I love this unit. Robust build, great app and all the battery backup I need. This is connected to a fishtank to ensure power continues in the event of a failure. In the few months I've had this in place, it's already saved the tank once! Highly recommended!!

this is a comment about the support team; I bought the ecoflow delta 2 max and the 800w panels; I had a few set up questions, and the ecoflow team were proactive with assistance; they went above and beyond my expectations; lovely people to deal with;edit: this is great kit, and the software is well designed; i have made a frame from unistrut, (see picture - not finished) and connected it up at a remote site; with a data sim running from the 12v power socket (more efficient) and cameras running via the 230v inverter outlet; to run the Ecoflow unit without a mains connection, you don't need the Powerstream unit, but you do need a cable (link to follow) to plug each solar panel to the Ecostream;update: the remote operation has been successful throughout November and December, operating a camera and sim router (RUT950) without needing a top up; the specs show that it will not recharge when below 0 degrees, which seems to be the case, sunny, but minus six degrees in the shade;Charging temperature0°C - 45°C (32°F - 113°F)

I mainly got this to pair it with the powerstream, and it works as advertised and reduces my electricity bills. Although it comes with a hefty price tag I haave got it on a sale .. still the ROI will be at 5+ years but I am happy with the product itself. Portable solar generator with modern LFP battery technology with over 3000 cycles available, it can be completely discharged and recharged every day for 10 years and even then it’s only down to 80 percent capacity. . 2kw capacity and will work up to 3.5kw using X Boost; It can handle start up spikes up to 4.8kw, has full Bluetooth and Wi-Fi connectivity, it is expandable up to over 6kw, 2x 100w USBC ports, 4x USB A with two of those fast charge, 4x UK AC outlets. Someday I might take this on a camping as advertised if I will get a caravan, these days its sitting in my powered garden shed and providing electricity to my house.

Good product for extra power for the Delter 2 range

The battery works as advertised, very efficient and more importantly, very quiet. It could deliver enough power for multiple appliances at the same time. The app could help you to understand how it is doing and control it remotely.My unit has problem with solar panel charging, I contacted EcoFlow through Amazon and they responded quickly. A new replacement unit is quickly arranged.I am very satisfied with the product and customer services from EcoFlow. If you are considering batteries for home/off-grid use, this unit is highly recommended.

Exceeded my expectations, lasted a very long time

The media could not be loaded. I bought 2 of these with the Delta 2 Max for up to 6Kw of home back up power. I have 14 Ecoflow Solar Power Batteries Powering My Electric Good around my home and now using minium amount of electricity from the Grid.These extra Add On batteries are for the Delta 2 Max and can be also used with other Ecoflow Units too.

I got this for our Delta 2 after seeing it would work with itThe delta 2 is 1024wh so this allows the delta to access an extra 2048 .It does not increase the wattage of the machine only its available capacity.You cant daisy chain more of them to it ,as delta2 has just one input socket.I believe the bigger deltas can as they have more .Thi unit has a screen but you dont get sockets on it, only the connecting socket for the cable that joins it to the generatorOnce connected, it charges and discharges via that one cable. you cant charge it on its own from the mains it only charges via that cableWhen using the delta 2, the screen shows input and output to and from it and remaining time at that rate of activity. and you can also see the same sort of info in the delta 2 screen which also shows remaining and rates.It has been totally reliable so far allowing us to use the cheaper night time leccy in the day time..This unit is very heavyYou can sit another one on top if you have that sort of set up.We have it on the floor and the delta 2 on top.I was thinking we would use the whole set up in the camper but it is too big in our vehicle so we will stick with just the main unit in there.Excellent for prepping.There would be nothing stopping a person from charging it then unplugging and charging another one if they have the delta 2 as we do and not the bigger machines.Only space limits it.
