Introducing the EcoFlow DELTA Pro Smart Extra Battery. It's the perfect solution for those who need extra power on the go. This powerful battery pack features a high-capacity rechargeable lithium-ion battery, allowing you to charge your devices quickly and efficiently.

With its sleek and lightweight design, you can easily take it wherever you go. The DELTA Pro also features a smart charging system that automatically adjusts the output to match your charging device, ensuring optimal performance. Get the extra power you need with the EcoFlow DELTA Pro Smart Extra Battery.

Expandable capacity - This add-on battery connects with a DELTA Pro to double total capacity to 7200Wh. Connect two of them to a DELTA Pro for a staggering 10.8 kWh of battery storage.

Convenient recharging - Recharging from solar panels, AC outlets, EV charging stations, or our Smart Generator is easy. Plug the Extra Battery into a DELTA Pro and they will recharge and discharge in tandem.

More watt-hours at home - The Extra Battery can be integrated into your home’s wiring when connected to a DELTA Pro using the EcoFlow Smart Home Panel. These battery units become part of your home’s peak shaving and emergency power solutions.

Ready for emergencies - This Extra Battery can recharge directly from EcoFlow’s Smart Generator outdoors, giving you another option for emergencies.

LCD screen - Get all the same info about battery percent, remaining recharge time, hours left, and more on the built-in screen. You can check the battery’s status anywhere from the EcoFlow app.

*Note: This product is exclusively for the EcoFlow DELTA Pro portable power station.

Make it a triple - Double or triple the capacity of your DELTA Pro to 7.2kWh or 10.8kWh. That’ll give you days of power for your essential appliances.


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 an 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.


Stay informed - The Smart Extra Battery sports a bright LCD screen on the front of the unit giving you all the info you need. Output, input, remaining charge and time remaining. It’s all there. Need on the go info? The EcoFlow app can tell you all that & a whole lot more.
