EF ECOFLOW DELTA Pro Extra Battery 3600Wh, 2.7H to Full Charge, Battery Backup for Home Use, Blackout, Camping, RV

With a extra battery, DELTA Pro can expand capacity from 3.6kWh to 7.2kWh for battery backup power supply.

That’ll give you days of power for your essential appliances.

DELTA Pro’s 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.

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.
