Tesla has officially opened its first Supercharger with next-generation V4 cabinets in Redwood City, California, delivering charging speeds of up to 500kW for cars. Located at 2545 El Camino Real, the installation marks the world’s first fully V4-powered Supercharger site — nearly two years after Tesla debuted its first V4 stalls with longer cables in the U.S.
Unlike earlier deployments that paired V4 stalls with legacy V3 cabinets, this site is powered by Tesla’s new V4 Supercharger cabinets. Each cabinet can support up to eight stalls, double that of V3, with three times the power density and significantly lower deployment costs — reportedly under $40,000 per stall. The cabinets also pave the way for 1.2MW charging for the Tesla Semi.
The Redwood City installation beat out another site with V4 stalls and cabinets under construction in Campbell, California, discovered just last week, to officially become the world’s first fully V4 Supercharger to go live.
Tesla’s Director of Charging, Max de Zegher, shared the first official look inside one of these V4 cabinets. The image shows a tall white enclosure containing 16 trays of power electronics — described as a “charging masterpiece” by de Zegher. The cabinet takes AC power in, converts it, and outputs DC to vehicles, enabling 500kW charging for passenger cars and supporting 30% faster charging speeds for Cybertruck.
Tesla says the new hardware will allow for faster deployments with a smaller footprint and higher efficiency, while also being the most reliable charging technology the company has built to date. For owners of Model 3, Model Y, Model S, and Model X, charging rates remain capped at 250kW, though Tesla notes these cars can still add up to 200 miles of range in just 15 minutes. The Cybertruck, meanwhile, will be able to take advantage of the V4 cabinet’s full 500kW output.

For now, V4 cabinets only support Tesla EVs, but the company confirmed that non-Tesla EV compatibility will follow in Q4 after final engineering validations are complete.
The rollout comes as Tesla continues scaling its charging infrastructure worldwide. Earlier this summer, the company began deploying its first V4 stalls in China, and just last week, Tesla Superchargers started appearing on U.S. highway signs for the first time. With V4 cabinets now live, global deployments of next-gen Supercharger sites are expected to accelerate rapidly.
