Powershare - Vehicle to Home/Grid Charging

Frequently Asked Questions

Powershare is Tesla's technology that enables your compatible Tesla vehicle's battery to provide power whenever and wherever you need it. You can use Powershare to power a campsite, pre-game tailgate, construction equipment, other electric vehicles or your home during a power outage.
Powershare is currently available for all Cybertruck vehicles, and all new Model 3 and Model Y² vehicles ordered on October 1, 2026 or later.
To verify if your vehicle has Powershare, navigate to ‘Software’ > ‘Additional Vehicle Info’ > ‘Powershare Support: Enabled’ on your vehicle touchscreen.
Cybertruck All-Wheel Drive and Cyberbeast vehicles have two 120 V outlets (up to 20 A) in the cabin along with two 120 V outlets (up to 20 A) and one 240 V outlet (up to 40 A) in the cargo bed.
All other eligible Tesla vehicles can use a Mobile Connector and Tesla Outlet Adapter to turn your vehicle’s charge port into a 120 V (up to 20A ) outlet.
With Powershare, you can power your home, electronic appliances, tools, other electric vehicles and more.
Cybertruck All-Wheel Drive and Cyberbeast vehicles can use the 240 V outlet in the cargo bed to charge other electric vehicles and/or heavy appliances with up to 9.6 kW of power.
During a power outage, Cybertruck can provide backup power to your home with up to 11.5 kW of power for over three days.¹ With Powerwall, Cybertruck can extend your backup duration by over three days and Model 3 and Model Y² vehicles can extend your backup duration by over two days.
Note: Estimate based on 30 kWh energy use per day. Results may vary based on your actual energy use. 11.5 kW is maximum power. Estimates assume Tesla vehicle has a full battery.
Powershare Home Backup refers to the hardware and functionality that detects a power outage and allows your Tesla to automatically power your home when plugged into a Wall Connector or a Universal Wall Connector. To set up the Powershare Home Backup functionality for your home, Powershare equipment is needed and sold separately. If you already have a Powerwall and a Wall Connector, no additional equipment is needed for Powershare Home Backup.
Using Powershare to charge electronic appliances, tools, electric vehicles and more from the built-in outlets is free. Simply make sure your vehicle is charged to provide power.
Using Powershare Home Backup requires Powershare equipment and installation. Installation costs depend on the installation configuration and complexity. Without Powerwall, installation costs typically range from around $2,000 to $4,000 USD. Your Certified Installer will be able to provide you with a quote for the installation cost after assessing your home. Hardware typically costs $1,950 USD but can be less if you have existing equipment already installed. Learn more about Powershare Home Backup equipment and installation costs.
For homes equipped with Powerwall and Wall Connector, no additional equipment is required. Powerwall 3 is compatible with your Powershare vehicle to provide home backup, and Powerwall 2 and Powerwall+ are coming soon. Compatibility with Powerwall is enabled via over-the-air update.
Cybertruck owners can enable Powershare Home Backup with Powershare Gateway and a Universal Wall Connector.
Tesla works with trained Certified Installers to install our home energy and charging products. If your home is eligible, a Tesla Certified Installer will take care of the installation as the process for Powershare Home Backup varies depending on your current setup at home. Installation costs will vary.
