EcoFlow DELTA 3 Smart Extra Battery
Expandable Capacity
Increase the capacity of DELTA 3 Plus/DELTA 3 with an extra 1024Wh. Double the
capacity to meet your energy storage needs—ideal for home backup, RVing, outdoor
adventures, and everyday use.
Compact Design

stacked on top of the power station to save space and reduce clutter.

stations with similar capacity and output.

station for more energy storage. Use the EcoFlow app to monitor and control the

more—right on the built-in screen or from the EcoFlow app, wherever you are.
