Tesla Model S home charger: charge time and which amps it can use

Tesla Model S home charger buying guide: chargers matched to it

The Tesla Model S takes at most 11.5 kW from a home charger, which it reaches at 48 A. The lowest verified price for a charger that fits its charge port and reaches that rate is $199.00, for the MUSTART Level 2 Tesla EV Charger, 16/25/32/40/48 A adjustable (23 ft cord): 48 A, hardwired. No plug-in charger we track reaches it: on an outlet a charger may draw at most 80 percent of the outlet's rating, and the fastest plug-in option delivers 9.6 kW (11.6 to 11.8 h to full), from $179.00 for the MUSTART Tesla Portable (NACS). A higher-rated charger charges it no faster: the car caps the rate at 11.5 kW, so each of the 8 matching chargers rated above 48 A (from $479.00) delivers the same 11.5 kW at its rating as the MUSTART Level 2 Tesla EV Charger, 16/25/32/40/48 A adjustable (23 ft cord) at $199.00. Spending less buys a slower charge: the MUSTART Level 1 & 2 Tesla EV Charger, 16 A (NEMA 5-15 and 6-20 plugs, 25 ft cord), 16 A at $109.00, takes 29.0 to 29.5 h to fill it against 9.7 to 9.8 h.

Prices were verified at the named seller on the date the charger's own page shows, all on or after October 26, 2026. Rate and full charge use the 11.5 kW onboard limit and the EPA wall energy for a full charge (111 to 113 kWh).

Charge time by charger amps

A charger's amp rating sets its power on a 240 volt circuit; the car then takes the smaller of that and its own onboard limit. Each row is one standard charger rating.

Power is amps times 240 volts. Full-charge times divide the EPA wall energy for a full charge (111 to 113 kWh), which already includes charging losses, by the rate the car accepts. The comparison column reads the car's limit. The last column counts chargers in this database rated at exactly that current that plug into this car directly.

How these Level 2 times compare with a standard 120 volt outlet, in hours to full and miles added overnight for every vehicle family, is in Level 1 vs Level 2 charging compared by vehicle.

For charge time and cost on a 120 V outlet, the Mobile Connector or the Wall Connector, from 10 to 80 or 20 to 100 percent, use the Tesla charging calculator.

Charging the Tesla Model S on a regular 120 volt outlet

A standard household outlet is Level 1 charging. On a 15 A household circuit it can supply 12 A for hours at a time, which is 1.44 kW: far below the car's 11.5 kW limit, so the outlet, not the car, sets the speed.

The 120 V figures divide the EPA wall energy for a full charge (111 to 113 kWh) by 1.44 kW, and multiply 1.44 kW by the EPA range per wall kWh of the lowest and highest configuration, the same arithmetic as the Level 2 table above. EPA measures that energy on a Level 2 charger; the same wall energy is assumed on Level 1. The 15 A circuit's 12 A ceiling is the NEC 125 percent continuous-load rule (210.20(A)). No maker page we could verify states which charging cord, if any, ships with this car, so none is stated.

Tesla Model S charge port by model year

The port is the one a home charger plugs into. A year with two rows has a trim or build split. An adapter covers either direction.

What a full charge costs

Electricity is the whole running cost, and it is the number that varies most by where you live. A full 111 to 113 kWh at the Tesla Model S, priced three ways:

Rates are the EIA residential series, August 2026. Your own utility and any time-of-use plan decide the real figure.

The circuit this car needs

A home charger is a continuous load, so the National Electrical Code sizes both the breaker and the conductor at 125 percent of its draw. A charger matched to this car's 11.5 kW ceiling pulls 48 amps at 240 volts, which needs a 60 amp circuit rather than the 48 amp one the arithmetic alone suggests. That gap is where most installation quotes go wrong.

Of the 60 chargers that plug in directly here, 25 meet or beat the car's ceiling. Going above it changes nothing for this vehicle, though it leaves headroom for a future one that draws more.
