Came in handy in the most unexpected way.

Not too long after recieving my delta 2, my parents were having a new electrical wire run. A hole had to be drilled near the electric panel to get the wire from the attic and into the panel location, little did we know some wires came in from a different direction. one well placed hole later took out all the kitchen outlets including the fridge and, until all the circuits had been removed from the panel and repaired, the ENTIRE HOUSE could not be cut back on. I grabbed the delta 2, did a fast charge up to full (Amazing to charge in the blink of an eye) and took it over to power the refrigerator for the duration of the repair. I wasn't expecting it to get used so soon, but it ended up being so much easier than trying to get out a generator and run cords through the house. we just set it on the counter, connected the refrigerator and were good to go. They actually have a whole home generator, but since the problem was inside the house the generator was useless. Having this much power be so portable and usable anywhere is truly amazing. We have since used it a bit more, including connected to solar and as a UPS during a final exam in the middle of a storm. The ease of everything really is the value here, there's no messing around with modes or configurations to go from power station to UPS to solar to car charging. Everything just works and gets out of your way.

Perfect backup

After a lot of research I purchased the Delta 2 as a backup for my farmhouse. We have power outages here every winter and I use a duel fuel generator to run my pump for water. But keeping that noisy generator running constantly is just too annoying. So I got this eco flow for quiet efficient energy when I don’t need the big generator running. I have used it through this winter and it is perfect- extremely easy to use, enough energy for my basic house needs, and chargeable by solar or from my larger generator. And when not in use, it is very simple to store and light enough for me to move easy. Thank you for this excellent introduction to solar alternatives. I look forward to expanding in this direction.
Works as described! Well designed compact unit with all the necessary ins and outs. I would have given it 5 stars except the solar panel to battery connector wasn’t included, though every other kind of connector was! Since I bought it with the portable solar panel, it would have been nice to have that Included, or at least to have been notified that I’d need to purchase that connector.
I'm not a gadget person. When I got the DELTA 2, I found it easy to follow the instructions to charge it and discharge it, running various appliances. Laptops were fully powered in a couple of hours. I plan to use it at home during power outages, so, not very often, but I will make sure to follow the maintenance instructions. I love that the unit recharges so quickly. I thought the DELTA 2's heat and noise when running were mild, very acceptable. The unit feels sturdy and has convenient handles for moving it. I like the EcoFlow phone app. I made a cheat sheet for my own appliances (e.g. freezer, single cooktop, etc.) so I know what I can power with it, and for about how long. I keep the cords, instructions, etc. in a pouch attached to the unit.

Not suitable as a UPS for sensitive electronics

I was hoping to replace an aging APC UPS with this EcoFlow Delta 2. Options like solar charging and the longer lasting LifePo4 batteries were a big step up from the old school UPS I am currently using. Unfortunately the internal transfer relay is not nearly fast enough to switch from mains to inverter while keeping my home networking gear online. While EcoFlow does not list this unit as a UPS, or suitable for UPS duties, it is a little disappointing that the unit cant switch fast enough for my intended use. I'm still glad to have it for the other backup and emergency uses it brings though.

Sump pump backup and way more!!
on July 22, 2025
Posted by: BillyDee
I bought this Delta 3 plus about a month ago for a sump pump backup system and its so much more than I expected. I have had a few severe storms in our area and the Delta 3 plus has done what I expected and more. I love the App and being able to control the D3P,, plus the stormguard on the app works great. It automatically charges the D3P to 100% when a major storm is detected within 12 hours!!! Thats awesome!! If you're at all skeptical about getting one don't be because it is a life saver or a basement saver in my case. It's my first Ecoflow purchase but Definitely not my last.

I received my Delta 2 a week ago and I am happy I went with Ecoflow over other competitors. Ecoflow Delta 2 is perfect size for home back up and camping generator if your in the market for one. I’ve done a home test on my full size fridge at 100% charge it will power for 10hrs. Can’t wait to use it for the real reason I purchased it and that’s for future camping trips I will be referring friends and family to Ecoflow. Thank you Ecoflow!!!

Peace of mind

I bought the Delta 2 after a day-long power outage, sleeping without my CPAP and worrying about the food in my fridge. I did a lot of internet research and it seemed th ebest fit for me for peace of mind, as well as supporting the CPAP on camping trips. While I've not had to use it yet, I can tell you that it is fact to charge, holds the charge like a champ (no power drain over a month) and is easy to move around the house. I love the display and the many ports to draw power from. My only regret is that the app does not seem to work with my phone/wifi network. Which I don't really care about, but thought would be cool.
