Check your host model first

This is an expansion battery, not a standalone AC power station. More watt-hours can extend runtime, but do not increase the main station's rated output. Confirm the exact host model, firmware and required connection accessories before ordering; a similar DELTA name does not establish compatibility.

Connecting two extra batteries requires the appropriate EcoFlow Smart Extra Battery Expansion Adapter. Confirm compatibility with the configuration you intend to use. You can also browse currently listed DELTA stations.
