Tesla has officially started ramping up deployment of its next-generation charging infrastructure. The company’s Gigafactory in New York recently reached a major milestone by assembling its final V3 Supercharger cabinet, signaling a total shift in production toward V4 hardware. With the V3 production line now retired after a seven-year run, Tesla is prepared to blanket the globe with its most powerful charging technology yet.
According to longtime Tesla watcher @sawyermerritt, Tesla now has four V4 Supercharging stations open across the U.S. that are fully capable of delivering 500 kW charging speeds. These "all-white" towers are no longer just prototypes; they are active hubs for the next generation of electric travel.
Where to Find 500 kW Superchargers
The rollout of these high-speed sites has been steady, with the most recent openings happening in just the last couple of weeks. As of today, the 500 kW-capable sites in the U.S. include:
Kissimmee, Florida (Opened this week)
Gatlinburg, Tennessee (Opened last week)
Taylorsville, Utah (Opened in January 2026)
Redwood City, California (First site with V4 cabinets and stalls, opened in September 2025)
It is important to note that while these stations can output massive amounts of power, 500 kW charging is currently only available for the Cybertruck. Thanks to its advanced 800V high-voltage architecture, the Cybertruck is the first and only vehicle in Tesla’s consumer fleet capable of harnessing this level of power. Owners of the S3XY family will still see the familiar 250 kW peak rates they get on V3 hardware, which can still add up to 200 miles of range in just 15 minutes.
The Transition to V4 Everywhere
Tesla’s first V4 stalls went live back in March 2023, but those early sites still used older V3 cabinets hidden behind the scenes. The "true" V4 experience requires both the new stalls and the new V4 cabinets, which were officially unveiled in late 2024.
The new cabinets are a massive step forward in efficiency. A single V4 cabinet can now power up to eight charging stalls, which is double the capacity of the previous generation. This smaller footprint and reduced complexity mean Tesla can deploy new sites faster and at a lower cost — reportedly under $40,000 per stall. These units are also designed for better accessibility, featuring cables that are three feet longer than V3 Superchargers to reach various charging port locations and ergonomic, easy-grip handles.
A Universal Future
As Tesla continues to open its Supercharger network to other manufacturers, the V4 hardware’s versatility will be critical. The longer cables make it much easier for non-Tesla EVs to plug in without taking up two parking spots. Tesla is also bringing centralized payment kiosks to its V4 Superchargers, allowing drivers without a Tesla account to pay as they go.
With Gigafactory New York now 100% focused on V4 cabinet production, these high-speed stations will start popping up everywhere very soon. Whether you're driving a Cybertruck or a Model 3, the gold standard of public charging is getting a major upgrade.
