The terms “DELTA” and “RIVER” as mentioned on this page refer to products exclusively manufactured by ECOFLOW INC.
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 solar 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.

Customer Reviews
I recently purchased the Ecoflow Delta Max Portable Power Station, and I am incredibly impressed with its performance. The battery life is excellent, and it can quickly charge all of my devices multiple times. The compact and lightweight design makes it easy to take on the go, and the multiple outlets and USB ports are very convenient. I also appreciate that it is eco-friendly and doesn't produce any emissions. Overall, I highly recommend the Ecoflow Delta Max to anyone needing a reliable and portable power source.
As a person from Ukraine, I would say it is a perfect fit for our situation with frequent power outages.
I'm from Ukraine, so it really helps my family now to survive and work remotely during constant blackouts.
2 KWh is enough to feed 2 laptops+Monitors, natural gas heat equipment, some lights, router, Starlink, and
occasionally microwave for 8-10h.
The passthrough function works also well, I use it as a really powerful UPS and sometimes don't realize moments when the electricity is on and off.
A recharge time of 1.5h helps to disturb neighbors by noisy Ecoflow generator work just for a small amount of time.
Above were pros
My contras -
- power surges protection system might be improved. I have to use an external voltage protector to get stable work when electricity puts on
- it's quite expensive
- there is no shipping to Ukraine, so I have to use outside agents' service which made it even more expensive
So the rate is 4
Die EcoFlow DELTA Max ist variabel einsetzbar und kann mit unterschiedlichen Stromquellen geladen werden!
In der App müsste noch die Temperaturanzeige von Fahrenheit in Celsius geändert werden.
I like it, but I would add the possibility to manage the settings directly on the device, therefore without a smartphone and to be able to recharge from the car alternator.
EcoFlow is a gamechanger! It makes using solar energy SUPER simple - they are portable and easy to use and great! Fully recommended!
Sehr gutes Produkt und ebenso guter Service und Kundenfreundlichkeit.
Ich habe jetzt 3x DELTA max (2000) im Einsatz und bin sehr zufrieden.
