The Big Picture
DELTA Max's large 2kWh capacity keeps your home appliances running during a blackout. Expand up to 6kWh with Extra Batteries for several days of reliable backup power.
Expandable Home Backup Power
A single DELTA Max unit packs a 2kWh capacity that is expandable up to 6kWh with DELTA Max Smart Extra Batteries or DELTA 2 Max Smart extra batteries. This means when a blackout hits, you can continue to power your important home devices such as your fridge and lights for hours on end.
Convenient & Fast Charging
DELTA Max charges up safely and rapidly from 0-80% in just 65 minutes. And it gets even better. If you're looking for an even faster way to charge up DELTA Max, you can combine AC with the smart generator to get up to 3400W, AC with solar to get up to 2600W, or the Smart Generator with solar to get up to 2600W.*
Your Devices When You Need Them
With EcoFlow's X-Boost technology, DELTA Max can power heavy-duty devices up to 3400W. That means during a power outage or blackout, you can continue to power your fridge, dryer, and more. That's the industry gold standard for a portable power station of this size and capacity.
Power in an Emergency
Disasters can occur at any time of the year, sometimes lasting longer than we ever expected. When extended blackouts hit, the EcoFlow Smart Generator serves as an emergency option that integrates with DELTA Max. It auto-starts when your DELTA Max hits a low level of charge, recharges your DELTA Max, and stops the engine all by itself once your DELTA Max hits a full charge. This gives you a reliable emergency backup option that relies on minimum use of a generator.
