Charge anytime, anywhere.

DELTA Pro’s Smart Extra Battery benefits from all the charging methods DELTA Pro has, including 6500W MultiCharge.

That means you can charge anytime, anywhere as long as your extra battery is connected to DELTA Pro.

Once connected, they’ll charge/discharge in unison, keeping the battery percent level across both units.

Ready for any emergency.

When the going gets tough and you’re out of charge options, get a 1800W DC fast charge with EcoFlow Smart Generator (sold separately).

Just plug the generator directly into your extra battery via the port on the back.

This works even when disconnected from your DELTA Pro.
