How Fast Will Your Tesla Charge? Range per Hour Based on Outlets & Amps

When it comes to charging your Tesla, knowing what kind of outlet you have and how many amps it can deliver is key to figuring out how quickly you’ll add miles to your battery. Different outlets can provide vastly different charging speeds, and with the second-generation Tesla Mobile Connector maxing out at 32 amps, you’ll want to match the right adapter to your outlet for the best results.

Below, we’ll explore some common outlet types, their amperage ratings, and the approximate miles of range per hour (RPH) you can expect for various Tesla models—Model X, Model S, and Model 3—based on AC WORKS® charging adapters. These figures are based on optimal conditions; actual results may vary depending on temperature, battery state of charge, and other factors.

1. High-Power Outlets (240V, 50A-60A)

• 14-60 - 240V 60A OR 14-50, CS6365, 10-50, 6-50 | ALL 240V 50A

  • Model X: ~25 miles/hour
  • Model S: ~29 miles/hour
  • Model 3: ~30 miles/hour

Why choose these outlets?
These high-amperage outlets are typically used for larger appliances (like electric ranges or welders) or in RV and generator connections. They’re an ideal choice if you want some of the fastest home-charging speeds possible with the Tesla Mobile Connector setup.

2. Mid-Range Outlets (240V, 30A)

• 6-30, 14-30, 10-30, L14-30 (All 240V 30A)
  • Model X: ~15 miles/hour
  • Model S: ~17 miles/hour
  • Model 3: ~23 miles/hour

Why choose these outlets?
These are commonly found in households for dryers, air conditioners, or certain power tools. They supply 240V at 30A, which offers a solid charging rate—though not as quick as the 50A–60A range. However, they’re easier to find and install in many residential setups.

3. Specialty 20A and 15A Outlets (240V)

• L6-20, 6-20 (240V 20A) + 6-15 (240V 15A)

  • Model X: 8~10 miles/hour
  • Model S: 9~12 miles/hour
  • Model 3: 11~15 miles/hour

Why choose these outlets?
These are lower-power 240V connections and are often used for some specialized equipment. They’re not as common in residential settings, but if you have one already installed, it can still provide a notable bump in charging speed compared to a standard 120V outlet.

4. 120V Outlets (30A, 20A, and 15A)

• 5-30, TT-30, L5-30 (120V 30A)

  • Model X: ~7 miles/hour
  • Model S: ~8 miles/hour
  • Model 3: ~10 miles/hour

• 5-15 (120V 15A) OR 5-20 (120V 20A) 

  • Model X: 4~5 miles/hour
  • Model S: 4~5 miles/hour
  • Model 3: 5~7 miles/hour

Why choose these outlets?
Standard 120V outlets are the most common in North America but provide the slowest charging speeds. Still, they’re incredibly handy for “emergency” or overnight top-ups if you have no other option available.

5. The Role of the Second-Generation Mobile Connector

Keep in mind that Tesla’s OEM second-generation Mobile Connector is limited to 32 amps max output. Even if you have a 60A or 50A outlet available, the Mobile Connector will only draw 32 amps, capping your charging speed. Many owners find this sufficient for overnight charging—particularly if you arrive home with plenty of remaining range. For faster speeds above 32 amps, you’ll need to consider a dedicated Tesla Wall Connector or other high-power EVSE (Electric Vehicle Supply Equipment).

6. Practical Tips for Home Charging

1. Match the Adapter to Your Outlet
   AC WORKS® offers a wide range of adapters. Make sure you’re using the one specifically designed for your outlet’s configuration to ensure safety and compatibility.

2. Install Higher Amp Circuits (Where Possible)
   If you have the option to upgrade your garage or parking area with a 240V 50A circuit, you’ll see a significant boost in charging speed compared to lower-amperage circuits.

3. Monitor Charging Sessions
   Use your Tesla app to keep track of charging progress. You’ll see how many miles of range you’re gaining per hour, and you can ensure everything is functioning properly.

4. Charge Overnight
   Overnight charging is convenient and can often take advantage of off-peak electricity rates. Even slower 120V outlets can provide enough range to get around town the next day if you have ample hours to charge.

5. Consider a Permanent EV Charging Solution
   If you rely on your Tesla as a daily driver and rack up miles, installing a dedicated Level 2 EV charger or a Tesla Wall Connector could be worth the investment for faster, more consistent charging.

7. Conclusion

Charging speed may vary, but understanding the power of the outlet you’re using will give you a clear idea of the miles you can gain per hour. Whether it’s a 240V high-amperage outlet that nets you around 25–30 miles per hour, or a basic 120V 15A plug that’s just enough to get you by, being informed helps you plan your daily and long-distance driving.

If you’re looking to maximize charging convenience, check out the range of AC WORKS® adapters. They’re designed to help you safely connect your Tesla to a variety of outlets, whether you’re at home, on the road, or visiting a friend’s workshop.
