Reference
Charger types.
Level 1 · 120V
Standard household outlet. Slowest but most accessible option. ~3–5 miles of range per hour.
Level 2 · 240V
Tesla Wall Connector at 48 A delivers 11.5 kW, about 30–44 miles of range per hour. A Mobile Connector on a NEMA 14-50 outlet delivers 7.7 kW.
Supercharger V2
Up to 150 kW. Plan on 30–40 minutes for 20–80% on Model 3 and Model Y.
Supercharger V3 / V4
Up to 250 kW for Model 3 and Model Y on both V3 and V4 posts. Plan on 20–30 minutes for 20–80%; the rate peaks early and tapers as the pack fills.
FAQ
Charging questions.
How long does it take to charge a Tesla at home?
On a Level 2 Wall Connector at 48 amps (11.5 kW), a Model 3 or Model Y goes from 20% to 80% in roughly four hours and adds about 30–44 miles of range per hour. On a standard 120V outlet the same charge takes well over a day, adding 3–5 miles per hour, which is enough for short commutes but not much else.
How long does a Supercharger take?
A Model 3 or Model Y typically goes from 20% to 80% in 20–30 minutes on a V3 or V4 Supercharger. The car peaks at up to 250 kW for a few minutes near the bottom of the pack and tapers steadily from there, so the last 20% takes nearly as long as the first 60%. Cybertruck, with its larger pack, takes a little longer.
Why does charging slow down after 80%?
To protect the battery. The car's management system reduces the charge rate as cells approach full, on every charger type. For road trips it is faster to leave at 80% and stop again than to wait for 100%.
How much does it cost to charge a Tesla?
At home, a full 20–80% charge on a Model 3 Standard costs about $5–6 at the US average of $0.14 per kWh, and roughly half that on an off-peak EV rate. At a Supercharger the same session runs $15–25 depending on the site's per-kWh price and time of day, which the Tesla app shows before you plug in.
