The drive from the heart of San Antonio to the charming, German-influenced streets of New Braunfels is a quintessential Texas trip. It’s a short 35-mile sprint up the I-35 corridor, but for Tesla drivers—especially those of you renting a self-driving-capable Model 3 from us at Frontier Tesla—knowing exactly where to plug in makes all the difference. You want speed. You want convenience. Most importantly, you want to spend more time floating down the Comal River and less time staring at a charging progress bar.
We’ve spent countless hours navigating this route. What we’ve learned is that not all charging stops are created equal. Some are designed for a quick "splash and dash," while others are perfect for a sit-down meal. Here is our comprehensive guide to the best Tesla Superchargers San Antonio to New Braunfels, optimized for your next Hill Country adventure.
The Fastest Tesla Charging Stations on the Route to New Braunfels
When speed is your priority, you need to look for V3 Superchargers. These are the gold standard of Tesla’s charging infrastructure, capable of delivering up to 250kW of power. If you’re asking where the fastest Tesla charging stations on the route to New Braunfels are, the answer lies in two specific locations: Schertz and New Braunfels itself.
The Schertz Supercharger, located at 1548 FM 3009, is a strategic powerhouse. It features 12 stalls, all of which are V3. Because it’s situated right off I-35, you don't have to deviate more than a minute from your path. Further up the road, the New Braunfels Supercharger at the legendary Buc-ee’s (2785 N Interstate 35 Frontage Rd) offers 16 V3 stalls.
Why does V3 matter? In a Model 3 Long Range, these stations can add up to 75 miles of range in just five minutes. That is faster than it takes to walk inside Buc-ee's and find the restroom. If you are coming from downtown San Antonio, these two stops are your best bets for minimizing downtime.
Clocking the Charge: How Long Does it Take to Add 50 Miles?
One of the most common questions we get at Frontier Tesla is: "How long does it take to add 50 miles of range at a San Antonio Supercharger?" The answer isn't a single number; it depends entirely on which station you choose and your car's current state of charge (SoC).
If you are using a V3 Supercharger (250kW), like the one at San Antonio - I-10 or the Schertz location, adding 50 miles typically takes between 5 to 8 minutes. This assumes your battery is preconditioned and your SoC is below 50%. Tesla’s charging curve is aggressive at the bottom; the emptier the battery, the faster it drinks.
However, if you find yourself at an "Urban" Supercharger, such as the Broadway location in downtown San Antonio, things slow down. These are capped at 72kW. At an Urban station, adding 50 miles will take approximately 15 to 20 minutes. It’s still efficient, but it’s a different pace of life. We recommend the Broadway stalls if you’re grabbing coffee at a nearby cafe, but stick to the V3s if you’re on a mission to reach the Schlitterbahn gates.
Navigating San Antonio’s Supercharger Network
San Antonio is a sprawling city, and its Supercharger placement reflects that. Depending on where you pick up your Frontier Tesla rental downtown, you have several distinct options before you even hit the highway.
The Broadway Urban Supercharger
Located at 1010 Broadway St, this is the most convenient stop for those staying in the Pearl District or downtown. It’s an Urban charger, meaning it’s slower (72kW), but it’s surrounded by incredible amenities. You can plug in and walk to local favorites like Rosella Coffee or Voodoo Doughnut. It’s about the experience here, not just the electrons.
The I-10 West V3 Supercharger
If you’re starting your journey from the northwest side of the city, the I-10 West location (11745 IH-10 West) is your speed demon. With 12 V3 stalls, it’s one of the most reliable spots in the city. It’s located near a variety of shopping centers, making it easy to grab road trip snacks while your car hits peak charging rates.
The Rim and Stone Oak Locations
For those heading north via Highway 281 or Loop 1604 before merging onto I-35, the Rim (17503 La Cantera Pkwy) and Stone Oak (22610 US-281) stations offer high-speed V3 charging. These are often busier during weekend shopping hours, so check your Tesla’s center display for real-time stall availability before you commit.
The Schertz Midway Point: A Strategic Necessity
Halfway between San Antonio and New Braunfels lies Schertz. For many, this is the "sweet spot." If you forgot to charge overnight or did a lot of city driving before heading out, the Schertz Supercharger is your safety net.
