Introducing the EcoFlow DELTA Max Lithium Generator! The DELTA Max gives you 2000-watts of power in a convenient portable outfit. This powerful generator allows you to charge, and power appliances where access to power is restricted, or simply not available. It’s perfect for providing back-up power to homes and emergency medical camps that are off grid. Power construction tools, refrigerators, computers and more! Harvest the power of the sun by connecting solar panels to give the Delta Max greater runtimes, or to simply store the power for when access to power is required.

Home emergency power
DELTA Max expands up to 6kWh with smart extra batteries, keeping your home powered on in any emergency.

Rapid dual charging
Charge up from 0-80% in 1 hour. Or get up to 3600W speeds by combining AC charging and the EcoFlow Smart Generator.

3600W Max (AC + Smart Generator)*
*DELTA Max needs to be connected to the DELTA Max Smart Extra Battery for dual charging.

Power multiple devices
Looking for something to power heavy-duty devices like your fridge and dryer? With X-Boost, DELTA Max handles devices up to 3000W with ease.

Portable solar generator
Stay powered on no matter what. DELTA Max connects with up to 2x 400W EcoFlow solar panels to deliver 800W Max solar charging speeds.

Backup your home during power outages with DELTA Max. With an expandable capacity that reaches up to 6kWh, dual charging, and the ability to power your home devices, you can stay powered on in any situation.

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. 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 and fast dual charging.
DELTA Max charges up safely and rapidly from 0-80% in just 1 hour. 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, AC with solar, or the Smart Generator with solar.

Power 99% of your home devices.
With EcoFlow’s X-Boost technology, DELTA Max can power heavy-duty devices up to 3000W. 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.

Harness the power of the sun.
DELTA Max connects with up to 2x 400W EcoFlow solar panels to deliver 800W Max solar charging speeds. With a voltage range from 11-100V and the MC4 connector, you can also connect other solar panels to your DELTA Max. Even during cold or cloudy days, our smart maximum power point tracking (MPPT) algorithm automatically detects voltage and current in real time to give you optimum solar generation throughout the day.

Emergency backup power.
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.

Control, monitor, and manage your energy use.
Control and monitor your DELTA Max with the EcoFlow app. Dive into the settings to customize your power use or control DELTA Max remotely.

Ways to Charge

There are multiple ways to charge DELTA Max wherever you are. If you’re at home, plug into an AC wall outlet or solar panels. If you’re out and about, charge DELTA Max in your car or use solar panels if you’ve set up camp. In extreme emergencies during power outages, connect the DELTA Max to the Smart Generator for a last-standing power source.
