We purchased the power station last year while preparing for hurricane season. This extra battery is a welcome addition to our disaster preparedness kit. Easy to operate, packaged perfectly.

Very portable due to lower weight. No trouble at all for this 70 year old to move. Just one hour to charge. Very pleased.

Was looking forward to hook this up to one of my solar panels. It's connected to my Ecoflow Delta 2 max. Unfortunately it doesn't have a solar input. I think the extra battery is not charging from the max 2. Contacted customer service and I hope they advice.

Works! Immediately 'recognized' by Delta 3 1500 and integrated into main battery management system. Quick charging, too.

I'm so happy the EF ECOFLOW DELTA 2 Smart Extra Battery is back in stock. I had purchased 2 units of the DELTA2 last year but the extra battery was sold out. I was worried since thy came out with eco 3 that they wouldn't have anymore of the EcoFlow Delta 2. These EcoFlow save my food last year when Fl got hit with 2 hurricanes back to back. We lost power for 4 days. I had one hooked up to refrigerator and other on deep freezer. Had the EcoFlow Delta Max running everything else. Thankfully I saw Amazon having extra battery back in stock with the $150 off. I was able to grab one and back today to grab the other. These are truly lifesavers. Get them while you don't need them vs need them and didn't buy them :)

i ordered the the extra eco battery with my other unit. i ran a small air purifier on low and it didnt even last 18 hours. from 8:30 am to around midnight. that is very pitiful. it does charge quickly but that is because the battery is obviously very small. that's why it is light. if i could i would return the main unit and the extra battery. as far as i'm, concerned this is a joke and maybe approaching towards a little bit of a scam. i got ripped off as far as im concerned. i have a blueti and it has been running my air purifier for 5 days now. it really wasn't but a few dollars more than both of the eco units. get the blueti.

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.
