charging time
Different Tesla models have different battery sizes, which changes how long charging takes. A Model 3 Standard Range has a 50 kilowatt-hour battery, while a Model 3 Long Range has a 75 kilowatt-hour battery. A Model S Long Range has a 100 kilowatt-hour battery.
A larger battery takes longer to charge at any given charger. A Model 3 Standard Range charges from empty to full in about 6 hours on a home Wall Connector, while a Model S Long Range takes about 12 hours on the same charger. The difference is the battery size, not the car itself.
You can check your Tesla's battery size in the car's settings under "Service" or in the Tesla app. Knowing your battery size helps you estimate how long charging will take at any charger.
Why charging slows down as the battery fills
All Tesla chargers slow down automatically as the battery approaches full capacity. Charging from 0 to 80 percent is fast because the battery can accept power quickly. Charging from 80 to 100 percent is much slower because the battery deliberately reduces power intake to protect itself and extend its lifespan.
This is why most owners don't charge to 100 percent every day. Charging to 80 percent takes about 80 percent of the time it would take to reach 100 percent, but it's better for long-term battery health. For daily driving, Tesla recommends charging to 80 percent and only charging to 100 percent before a long trip.
On a Supercharger, this slowdown is very noticeable. The first 20 minutes gets you to 80 percent, but the next 15 to 20 minutes only gets you from 80 to 100 percent. Many road-trippers stop at 80 percent and leave, since the extra 20 miles takes a disproportionate amount of time.
Charging time comparison table
| Charger Type | Power Output | Time to Full Charge (Model 3) | Time to 80 Percent (Model 3) |
|---|---|---|---|
| 120-volt household outlet | 1.4 kW | 40–50 hours | 32–40 hours |
| Home Wall Connector | 11.5 kW | 8–10 hours | 6–8 hours |
| Public Level 2 charger | 7–19.2 kW | 4–10 hours | 3–8 hours |
| Tesla Supercharger | 150–250 kW | 25–30 minutes | 20–25 minutes |
Frequently Asked Questions
Can I charge a Tesla overnight at home?
Yes. A Wall Connector charges a Model 3 from empty to full in 8 to 10 hours, so plugging in before bed and unplugging in the morning works well for daily driving. Most owners leave their car plugged in every night and wake up with a full charge.
How long does a Supercharger stop take on a road trip?
Plan for 25 to 30 minutes to charge from 10 to 80 percent, plus any wait time for a charger to become available. On busy highways during peak travel times, you might wait 10 to 20 minutes. Most owners use this time to eat, use the restroom, or stretch.
Is it bad to charge a Tesla to 100 percent every day?
Tesla recommends charging to 80 percent for daily use to extend battery lifespan. Charging to 100 percent every day causes slightly faster degradation over years, but the difference is small. Charge to 100 percent only before long trips.
What's the cheapest way to charge a Tesla?
Home charging with a Wall Connector is the cheapest option, costing roughly $0.03 to $0.05 per mile depending on your local electricity rates. Supercharging costs $0.25 to $0.50 per kilowatt-hour, making it 5 to 10 times more expensive per mile.
Do all Teslas charge at the same speed?
No. Smaller models like the Model 3 charge faster than larger models like the Model S or Model X because they have smaller batteries. Newer Teslas also charge slightly faster than older ones due to hardware improvements, though the difference is minor.
