Tesla Cybertruck Powershare finally backs up homes with a Powerwall 3

Tesla’s Cybertruck Powershare feature can now back up your home at the same time as a Powerwall 3, the company announced Thursday. Run together, the truck and the battery add more than three days of backup power, which Tesla says is the equivalent of nine extra Powerwalls. It’s a feature Tesla first promised for 2025, and it’s showing up nearly two years after Cybertruck deliveries began.
