  • Best value and performance in solar and easy to use
Well I am not going to try to write a technical review, I will leave that to people who know more than I do. But after reading those technical reviews and studying other solar products, it was a no brainer to pick Ecoflow. I wanted a very portable system that had a long life span and high efficiency rating. The Delta 2 was perfect for my needs. I can also say that for someone that is not technically inclined that the set up and use of the Ecoflow was very easy and I am happy with the expandability of the product . Also, I was surprised that even on a cloudy day the Ecoflow was generating power. Now I am tempted to go with a whole house system from Ecoflow. ... show more

  • Great product
Love it Quality product. ECO app is great accommodating. Ease of use is simple. Theres a comfort in knowing you still have some power when you lose power. I bought mine with an extra battery and a solar panel. Works great. Charges up with the wall outlet too not just solar. App provides many settings to choose whats best for you. I charged over night with wall outlet. Both units. App Set to 200w woke up in the morning and was good to go. Has an auto shutoff so i didn't need to worry. I tested this out with my air purifier on full blast handled it no problem. Ran purifier on boost charged my phone and a flashlight for more then an hour ECO used 3% battery life. ... show more

  • Compact
I just opened it today. Will charge soon. Heavy but manageable. I love that I can use solar panels to charge. I purchases the main unit and the back up battery. Helpful to use with our small refrigerator to keep medicine and food cold. Many uses Incase of a disasters specially earthquakes and occasional power outages. Will do a follow up after charging and trying it out. So far I feel satisfied with this choice. ... show more

  • The battery gives you extra run time
I purchased this because I'm getting older and sometimes when the power goes out you don't want to drag a big generator out just to run a few creature comfort items. The exact battery allows me an opportunity to get a few things working if the power is out for just an hour or so

  • Doulble Your Delta II Capacity
This will double the Watt Hours of your Delta II power plant - remember, this must be coupled to one. I bought mine on a 40% off flash sale - these occur with some frequency.

I stand corrected - EcoFlow support has reached out and they are taking care of the issues. I will report back once the return is complete.

  • Great Product
There are several things I love about Ecoflow: 1. The packaging that the items are delivered in is incredibly durable, no cheap boxes or cushioning. 2. The Ecoflow Delta 2 with the extra battery will power everything in my house with pure sine wave clean Electricity and surge capability. 3. Powers the electrical needs of my RV including the compressor Air Conditioner that surges at about 800 watts with about 300 watt high setting. 4. The material that they are made of is the best I have seen with a great stackable design. 5. Plenty of sockets for AC, USB, and Car inputs. 6. Will save my food from melting in a power outage by running my Freezer and Refrigerator (Keeping the door closed to extend the operation). 7. Can power my HDTV, computers, corner lamps to keep the home lit. 8. Solar Charging capable with the great Ecoflow Panels. I recieved the product with a 30% charge then brought it up to 100% in just 1 hour and 15 minutes. Will discharge it to 30% for long term storage when needed. I also will budget the number of units that are plugged in to it not trying to power everything I have to keep me going during an emergency. Overall,Ecoflow manufactures the best products of this kind ever and keeps coming out with great new items to consider. ... show more
