It moves a capability once limited to the Cybertruck onto Tesla's two volume models. The feature is tied to Powerwall 3, so it suits homes already using Tesla's battery rather than acting as a [stand-alone backup box](https://www.trendhunter.com/trends/delta-3-max). With up to 11.52 kW of continuous output, it is meant to carry real household loads in a blackout. In daily use, the car can sit in the garage like [stored reserve power](https://www.trendhunter.com/trends/Grid-connected-home-batteries), stepping in when the grid drops without changing its role as everyday transport. Tesla guarantees it on qualifying Model 3 and Model Y vehicles in the US and Puerto Rico. The covered orders start on October 1, 2026.
