AUSTIN, Texas — Tesla has switched on one of the Cybertruck's most requested capabilities: the electric pickup can now pair with a Powerwall 3 to keep a house running during an outage. The official Cybertruck account announced the update on X, saying the pairing "extends your home backup by over 3 days, equivalent to 9 additional Powerwalls." Cybertruck lead engineer Wes Morrill confirmed the rollout, calling it the first time a vehicle and a home battery have worked together this way.
The feature turns the truck into a genuine energy asset, deepening Tesla's push to blur the line between its vehicles and its home-energy hardware. That strategy runs across the company, from residential storage to the grid-scale products detailed in Tesla's Megapack 3 and Megablock ramp.
Why the pairing matters
A single Powerwall typically covers a home for about a day, less during a heat wave or deep freeze. Adding a second Powerwall for more storage can cost several thousand dollars installed. With this update, a Cybertruck owner instead taps a battery they already own, one large enough to add roughly three more days of backup without mounting another unit or booking an installer.
For households in wildfire, hurricane, or winter-storm regions where outages can stretch past a day, that difference keeps refrigerators running and medical equipment powered. As Teslarati reported, Powerwall 2 and Powerwall+ compatibility is still on the way later this year.
