Boost Your Power Capacity
Expand your DELTA Pro's capacity to 7.2kWh or even 10.8kWh by adding the Smart Extra Battery. This gives you enough power to keep your essential appliances running for days, ensuring you’re always prepared.
Charge Anytime, Anywhere
The Smart Extra Battery benefits from all of DELTA Pro’s charging options, including 6500W MultiCharge. As long as it's connected to DELTA Pro, you can charge both units together, keeping their battery levels in sync no matter where you are.
Emergency-Ready Power
In an emergency, fast-charge your Smart Extra Battery with the EcoFlow Smart Generator (sold separately). Connect directly to the extra battery through the port on the back, even if it’s not connected to your DELTA Pro, and get a 1800W DC charge when you need it most.
Real-Time Info at Your Fingertips
Stay in the know with a bright LCD screen that shows output, input, remaining charge, and time remaining. For more detailed information on the go, the EcoFlow app provides even more insights, keeping you informed at all times.
