Tesla Launches Folding Superchargers for Faster, Cheaper Installs

Tesla introduced "Folding Unit" (FU) Superchargers, a pre-assembled, foldable approach to its "plug and play" charging strategy, aimed at expanding the world’s largest and most reliable EV charging network more quickly and at lower cost.

According to the @teslacharging account on X, the design makes installation faster, cheaper, and better. The foldable format lets Tesla ship 16 Supercharger posts on a single truck, up from 12 previously, reducing logistics costs for pre-assembled hardware.

The Benefits of the Folding Unit (FU)

The FU Supercharger advances the pre-fabricated units Tesla has deployed for years. Max de Zegher, Tesla's Director of Charging, said the units save 20%+ on cost, improve build quality, and deploy 2X faster.

On-site labor drops because there is no DC busbar connection required in the field, and a Tesla service technician is no longer needed for commissioning. A site can be placed in a parking lot, connected to power, and activated almost immediately. This is the Rev1 version of the hardware, with Rev3 slated to launch by next quarter.

A new 8-stall Supercharger in Columbia, SC this week appears to be among the first—if not the first—sites using the FU hardware.

Accelerating the V4 Transition

The rollout aligns with Tesla’s total transition to V4 hardware. Earlier this month, the company assembled its final V3 Supercharger cabinet at Gigafactory New York and committed to installing only V4 stalls and cabinets going forward.

The V4 system is a major upgrade: while a V3 cabinet could power four stalls, a single V4 cabinet can handle eight, matching the eight-post-per-unit layout of the Folding Units. V4 hardware supports 500 kW peak charging for 800V vehicles like the Cybertruck, while S3XY owners will continue to see 250 kW.

Scaling for a Multi-Brand Future

Faster installations matter as Tesla continues opening its network to additional brands, most recently adding Dodge, Jeep, and Fiat. V4 stalls also use cables that are three feet longer to better reach charging ports on non-Tesla vehicles.

With per-stall costs already the lowest in the industry at under $40,000, and the ability to deliver 16 stalls per truck, Tesla is positioned to maintain leadership in public charging.

As Tesla pushes toward 100% EV adoption, these logistics and engineering refinements enable scaling beyond what traditional construction can match. Expect these foldable units to appear at new sites globally before the end of the spring.
