I bought my battery back up and extra battery a week or two before our 1st major windstorm here in Buffalo. Just wanted it to run the sum pump only. Well, during the storm the power went out for 3 days. Yes the pump kept running for all 3 days. I do have a generator but only brought it out just in case I had to charge the batteries. For the three days the batteries went from 100% to 22%. Fantastic products!

I've been waiting for this soon as i got this i had to try it so i charged just something to use to to save food in my freezer and refrigerator from full charge i powered my fridge,tv,routers,and charged phones 6hrs np i know there's more out there but this works for me im simple, price was right i already had panels im not real technical this will be fine

This setup is used to power our refrigerator and freezer during power outages. The Delta 2 and extra battery is charged with an EcoFlow 160 watt panel and/or a propane powered generator AC port. The Delta 2 is easy to manage through the app and I hope to purchase an additional solar 160 watt solar panel and an EcoFlow Smart bi-fuel generator to supplement our setup.

As expected a little smaller than my 160 Watt panel I got with my generator but the two connected together will work fine. VERY impressed with Ecoflow and would highly recommend them for your back up power needs. Works so well we're considering Solar for our house.

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.

Incredibly capable system for the size and price. I’ve been running a compressor and saws for a cabin build. It’s been great to ditch the generator. Will use it for cabin electrical at the end of the project. The app is functional but lacks fit and finish. Moments of lag, time remaining sometimes doesn’t sync. The entire firmware update process is abstruse.

Light/portable. Set up is a little wonky. Could use some better instructions. In full light and the correct angle, output was right around 100w. This panel would be great for temporary charging of a small EF station (River or Delta), and has MC4 connectors plus an mc4 to x60 adapter.

I use a gas generator in the morning to charge my Ecoflow River Plus. Then when the sun hits my solar panel it will keep up with most of my power needs until late afternoon when I need gas generator again. Solar panel not aimed directly at sun but I still get up to 77 watts input mid day

Great Unit! But,....Needs a few tweaks to make it a Five Star for me. I hate that every time you turn on the unit from the front control panel, you have to reach behind to push a little button that is hard to find so you can turn on the 120 volt power. I bought this to power up our Christmas Lights in our fifth wheel slide out that has no 120volt power in the slide. the thing that sucks, we push it way back to hide the Delta-2 and all the cables. it is easy to turn it off at night as it turns off with the push of the main power button.. the nightmare in when we need to pull it all the way back out every day to try and hunt down the 120 volt power button. PLEASE CHANGE THIS ON FUTURE UNITS.

Like others are saying, the shipping was delayed by a few days then I only received the solar panels, no power station. Then they want me to initiate a return, but I don't have the full item to return and I can only imagine how that would be handled when they receive only the panels. I have FedEx looking for the lost package but doubt it was ever sent since this seems like a recurring problem for the vendor Sams is using.
