Turning heads at the R/C races!

I just purchased the EcoFlow Delta 2 Max along with the 220W BiFacial Solar panel and took it to our National event for R/C Racing in Rome, NY this past weekend. Me and my buddy charged our 2S and 4S batteries at 10Amps throughout the 4 day event and only required to use A/C power to charge the unit 1 time (due to cloudy day) over the 4 day event. The Delta 2 Max kept up with 2 separate chargers, soldering irons, and phone charging each day! Plus it was quiet and sat on our table. Super pleased with this product!

I bought this and installed it into my daughter's bus. (Schoolie conversion) It is what we wanted. The only complaint that I have is the way the cable comes out the side. you cannot stack anything next to them within a foot. The wave has a nice 90 degree cable that goes between the battery and AC but the Delta 2's cable sticks about 6 inches out the side.

Amazingly long running

Already own a Delta, which is a five star product. But after a recent storm left us without power longer and run time shorter than expected we needed more. Well the more we found was in a Delta 2 Max. After receiving it we tested it on our frig, Whirlpool 22cf side by side circa 2008. 10hrs afterward it had 50% battery remaining. Decided to go all in and connect our 2 160w solar panels in serial purchased for our Delta. Started charging once sun was up at 220w. Solar started charging when battery was at 32%, 1 hr later battery at 37%. We've been in and out of frig adding groceries so it has run nearly non-stop for 4 hrs at 150w but our Delta 2 Max is recharged up to 55%. Sun is setting and input has dropped to 190w. So staggered at the performance, longevity and portability we went all in and bought the 2 add-on batteries and another 160w solar panel. FYI haven't used app and don't care to. Plan on getting manual switch over for whole home backup.

We had a five hour power outage about a week after receiving my battery. It worked just fine. I am very happy with it.

Delta II Max w/Smart Battery and 400W Solar Panels

I received everything and it all works great. I spent a lot of time researching different brands, options, performance, YouTube videos, etc. and I am very happy with EcoFlow. The only complaint I have is that the Delta II Max does NOT have wheels. EcoFlow sent me a canvas wagon where you can fit the generator inside but you cannot add the Smart Battery with it.
