Bought it to keep on my boat while it’s moored offshore and we aren’t staying on it to run genset. Was hoping for it to keep mini fridge running while gone so I don’t have to empty it everytime we leave the boat. Problem is if you have a few cloudy days and solar can’t keep up and you kill the battery it won’t automatically turn the outlets back on even after getting charged from solar… there is no WiFi to connect. So I wouldn’t count on this being a viable source of power for your off grid location unless you plan on being there all the time to monitor it.

We did the research, over and over, and the EcoFlow Delta 2 came out on top, over and over. So we just plunged and bought it. Love the type of battery it has!. Love the way it looks, love it's longevity, love that it MAKES NO GENERATOR NOISE, love that it is so expandable! We will take it camping, but we are also now strategizing how to set our house up with a stack and solar for alternate energy. Our power goes out often here and how nice it would/will be to have this slick alternative all set up to go!

Bought 2 Ecoflow Delta 2 units plus a 220w folding solar panel. I live in a hi rise condo that doesn't allow gas generators. The Delta 2 is perfect as it is quiet and safe. My balcony faces south in florida, so my solar panels get maximum sun exposure. Couldn't be happier!

I recently purchased the Ecoflow Delta2 to provided backup power to our home during power outages. So far it has exceeded my expectations. The battery has lasted longer than expected so I'm looking for more things to power. A nice feature that I wasn't expecting is the UPS feature. I have my mini frig plugged into the Delta 2 so that when power goes out, the Delta 2 automatically switches over from home AC power to battery backup. Although the battery lasts longer than expected, the ability to add extra batteries in the future was a key feature since I didn't know what my power requirements will be in the future.

I’ve only had the Delta 2 for almost a week now, but I’ve tested it out for days with discharge and charge without issue. Fast charged and battery-friendly rate charge were both pretty quick. Total adjustability is a great feature. App is working good with no issues between the app and product.

I originally bought this to be a power source for camping. However, i got to use temporarily until my power came back on to run my pellet stove. Easily movable and easy to use. Download the app and it's a good way to keep an eye on usage and anything else. I like that I will be able to expand it if needed. Right now it's good for what i need.

I purchased this as a combo with the 220W solar panel a few months ago. It charges incredibly quickly via wall outlet and is easy to hook up a solar panel to. The screen is easy to read and the app is very convenient to monitor power input and delivery as well as control different features, such as charging/discharging limits or switching the different power ports on/off. I also purchased a weather-resistant cover which is nicely made. The top compartment is very convenient for storing cables. Here are some of the parts I dislike. The Auto Timeout feature is nice but can still trigger if you are powering something with low current, such as a string of LED lights. The app frequently takes a swipe down refresh to reconnect. Annoyingly, reconnecting to the station after leaving it overnight will sometimes be impossible until you physically power cycle the station. Even more annoying is if there are cables plugged in it can be difficult to power off the station until you unplug all cables. I have also noticed when camping with it, in the morning it did not start charging with direct light on the panel until I disconnected one of the solar panel cables and reconnected. The solar panel I purchased with it shows signs of the material around the grommets failing after a couple uses. It seems like a lot of weight to rely on grommets to hold up, especially when mounted in a semi flexible material. Overall the station itself is well built and has plenty of power for long term use. It has some annoying quirks, especially when using the app, but the unit itself is very good at what it does.

I bought this unit after the major storms in California in 2023 as our house lost power for 4 days, and running the generator was neither efficient, nor did the job well. The plan was to use the Delta 2 to power the refrigerator and to charge the computers and flashlights. Specfically we wanted a battery that had fast recharge time so that we could both recharge from solar, and if the sun wasnt shining recharge it off the generator in a timeframe that didnt require us to keep refilling the gas tank and having to listen to the generator all day. The Delta 2 works great! it recharges off solar faster than we are depleting it, and its so convenient that I have been using it instead of grabbing an extension cord to work outside on nice days. the display is intuitive, the app connects flawlessly, and the functionality is perfect. Its a really well thought out product that i would definitely recommend. I did a ton of research into other units from other brands and am happy I settled on EcoFlow.

I've bought battery for a whole home backup. I started with Bluetti EB70 and soon faced lack of capacity so decided to move to Delta 2. It was surprisingly to get only 200Wh extra capacity "on paper" and actually get 2x times more longer working time for appliances. Also you'he possibility to extent capasity 2 or 3 times with extra beaateries as well. Also a big plus of Delta 2 is interesting feature - if I plug something that needs more power than Delta 2 can output - it will still work at maximun output. So you still can use your applience (not in full power but still). As a small improvement I can suggest integrate small lamp into battery. Usually it's really hard to plug socket in darkness so small light may be very useful. P.S. It also has more comfortable sitting place for my cat.

Hi, EcoFlow! I've already mentioned to your support, that your products are amazing. Be a Ukrainian and do not know the brand - it's a shame (: I bought Delta2 and Extra Battery 3 months ago and these guys help every day to survive the power outage and stay online, with heat and light. Really convenient to use. Look and feel are great. Efficiency is the top.
