Purchased about a month ago after extensive research. Delta 2 and Smart Extra Battery arrived but would not communicate with each other. Email to customer service and they immediately sent a new cable. Cable arrived in 5 working days. Hooked up perfectly, charged rapidly..1.5 hours to charge from 30% to 100%. Ran cPap for three nights before needing a recharge. Tested three times with same results. Cpap has a heated reservoir and heated tubing. Based on past experience, disabling these functions will cut energy consumption in half.

So glad I purchased this power station!! Within 2 weeks of receiving it, we had 6 days of power outages in our neighborhood, plus some other random hours of outages throughout the month. During this time, I was able to run my CPAP all throughout the night, plus charge many other items, phone, battery fans, plug in lamps, and other small appliances. Even a couple of neighbors came by to charge their phones. It made a huge difference! So easy to use and a variety of types of outlets. Next I plan to purchase the add-on battery and the solar charger. A great buy!!

During hurricane Ian we had no power and no cable service and could not watch what was happening around us. Since then I bought an antenna to hook to a tv but knew I would not run generator till storm was over. EcoFlow DELTA 2 solves power problem I ran TV for 2 days to test and it worked great.

I use this power station to power my tool shed so it runs lights, recharges tool batteries, my EV bike battery and also runs any corded tools. it is small and light weight so I can take it with me when I am working away from home. It puts out enough power to run a a small welder. I have two 100 watt solar panels on top of the shed so it is always kept at 100%. the Bluetooth and internet interface lets my check on it no matter where I am. The fast charge is amazing and really works as advertised. I am thinking of getting the extra battery just to insure enough power but so far it severs my power needs as is.

I just purchased Ecoflow Delta 2 recently. I’m very impressed how easy to use and operate and charge quickly for 1 hour or less. The only problem I have is using Wi-Fi connection. The Bluetooth was easy to connect. I have my tv, and Wi-Fi router, stand up light , portable radio, cell phone chargers in case of power outages. I’m glad this was my choice of back up power , instead of gas generator. It’s portable and I can take it anywhere with me. I’m learning slowly, but have not tried yet on solar panels. I’ve been testing my Delta 2 power station turning off power at home to see how long it will power my equipment without the electricity for several hours. I got my information from YouTube watching ecoflow videos before purchasing this product. It’s worth the price!

I bought this to replace a smaller unit that could not backup my fridges or freezers. It is much lighter and more functional than the Delta 1300 I purchased a few years ago. I prefer the LiFePO battery and it's associated longer life. It does not have as much battery capacity as the Delta 1300, but the inverter appears to be the same. I like the ability to set the charge limit to 70% while using it as a UPS. The UPS functions very quickly and has been running a freezer and some other appliances without problem. It was a little slow to update the firmware when I got it, but it seems to be doing fine now. I don't like that one must connect the device via WiFi to get updates. It wants access to my home network and that is forbidden to the Chinese (and other) companies. Overall, I like it and it works so far as a UPS for my freezers and fridges.

Very good for backing up necessities during a power outage, and I plan to use it instead of installing an inverter in my truck. I have a river 2 max for my CPAP, and already had a EF220 watt solar panel for that, so when I got the D2 I purchased a second 220w portable panel. Charging from the grid, solar, or an inverter generator is pretty quick and easy. I can now run my refrigerator, small chest freezer, and CPAP with plenty of extra capacity for “comforts” and have more options than just firing up a generator (which isn’t always easy or convenient, and definitely not quiet).

I bought these items about 4 to 5 weeks ago and so far it has good a great investment. I live in Florida, we have hurricanes every year and power goes out, sometimes up to 5 days. Now I can rest assured that my family will have power. Thank you Ecoflow for making such a great items. Plus putting them on sale so the working class people can make this investment.

The set up was pretty easy but for the large amount of booklets etc that come with it there is VERY LITTLE information. Need to see what it can and can’t be used for, troubleshooting etc I haven’t fully charged it yet-trying to do solar but I needed the extension for the solar panels. I have the unit and back up battery and with my less than perfect solar panel position it has been charging about 1/3 of one battery inn6 hours

I purchased this about a mouth ago and have yet to use in a power outage. I have tested it on my refrigerator and freezer which worked fine. The flaw is it will not run my natural gas fired boiler that heats my house. From what I researched I found that it needs a pure sine wave AC current and the Delta 2 output is a modified sine wave. I have yet to find a cost efficient solution to this issue.
