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.

Ordered EcoFlow DELTA Max. Received the order faster than expected. Thank you!
How amazing, from the start of the purchase to receiving my delta, very good service and reliable company and delivery courier. Had 300watts of sun power three days ago from the solar panels ( 160w X 2). Brilliant power from one of the market leaders.
We were hit badly by Storm Arwen and were without power for days. The Ecoflow Delta Max was everything I hoped it would be. We could use our oil fired central heating, boil the kettle, use the microwave and even watch TV and because Ecoflow was transportable I could easily pop it in the car and take it to get charged at a friends some miles away. Thank you Ecoflow.
This is a second unit for us, works perfectly and has doubled my portable power capacity thus increasing the time I can go off grid camping in our van
Excellent!!!!!!
All I required and more.
What a fantastic bit of kit, wouldn’t be without it now.
Everyday use for remote office is ideal.
Very quick delivery and well packaged .
Works very well powering things in my motorhome and I even plug my van into it to top up my leisure battery 👍
Great battery system, fast charging when needed, powers all electrical items I have used so far without issue. Currently connected to 420 watt Solar panel and so easy to set up and with the app see exactly how much charge is going in and what power consumption you are are using. Looking at getting additional battery pack but so far rarely dips below 60% even though I am using 2.2kw kettle, 2kw toaster and 1.8kw coffee machine on the battery. End of day I have approx 70% battery left so charge up overnight at 400watts at my cheap rate 7.5p/kw and use power all day saving money as day rate is 36p/kw.
Very pleased so far need to see how it fares in the winter months
I received the power unit three days before it was expected. I have now unpacked (packing excellent) checked the contents, inspected the unit and read the handbook. All perfect. I will test the unit when time permits. I expect no problems.
looks a very nice piece of kit, not had chance to use it yet, but looking forward to going off grid, using the EcoFlow
Very easy to use - good app and instructions (and I'm still challenged when trying to understand electricity terms and calculations). Charged it up when our solar panels were producing a surplus, then tested by plugging in various things including the dishwasher (not perhaps the first thought in an emergency, but I wanted to see if it worked) and it powered a short eco cycle using about 40% of its charge. It also told me that it could power our small freezer for about 50 hours. Now thinking of more uses to justify its purchase including power for a small greenhouse heater in case of frost or taking to outdoor events. Will be invaluable of course in case of power cuts. Didn't realise from the pre-sale info that it also can act as an Uninterruptible Power Supply (UPS) for crucial equipment (e.g. medical) by simply plugging it in between the appliance and the mains socket. It's pretty pricy but a high quality piece of kit.
The Delta Max 2000 is amazing..
I'm powering most of the basics in the house (the VirginMedia Router, 2x PC Monitors, laptop, TV and Surround Sound System).
Fully charged I can get a max of 12 hours of either the TV & Surround Sound kit or the Gaming Laptop with the Dual Monitors (each configuration shows a 140w power draw.
I also have a 405W mono Roof solar panel which can charge the unit very well or maintain the charge on a cloudy day but also looking to get the 400 Watt EcoFlow folding Panel
Amazing power and it is very easy to used. I want to buy another want but ecoflow should give discount price.
Excellent for powering essential appliances during the increasingly common power cuts this year, and also in preparation for when the shtf. Really good design. Great service, thank you.
Incredible! Get one.
This kit is the best addition to my motorhome. I use it off grid run heating hot water microwave and lighting. As it it hooked into my 240v mains in socket it is like being plugged into shore power. I am so impressed with the build quality and pure power from this that I have also ordered an extra battery giving me an incredible 4032wh. Well done for an excellent product that makes offgrid very much ongrid!
Haven’t had a chance to do anything with it
