Is It Cheaper To Charge a Tesla at Home or With a Supercharger?
It’s much cheaper to charge a Tesla at home unless you have a pre-2017 model.
According to Car and Driver reports, in a year of driving, charging only on Superchargers would double the annual cost of “fueling” up their Teslas, which was estimated to be $2,500 a year.
Americans report spending an average of $3,000 a year on gasoline, according to Value Penguin, so even a year of Supercharging would save a couple of hundred dollars.
Compare that to the fuel costs Car and Driver reported without Supercharging—just over $1,300.
The Difference Between Home Charging and a Tesla Supercharger
The difference between a Tesla Supercharger vs home charger is the power used. Homes supply AC power, so Teslas contain a built-in charger that converts the AC power from the plug into DC that’s stored in the batteries for future use. Superchargers bypass the conversion process by directly sending DC energy.
Superchargers Vs. Destination Chargers
Superchargers and destination chargers are different in speed of charge, user compatibility, and cost of use.
Here’s what you need to know about the Tesla destination charger vs Supercharger:
Superchargers are owned by Tesla, but destination chargers can be sold to businesses that aim to keep electric car owners at the “destination.”
Who can use destination chargers and how much charging will cost depends on the charger’s location, but only Tesla drivers can use a Supercharger.
A destination charger is essentially a Level 2 charger that’s installed so Tesla drivers can charge their cars. A company typically installs a destination charger in the hopes the driver will spend money at their site.
This is the main difference between supercharger and destination charger.
As an added bonus to this article, I’ve created this easy-to-use charging calculator. Simply input your model, charging wattage, and charging percentage, and you will get the estimated time it will take to charge a Tesla in terms of hours. You can play around with numbers a bit just to see how charging time changes:
For example, a restaurant might have a Destination Charger to encourage the driver to stop and buy a meal. The restaurant’s charger will be listed in Tesla’s network of stations. Drivers can use their in-car navigation to locate these chargers for their EV’s and make purchases at the destination.
It’s up to the destination whether they’ll charge the driver. Some provide it as a free service to Tesla drivers, while others only charge non-patrons. Workplaces providing destination chargers are less likely to charge their employees for charging their EVs.
The Destination Chargers are an essential component of the Tesla network. Without them, the Supercharger network would be unable to keep up with demand.
Newer V3 Superchargers Vs. Older V3 Chargers
Tesla claims their V3 Superchargers will dramatically decrease charging time, but many drivers haven’t noticed a significant drop. Still, since V3 chargers don’t power share, your charging speed isn’t affected if another driver uses the same charging station.
Motor Trend tested a new V3 Supercharger to determine if Tesla’s claims the next generation of chargers was faster. They discovered that the V3 did charge more quickly, but the increase didn’t match Tesla’s claims of 50% faster charging time.
This is partially due to battery limitations. Charging a battery too quickly damages the battery. As the battery is charged, incoming electrons have fewer places to go. In addition, the heat generated by this process can damage the battery. Therefore, the charging speed must slow down to protect the battery’s lifespan.
If you would like to find out more about Tesla Supercharging, feel free to give this related article a read. We covered the topic in detail.
However, a full charge isn’t necessary for most drivers. Instead, they charge enough to get to their destination—either home or the next charging station. In just 15 minutes, a V3 Supercharger adds 180 range miles (290 km).
Tesla won’t add signage for a V3 charger, but the Tesla app indicates whether you’re pulling into a V2 or V3, and pricing remains the same. If you have lifetime free charging, Tesla will honor it.
And since Tesla is constantly updating firmware, standard Model 3s vehicles might be able to charge at 250 kW at newer V3 stations by the time you read this.
Charging Tip: A colder batter takes longer to charge. To precondition the batteries to warm up, enter your Supercharger station in advance in your navigation system.

The Difference Between a Level 1 and a Level 2 Charger
The most significant difference between a Level 1 and Level 2 charger is the electricity output. A level 1 charger runs on 110 volts, while a Level 2 runs on 240 volts. The additional voltage means a Level 2 device charges electric vehicles faster.
The default EV charging option is Level 1. It operates with a standard power supply. Each Tesla includes level 1 charging equipment.
All you do is connect your Tesla to a 120-volt regular AC outlet. This is the same outlet you plug most appliances into. If using Level 1 charging, you don’t need to change the wiring in your house.
However, Level 1 is an extremely slow way of charging your vehicle. Typically, they’re powered at 12 or 16 amps and each hour of charging provides around 4 miles (6.43 km) range. Therefore, level 1 is the slowest charging option, commonly called “trickle charging.”
An overnight, eight-hour charge will get around 32 miles (51.4 km) range, depending on weather and other variables. If your commute is 15 miles (24 km) or less one way, an overnight charge will get you to work and back (with a grocery stop along the way).
But drivers typically charge up a long time over the weekend or head out to a Destination or Supercharger during the week, so the trickle charging is enough for most Tesla owners.
Charging Level 2 is much speedier than Level 1. For example, an hour of charging provides a 14 to 35 miles (22.5 to 56.3 km) range. Although it seems like you should opt for Level 2, consider the following:
- Installation costs can be steep, often a thousand dollars or more.
