Tesla Charging Time Calculator: How Long to Charge
This Tesla charging time calculator estimates how long it takes to charge a Model 3, Model Y, Model S, Model X or Cybertruck, from a standard wall outlet to a Tesla Wall Connector to a Supercharger. Pick your model, your charger and the battery window you want to fill. It accounts for each Tesla’s onboard AC charger limit and the way DC fast charging slows as the battery fills. For the cost of that charge at home, see the Tesla home charging cost calculator.
On a Tesla Wall Connector at home (11.5 kW), a Tesla Model Y Premium RWD charges from empty to full in about 7h 32m, which is a normal overnight. A Supercharger does the busy part, 10 to 80 percent, in about 26 minutes. A regular 120 volt wall outlet adds only about 5 miles of range per hour, so it is a top-up, not a real charge. Charging is fast at a low battery and slows a lot above 80 percent, which is why road trip charging stops at 80. Set your model and charger below for your own number.

Why Charging Time Varies So Much
The same Tesla can take 20 minutes or two days to charge depending on where it is plugged in. Four things decide it: the charger’s power, the car’s onboard limit, whether it is AC or DC, and how full the battery already is.
Charger power comes first
A 120 volt wall outlet delivers about 1.3 kW. A 240 volt Level 2 charger runs 7.7 to 11.5 kW. A V3 or V4 Supercharger delivers up to 250 kW of DC power. That range is why the same charge can take all night or a coffee break.
The onboard AC limit
On any home or Level 2 charger, the car’s onboard charger sets the ceiling. Most Teslas cap at 11.5 kW (48 amps), so a bigger home charger will not charge them faster. The Model 3 RWD is limited to 7.7 kW.
Superchargers and the taper
DC fast charging bypasses the onboard charger, up to 250 kW on most Teslas and 325 kW on the Cybertruck. That peak only holds at a low battery. As the pack fills, the car slows the power to protect the cells.
Battery size and where you start
A bigger battery takes longer to fill, and the last 20 percent can take as long as the first 60. That is why road trip planners target 10 to 80 percent on a Supercharger.
How the Charging Time Is Calculated
The tool starts with the energy your battery window needs, then divides by the real power the car can accept, which is different for AC and DC charging.
Energy needed = usable battery × (end % minus start %)
Time = energy needed ÷ real charging power
At home, the real power is the lower of the charger and the car’s onboard limit, minus about 10 percent conversion loss. For DC fast charging, the tool uses close to peak power at a low battery and steps it down as the pack fills, so a 10 to 80 percent stop lands near real world times instead of the unrealistic figure you get from dividing by peak power. Real times run longer in cold weather or when a Supercharger is shared. For any other brand, use the EV charge time calculator.

Charging a Tesla at Home
For most owners, home is where nearly all charging happens. The equipment you use sets the speed.
The fastest home option is the Tesla Wall Connector, a hardwired Level 2 unit that delivers up to 11.5 kW on a 60 amp circuit, about 46 miles of range an hour for a Tesla Model Y Premium RWD. The Mobile Connector on a 240 volt NEMA 14-50 outlet draws up to 32 amps, or 7.7 kW, which still refills most packs overnight. On an ordinary 120 volt outlet it trickles in about 5 miles an hour, fine for a plug-in hybrid but slow as a Tesla’s only source. All 2026 Teslas use the NACS port.

Tesla Charging Time Questions, Answered
On a Tesla Wall Connector at 11.5 kW, a Tesla Model Y Premium RWD charges from empty to full in about 7h 32m, a normal overnight. A Model S or Model X takes about 9h 11m and a Cybertruck about 11h 53m. On a 7.7 kW Mobile Connector, add a few hours. Since most people plug in nightly and only top up, the practical daily charge is far shorter.
A 10 to 80 percent charge takes about 26 minutes for a Tesla Model Y Premium RWD at a V3 or V4 Supercharger, and about 44 minutes at an older 150 kW V2. Charging past 80 percent takes much longer and is usually skipped on a trip.
A standard 120 volt outlet adds only about 5 miles of range per hour, so a full charge of a Tesla Model Y Premium RWD takes about 66h 40m. It is fine as an occasional top-up or for very low daily mileage, but a 240 volt setup is the better main source.
On an 11.5 kW Wall Connector, a Tesla Model Y Premium RWD adds about 46 miles of range per hour. A 7.7 kW Mobile Connector adds about 31, and a 120 volt outlet about 5. Efficient cars gain more miles per hour than heavy ones on the same charger.
To protect the battery, the car reduces charging power as the pack fills. It accepts near full power at a low state of charge and much less near the top, so the last 20 percent can take as long as the first 60. On road trips it is faster to stop at 80 percent and drive on.
Only up to the car’s onboard AC limit. Most Teslas cap AC charging at 11.5 kW, and the Model 3 RWD at 7.7 kW, so a charger rated higher will not charge them faster. To go faster you need a Supercharger, which bypasses the onboard charger.
Its 123 kWh battery is the largest in the lineup. On a Wall Connector a full charge takes about 11h 53m. On a V4 Supercharger it can pull up to 325 kW and does 10 to 80 percent in about 32 minutes.
Yes. A cold battery cannot accept full power, so charging is slower until the pack warms up, sometimes at half speed or less on a Supercharger. Routing to the charger in the car’s navigation preconditions the battery on the way.
