Expandable Energy Storage

Increase your DELTA 3 Plus/DELTA 3 capacity by 1024Wh, doubling your total energy storage to meet varying power needs. Perfect for off-grid living, emergency backup, and portable power solutions.

Effortless Setup & Plug-and-Play Functionality

No complicated setup required—simply plug the extra battery into your power station to instantly expand storage. Use the EcoFlow app to monitor charge levels and manage power settings with ease.

Remote Monitoring & Smart Control

Stay informed with real-time updates on battery percentage, remaining recharge time, and usage hours via the built-in display or EcoFlow app, allowing you to manage power from any location.

Multiple Recharging Options

Conveniently recharge the extra battery by connecting it to the power station's extra battery port. Power up using:

  • AC outlets