- The charger itself isn’t free.
- An overnight charge provides plenty of range for around town and work trips.
- Your workplace might provide a charger.
Whether you opt for a Level 2 charger will depend on your budget and whether your driving habits necessitate it.
Home Charging Station for a Tesla
You may need a home charging station for an EV if you drive longer commutes. Shorter commutes and the availability of Superchargers may significantly negate the need for a charging station. You must also factor in whether you want or can upgrade to a 240-volt outlet.
If you plan to stick with Level 1, you do not need to buy a connector since they’re standard with all vehicles. The bundle includes the conductor, an adapter to plug into an outlet, and an adapter to plug into public charging stations.
Tesla encourages the purchase of a wall connector, but the advantage of a mobile connector is you can take it with you if you move.
Tesla touts several reasons to upgrade to a Level 2 Wall Connector:
- Speed. Tesla claims charging speed can increase range up to 2 times, depending on the breaker amperage.
- Convenience. A Wall Connector can be linked to a home Wi-Fi network, enabling firmware updates, remote diagnostics, and control over which cars hooked up to the connector should be charged. In addition, up to 4 Wall Connectors can be linked from one circuit, which is excellent for people who have more than one Tesla.
- Indoor or Outdoor. The Wall Connectors are designed so they can be mounted outdoors without damaging the connector or vehicle.
Remember, however, you’ll need an electrician to add the connector to your wiring, as the electrical panel might not be able to handle a 50- or 60-amp breaker. Do not try to upgrade your power yourself.

Can I Install a Tesla Supercharger at My Home?
You can’t install a Tesla Supercharger at home, mostly because Tesla won’t sell them. Still, even if they were available for purchase, the financial downsides and installation process would likely deter you from doing so.
Even if you could convince Tesla to sell you a Supercharger, the cost would be prohibitive. According to Electrek, a business owner in Sweden convinced Tesla to sell him a Supercharger due to the poor supercharger coverage in the region. Electrek estimated he paid a little less than the price of a new Model S. Which would you want—a Supercharger or a new Tesla?
Another hurdle to jump would be installation. You may live in a county or city that doesn’t allow homeowners to install the electricity requirements for a Level 3 charger. Even if the jurisdiction does allow the installation of a 480-volt charger, the extra installation costs would be over $10,000 at a minimum. You could add a hell of a lot of Tesla accessories to your EV with that kind of money!
Finally, and most important, regular charging of a Tesla with Superchargers will degrade the batteries to the point they won’t be able to hold their charge as long. The battery management system of electric vehicles limits charging speed if the vehicle is charged too frequently at Superchargers.
Luckily for Tesla owners, most use a combination of at-home and occasional Supercharging.
How Much Does Your Electricity Bill Go Up With a Tesla?
How much your electricity bill goes up with a Tesla is negated by the costs saved in gasoline. For instance, the average American spends around $250 a month on gasoline, and an increase of $50 a month on your bill because of a Tesla means savings of $200 a month by no longer paying for gasoline.
The estimates for how much you can potentially save vary from source to source. For example, Forbes estimated a 2020 Tesla Model 3 to have annual fuel costs of $500 while costs for a 2020 Honda Accord hover around $1,050. And Solar Reviews estimates that gasoline in a typical car comes out to $1,117 per year, while a Tesla would cost $485.
Home Charging: The Convenience of Charging at Home
Owning a Tesla vehicle comes with a lot of perks, and one of the best things is the option to charge your car at home. With a home charger, EV drivers can charge their Tesla cars overnight or whenever it’s convenient for them, without having to worry about idle fees or finding a charging station.
This is especially useful for those who take short trips around urban areas in their EV or for those who want to avoid the high energy costs associated with charging at public stations.
Cost Savings: Why Charging at Home is Cheaper
Compared to public charging options, home charging is a cost-effective solution for EV drivers.
With a home charger, you can charge your EV at a slower charging speed, which can lower your electricity costs.
According to the U.S. Energy Information Administration, the average cost of electricity in the United States is 13 cents per kWh, which means that charging a Tesla Model Y Long Range with a full battery capacity of 75 kWh would cost less than $10.
Additionally, some property managers and property owners offer free or reduced-cost electricity for EV charging, further reducing the costs for electric vehicle owners.
Going Green: The Environmental Benefits of Home Charging
Home charging also has the added benefit of being more environmentally friendly. By using a home charger, EV drivers can charge their Tesla cars using renewable energy sources such as solar panels. This not only reduces the carbon footprint associated with charging at public stations, but it also helps to support the growth of clean energy.
It’s important to note that if you’re planning on taking a road trip or a longer trip, you’ll need to plan for charging at a Tesla Supercharger station. With the Tesla Supercharger network expanding rapidly across North America, these charging stations are becoming more and more accessible, and they offer much faster charge rates than home charging. With the Model S Long Range and Model X Long Range, you can get up to 170 miles of charge in just 30 minutes.
Overall, home charging is a great option for those who primarily drive around urban areas and for those who want to save money on energy costs.
However, for longer trips or road trips, the Tesla Supercharger network is the best option for quickly charging your car’s battery.
