How Many Amps Should I Charge My Tesla At Home?

The optimal amperage for charging your Tesla at home depends on several factors, including the type of charger you have, the power capacity of your home’s electrical system, and your desired charging speed.

Types of Tesla Chargers

Tesla offers two types of chargers for home use:

– Wall Connector: A permanent charging station mounted on a wall. It requires professional installation and can charge at up to 48 amps (11.5 kW).
– Mobile Connector: A portable charger that plugs into a standard 120V or 240V outlet. It charges at up to 32 amps (7.7 kW).

Electrical System Capacity

Your home’s electrical system must be able to handle the amperage required for Tesla charging. Most homes have a 100-amp or 200-amp electrical panel, which can typically support charging at 32 amps or 48 amps, respectively. However, it’s important to consult with a qualified electrician to verify the specific capacity of your system.

Charging Speed

The amperage you choose will affect the charging speed. Higher amperage results in faster charging. The following table summarizes the charging speeds for different amperages:

AmperageCharging Speed (hours)
16 Amps10-12 hours
32 Amps5-6 hours
48 Amps3-4 hours

Recommended Amperage

Based on the factors discussed above, the recommended amperage for charging your Tesla at home is:

– For a Wall Connector: 48 amps (11.5 kW)
– For a Mobile Connector on a 120V outlet: 12 amps (1.4 kW)
– For a Mobile Connector on a 240V outlet: 32 amps (7.7 kW)

Additional Information

  • Maximum Amperage: The maximum amperage for Tesla charging is 48 amps. Exceeding this amperage can damage the charger and/or your vehicle.
  • Electrical Safety: Always ensure that the charger and electrical system are properly installed and maintained to prevent electrical hazards.
  • Charging Time: The actual charging time will vary depending on the battery size of your Tesla and the level of charge.
  • Power Consumption: Tesla charging consumes a significant amount of electricity. Monitor your energy usage to avoid surprises on your electric bill.
  • Charging Costs: The cost of charging your Tesla will vary depending on your local electricity rates. Consider using off-peak charging hours to save money.

Interesting Facts

  • Tesla chargers are designed to adjust the amperage automatically based on the available power from the electrical system.
  • The Tesla Wall Connector can be equipped with a Power Sharing feature, which allows multiple vehicles to share the same electrical circuit.
  • Tesla offers a mobile app that allows you to monitor and control the charging process remotely.
  • Tesla vehicles can precondition their batteries during charging to improve efficiency and range.
  • Tesla is constantly developing and improving its charging technology, including new charging stations and faster charging rates.


1. Can I charge my Tesla using a dryer outlet?

Yes, but it’s not recommended. Dryer outlets typically provide 30 amps, which could overload your home’s electrical system if other appliances are also running.

2. What happens if I plug my Tesla into a higher amperage outlet than recommended?

The Tesla charger will automatically adjust the amperage to the maximum safe level. However, charging at a higher amperage may result in faster degradation of the battery.

3. Can I charge my Tesla overnight?

Yes, you can charge your Tesla overnight using a timer or the Tesla mobile app to set a charging schedule.

4. How much does it cost to charge a Tesla at home?

The cost will vary depending on your local electricity rates and the size of your Tesla’s battery. On average, it costs around $10-$20 to fully charge a Tesla at home.

5. Can I use a public charging station instead of charging at home?

Yes, you can use public charging stations, but they are typically more expensive than charging at home. Additionally, public charging stations may require payment or subscription fees.