What makes this location stand out isn't just the 250kW speed. It’s the proximity to Evo Entertainment. You can literally catch a few trailers or play a quick round of arcade games while your Model 3 replenishes its pack. We’ve found that this stop is rarely congested compared to the San Antonio city chargers, making it a favorite for our frequent renters.
Arriving in New Braunfels: The Buc-ee’s Experience
You cannot talk about Tesla Superchargers San Antonio to New Braunfels without mentioning the New Braunfels Buc-ee’s. It is a rite of passage. With 16 V3 stalls, it is the largest and fastest charging hub in the immediate area.
The beauty of this location is the synergy. You need to stop for Beaver Nuggets and a brisket sandwich anyway; why not charge at the same time? By the time you’ve navigated the aisles of Texas-themed home decor and secured your fountain drink, your Tesla will likely be at 80% or higher.
Pro Tip: The Buc-ee’s stalls are popular. If you see they are full on your navigation, don't panic. The turnover is incredibly high because the chargers are so fast. Usually, a spot opens up within two or three minutes.
Beyond the Supercharger: Tesla Destination Chargers in New Braunfels
Superchargers are for the journey, but Destination Chargers are for the stay. If you’re planning to spend the day exploring, you might be wondering: "Are there Tesla destination chargers at popular spots in New Braunfels?" The answer is a resounding yes.
Destination chargers are Level 2 chargers (usually 8-16kW) that are intended for longer stays. They are perfect for topping off while you eat, shop, or sleep.
Gruene Historic District
Gruene is a must-visit. Between the iconic Gruene Hall and the Gristmill River Restaurant, you could easily spend four hours here. Several local bed and breakfasts and hotels in the Gruene area offer Tesla Destination Charging for their guests. While public chargers in the heart of the district can be limited, checking apps like PlugShare or the Tesla app will reveal hidden gems at nearby lodges.
Landa Park and Downtown New Braunfels
If you’re heading to Landa Park for a picnic or a ride on the miniature train, you’ll find destination charging at several nearby hotels, including the Courtyard by Marriott New Braunfels. This allows you to walk to the park or the Comal River tube chutes and return to a fully charged vehicle.
The Faust Hotel
For a touch of history, the Faust Hotel downtown is a landmark. They have historically been supportive of EV infrastructure, providing a convenient spot for visitors to plug in while enjoying the local nightlife or a meal at the hotel’s brewery.
Why Battery Preconditioning is Your Best Friend
Here’s the thing: you can be at the fastest 250kW charger in the world, but if your battery is cold, you won’t see those speeds. This is where the Tesla technology shines.
When you use the in-car navigation to select a Supercharger, the car automatically begins "preconditioning" the battery. It uses energy to bring the battery to the optimal temperature for rapid ion movement. We always tell our Frontier Tesla clients: always navigate to the charger. Even if you know exactly where the Schertz Buc-ee’s is, put it in the GPS. It can be the difference between a 10-minute stop and a 25-minute stop.
A Comparison of Charging Stops: San Antonio to New Braunfels
To help you decide where to stop, we’ve broken down the key metrics for the main stations on this route.
| Location | Type | Max Power | Stalls | Best For |

Understanding the Cost of Supercharging in Texas
While we provide our Frontier Tesla rentals with a seamless experience, it’s good to know how the billing works. In Texas, Tesla typically charges by the kilowatt-hour (kWh), though some older stations might still charge by the minute.
On average, a full "tank" for a Model 3 will cost you significantly less than a tank of premium gasoline. Expect to pay somewhere between $12 and $22 for a substantial charge, depending on the time of day. Some stations offer lower rates during "off-peak" hours (usually after 7 PM and before 10 AM), which is something to consider if you're looking to save a few dollars.
Overcoming Range Anxiety on I-35
If you’re new to EVs, the idea of "running out of juice" on a highway can be daunting. But on the San Antonio to New Braunfels route, range anxiety is practically impossible. You are never more than 15 miles away from a high-speed charger.
The Tesla Model 3s we rent at Frontier Tesla come with long-range batteries that can easily handle this round trip three times over without needing a charge. However, we encourage people to try the Superchargers anyway. It’s part of the Tesla experience—seeing the tech in action and realizing how effortless the future of travel actually is.
