Frequently Asked Questions

On a standard Wall Connector, it typically takes 6-10 hours for a full charge. A standard 120V outlet is much slower, adding about 3 miles of range per hour.
Supercharging costs vary by location and time of day, but typically range from $0.25 to $0.50 per kWh. A 10-80% charge usually costs $15-$25.
For daily use, Tesla recommends charging to 80% or 90% for Lithium-ion batteries. LFP batteries (found in some Model 3 RWD) can be charged to 100% regularly.
Yes, cold batteries charge slower. Using the in-car navigation to a Supercharger will 'precondition' the battery to ensure the fastest possible charge.
V2 Superchargers provide up to 150kW and share power between stalls. V3 Superchargers provide up to 250kW and do not share power, allowing for faster speeds.
At a V3 Supercharger, you can add 150-200 miles in 15 minutes. A standard home Level 2 charger adds about 30-44 miles of range per hour.
