The unit itself works pretty well. I'd like to see some of the lab features released and a few more things added. Namely the ability for it to keep charge settings even if it loses power. Might pick up the external battery later for added capacity.
We purchased the Delta 2 Max as an alternative to an overhaul of our RV's electrical system. We've used the unit a couple of days and it looks like it will be sufficient to enable us to boondock for two to three days. The case is sturdy, well made and not too heavy given the performance of the components. The app / smartphone interface is great.
Got this for power outages. Very nice that it has two solar ports. It does what it is supposed to do. Frame is well built. Very easy to use. I only use solar to charge it. Thank you.

I live full time on the road and I needed 24-hour power to run my eco flow glacier cooler and charge laptop phone microwave etc I have a 400 watt solar panel from another company. I thought the ones on eco Flow looked kind of flimsy and had bad reviews. But anyway the Delta max 2 works amazing last 5 days on a charge, 5% charge to 100% in an hour and a half plugged in to AC. Also charge about 4 hours from solar panel. Very quiet hardly noticeable
I bought 2 weeks ago, charged the panels just laying them on my driveway. Next day discarded run on my water pump, the generator worked flawlessly & the generator & panels were really well packed & easy to set up.
