Tesla has officially energized its first 500kW V4 Supercharger station. Located in Redwood City, California at 2545 El Camino Real, the site features eight V4 Supercharger stalls powered by Tesla’s newly designed V4 cabinets, capable of delivering up to half a megawatt of charging power to compatible vehicles.
Tesla announced the opening on X, showing the Cybertruck plugging in at 1% state of charge and quickly reaching 500kW. Unfortunately, the video cuts off there and no information was provided on how long the Cybertruck was able to sustain that high level of charging, or what the charging curve looks like after that.
It costs US$0.32/kWh to plug in during off-peak hours, or US$0.48/kWh during peak hours.

Until now, Tesla’s V4 Supercharger posts had been deployed worldwide but were still tied to legacy V3 cabinets. These capped vehicle charging speeds to 325 kW, despite the V4 pedestals being designed for much higher output. The debut of the V4 cabinet changes that equation entirely.
The new V4 cabinet features three times the power density of V3, with double the number of stalls per cabinet. Yet, despite this, it takes up less space and has a smaller footprint. Each cabinet contains 16 trays of power electronics, converting AC to DC with higher efficiency and lower cost. This design streamlines deployment, making it easier for Tesla to expand the Supercharger network faster and more affordably.
As Tesla engineer Max de Zegher noted, the V4 cabinet is the foundation for future ultra-fast charging. The system supports up to 500 kW for passenger vehicles today, and up to 1.2 MW for Tesla’s Semi trucks, paving the way for widespread adoption of megawatt charging across industries.
While the Redwood City site is capable of delivering half a megawatt of power, only one Tesla currently on the road can actually use it—the Cybertruck. Other Tesla models, such as the Model 3, Model Y, Model S, and Model X, are still limited by their battery architecture to lower charging rates.
For now, the site only supports Tesla vehicles, but the company has confirmed that non-Tesla EV owners will gain access starting in Q4 2025, once final engineering validations are completed. When that happens, Redwood City will become one of the fastest charging locations available to the broader EV community, not just Tesla drivers.
This launch comes as a surprise to many in the Tesla community. Just last week, construction began in Campbell, California on what was expected to be the world’s first true V4 Supercharger site with V4 cabinets. That station is still underway, but Tesla quietly flipped the switch in Redwood City first, one day ahead of the end of their target to open the first V4 station in Q3 2025.
